Dimorphotheca. | COMPOSITZ (Harv.) 421 
leafy crown, with much narrower leaves and longer peduncles. The pubescence 
varies in amount ; the marginal teeth when present are always sharp and patent. 
I find intermediate states connecting the typical D. Tragus with “ D. scabra,” DC. 
Calendula scabra, Hb. Th. partly belongs to this species ; partly to D, annua? 
8. D. Dregei (DC. 1. ¢. 72); “stem shrubby, erect, branched, the 
branches and leaves rough with glandular [scabrous] pubescence ; leaves 
crowded, sessile, linear-elongate, with 2-3 obtuse teeth on each side, 
sinuate-dentate, with subreflexed margin; pedune. naked, one-headed ; 
invol. scales 10-13, linear-lanceolate, acuminate, on the back glandular ; 
achenes of ray oblong, sub-trigonous, muricato-tubercular, of the dise 
sterile, smooth.” DC. 1. c. 
Has. Zeederberg, Drege. 
‘*A shrublet 4-5 inches high. Leaves 13~2 inches long, 1-14 line wide. Fl. 
unknown.” DC. Only known to me by a frustule, without flowers, in Hb. Sond. 
It may be a mere var. of D. Tragus. 
9. D. leptocarpa (DC. 1. c. 72); “stem subherbaceous, branched, 
glabrous [scaberulous] ; branches glandularly-pubescent, naked at the 
summit, one-headed ; leaves oblong-cuneate, toothed, glandularly-pu- 
berulent, the upper linear, entire; achenes of the ray slender, subtrigon- 
ous, along the angles and at apex sparingly tuberculate.” DC. 1. ¢. 
Has. Between Kaus and the Gariep, Drege. (Herb. Sond.) 
Leaves 1-2 inches long, tapering at base, the smaller often spathulate. Pedunc. 
2-3 inches long. Rays uncial, white, with blueish tips (‘‘ sub-ccerulescent,” DC.) 
Only known to me by a very imperfect specimen. 
B. Rays yellow ov orange. (Sp. 10-20.) 
10. D. Zeyheri (Sond.); stems short, tufted, simple, scaberulous, 
ending in naked peduncles; leaves linear-lanceolate or linear, either 
entire or coarsely few-toothed, or sinuate, subglabrous, calloso-ciliolate, 
thickish, one-nerved; inv. scales lanceolate-acuminate, dorsally scabrous, 
with white margins; rays yellow; achenes of ray triquetrous, the angles 
crenate-toothed, the faces rugulose and gland-dotted ; of dise flat, with 
wide, thickened rim, occasionally 3-winged.

971. (Herb. Sond., D.) 
Stems in dense tufts, 1-2 inches long, leafy, prolonged 4-5 inches into a sparsely 
leafy flowering stem, ending in a naked, scabrous, one-headed peduncle. Leaves 
1}-2 inches long, 2-4 lines wide, the surface mostly glabrous. Heads of small size ; 
rays scarcely uncial. Mr. Cooper's plant is smaller, less scabrous, with more entire 
leaves. 
11. D. aurantiaca (DC.! 1. c. 72); stem suffruticose or fruticose, 
erect, glabrous, pale; branches rodlike, sparingly leafy, ending in short 
pedunc., pubescent beneath the fl. head; leaves linear-oblong or spathu- 
late, obtuse, entire, narrowed at base, thick, faintly ribbed, the young 
ones minutely softly ciliolate; inv. scales linear-acuminate, longer than 
the dise, with a dorsal line of short hairs, and wide, pale margins; rays 
orange-yellow; achenes....% Calendula flaccida, Vent. Malm. t. 20.
