Variety (botany)

“ Many varieties of flowers may be recognized by the color of their seeds, as in the poppies, stocks and others. Other white-flowered varieties may be distinguished when germinating, their young axes being of a pure instead of a purplish green. It is a test ordinarily used by gardeners, to purify their flower beds long before the blooming time, when thinning or weeding them. Even in wild plants, as in Erodium, Calluna, Brunella and others, a botanist may recognize the rare white-flowered [147] variety by the pure green color of the leaves, at times when it is not in flower. ”

“ And yet the investigation that does not take into account varieties misses a large number of plants possessed of the most noteworthy and valuable individual traits. The question may be easily asked, Wherein lies the difference between a variety and a species? but the answer evidently is not so easy, when we consider that every individual plant varies in a degree from all other plants; and, to render it still more difficult, we find botanists very properly ignoring the existence of varieties that may have individual characteristics invaluable to the planter. ”

“ The best proof perhaps, of the unfavorable influence of external conditions for slightly deteriorated deviations is afforded by variegated leaves. Many beautiful varieties are seen in our gardens and parks, and even corn has a variety with striped leaves. They are easily reproduced, both by buds and by seeds, and they are the most ordinary of all varietal deviations. They may be expected to occur wild also. But no real variegated species, nor even good varieties with this attribute occurs in nature. ”

“ From the peculiar, tree-like character of the plants, the variety is remarkably well adapted for cultivation in pots; but its late maturity greatly impairs its value as a variety for forcing. It is a slow grower, tardy in forming and perfecting its fruit, and, for ordinary garden culture, cannot be recommended as being preferable to the Perfected and other earlier and much more prolific varieties. ”

“ On the other hand there is a larger group of cases of reversion by buds, which is probably not of hybrid nature, nor due to innate inconstancy of the variety, but must be considered as pure atavism. I refer to the bud-variations of so many of our cultivated varieties of shrubs and trees. Many of them are cultivated because of their foliage. They are propagated by grafting, and in most cases it is probable that all the numerous specimens [179] of the same variety have been derived in this way from one primitive, aberrant individual. ”

“ New varieties have been multiplying within the past few years from seed. Some gentlemen are raising varieties by thousands. Not more than one out of a thousand prove truly valuable. The quality of a new variety can not be established earlier than the fifth year. ”

“ The fruit of the cultivated varieties is generally smooth, or provided with a few stiff hairs, while that of the wild varieties has soft and shorter hairs; but intermediate forms exist, and it has been shown by experiment that by sowing the seeds of the cultivated fruit, plants with either smooth or hairy fruit are obtained.1363 There is, therefore, but one species, which has produced under cultivation one principal variety and several sub-varieties as to the size, colour, or taste of the fruit. ”

“ If several varieties of a plant are grown together, and the seed is indiscriminately harvested, it is clear that the hardier and more productive kinds will, by a sort of natural selection, gradually prevail over the others; this takes place, as Colonel Le Couteur believes (21/38. 'On the Varieties of Wheat' page 59.) , in our wheat-fields, for, as formerly shown, no variety is quite uniform in character. The same thing, as I am assured by nurserymen, would take place in our flower-gardens, if the seed of the different varieties were not separately saved. ”

“ Whenever a species produces one or many varieties, these varieties continue to vary always. The source of all variation, which is transmissible by sowing, resides in the seeds. The older a variety, the less the seedlings vary, and the more they tend to return toward the primitive form, without being able ever to reach that state; the younger or newer the variety, the more the seedlings vary. ”

“ In botany, an extensive and important natural order of exogenous trees and shrubs, found exclusively in the temperate and tropical parts of the Old World, and unknown in a wild state in America. The fruit is pulpy, succulent, sub-acid, and eatable, and separated into cells by membranous partitions, and is covered with a leathery aromatic skin or rind. Some of the genera embrace plants of great beauty and utility. A few of the Indian species are climbers. The genus CIT′RUS, which includes the orange, lemon, citron, lime, bergamot, and shaddock, is that best known in Europe. ”

“ When we take into consideration the multitude of species which compose the vegetable kingdom, even in any one country or climate, it is obvious that some arrangement, some regular mode of naming and distinguishing them, must be very desirable, and even necessary, for retaining them in our own memory, or for communicating to others any thing concerning them. Yet the antients have scarcely used any further classification of plants than the vague and superficial division into trees, shrubs and herbs, except a consideration of their places of growth, and also of their qualities. ”

“ Variegated plants, whether originally produced from seeds or buds, can generally be propagated by budding, grafting, etc.; but all are apt to revert by bud-variation to their ordinary foliage. This tendency, however, differs much in the varieties of even the same species; for instance, the golden-striped variety of Euonymus japonicus “is very liable to run back to the green-leaved, while the silver-striped variety hardly ever changes.” ”

“ As a single bud out of many thousands produced year after year on the same tree under uniform conditions, has been known suddenly to assume a new character; and as buds on distinct trees, growing under different conditions, have sometimes yielded nearly the same variety—for instance, buds on peach-trees producing nectarines, and buds on common roses producing moss-roses—we clearly see that the nature of the conditions is of subordinate importance in comparison with the nature of the organism in determining each particular form of variation ”

“ Taking these limits as the marks of the variety, and considering all fluctuations between them as responses to external influences working during the life of the individual or governing the ripening of the seeds, we get a clear picture of a permanent ever-sporting type. ”

“ If, with all the aids of art, these slight differences make a great difference in cultivating the several varieties, assuredly, in a state of nature, where the trees would have to struggle with other trees and with a host of enemies, such differences would effectually settle which variety, whether a smooth or downy, a yellow or a purple-fleshed fruit, should succeed. ”

“ If the selection is carefully made, the grower will soon rejoice, because he will observe a larger and a larger number of plants approaching the type of plant he has been selecting for. In time practically the whole plantation will be coming "true to type," and he will have developed a new variety. ”

“ Many monstrosities, such as fasciated branches, pitchers, split leaves, peloric flowers, and others constitute such ever-sporting varieties, repeating their anomalies year by year and generation after generation, changing as much as possible, but remaining absolutely true within their limits as long as the variety exists. ”

“ On this account less dependence is to be placed upon named varieties than in some other cultivated plants, and greater need is required to secure carefully selected strains. Owing to peculiarities of soil, climate and season, and the different degrees of care given by the different growers, seeds of the same variety may be better from one source than from another. On this account, when a variety is found adapted to one's needs it is well to use the same variety, and obtain it from the same source year after year. ”

“ This variety is a beautiful specimen of a single flower affording a developement of the organ of fructification; the petals are delicately penciled, and the anthers very bold, colour pink, and the flower very large; grows freely, and, in our opinion, is surpassed by none of the single sorts, for raising fine new varieties, if impregnated with the pollen from double flowers. ”

“ As a general rule only a few individuals of a species vary simultaneously in the same manner; and there is no improbability in the assumption that some few individuals might produce larger seeds than the average, better stocked with nourishment. If the production of such seeds were highly beneficial to a species, and on this head there can be little doubt, the variety with the large seeds would tend to increase. ”

“ He begins by distinguishing Herbs, Shrubs, and Trees. Proceeding to the detailed classification of Herbs, he divides them into Imperfect "which either do want or seem to want some of the more essential parts of Plants, viz. either Root, Stalk, or Seed," the Cryptogamia of Linnaeus; and Perfect "having all the essential parts belonging to a Plant." The Perfect Herbs are arranged in three main groups according to (1) their leaves, (2) their flowers, (3) their seed-vessel, each group being subdivided in various ways. ”

“ In these the axis remains short, nearly as it is in the bud; the leaves therefore remain close together in sets or circles; the outer ones, those of the calyx, generally partake more or less of the character of foliage; the next set are more delicate, and form the corolla, while the rest, the stamens and pistils, appear under forms very different from those of ordinary leaves, and are concerned in the production of seed. This view gives to Botany an interest which one who merely notices the shape and counts the parts of blossoms, without understanding their plan, has no conception of. ”

“ The Deviations, as they may be called, from the assumed type or pattern of flower are most various and extensive. The differences between one species and another of the same genus are comparatively insignificant; those between different genera are more striking; those between different families and classes of plants more and more profound. They represent different adaptations to conditions or modes of life, some of which have obvious or probable utilities, although others are beyond particular explanation. The principal modifications may be conveniently classified. ”

“ With regard to the quantity of seed per acre, great diversity of opinion exists among cultivators. Much, of course, depends on the variety, as some sorts not only have more numerous eyes, but more luxuriant and stronger plants, than others. ”

“ There is great uniformity in all as regards the flowers, so that the classification is based mainly on differences in the fruit and seeds. Many of the most valuable garden vegetables, as well as a few more or less valuable wild plants, are members of the family, which, however, includes some troublesome weeds. Cabbages, turnips, radishes, with all their varieties, belong here, as well as numerous species of wild cresses. ”

“ The consequence is, that it frequently happens that an accidentally abnormal variety, which may occur only once in the way in nature, having been cut up into a number of specimens, and distributed without notes to various botanists, has, from its presence in so many herbaria, all the appearance of a form abundant in the locality cited. ”

“ Whenever these variations tend towards greater productiveness, better quality or enhanced beauty, selection is again made of such specimens as give promise of supplying the wants and gratifying the desires of civilized man. The bettered conditions of the plant, by reason of man's effort, do not usually result in producing like variation along all lines. One part of the plant as the flower, the fruit, or the stem, varies more than the other parts. All this tends to break up a single type or stock into many varieties. ”

“ From these species, crossed and recrossed in various manners, have sprung the vast number of different varieties now enumerated in catalogues, whose characteristics are so inextricably blended that the attempt to trace their exact parentage or to follow out their lineage has become impossible. The varieties at present cultivated vary in the most remarkable degree in size, colour, flavour, shape, degree of fertility, season of ripening, liability to disease and constitution of plant. ”

“ Now it must be granted that the energizing of such a propensity under ordinary circumstances is quite another thing from the origination of a positive variety by the evolution of the same character. In the variety the activity has become independent of outer influences or dependent upon them in a far lesser degree. The power of producing the red pigments is shown to be latent by the facts given above, and we see that in the variety it is no longer latent but is in perfect and lasting activity throughout the whole life of the plant. ”

“ It is usually one of the first desires of the intending planter to inquire about Varieties. It is one of the secondary things to be considered, however, for the first thing to do is to prepare the land, to determine whether one’s soil and site are adapted to the plant in question, and to discuss other matters of a general nature. When all the fundamental things are settled, then the question of Varieties, which is a special matter, may be taken up. Although the selection of Varieties is a very special matter, it is nevertheless essential to success or satisfaction in the growing of any plant. ”
