tissima has just (April 21, 1864) flowered with me and exactly 

 corresponds with the figure of that species in Dr. Wight's Icones. 

 It likewise so entirely corresponds with the figure of C. angusti- 

 folia in the same work that I cannot entertain a doubt of the 

 perfect identity, which Dr. Wight himself seemed to suspect, of 

 the two plants. At the same time it is probable that the plant to 

 which Achille Richard gave the name of C. angustifolia may be 

 really distinct, a matter of which Dr. Wight had no opportunity 

 of judging. C. odoratissima grows freely if not kept too w r arm ; 

 indeed I believe that it will be found to succeed perfectly in a cool 

 orchid-house, into which I was led to place it after hearing the 

 account of its habitat from General Cotton, who at once recog- 

 nized the species when looking through my collection the other 

 day. According to him this and other Ccelogynes are found in 

 large masses on the summits of the highest Nilgherry hills, but 

 always on the north side, and frequently growing among stones 

 and wet moss. It always flowered so punctually the second 

 week in April — the week in which was Mrs. Cotton's birthday 

 — that it enjoyed the designation of the 'Birthday Orchis' 

 during her and the gallant General's residence in India, and it 

 was interesting to me to notice that this year it opened its 

 flowers at Knypersley only a few days later than the date of the 

 auspicious anniversary in question. Next year I hope it may 

 keep exact time !" 



Descr. Pseudobulbs pale-green, about an inch long, very 

 much tufted on creeping roots, ovate, but waved and wrinkled 

 on the surface rather than striated. Leaves mostly two, crown- 

 ing the summit, three to four inches long, linear-lanceolate, ap- 

 pearing at the same time with the flowers. Peduncles slender, 

 filiform, arising from the summit of the pseudobulb from be- 

 tween the two leaves, more or less drooping, shorter than the 

 leaves, bearing about three bracteated flowers. Bracteas long 

 lanceolate, longer than club-shaped, petiolated ovary. Perianth 

 much spreading, pure- white, rather more than an inch across : 

 sepals oval-lanceolate; petals oblong-lanceolate. Up about 

 equal in length with the sepals, curved downwards, obovate, 

 three-lobed, white, with a yellow disk, and having three con- 

 spicuous lamellae or crests, waved at the margins ; side lobes ob- 

 long, plane ; middle lobe cordato-rotundate, subacute. Column 

 elongated, semiterete ; clinandrmm with a dilated margin, in 

 which the hemispherical anther-case is sunk.
