Z. Mackayi intermediuin, Hort. — A very fine and distinct 

 plant, having the leaves longer than in Z. Mackayi. The 

 flowers are of a paler colour than in the type, with a fine 

 large expanded lip, and are produced during the winter 

 -Brazil. 



7i, maxillare, Loddiges. — ^A free-flowering and handsome 

 species, producing its drooping spikes at different times in the 

 year, and keeping in beauty for a long time. We have had 

 this species with seventy flowers on a plant at one time. 

 It has oblong furrowed pseudobulbs, lance-shaped nervosa 

 leaves attenuated to the base, and large showy flowers on 

 radical scapes. The ovate oblong acute sepals and petals are 

 green, transversely blotched and barred with chocolate-brown, 

 and the lip, which has a blunt spur and a large roundish front 

 lobe, is of a rich bluish purple. The large frill or ruff on the 

 disk is of a deeper purple, crenate, shaped like a horse's hoof 

 (unguliform) and united to the small erect lateral lobes of the 

 lip. This will do well on a raft or in a basket. — Brazil.

Z. rostratum, Hooker. — A showy and rare free-flowering 

 species, which blossoms three times a year, and lasts six 

 weeks in perfection. This makes a fine exhibition plant when 

 well grown. We have shown it with twenty or more flowers, 

 and grown like this it is a beautiful object. It requires 

 more heat and moisture than any of the other species. The 

 plant has a creeping rhizome, forming at intervals an oblong- 

 ovate subcompressed pseudobulb. The leaves and scapes 

 appear on the young growths, the former lanceolate acute 

 plaited, the latter one to two-flowered, radical. The flowers
