- zadical leaves spathulato-lanceolate, much attenuate at base, entire or 
repand, callous pointed, cauline linear-lanceolate, sessile, thickish, mid- 
ribbed ; iny. scales about 12, lanceolate, pubescent ; achenes of ray 
oblong, bluntly trigonous, in the upper part minutely echinato-puberu- 
lent, below quite smooth, glossy, not wrinkled ; disc-fl. with glabrous,

Stems (including the peduncle) 12-15 inches high, leafy for about 2 their length. 
Radical leaves several, 2-4 inches long, cauline about 2 inches, all varying from 
2 to 4-5 lines broad, the radical broader. Heads erect, on peduncles 3-§ inches 
long. Rays white above, purple beneath, with glandularly scabrous tubes. Allied 
to D. Ecklonis in foliage ; differing in habit and in the achenes. Dr. Sutheriand’s 
mse ae so far as they go, agree with those of E. ¢ Z. on which the species is 
ounded. 
6. D. Barberie (Harv.); suffruticose, straggling, minutely glandular- 
pubescent; leaves oblongo-lanceolate, the lower ones much attenuated 
at base, upper sessile, acute or subacute, distantly calloso-denticulate 
or quite entire; pedune. elongate; inv. scales much acuminate, scaber- 
ulous, with membranous edges; disc-fl. sterile, of two forms, the outer 
open, with bearded, bluntish lobes ; the inner closed, the lobes conni- 
vent, inflated, or cap-like, glabrous; ray achenes smooth. Bot. Mag. t.

Young plants herbaceous, older weakly suffruticose, with long, diffuse, laxly leafy 
stems. Lower leaves 3-4 inches long, upper 14-2 inches, 4-6 lines wide. Pedunc. 
6-8 inches long. Fl. handsome; the rays uncial, of a deep bright purple on the 
upper surface, dull purple beneath. Disc-fl. also purple, the central ones with 
curious puffy-concave lobes bent inwards and forming together a flattened, waxy, 
§-angled table. The species is named after Mrs. F. W. Barber, to whom I am in- 
debted for seeds and dried specimens. It has been introduced to English gardens, 
but the cultivated specimens do not show the brilliant purple of the wild ones. 
7. D. Tragus (DC. 1. c. 71); suffruticose, rigid, scabrous, diffusely 
branched, the branches leafy nearly to the summit; leaves lanceolate- 
linear or lanceolate-oblong, acute or acuminate, scabrous and glandular, 
distantly spinoso-denticulate, the teeth short, subulate, spreading or 
deflexed; heads shortly pedunculate, at length cernuous, few-flowered ; 
achenes of the dise-fl. all abortive, of the ray bluntly 3-angled, the angles 
swollen at base into knobs, the sides wrinkled and pitted. Calendula

shortly tapering at base, 1-2 inches long, from 14 line to half an inch broad, thickish, 
nerved beneath. Pedunc. scarcely 2 inches long. Invol. campanulate, longer than
