1. H. lacertifera, -Sg^^/^ Tubers small, globular. Leaves few, oblong- 

 aiiceolate, 2 to 3 in. long. Stem 6 to 10 in., including a somewbat spiral 

 spike of 2 or 3 in. Bracts as long as the ovary. Plowers light green, about 

 \\ lines long; the sepals all connivent. Spur very short and vesicular. 

 Labellum rather longer than the sepals, with a raised protuberance on the disk, 

 and divided to the middle into 3 short linear lobes ; the 2 lateral ones diverging 

 and somewhat falcate. Anther-cells slightly diverging. — Coeloglossiim lacer-

2. H. stenostachya, Bentli. Stems 6 in. to 1 ft. (or more?) including 

 a many-flowered spike of 2 to 4 in. Leaves lanceolate, 2 to 3 in. long. Sepals 

 and petals about 2 lines long, linear, obtuse, rather thick, connivent or slightly 

 spreading. Bracts as long as the ovary, ending in a short fine point. Spur 

 slender, shorter than the ovary, usually about 2 lines long. Labellum nearly 

 equally 3-lobed ; the lateral lobes linear-lanceolate and divaricate ; the middle 

 one usually (perhaps always) short and obtuse. — Platanthira stenostachya,

Hongkong, Clmmpion. Also in IMoulmein {Loll, n. 363). I have not seen Hance's 

 specimen, but Reichenbach's first description as CcBJoglossum cermium agrees very well with 

 Champion's plant. The corrected description appears to have been somewhat modified to 

 include the C. peristyloides, Wight, Ic. t. 1702, a species from the Indian Peninsula, cer- 

 tainly very nearly allied, but differing iu the long middle lobe of the labellum, and some 

 other points. 



3. H, leptoloba, BentU., n. sp. Stem rather slender, 6 in. to 1 ft. in- 

 cluding a slender and rather long spike. Leaves lanceolate or linear, 1 to 3 

 in. riowers distant, with small bracts. Ovary shortly beaked. Sepals and 

 petals ovate-lanceolate, 2 lines long, the upper ones converging over the column; 

 the 2 lower spreading. Labellum rather longer, deeply divided into 3 narrow- 

 linear lobes, adhering at its base to the column with a minute tooth on each 

 side between the labellum and the anther. Spur 5 or 6 lines long, thickened 

 towards the lower end. Anther-cells very diverging, nearly horizontal.
