termediate rank between L. Helveticum and L. apodum. It 
is paler coloured than the former, has a coarser reticulation, 
and more spinulose margins to the leaves, which are ovate, 
broader, more acute, and the stipules remarkably acuminated; 
the spikes shorter, with longer and more spreading scales.

This differs from L. albidulum, in its laxer and more creeping 
Stems, more distant leaves, which are also rounder, paler, 
more membranaceous, less distinctly ciliated, much more 
coarsely reticulated, more pellucid, and furnished with a dis- 
tinct slender acumen. Stipules with a more aristate point, 
and smaller in proportion to the size of the leaves.

Our specimens of this plant, which sufficiently agree with the 
character given by Desvaux, are of the size and have the 
general habit of L. Helveticum. The colour is dark bluish- 
green above, pale and almost silvery beneath ; the viua 
the leaves and stipules is comparatively thick and coriaceous; 
the leaves are furnished at the base of the epper marge. with 
@ very distinct, narrow, lunate, diaphanous auricle, which * 
wholly omitted in the description of Desvaux. The stipules 
are rather obovate than oval, with a narrow white margin, 
Which is denticulated as well as the long reflexed and, stont 
diaphanous terminal pair, and have two anricles at the base, 
one very small, the other considerably lengthened. -
