species of the group, Jonesianum differs in the simple 

 raceme, which ascends from the pendulous peduncle, in the 

 rise and colouring of the flower, and in the broad 

 white undivided midlobe of the lip. There i . 

 another and more dissimilar departure from the above type 

 in the 0. stipe, if Keichenbach, which is singular in 



its cylindric pseudobulbs, short raceme, arched dorsal 

 sepal, and its beaked (proboscoid) anther. This last and 

 O'J ^ire outlying species, the former inhabiting 



Minae Geras in Brazil, and our plant Paraguay, both far 

 beyond the geographical limits of the other species of the 

 group. 



0. Jonesianum was introduced by Messrs, Fred. Hors- 

 man and Co., of Stockwell Street; and I Dame of 



Mr. Morgan Jones, an enthusiastic lover of orchids. It 

 is, however, stated in " Lindenia " that it had been 

 previously brought to England by a travelling collector, 

 Louis de St. Leger, and sold at S *s auction rooms as 



0. Cebolleta. Sanders, in his splendid work, " Reichen- 

 bachia,'.' states that specimens brought by M. St. Leger in 

 1883 flowered in England four or ii\ a ago. In the 



same work Reichenbach describes and figures a remarkable 

 variety (phceanthur,,) with red-brown unspotted sepals and 

 petals, and a smaller callus on the lip. Our specimen 

 flowered in the intermediate Orchid house of the Roval 

 Gardens towards the end of September last.— J. I). II.
