Pale green when fresh. Prickles often bent down. LiNtf. 

 Plant covered with a stony crust, whence its grittiness between 

 the teeth. St. — Plant glaucous. Stem twisted spirally, its lower 

 part and branches and lower leaves frequently naked ; upper part 

 thick set with prickles. Leaves 8 to 10 in a whirl. Prickles 

 in bundles, at short distances on the upper side of the leaves, re- 

 sembling half whirls* Not so foetid as the C. vulgaris. Mr. 

 Woodw. — Whole plant with a, strong scent of garlick, green. 

 Stem branched. Leaves 8 or 10 in a whirl. Gefmen egg- 

 shaped, of a dull pale yellow. Summits dirty green. Anther 

 orange-coloured. 



Prickly Sto?tenvort. Ditches and pools, in Yorkshire, Lan-

Stems 1 to 2 feet long, floating under water, but near the suf* 

 face, covered not as the rest of this genus, with a crust, but with 

 a thin green rind. Leaves in whirls, which, towards the root, ' 

 are 2 inches and upwards from each other, towards the end from 

 1 to ~ an inch ; of the same structure with the stem, when fully 

 grown from 1 to \\ inch long. Fructifications naked, on the up- 

 per whirls ; on the divided leaves at the fork, and on the simple 

 leaves about the same distance from the base. Cal. none, not 

 even prickles as in other species. Anther always single, some- 

 times solitary, but mostly with 2 germens : generally between 

 them, but where only 1 germen, sometimes on one or the other 

 side, or above it, never below, as in the other species ; when first 

 appearing, white or straw-coloured, as it advances pale yellow, 

 becoming of a wax-like substance, when ripe of a reddish saffron 

 colour, and at last brown, for the greater part hollow within, not 

 divided into cells, but containing some pulp intermixed with very 

 tender fibres or membranes, and some mealy grains of a saffron 

 colour ; never opening spontaneously ; gradually shrivelling, 

 rotting and wasting away. Seed-vessel oval, somewhat tapering 

 towards the point ; the coat thinish, composed as it were of 5 

 segments rolled spirally round and terminating in the 5 summits. 

 Nucleus coVered with a very thin membrane, not marked with 

 spiral lines, full within of very white transparent globules, some 

 spherical, others a little compressed, destructible by pressure, not 

 wrinkled ; whether to be considered as seeds I do not deter- 

 mine. Schmid. — The anther accords with that of Ophrys and 

 Orchis. St.
