Caulis spithameus ad dodrantalem, basi repens, demum erectus, 
flexuosus, rigidus, niger, crassiusculus, sublignosus, ramosus, 
ramis fastigiatis patentibus. Folia plerumque arcte imbricata, 
bifaria, disticha, patentia, nigro-viridia, rotundato-quadrata, 
denticulato-ciliata, margine inferne subintegerrimo. Sudstan- 
tia reticulata, areolis parvis, rotundatis. Perichetialia reli- 
quorum similia, sed erecta, calyci appressa. Calyx termina- 
lis, bi-trilinearis, oblongus, basi cylindracea, apice valde com- 
pressa, ore ciliato. Seta calyce triplo longior, Capsula ob- 
longa, 4-valvis, intense fusca,

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 four 
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. asplenioides.
