Ankafana, Deans Cowan ! in Herb. Brit. Ifus. 



A stout plant 8 inches to 27 in height, covered thickly with 

 ovate acuminate leaves 1 to 2 inches long, and hardly \ an 

 inch across ; the lower ones clasp the stem, the upper ones pass 

 into almost lanceolate bracts. The raceme is 3 to 6 iuches long, 

 the flowers closely packed. The bracts in the lower part of the 

 raceme are | an inch in length, overtopping the flowers. The 

 petals and sepals form a galea, but are free ; the lip is oblong, 

 obscurely 3-lobed, crenulate, with a ridge running down the 

 middle ; the margins at the base are turned up so as to form a 

 channel to the entrance to the spur. It is 3 lines by \\ in 

 diameter. The spur is short and thick, the end very shortly 

 bifid. 



Cynobchis, Thouars (Cynosorchis). 



This genus seems quite natural if Amphorchis, Thouars, be 

 dissociated from it. It may be divided into two sections — lEu- 

 cynorchides, with large flowers with a 4-lobed lip and long spur; 

 and JParviflorts, with numerous small flowers, an almost entire 

 lip, with small lateral lobes and a short blunt spur. 



The genus appears to he exclusively Mascarene ; hesides the 

 Madagascar species, there are two Bourbon species, C. Arnot- 

 tioides, Eeichb. f, and parviflora, Eeichb. f, and one Mauritius 

 one, G. Boryana, Lindley.
