Calceolaria

Definition and stakes

Various,  Encyclopaedia Britannica, 11th Edition…

“ CALCEOLARIA, in botany, a genus belonging to the natural order Scrophulariaceae, containing about 150 species of herbaceous or shrubby plants, chiefly natives of the South American Andes of Peru and Chile. The calceolaria of the present day has [v.04 p.0969] been developed into a highly decorative plant, in which the herbaceous habit has preponderated. The plants are now very generally raised annually from seed, which is sown about the end of June in a mixture of loam, leaf-mould and sand, and, being very small, must be only slightly covered. ”

“ Comparatively rarely do we find all the organs present; but when two flowers are united together we find every possible variety between the number of parts naturally belonging to the two flowers and that belonging to a single one. Sometimes instances are met with wherein the calyx does not present the normal number of parts, while the other parts of the flower are in excess. I have seen in a Calceolaria a single calyx, with the ordinary number of sepals, enclosing two corollas, adherent simply by their upper lips, and containing stamens and pistils in the usual way. ”

“ The normal coloration of the calyx occurs most frequently in polysepalous calyces; teratological coloration, on the other hand, occurs especially in gamosepalous flowers. This assertion is borne out by the frequency of the change in the plants already mentioned, and also in the following:—Campanula persicifolia, Anagallis arvensis, Gloxinia, Syringa persica, [297] Calceolaria, &c. &c. In the last-named plant one or more of the lobes of the calyx may frequently be seen replaced by a slipper-like petal. ”
