 Java plant is narrower, denser, and more hairy than that of the Siam plant. This 

 Java plant is written up in Herb. Kew. as Mesona sp. nov. Bentham MSS. [1879] 

 and for the moment may bear the name Nosema capitatum var.? javanica, C.B.

Noviciae Indicae XXJ. An undescrihed Indian Musa. — By D. Prain. 

 [Read 2nd December, 1903.] 



Three years ago a native collector in the service of the Royal 

 Botanic Garden, Shibpur, sent to Calcutta the rootstocks of a Musa 

 from the Jaboca Naga country. The plant has thriven well and has 

 recently flowered. As the species is very different from any Musa 

 hitherto in cultivation in the Royal Botanic Garden, is unrepresented in 

 the herbarium collections either at Kew or at Calcutta, and is undes- 

 crihed in Mr. Baker's Synopsis of the Genera and Species of Musese or in 

 Professor Schumann's article Musacese in Engler's Pftanzenreich^ a 

 formal description of the plant is herewith offered to the Society.
