I could not agree with Knrz {Joum. As. Soc. Beng. 1870, ii. 64, but corrected in 

 Begmsb. Flora, 1872, 189), that the foliage of Z>. cordatus, Wall, (not cordifolius, as 

 cited) is identical with that of Z>. obtusifoUus. Miquel describes the calyx-tube in fruit 

 as "exalatus;" it does not appear however that he ever saw it mature, 



+t Angles or wings prolonged to the base of the calyx-t^the or nearly so.
