Dr. A. 13. Rendle informs me that the type of l^oureiro's Denis Irifoliata li 

 not preserved in the British ^Sluseum; ] consider tlie identity of this species 

 and Doris vliginosa Koxb. to be unquestionable, anil the earliest name is hence 

 adopted. The next older name appears to be Dalbcif/ia heterophylla Willd., ami 

 tlif X\\H- of this has been examined by Dr. H. Harms at my reijuest, who reports 

 tliat it is (juite the same as Dcrris uliginosa Roxb.

 Irijoimto : the former is a Dtillx ifiin, and is identical witli D. taiiiariiidifoUfi 

 Ixoxb. (see p. 90). Under the circumstances it would be illogical to consider 

 the first s])ecies described as the type of the genus, thus making Dnlbrrrpfi and 

 Denis synonymous, and hence the second species. Denis trifoliofa l,o\ir.. must lie 

 adopted as the generic type.

^^'ll('tller or not Denis niiediis and D. )tiiu(lorensis are distinct is dotditfiil. The 

 ty]ir of the former is a fruiting specimen, nearly glabrous in all parts, and 

 that of the latter is a flowering s]iecinien, the under surface of the leaflets and 

 the inflorescence somewhat pul)escent. The vegetative characters are very similar 

 in both, and flowering specimens from near the type locality of D. ))iic(nis (For.

 exact relation.ships between the two forms. A cotyjx' of /). mindorensis has 

 been determined by Mr. Rolfe at Kew as D. ferniyiiiea Renth., and it may be 

 the same as tlie sj)ecimen collected by Vidal and so reported by (\roii.''

This species belongs in the S I'untderris, and is a])parently closely allied to 

 D. nionliinn Jungh.. of Java, and to /). mahicrensis Prain. of the Malay Peninsula. 

 It diflers ficm both in its smaller leaflets, and from the latter, at least, also 

 in its nanower ])ods wiiicli are 5 to 8 cm long and 1.5 to 2 cm wide.
