wards the apex, where it is emarginate ; spread out spathulato- 

 obovate, with folded or undulate margins ; colour white, with a yel- 

 low line down the centre. Column very short, furnished with an 

 erect small tooth on either side of the anther, with an extremely 

 long curved foot, which is three-veined, bifurcate at the apex. 

 Stigma occupying almost the whole face of the column. Anther 

 sub-immersed, cucullate. Pollinia 4, pyriform, curved. 



The flowers, which vary a good deal in size in distinct in- 

 dividuals, have the smell of Dendrobium crumenatum, but to 

 a less powerful degree. 



I have adhered to the usual terms in describing the co- 

 lumn, although they are scarcely applicable, the prolonged 

 foot belonging partly at least to the labellum and lateral 

 sepals. Mr. Brown's character of Dendrobium, Prodr. Fl. N. 

 Hoi. p. 188, may have some reference to this, which, as it re- 

 gards a diversity of origin of a structure much used in gen- 

 eric definitions, is worth investigation. 



The following are the Indian species of this genus. 



A. Leonis, foliis patentissimis breve et late scalpelliformi- 

 bus obtusis, floribus terminalibus, labello lineari-oblongo 

 pubescenti fimbriato-dentato apice emarginato subdilatato.

Stems a span long. Leaves sometimes so much approximated 

 that the stem resembles a coarse double-edged saw : varying in 

 size, but always broadly and shortly scalpelliform. Flowers reddish 

 brown (Lindl ), subsessile. Petals oblong-lanceolate, twice as broad 

 as the third ovate sepal. 



A. anceps, foliis scalpelliformibus asccndenti-patentibus 

 acutis, floribus terminalibus vel axillaribus, labello cuneato 

 emarginato crenulato.
