This splendid species is growing admirably in the palm-house at Kew. It appears to 

 have flowered at Calcutta in 1861, thirty years after it had been originally introduced ; 

 and Dr. Anderson states that the specimen, although weakened, remained alive. It 

 appears to me that the seed in this species is really enveloped in a porigynium, but that 

 in the fertile flower this often becomes detached at the base, and shrinks up, forming a 

 somewhat rugose hirsute crown to the fruit, and thus the scutellum becomes exposed to 

 view ; and I believe that the false squamulaj seen in one or t^vo species are only the 

 remains of the lower part of the jierigynium.

 This is principally to be distinguished from D. IlamiUoitii by the tapering polished 



spiculaj and smooth general rhachis.
