8 [Feb. 



to five, united at base into a short stipe, 1-celied ; ovules many, attached to the 

 ventral suture in a single crowded series. Sliginas thick and sessile, recurved. 

 Capsules two to five, coriaceous and cylindric, opening longitudinally and in- 

 wards, many-seeded. Seed roundish-reniform, nearly surrounded by a deeply 

 fringed arillus. Embryo not seen. — A Californian shrub, with alternate, entire, 

 crowded, exstipulate leaves, and 1-flowered, short, terminal branchlets ; flowers 

 white. 



C. CaUfornica. 



Har. Abundant on the borders of streams in the island of Catalina, off 

 the coast of Upper California. Flowering in February. 



TRIFOLIUM. 



§. *Physantha.. ( Tnvolucrarium.) With the calyx 5-cleft, one or two of the di- 

 visions smaller. Corolla marcescent. The vexillum transformed into a physi- 

 form sac, which at length envelopes the very small wings and monopetalous 

 carina. Stigma capitate. Legume stipitate, 2 to 5-seeded, included in the calyx. 



T. *stmophyllain. .\nnual, branching from the base; leaves ternate, smooth 

 and linear, distantly serrulate; stipules subulate, sparingly denticulate; pe- 

 duncles elongated, filiform, heads small and nearly round, the vexillum, at length, 

 forming a membranous inflated sac of equal breadth throughout, embracing the 

 small wings and small carina, which is monopetalous, with but one broad claw 

 attached to the vexillum. 



Hab. The island of Catalina, near Santa Pedro, Upper California. 

 Flowering in February. 



T . '* G amhelii . Perennial and decumbent, smooth, branching from the base; 

 leaflets roundish-oval or cuneate-oval, obtuse, very minutely and sharply ser- 

 rulate; stipules membranaceous, dilated, entire, with subulate, slender points; 

 peduncles about the length of the leaves; involucrum about S-cleft, the seg- 

 ments lanceolate, acuminate; teeth of the calyx trifid,or simple, with setaceous 

 points; legume stipitate, 3 to .'i-seeded ; wings longer than the vexillum. 



Hab. Island of Catalina, St. Simeon and Pueblo de los Angeles. 



A large, robust species, with shortish branches, very large stipules, and 

 heads of large flowers, which appear to have been whitish, with purple tips to 

 the carina ; heads of flowers 1 to H inches across; the vexillum very wide 

 below, so as to conceal the other petals ; the wings and carina are also united ; 

 leaflets three quarters of an inch long, and about the same breadth. 



T. *cilkdum. Q. Smooth and erect, but little branched ; lower leaves on 

 very long petioles; leaflets cuneate-elliptic or oblong, obtuse, minutely and 

 sharply serrulate; bractes adnate, subciliate, herbaceous, entire and acutely 

 acuminate; capitnli axillar and terminal, rounded, many-flowered, destitute of 

 involucrum, but subtended by a cicatrised circle of points ; the flowers attached 

 to a cylindric torus, often ending in a long subulate point beyond the capitulnm ; 

 segments of the calyx unequal, one of the teeth small, the rest lanceolate, sharply 

 acuminated and bristly ciliated with stiff" hairs ; vexillum enclosing the other 

 petals, which are small; legume flat, stipitate, about 1-seeded. 



HiB. Pueblo de los Angeles, Upper California. 



Stipules herbaceous ; the leaves rather thick and strongly veined, with forked 

 vessels ; calyx nearly the length of the ochroleucous flower. This is again a 

 Physan-iiia, but without a proper involucrum.
