152 MR. NUTTALL’S DESCRIPTIONS OF NEW 
T. *c1L1aTUM. ©. 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; capituli axillar and terminal, rounded, many-flowered, 
destitute of involucrum, but subtended by a cicatrised circle of points; the flowers attached toa 
eylindrie torus, often ending in a long subulate point beyond the capitulum ; 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 one-seeded. 
Stipules herbaceous; the leaves rather thick and strongly veined, with forked 
vessels; calyx nearly the length of the ochroleucous flower. This is again a 
PuysanTna, but without a proper involucrum. ' 
Has. Pueblo de los Angeles, Upper California. 
T. *peNuDATUM. ©. Smooth, stem erect, a little branched, lower leaves on very long petioles ; leaflets 
obcordate or oboval, minutely and sharply serrulate ; stipules membranaceous, entire and setaceously 
acuminated ; capituli axillar and terminal, rounded, many-flowered, without an involucrum, but with 
a cicatrised circle in its place, the flowers attached to a conic torus of the same structure ; Segments of 
the calyx subequal, linear-lanceolate, sharply acuminated, nearly the length of the small ochroleucous 
flower ; pod stipitate, about two-seeded. 
About a span high; a rather small annual, and very smooth in every part. 
Leaflets about three-quarters of an inch long, three to four lines wide. Flowers 
small, with the teeth of the calyx very long and conspicuous. 
Has. With the above, which it much resembles, but the vexillum is not 
unusually inflated. 
T. *DIVERSIFOLIUM. ©. Small and smooth, branching from the base; leaflets linear or oblong, obtuse, 
perfectly entire, or repandly and rather sharply serrulate towards the apex; stipules nearly entire, 
with subulate points; peduncles longer than the leaves ; heads very small, eight to ten-flowered ; 
involucrum six to eight-parted, the divisions entire, ovate, obtuse ; calyx nearly half the length of the 
short flowers, the teeth simple and acute ; legume two-seeded. 
Remarkable for the diversity of its foliage, some of the leaflets being linear and 
quite entire, others with the same slightly serrulate; in other plants they are 
cuneate-oblong, and even emarginate. The plant about a span high, with reddish 
flowers and a deep purple tipped carina. 
Has. Near St. Simeon, Upper California. 
ASTRAGALUS. 
A. §. microLoprum. Annual or perennial? Flowers various, 
Legume small, 
scarcely exserted beyond the calyx, one-seeded, 
A .*CATALINENSIS. ©. Nearly erect and much branched ; stipules ovate, distinct, leaflets linear, deeply 
emarginate, five to seven pair, as well as the stem, scattered with appressed hairs 
in capitate heads; segments of the calyx subulate, obtuse, 
hairs, the segments all inclined to the lower side ; legume 
3 flowers ochroleucous, 
thickly clad with rough white and black 
searcely exserted, scabrous.
