This is one of the single-flowered species of Bulbophyllum 

 -with large usually spreading petals, to which Lindley gave the 

 same Sarcopodium, and in which the peduncle of flower is 

 really an elongated pedicel, starting from the rhizome at the 

 base of the pseudobulb, the true peduncle being suppressed. 

 Lindley 's' figure of it in the Botanical Register represents 

 the lateral sepals as of the same uniform dull blue-purple 

 colour as the dorsal and petals ; the fact is that the flower? 

 change colour after expansion, being first of a vinous red 

 but the dorsal sepal and petals becoming dull blue-purple 

 with broad spots of a dark blue, and the lateral sepals 

 yellowish speckled with bright red on the outer half. 

 Lindley figures the foot of the column as not produced 

 beyond the insertion of the lateral sepals, and so I have 

 described it in the Flora of British India, but in the 

 specimen here figured it is produced into a distinct stipes 

 to the lip. 



The fertilization of B. macranthum is the subject of a 



very interesting paper by Mr. H. N. Ridley, M.A., F.L.S., 



Superintendent of the Botanical Gardens, Singapore, 



published in the Annals of Botany cited above, and which 



December 1st. 1891.
