this plaut; but I liave only seen a single flower of it, iu the 

 British-Museum Plerbariunij not in sufficiently good condition to 

 base much upon. 



Both the other species of ^^r^wf 7^ z^s, viz. A. ffrandiflorus and 

 A, Arachiites^ were also obtained by Dr, Fox at Ambatovory. 



^ONiA EOSEA, Bidley. Ambatovory, D)\ Fox^ no. 26. Tliis 

 differed from the type in having a white lip. Some time ago I 

 was shown at Kew a coloured drawing of a similar variety.

This little plant, with its short blunt leaves and solitary flowers, 

 is remarkable for the lip being continued directly into the spur 

 without any break or bend at its junction. The long slender 

 spur, too, looks quite out of proportion to the rest of the flower. 

 Among Deans Cowan's drawings is a figure of a phmt from 

 '' trees, Ankafana," which seems identical with this species. The 

 flowers are light green.
