H.AB. San Bias to Tepic.—We possess the same plant from various parts of S. America, but are by no
means certain of our correctness in referring it to the J . hirta of Vahl. The leaves vary much in different
specimens, from ovato-lanceolate to oblong-lanceolate, the hairiness is chiefly confined to the upper part of
the plant. The pods are about an inch and a half long, when ripe, destitute of the calyx-segments.

H - \ b . fi. Between San Bias and Tepic— Dr Sinclair's specimens differ in no respect from those gathered
during Captain Beechey’s former voyage, except in being more pubescent, especially in the younger parts of
the plant, and upon the flowers, and in there being rather longish spreading hairs mixed with the down upon
the calyx and pedicels.

H a b . Between San Bias and Tepic.—A very graceful plant. The leaves gradually pass upwards among
the branches into small bracteas. The hairs with whieh almost every part of the plant is clothed, except the
pedicels and flowers, are rather long and seated upon a small bulb ; those of the stem and petioles and midrib
beneath are more harsh and rigid than the rest, reflexed and very close pressed. Pedicels extremely slender,
subtended by a minute bractea.—The figure of Jacquiu above quoted is an excellent representation of a
flowering branch.

H a b . San Bias and Tepic.— W e had considered this to be a new species: but Mr Bentham has referred
specimens of the same plant in Hartweg’s Mexican collections (n. 25) to the C. Llavea, of La Liave and De
CandoUe, which latter author has thus characterized it: “ caulibus pluribus hispidulis, ramis ascendentibus,
foliis subsessilibus ovato-lanceolatis strigosis, pedicellis interfoliaceis erectis, petalis 2 obovatis magnis, cæteris
aiiortivis, stam. 11 .’’-O u r character will be seen (supra, p. 289.)—Our specimens in the present collection are
a foot and a half to two feet long, extremely rough with the copious rigid hairs or bristles, with which every
part of the plant is clothed. The specimens gathered by Dr Sinclair are rather more glaucous than our former
ones, and the large calyx does not in general exhibit so deep a tinge of purple, though that circumstance is
very variable.— Our var. fi. has some of the leaves of the stem three inches long, but the upper ones are much
reduced in size, and so imbricated as to give the appearance of a dense bracteated spike to the flowers.
2. C. floribunda, Hook, et A rn . supra, p . 289.
H a b . San Bias to Topic.—Copious specimens of this fine species are in the present collection, exhibiting
all the peculiarities we have mentioned in our specific character. It is a tall growing species. Leaves
2-3 inches long, exceedingly rough to the touch. The flowering branches often run out to a great length,
(10 inches or a foot) and bear small, distant, but opposite, narrow-lanceolate, braeteiform leaves.
3. C. bracteata. Hook, et A rn . supra, p . 2 89.—an C. bracteata ? L a g . et De Cand. 2.
H a b . San Bias and Tepic.—The C. bracteata of Lagasca is a Mexican speeies, of which the brief description
given by De Candolle tolerably accords with our piant. The stems and branches are woody and the
bark readily peels off in large flakes. The leaves are little more than half an inch long.

H a b . San Bias to Tepic.— Better specimens than we formerly possessed of this plant, enable us to give, in
the following words, its more obvious characters:—fruticosa, ramis tetragonis glabriusculis, foliis ovatis
oblique penninerviis brevi-petiolatis integerrimis pubescenti-setosis, floribus in ramis pluribus brevibus
corymbosis paniculam fonnantibus, calyce 4-fido tubo ovato lævi setis copiosis apice glandulosis tecto
lobis lanceolato-acuminatis glabris, staminibus 8, 4 majoribus basi longissime bicoruis, 4 basi paululum constrictis
appendiculis nullis, capsula glaberrima basi calyci adhærentc This plant has a woody stem, in
our present specimeus a foot and more long, with opposite square branches. Leaves, the largest of them,
scarcely an inch long, on very short petioles, ovate, acute, or rather obtuse, entire, obliquely and constantly
penniiierved, the nerves all springing from the midrib and directed upwards, above and at the margin sparingly
setose with short hairs, beneath paler coloured and the hairs chiefly confined to the costa and nerves.
The upper branches are short, and bear leafy corymbs of few, rather small-sized flowers ; the collected flowering
branches thus forming a leafy corymbose panicle. Calyx 4-cleft, the tube ovate, slightly contracted at the
mouth, even (not ribbed); clothed with spreading setæ, which are terminated with a viscid gland ; lobes of the
calyx lanceolate, acuminate, spreading, destitute of setæ. Petals 4, obovato-rotund, ciliated. Stamens 8, 4
larger of which the anthers are linear-oblong, furnished at the base with 2 long horns or fleshy setæ ; the 4
smaller ones arc destitute of those horns, and are only slightly constricted at the base so as there to form a sort
of tubercle. Ovary broadly ovate, quite glabrous, the lower half incorporated with the base of the tube of
the calyx, the rest free ; style filiform or slightly clavate. The whole plant has a blackish hue when dry.
