Nigeria : — In the valleys of the mountains north of the 

 Katsena River, North Nigeria, approx. lat. 7° N., long. 10° E. 

 Collected in 1913 and flowered in the Royal Botanic 

 Garden, Edinburgh, October 1915. The small flowers have 

 the sepals tinted a beautiful rose and are themselves in a 

 compact subglobular spike not unlike that of certain Poly- 

 gonums. The afiinity seems to be near B. I'ecurvum, Lindl. 

 (Bot, Reg. 963, under Tribrachia pendula) and near B. 

 Winkleri, Schltr. from the Cameroons. The speciflc name 

 is in honour of Miss Imogen Ramsay of Bamfl". 



The locality of Polystachya Hamiltonii, W. W. Sm. 

 (Notes R.B.G. Edin., viii (1915), 347), which was stated 

 somewhat indefinitely at the time of the description, is 

 approximately lat. 7° 25' N., long. 8° 30' E., in the valley of 

 the Benue River. This orchid has an inflorescence some- 

 what more branched and certainly with more flowers than 

 indicated in the orio-inal diacfnosis.
