Different as this species is in reality from the preceding one, . 
(J. ramosissima) yet I have found it very difficult to express this - 
difference clearly in words. The present plant is vastly more: 
stout and robust in all its parts, the stem very rigid and of a black - 
colour. The leaves larger, more horizontal in their direction, more 
inclined to quadrate, more ciliated, and altogether of a much 
darker hue. A greater point of distinction may be found in the: 
calyx, which is less urceolate, and in the capsule moreover, which 
is oblong. The vastly larger size of the plant, repeatedly branched: 
stems, the shorter fruitstalk and more ciliated leaves, are the 
principal marks which distinguish this from J. aspleniotdes.
