644 ORCHIDES. polystachya' 



ancipitous flexuose scape. terminated by a few fragrant bright yeliow flowers streaked 

 wilh red. It approaches very near to the genus Polystachya, next to which among 

 Vandeae it raust be placed. The inside of the iiitle tridentshaped lip is bearded 

 with long hairs.

1440. Er£.OPHIA RBr. 

 Eulophus: B. R. VII. (1821.) tab, 573. sub Lissochilo specioso RBr. 



,.This genus in affinity comes nearest to those plants of South Africa at pre- 

 sent referred lo Limodorum and Cymbidium , namely Limodorum barbatum, triste, 

 longicorne, and perhaps also hians of Thunberg (not however Satyrium hians Linn., 

 which seems to be a Disa) , Cymbidium pedicellalum and aculealum. These along 

 wilh several Indian species, especiaily L. virens, carinatum and perhaps epidendroides 

 form a genus (Eulophus), relaled on the one hand lo Dipodium (vid. Prodr. flor. nov. 

 hoil. p. 330), and essentially agreeing with Lissochilus in ihe structure of anlhera, 

 but sufflciently different from it in its trilobed crested labellum, which is neilher cor- 

 daie, nor connected at base wiih the column. In boih tbese characiers, Lissochilus 

 equally difTers frora Angraecura of M. du Petit Thouars, which has also an elongated 

 spur and a considerably difl^erent habit. 



Eulophia RBr. Bot. Reg. VIH. (1832) t. 686. ,.for the outline of ihe genus and 

 enumeration of the species we refer to Mr. Brown's observalions on Lissochilus spe- 

 ciosus , vol. 7. fol. 578. of ihis work ; where the name is written ,,Eulophus'*, and 

 has been now altered in ihe terminaiion on ihe suggeslion of its auihor. 



Lindl. B. M. Comp. N. 19, p. 201 : Sect. Desciscentes. In Gen. et. Sp. Orch. this 

 section is characterized as having equitant leaves. I now tind, ihat allhough in some 

 species tlie leaves are truly so, yel that in many olhers, they are only folded togelher 

 and carinale.
