Cult. All the species of Loàsa bear such beautiful flowers, 
that they are all worth cultivating for ornament, but they are 
so full of stings that it is impossible to handle them. The 
seeds of the annual species should be sown early in spring in 
the open ground, and the plants so raised will flower and pro- 
duce seed the same season; or the seeds may be sown in pots, and 
reared in a hot-bed, and the plants may afterwards be planted out 
in the open border, in any convenient situation. Ail the species 
require a rich light soil and a warm situation. Some of the 
species are said to be perennial; we suppose all would be so if 
they were protected from frost. 
IV. CAIO'PHORA (meaning not explained). Presl. in 
reliq. Henk. 2. p. 43. 
Lin. syst. Polydélphia, Polydndria. Calyx 5-parted; seg- 
ments jagged. Petals 5, unguiculate, concave. Scales 5, peta- 
loid, emarginate, or 4-toothed at the apex, each furnished with 
4 sterile filaments inside. Stamens numerous, disposed in 5 
bundles. Style trigonal, permanent; stigmas 3, conniving. 
Capsule ovate-oblong, with elevated spiral ribs, crowned by the 
reflexed calyx, 1-celled, many-seeded, opening at 3 of the su- 
tures. Placentas marginal in the valves, but at length distinct 
from them. Seeds angular, echinated by bristles or reticulated. 
—Usually climbing plants, with the habit of Lodsa, beset with 
stinging hairs. Peduncles 1-flowered. Flowers yellow. This 
genus differs from Lodsa and Blumenbachia in the dehiscence of 
the capsule, in the scales being furnished with 4 sterile filaments 
instead of 3, and in many other points. There are several plants 
how referred to the genus Blumenbachia which belong to this ge- 
nus; viz. B. grandiflora, which is Caiéphora contorta, Presl, reliq. 
Henk. 2. p. 42. and B. punicea, which is evidently the Caiéphora 
circiifdlia, Presl. l. c. t. 54. and carduifdlia, Presl. 1. c., p. 42. 
1 C. corona'ta (Hook. et Arn. in bot. misc. 3. p. 238.) 
stems short; leaves opposite, petiolate, pinnate; segments bi- 
pinnatifid : lobules denticulated ; peduncles axillary, 1-flowered, 
elongated ; calycine lobes pinnatifid, with linear segments, longer 
than the ovarium. ©. H. Native of Chili, on both sides of 
the Cordillera of the Andes, between Mendoza and Chili, at an 
elevation of 8500 to 11,000 feet. The furrows of the fruit arë 
nearly straight, or hardly spiral, so that this species partakes in 
some degree of the characters of Loàsa. Loàsa coronàta, Gill.

a cylindrical, somewhat 5-furrowed tube, and 5 lanceolate or 
subulate, equal lobes (f. 13. d.). Petals 5 (f. 10. a.), equal, 
inserted in the upper part of the tube of the calyx. Stamens
