but its blunt capsule will enable the botanist to separate it from 
J. lampocarpus and acutiflorus ; and, besides the diagnostic marks 
mentioned under supinus and subverticillatus, the opake chocolate- 
coloured calyx and capsule are very constant characters. This 
is Haller's 1320, which he says he received from Dillenius as his 
Gramen junceum capsulis triangulis minimum ; so that this clears 
up all doubt about the synonym; and most probably the J. supinus 
of the Flore Francaise iii. 168. The var. B hás its little flower- 
heads more or less foliaceous and gemmiparous,—a monstrosity 
to which this and its near affinities are very liable. Wahlenburg, 
Fl. Lap. 82., suspects, erroneously, the figure of it in Eng. Bot. 
t. 801. to be the acutiflorus of Ebrhart, and of the present paper. 
The var. y, which is not uncommon, is very likely to prove a
