flowering in great perfection, in October, 1834. It is a 
native of Brazil, and appears identical with the Z. crinitum 
of Mr. Loppices, which Professor Linptey has, 1 think with 
justice, considered a variety of Z. Mackait. Indeed the 
Evropnia Mackaiana of the Bot. Register (t. 1433) appears 
to be intermediate between the true Z. Mackati and our 
present plant ; which latter is distinguished from both those 
just mentioned by the more acute anther-case, by the entire 
- (not emarginate) lip, conspicuously hairy at the base, and 
marked with purplish-red interrupted and nearly parallel 
lines. Professor Linpuey considers the species of this Genus 
to be “ terrestrial,” to us they appear to be epiphytes.
