3. ce eat pliozygum Bitter, 
the more numerous specimens Me me, I think that 
the varieties proposed by Bitter are of little value. Bitter cited 
altogether only three specimens. The type of the first variety 
was a cultivated specimen raised from seeds of Uhde’s collection, 
probably from the very type collection of S. cardiophyllum. 
Schmuz 670 was also cited, with the remark that it verges 
towards the var. pliozygum. The only specimen cited under 
the second variety is Pringle 6421. The specimen of this number 
in the Columbia University herbarium has only 2 or 3 pairs of 
leaf-segments, and does in no way differ essentially from the 
other specimens.

There is one collection from Cicticarn: Rose & Rose 11183 
(represented in the U. S. Nat. Herb. and herbarium N. Y. Bot.

and the leaves decidedly pubescent beneath. Thi repre 
sent a distinct species closely related to S. phase Sbbaek 
more material is needed.
