Summary

John Lindley Edwards's Botanical Register — Appendix to the First Twenty-three Volumes…

Three species only are yet known; all from Swan River, namely M. tridentifera, vestita, and glabrata,183 all small shrubs with three lobed or trident-shaped leaves, and numerous clusters of small flowers seated on filiform stalks; but with regard to the two Grevilleas which Brown calls Conogyne, and which Endlicher is inclined to refer to Manglesia, it does not appear to me certain that either of them belongs to it, and G. triternata certainly does not.

Another species, P. brevifolia,168 has flowers which, when infused in hot water, give out so brilliant a yellow colour that it is worth examination of a probable source of a dyeing material.
The Persoonias are plants of little beauty; P. Frazeri is the handsomest; P. macrostachya,172 like Petrophila brevifolia, seems to possess dyeing properties that deserve investigation.
