but its blunt capsule will enable the botanist to separate it from 

 J. lampocarpus and acutifiorus; and, besides the diagnostic marks 

 mentioned under suj)iniis and subverticillatus, the opake chocolate- 

 coloured calyx and capsule are very constant characters. This 

 is Ilaller's 1320, which he says he received from Dillcnius as his 

 Gramen jiinceum capsulis trianguUs minimum ; so that this clears 

 up all doubt about the synonym ; and most probably the J. supinus 

 of the Flore Francaise iii. l68. The var. /3 has its little flower- 

 heads more or less foliaceous and gemmiparous, — a monstrosity 

 to which this and its near affinities are very liable. Wahlcnburg, 

 Fl. Lap. 82., suspects, erroneously, the 6gure of it in Eng. Dot. 

 t. 801. to be the acutijlorus of Ehrhart, and of the present paper. 

 The var. y, which is not uncommon, is very likely to prove a 

 species.
