stalks, diverging, white, Avith a tinge of pink, sweet-smelling. 

 Bractes sub-reniforin, one-flowered. Petals five, expanding, 

 the upper one oval ; the next two rather narrower, but of the 

 same length ; the lower two sub-orbicular and much larger 

 than the other three. JVectary or lip very large ; its lamina 

 deeply three-parted, but closed like a case for the column of 

 fructification; lateral lobes obliquely wedge-shaped, and 

 truncate; the middle one sub-lanceolate with an incurved 

 apex. Horn incurved into a very perfect hook ; apex green 

 and somewhat obtuse. Column of fructification very short, 

 but protruded downward into a long concave receptacle for 

 the lower two petals and nectary. Lid beaked. Filament 

 single, rising with a bifid apex, from a beaked process, on the 

 interior part of the top of the column. Anthers two, globu- 

 lar, deep yellow. Stigma immediately under the beak. 

 Germ linear, twisted a little. 



J^ote. My Lhnodornm ohiusicornu no doubt belongs to 

 the same genus with this. They are both most beautiful while 

 in flower; in appearance obtusicornu has rather the advan- 

 tage, but the sweet fragrance of the flower of this lovely mo- 

 dest looking species must give it a decided preference. 



3. A. suaveolens. Hoxb. 



Parasitic, caulescent. Leaves bifarious, linear, bidentate. 

 Racemes lateral, filiform, drooping. Lamina horn-shaped, 

 unguiculate, with two oblong erect lobes at the base. 



Found on trees in the forests of Chittagong, where it per- 

 fumes the air with the delightful fragrance of its flowers, the 

 whole year round. 



Stems rooting, short, slender, and simple, somewhat suc- 

 culent, the whole length being only a few inches, and scarcely 

 thicker than a crow's quill, perishing at the base as they shoot 

 from the apex ; from the most succulent parts, the fleshy 

 roots issue, and fix to the tree that supports the plant. 

 Leaves bifarious, sessile, stem-clasping, linear, fleshy, smooth 

 on both sides; «/)c.r two-toothed ; from three to six inches
