Of this species Kew possesses drawings of specimens lent by Berlin 



in 1905, from which the plate was prepared, which, however, is rather 

 deficient in details. It is desirable that Dr. Huber should at an early 

 date publish his promised account of the species of Sapium inhabiting 

 the Amazouas. Awaiting that, I may refer readers interred from 

 an economic standpoint to his paper : Arvores de borracha e de balata 

 da regiao Amazonica, i. Especies do gcnero Sapium (Tapurii, XJmrupita, 

 Curupita, Seringarana) in theBoletim do Museu Goeidi, voL iv. (1904), 

 which is a discussion on the application of these vernacular names. 

 Ule in the publication cited above gives no very definite particulars 

 of the yield of rubber of this and his S. eglandulosum ; but he suggests 

 relationship with *S. frunijoUum^ Klot^sch, a representation ol the 

 type of which appears in t. 2900,— W. Bomxa Hemsley.
