J? rom Qoodyera three forms require to be distinguished. Firstly, 

 AchiUe Eichard's Platylepis, the Qoodyera occulta of Du Petit 

 -Chouars, the Kp of which has a pair of caUi within the base, and a 

 long column, the stigmatic area of which is bordered by a mem- 

 brane ; for this, of which I have a second species from Tahiti, I 



admitted 



NotiopTirm 



A second genus is the section of 



Ooodyera, which I formerly called BhampUdia (G 

 P- 494), and at a later period CerochiluSy distinguished from Oood- 

 yera by its dorsal lip with calli instead of hairs within, and from 

 Macodes and Bhomhoda by the want of appendages on the column. 

 i-he last-mentioned genus is foimded upon a most remarkable 

 plant, native of Sikkim, with a great saccate dorsal lip, a truncate 

 colunin having quite a fimnel- shaped anther-bed, and a pair of 

 large, soft, tooth-like transverse processes in front, resembling in 

 form the mandibles of a coleopterous insect, added to which the 

 customary calli within the base of the lip are so large and thin as 

 almost to deserve the name of petaloid. Of the importance 

 Signification of these processes I hope to offer some explana 



and 



on another occasion. 



The last group, in which the base of the lip is flat, consists of 

 four certain genera, Chloidia, Zeicxine, MonocUlus, and Cheiro- 

 ^tylis, to which mav possiblv be added Blume's Eucosia^ a plant

Leaves three, stalked

 blong lanceolate acuminate, "shorter than the scape, which has three close- 

 messed sheaths and is downy under the spike. Spike itself and ovaries downy, 

 inches long.— Found once only in Tahiti by Bidwill (who at first took it foi 

 Cominelyna\ on a rock, in the bed of a stream, in the valley of Fataua, about 

 iJiile beyond the native camp.
