Stem but little branched, without cortical cells, with many 

 unicellular bulbils. Whorls of 6-8 straight or incurved branchlets. 

 Stipulodes 8-12 long, slender, Branchlets of 4-5 joints, of which 

 &e upper 1-2 are much shorter, forming an acute point. Bract- 

 cells 6-8, whorled, spreading, acute, at all but the last joint of the 

 branchlets, longer than the nucule. Nucule oval, 10-12-striate.

 A small dark green plant 3-8 in. high

Wight, where it was discovered by Mr. A. G. More in August, 

 18 62, but owing to the Salterns being disused and nearly dry, it is, 

 we fear, lost in that locality. The Isle of Wight specimens appear 

 t0 be nearest to the var. Montaynei of Braun. L. afopecuroidm 

 occurs principally in France and* the Mediterranean district, the
