WARSCEWICZELLA WENDLANDI DISCOLOR. [Plate 126.] Native of Costa Rica. Epiphytal. _Stemless_, ebulbous, producing only a tuft of leaves and flowers from the crown of the roots. _Leaves_ cuneate, oblong-ligulate, acute, somewhat plicate, broad and channelled below, amplectant at the base, of a light green colour. _Scapes_ solitary, issuing from the leaf axils, about half as long as the leaves, and furnished in the upper part with a two-valved bluntish spathe, which is rather shorter than the united ovary and pedicel. _Flowers_ moderately large, measuring from four to five inches in their broadest diameter, stellately expanded, interesting from the peculiar form of their lip, and pleasing from the contrast of their colours; _sepals_ lanceolate, “white,” the dorsal one erect, the lateral ones somewhat deflexed; _petals_ of the same form and colour, spreading, somewhat twisted; _lip_ projected forwards, ovate-cordate, the apex recurved, about an inch and a half broad, the edges multilobulate and much undulated, white, the centre plane, with at large oblong blotch of violet-purple marked longitudinally by about seven darker purple lines, the base constricted, white, with a short chin behind; frill or ruff small, with about seven to nine violet-purple stripes, semilunate, gradually diminishing backwards till lost in the chin or mentum. _Column_ white, thickened upwards, semiterete. Warscewiczella Wendlandi, _Reichenbach fil._, in litteris. Zygopetalum Wendlandi, _Reichenbach fil._, _Beitrage zu einer Orchideenkunde Central-Amerikas_, 74. — _Var._ DISCOLOR, sepals and petals yellowish green. Warscewiczella Wendlandi discolor, _Reichenbach fil._, in litteris ad cl., Smee. Both by Reichenbach in his various writings, and by Bentham in the recently published _Genera Plantarum_, the group named _Warscewiczella_ is included under _Zygopetalum_. Putting aside the question of minute botanical details, we prefer, in this case, to be rather guided by habit, since habit is so important a factor in all that concerns cultivation. Thus, while the species and varieties of _Zygopetalum_ produce pseudobulbs, those of _Warscewiczella_ are ebulbous, and this difference necessitates a material distinction in the mode of cultivation to be adopted for the well-being of the two groups.
