colored pubescence; leaves alternate, approximate or crowded, very thick and
coriaceous, roundish-obovate or cuneate-oval, often emarginate, the younger
ones sometimes obscurely serrulate, glabrous above, minutely tomentose-canes-
cent beneath ; umbels axillary, few-flowered, naked ; fruit with minute protuberances
at the angles. r
“ Low hills near the coast, St. Diego, California.—Leaves about half an
inch long, and 4-5 lines wide, similar to the preceding in texture, venation
&c. Flowers white. Fruit the size of a large pea.” Nutt.—Very near C.
cuneatus /?., and perhaps only another variety of that species; from which
it differs, however, in its broader leaves and tuberculate stems, as well as in
the minute tubercles of the fruit.
. & rigidus (Nutt.! mss.) : “ young branches pubescent; leaves opposite
and crowded, cuneate-obovate, mostly retuse, thick and coriaceous, mu-
cronately crenate-toothed, glabrous above, somewhat canescent beneath *
umbels axillary and terminal, few-flowered, sessile; pedicels at length elongated
; ovary with 3 protuberances.
“ Bushy woods near Monterey, California. March—A shrub about 6 feet
high, rigid, intricately branched, almost spinose. Leaves about half an inch
long, sometimes nearly obcordate; teeth conspicuous ; the veins, &c. as in
the preceding. Clusters of flowers composed of several small crowded umbels;
the pedicels gradually elongating to the length of 3-4 lines. Calyx and
corolla bright blue.” Nuttall.—Resembles the last two species in many
respects. ;
18. C. dentatus: branches (and veins of the leaves beneath) tomentose
with rusty hairs; leaves much crowded and fascicled, coriaceous, oblong-
cuneiform, retuse, toothed, with revolute margins, more or less hairy on
both sides; peduncles elongated, nearly terminal; thyrsus oblong, of numerous
umbel-like fascicles ; ovary with three protuberances at the 'summit.
California, Douglas!—Leaves scarcely half an inch long, strongly and
remotely feather-veined, pitted beneath, irregularly and obtusely toothed.
Peduncles an inch or more in length. Flowers crowded, white.
19. C. papillosus: branches tomentose; leaves narrowly oblong, much
crowded, fascicled in the axils, densely and softly tomentose beneath, gland-
ularly denticulate on the margin ; peduncles aggregated; clusters somewhat
capitate ; ovary triangular, the angles projecting at the summit.
California, Douglas /^Branches terete. Leaves 1—14 inch long (those
fascicled in the axils smaller), fringed on the margin with numerous capitate
glandular teeth; the upper surface conspicuously papillose and somewhat
hairy. Peduncles numerous at the summit of the branches; the flower-buds
at first invested with ovate woolly bracts: pedicels 2-3 lines long. Flowers
blue.
Order XLVIII. LEGUMINOSiE. Juss.
Sepals united into a 5-cleft or 5-toothed c a ly x ; the segments often
unequal or variously combined, the odd one inferior. Petals 5 (sometimes
by abortion fewer or wanting), perigynous or hypogynous, irregular
and unequal (papilionaceous), or sometimes regular, distinct or
variously cohering; the odd petal superior. Stamens definite or indefinite,
inserted with the petals, distinct, or monadelphous, or diadel-
phous, or very rarely triadelphous : anthers versatile. Ovary simple,
solitary (very rarely 2 or more), free from the calyx : ovules solitary
or sev era l: style proceeding from the upper or ventral suture : stigma
simple. Fruit a legume, or sometimes a drupe. Seeds solitary or
several, heterotropous or anatropous, sometimes with an aril or large
caruncle : albumen none. Embryo straight, or with the radicle bent
back along the edge o f the cotyledons : cotyledons either thin and
somewhat foliaceous, or thick and fleshy.— Herbs, shrubs, or trees.
Leaves alternate, stipulate, usually compound, sometimes reduced to a
solitary leaflet: the margin o f the leaves or leaflets almost always en .
tire. Flowers axillary or terminal, solitary or commonly racemose,
paniculate, spicate, or cap ita te: pedicels usually articulated.

Sepals imbricated (or sometimes slightly valvate) in aestivation.
Corolla papilionaceous or more or less irregular, rarely wanting. Stamens
10, or occasionally fewer, inserted with the petals into the bottom
o f the calyx, or perigynous. Radicle bent back upon the edge o f
the cotyledons, or straight.— Leaves simple or simply compound (in
Cassiese sometimes bipinnate). Flowers usually perfect.
T ribe I. VICIEA3. Broun; DC.
Corolla papilionaceous. Stamens diadelphous (9 and 1). Legume
continuous (not articulated), dehiscent. Radicle inflexed. Cotyledons
thick, farinaceous, remaining under ground unchanged in germination.—
Herbs, with abruptly pinnate leaves ; the common petiole
not articulated with the stem, produced at the apex into a bristle or
tendril.

Calyx tubular, 5-cleft or 5-toothed; the two upper teeth shortest. Style
filiform, bent at a right angle with the ovary, villous at the apex, particularly
on the outside (next the keel). Legume oblong, several-seeded.—Mostly
climbing herbs. Leaflets several pairs. Petioles produced into branching
tendrils. Peduncles axillary.— Vetch.
* Peduncles elongated. ,
1. V. Americana (Muhl.) : glabrous; leaflets numerous (10-14), elliptical-
lanceolate or ovate-oblong, obtuse or retuse, mucronate ; stipules semisagit-
tate, deeply toothed; peduncles shorter than the leaves, 4-8-flowered, lower
teeth of the calyx broadly lanceolate ; style very villous at the apex ; legumes
