Cacalia. | COMPOSIT (Harv.) 315 
Style-branches in the perfect fl. elongate, downy at back, produced at the 
apex into a long, every where hispid, scarcely acute appendix. Achenes 
angular, beakless, glabrescent, ciliate at the angles, the central ones often 
abortive. Pappus multiseriate, bristle-shaped, scarcely rough. DC. 
Prodr. 6, p. 336. 
A single species. The name is compounded of Aogos, aecrest, and xAawa, a cloak; 
alluding to the involucre. 
1. L, Dregeana (DC. in Deless. Ic. 4. t. 59); DO. le. 
Has. Omsamculo and Omtenda, Drege! (Herb. D., Hk., Sd.) 
A robust, glabrous, erect undershrub. Leaves 1~3 inches long, $-3 inch wide, 
alternate, sessile, half-clasping, oblong, obtuse, rigid, quite entire, 3-nerved, the 
upper narrower and more lanceolate. Branches leafy to the summit. Heads sub- 
corymbose. Fl. seemingly yellow. A very remarkable plant. 
CXII. CACALIA, Linn. 
Heads several-fl., homogamous; all the fl. tubular, 5-fid, perfect. Znv. 
uniseriate, of 5—30-scales, with a very few bracteoles at base. Recept. 
without palez. Style-branches tipped with a short cone, hispid at base. 
Achenes oblong, beakless, glabrous. Pappus uniseriate, of many rigid, 
scabrous bristles. DC. Prodr. 6, p. 327. 
Perennial herbs. Leaves alternate, mostly petiolate, toothed or lobed. Heads 
panicled or corymbose. Cor. white, rosy or yellow-white. The species are chiefly 
American and Asiatic; very few African, and only one from the Cape. Name 
used by Dioscorides for some similar plant. 
1. C.? cissampelina (DC. 1. c. 331); suffruticose, scandent, cobwebby, 
becoming glabrous; branches striate; leaves petiolate, bluntly 3~5-angled, 
5-7 nerved and netted-veined, the angles mucronate; pedunc. axillary, 
shorter than the leaf, corymbose or subumbellate, several-headed ; heads 
shortly pedicellate, g—10-fl.; inv. scarcely calycled, of 6-8 scales much 
shorter than the flowers ; corollas campanulate, with long, revolute lobes ; 
anthers much exserted. 
Han. Ceded Territory, Ecklon! Katherg, H. Hutton! (Herb. Sd., D., Cap.) 
With the habit of a scandent Senecio, but cobwebby. Petiole 14-2in. long. Leaf 
2-24 in. long and broad, pentagonal, rhomboid, or deltoid. Flowers pale. Corymb 
few or many headed, simple or branched. Scarcely generically separable from Senecio. 
CXII. KLEINIA, Linn. 
Heads many-fi., discoid, almost always homogamons, (in 1-2 sp. hetero- 
gamous), allthefl. tubular, 5-toothed. Recept. flat, naked. Znv. uniseriate, 
many-leaved, with a few small bracteoles at base, rarely nude. Style- 
branches tipped with a short cone, ciliate at base. Achenes beakless. 
Pappus bristle-shaped, roughish, in many rows. DC. Prodr. 6, p. 336. 
Fleshy, A fricanshrubs or herbs, sometimesnearly stemless, often glaucous. Branches 
terete or angular. Leaves alternate, mostly quite entire. Flowers white or pale-yellow. 
Name, in honour of J. Th. Klein, a German zoologist. Better known by a peculiar 
habit than by differential characters. It differs from Cacalia by the more copious 
pappus ; from Senecio by the conical tips of the style-branches, the constantly discoid 
heads, and white or very pale flowers. Several species unknown to me are given on 
the authority of De Candolle. They are difficult to discriminate in a dried state, 
and I fear have been needlessly multiplied.
