Botanists seem now to be agreed that the genus issolia 
should be confined to the first section of De Candolle, ‘“ Nisso- 
liaria ;? the other Species being referred to Macherium. Of 
the three species in that section, Mr. Bentham has, in my Her- 
ium, if not elsewhere, recorded his opinion that two out of 
the three constitute but one species; or, in other words, that 
N. racemosa is only a variety of the original N. fruticosa. Indeed 
I possess the two forms on a single specimen. The remaining — 
_— N. hirsuta, 1 have myself ventured to unite with it, differ- 
Ing, as it does, only in a little more hairiness.-
