LEGUMINIFERZ. 43 
the tube, triangular-subulate, the 4 upper nearly equal, shorter 
than the calyx-tube, the lower one longer than the tube; all 
increasing in size and becoming rigid, spreading and somewhat 
leaflike in fruit, 3-nerved, with the central nerve very thick. 
Corolla twice as long as the calyx. Plant pubescent. 
In grassy places by the sea and near brackish water, and in 
salt marshes. Rare, and confined to the South of England. I 
have seen it myself only in Kent and Essex, but have specimens 
from Gloucestershire. It is also reported, on good authority, from 
Somerset, Dorset, Suffolk, Norfolk, and Monmouth. 
England. Annual. Summer. 
Stems rather rigid, nearly straight, obliquely ascending, or in 
tall specimens decumbent, 6 to 18 inches long, repeatedly branched. 
Leaflets 4 to 2 inch long, widening towards the apex. Stipules $ 
to 2 inch long, the free portion being about half this length, not 
applied to the petiole. Heads } inch long, in fruit $inch. Flowers 
pale flesh-colour, 3 to 4 inch long. Calyx-tube becoming bell- 
shaped, cylindrical and coriaceous in fruit, with 10 strongly-marked 
ribs; teeth then becoming spreading, herbaceous, with rigid nerves 
which run out into almost spiny points. Pod 2-valved. Seeds 
ovoid, smooth. Plant dull-green, pubescent, with distant short 
hairs, or more rarely sub-glabrous. 
Teasel-headed Trefoil.

SPECIES VI.—TRIFOLIUM STELLATUM. Linn. 
Puate CCCLI. 
Rootstock none. Stems few, erect or ascending, simple. Leaflets 
wedge-shaped or inversely-deltoid-obovate, obcordate, denticulate 
at the apical margin. Stipules sub-membranous, with numerous 
herbaceous branching nerves which do not anastomose, adnate 
for half their length, with the free portion large, broadly-ovate, 
shortly-acuminate, often denticulate on the margins. Leaves all 
alternate. Flower-heads long-stalked, terminal, lax, sub-globose. 
Calyx-tube obconical, 10-ribbed, with long hairs, the throat having 
an elevated ring bearing long woolly hairs, which completely close 
its mouth; teeth much longer than the calyx, all nearly equal, 
subulate-filiform, erect in flower, triangular-subulate and spreading 
in fruit, 3-nerved, reticulated with long stiff hairs on the back. 
Corolla about as long as the calyx. Plant pubescent.
