gland of the rostellum, in all the others they or their caudicles 

 are sessile on the gland. Zeuxine, Lindl., about sixteen species 

 from the Indo-Malayan region, includes Adenostylis, Blurne, a 

 name preoccupied in Composite^, Tripleura, Lindl., and Psyche" 

 clrilits, V. Breda. It has been well divided by Blume into three 

 sections, Zeuxine proper, Lafkrodes, and Psychechilus, to which I 

 would add, as a fourth, Monochilus, Wall. (Haplochilus, Eudl.), 

 distinguished chiefly by the rather larger flowers and the habit 

 approaching that of Goodyera. Cheirostyles, Blume, well charac- 

 terized by the perianth and the column, has about eight species 

 from the same Indo-Malayan region. Odontoclrilus, Blume, from 

 the Indo-Malayan and South-Pacific regions, should in elude about 

 ten species ; for, as far as can be judged from Blame's plates and 

 from dried specimens, I can find no sufficient character to separate 

 Cystopus, Blume. The genus comes very near to Ancectochilus, 

 both in habit and character, but the labellum has no spur. 

 MyrmecJiis, Blume, has two Javan species, JIT. gracilis and M. 

 glabra, Blume, which are identical with Uliamphidia alsincefoiia 

 and B. grandijlora, Lindl., respectively ; they have a peculiar 

 habit, and are much nearer allied to Odontochilus than to Hetceria, 

 to which belong the typical species of Uliamphidia . JTcsmaria, 

 Lindl., previously indicated by A. llichard, but not satisfactorily 

 published, under the name of Ludisia, extends from the Malayan 

 archipelago to China in four species, including Myoda, Lindl. 

 Dossinia, Morr., is a single well-known species, said to have been 

 introduced into our gardens from Borneo ; the Khasiya plant 

 referred to it by Lindley appears to me to be different ; but I have 

 only seen a single specimen, which I could not examine. Macodes, 

 Blume, and Hylophila, Lindl., are both monotypes from the 

 Malayan Archipelago. Goodyera, It. Br., is a genus of about 

 twenty-five species, spread over Europe, tropical and temperate 

 Asia, and North America, with perhaps a single (unpublished ?) 

 tropical-American species; for G. guianensis, Lindl., is Spiranthes 

 Hostmanni, Beichb. f., and G. Wrightii, Beichb. 1"., is also a 

 Spiranthes of the section Stauroglossum. Blume appropriately 

 united with Goodyera as a section Lindley's genus Georchis, dis- 

 tinguished chiefly by the form of the pollinary apparatus, but 

 running much into Goodyera proper ; he also proposed as a third 

 section, under the name of Ccenorchis, the G. pusilla, Blume, with 

 a long caudicle to the pollen-masses. One would also be tempted 

 to make a distinct section for the G.procera, Hook. {Cionisaccus,\. 

 Breda, Cordylestglis, Falcon., Leucostachys, Hoft'mans.), a tall, leafy
