white, in dense subglobose clusters, from very short and thick spurs or
axillary branches.
7. C. oliganthus (Nutt, mss.): “ stem and branches villous; leaves elliptical
ovate, nearly glabrous above, villous beneath, glandularly serrulate, rather
obtuse; panicles lateral and terminal, very short, few-flowered, naked, or
leafy towards the base, persistent; disk pentangular; ovary with 3 protuberances

serrate, glabrous or slightly hairy above, canescent beneath and minutely
pubescent on the veins; flowers in ovate or oblong very dense clusters,
on long morrT or less leafy axillary and terminal peduncles.—Eschs. in
mem. acad. St. Petersb. (1826); Hook. Jl. Bor.-Am. 1. p. 125; Hook. §
Am. inbot. Beechey, p. 136.
Monterey, Upper California, Eschscholtz, Douglas ! Nuttall ! North
West Coast, Menzies.—A small tree, with a stem sometimes as thick as a
man’s arm: branches strongly angular. Leaves 12-15 lines long,' 4-6 lines
wide, narrowed at the base; petioles about 2 lines long. Clusters 1-2 inches
long ; the flower-buds at first surrounded by numerous ovate woolly bracts,

minute, obovate, rigid, fascicled, glabrous above, strigose below, entire or

1—2 inches long. Flowers white.
11. C. serpyllifolius (Nutt.): decumbent, diffusely branched; branches
filiform; leaves very small, ovate-elliptical, serrulate, obtuse, the lower surface,
as well as the petioles, strigose ; peduncles axillary ; flowers few, in a
simple corymbose head.—Nutt.! gen. 1 .p. 154; DC.prodr. 2. p. 32.
Near St. Mary’s, Georgia, B a ldw in!—A very small slender species.
Leaves 3-5 lines long; the upper surface nearly glabrous; the early ones
somewhat crowded; later ones rather distant. Peduncles 1-1J inch long,
12-15-flowered. Flowers white. 12
12. C. divaricatus (Nutt. ! mss.): “ somewhat thorny, nearly glabrous;
leaves elliptical-oblong or oblong-ovate, lucid, somewhat obtuse, minutely
and glandularly serrulate, pubescent (particularly on the nerves) beneath ;
flowering branches divaricate; leafy thyrsus interrupted; rather loose; ovary
subglobose, without protuberances.
“ Mountains of St. Barbara, California, and also near the town. April.—
A straggling shrub. The abortive branchlets at length become spinose.
Leaves 8-12 lines long, somewhat coriaceous, 3-nerved from the base, the
lateral nerves obscure: petioles about 2 lines long. Thyrsus oblong, with
several remote fascicles in the axils of the leaves. Flowers blue. Fruit
about the size of a peper-corn.” Nuttall.
* * Leaves l-rihbed, pinnalely veined.
13. C. spinosus (Nutt.! mss.) : “ glabrous ^branches thorny ; leaves cune-
ate-oblong, or oblong, obtuse or emarginate, lucid, entire, or obscurely glandularly
serrulate towards the apex; flowering branchlets divaricate, leafy;
thyrsus oblong; ovary subglobose, without protuberances.
Mountains of St. Barbara.—A straggling shrub. Leaves somewhat coriaceous,
obscurely veined, pubescent beneath in the young state, 8-10 lines
long. Flowers white or blue: pedicels 2-3 lines long.” Nuttall.—Nearly
allied to the preceding species. There is a pair of obscure nerves from the
base of the leaf; but they are scarcely as large as the veins which proceed
from each side of the midrib.
14. C. cuneatus (Nutt.! mss.): “ branchlets pubescent; leaves fascicled
from numerous very short lateral branches, and apparently opposite, thick
and coriaceous, narrowly oblong-cuneiform, entire, obtuse, glabrous above,
whitish and minutely tomentose-canescenl beneath ; flowers in lateral
pedunculate nearly simple umbels; fruit with 3 projecting appendages at the

Dry gravelly islands and bars of the Wahlamet above the Falls, Nu tta ll!
Douglas. California, Beechey. March.—A A .cb 6-16 feet high, with
somewhat thorny grayish terete branches, very closely interwoven, sometimes
forming thickets. Leaves half an inch or more in length, and about 2 lines
wide, very rarely with one or two teeth near the extremity ; the numerous
regular simple and oblique veins rather conspicuous on the lower surface.
Flowers in small axillary umbels : the peduncles and pedicels increasing in
length as the fruit ripens. Calyx and corolla wh ite: petals cucullate, un-
guiculate. Styles united above the middle, and then spreading. Fruit as
large as an ordinary pea, subglobose ; the exocarp somewhat pulpy, with 3
rather soft horn-like projections from the summit of the angles: the coherent
base of the calyx unusually large. Seeds even on both sides, black, polished.
•—-The whole plant (like several succeeding species) exhales a balsamic odor,
and the mature fruit is covered with a bitter varnish. Hooker describes the
branches as ferrugineous, which is not the case in our specimens: they are
so, however, in the C. macrocarpus, which, judging from our specimen, we
were certainly inclined to unite with the present species; but Mr. Nuttall
assures us that it is perfectly distinct.
15. C. macrocarpus (Nutt.! mss.) : “branchlets canescent with a rusty-colored
pubescence; leaves alternate, rather crowded, sometimes a little fascicled
in the axils, thick and coriaceous, obovate-cuneate, entire, often emarginate
glabrous above, whitish and minutely tomentose-canescent beneath ; flowers
in lateral pedunculate nearly simple umbels; fruit very large, with three projecting
horn-like appendages at the summit.”
Mountains of St. Barbara, California, Nuttall!—A shrub 3-6 feet high.
Fruit twice or thrice as large as in the preceding.
16. C. verrucosus (Nutt.! mss.): “branches verrucose, and (as also the
viens of the lower surface of the leaves) somewhat canescent with a rusty
