between the pollen-masses and the scale-like gland of the ros- 

 tellum, free from both, except in the centre. This pollinary 

 appendage readily shrivels up in drying, and has been generally 

 overlooked ; but I have always seen it very prominent and of a 

 bright yellow pollen-colour in Cymbidium giganteum, and, with 

 care, seen it very distinctly in buds just open of dried specimens 

 of several species of Cymbidium, Ansellia, and Grammangis. It 

 is also well figured in Blume's plate of Iridorchis, and in Griffith's 

 of a Cymbidium, Ic. PL Asiat. t. 321. Ansellia, Lindl., consists of 

 three or four marked varieties, or, possibly, distinct species, all 

 African and mostly tropical, very nearly allied to Cymbidium, 

 although the inflorescence is terminal on the leafy stems, and the 

 column, shortly and broadly produced at the base, is exceptional 

 in the subtribe. Orammangis, Rcichb. f., has also most of the 

 characters of Cymbidium, but has been rightly distinguished by 

 Reichenbach, chiefly by the form of the perianth. It was founded 

 on the Grammatophylliim Ellisii, Lindl., from Madagascar, to 

 which must evidently be added the Cymbidium Huttonii, Hook., 

 Bot. Mag. t. 5676, said to be from Java ; but both species being 

 only known from cultivated specimens, their origin may not be 

 quite certain. 



Cremastra, Lindl. {Ilyacinthorchis, Blume), a single Japanese 

 species, and Cyperorchis, Blume, from the Indo-Malayan region, 

 have been well distinguished by Blume from Cymbidium, to which 

 they had been referred ; and I cannot find in the dried flowers 

 any trace of the pollinary appendage of Cymbidium. To Blume's 

 typical species of Cyperorchis I would add Cymbidium elegans, 

 Lindl., C. Mastersii, Lindl., and probably C. cochleare, Lindl. ; 

 but I have not succeeded in seeing the pollinarium of the latter 

 species. 



Geodorum, Jacks, (including Cistella, Blume), nine species from 

 the Indo-Australian region, Grammatophyllum, Blume (including 

 Gabertia,Ga.\\dich., andPattonia, Wight), six Indo-Malayan species, 

 and Dipodium, Br. (including Leopardanthus, Blume, and Wailesia, 

 Lindl.), six species from the Indo-Australian and South-Pacific 

 regions, have all been well characterized, and require no comment. 

 Thecostele, Beichb. f, is a single Malayan species, with a very 

 curiously shaped perianth ; but I am unable to see any affinity 

 with the American Stanhopieaj (Eborilingues, Beichb.), with which 

 Beiehenbach associates it. It appears to me to be more nearly 

 related to Cymbidiea? than to any other subtribe, notwithstanding
