10 CONSPECTUS TABULARUM. 
lous within, and margined with long, golden, gland-tipped, horizontal 
cilie. Outer corona-staminea obconical, with ten narrow-triangular, 
woolly-edged lobes, approaching in pairs; inner twice as long, of 5 gla- 
brous, strap-shaped leaflets. Follicles unknown. 
A very beautiful and curious species, for which I am indebted to Mrs. 
Barber ; and, in giving it her family name, I express my gratitude to the 
donor as well as the discoverer.

[O. seapigera: collo crasso multiplici lanuginoso, axillis hirsuto- 
lanatis, foliis radicalibus numerosis linearibus acutis carnoso-coriaceis lee- 
vibus margine integerrimo, scapis erectis unifloris subnudis bractea una 
alterave prope apicem instructis, involucri squamis octo lanceolatis mar- 
ginatis, ligulis parvis subinyolutis, acheniis glabris pappo rufescente

Hazs.—Near Port Natal, Dr. Sutherland. (Herb. T. C. D.) 
Descr.—Near O. retrorsa, var. B (DC. Prod. 6, p. 479), but the 
leaves do not taper to the base, the margin is perfectly entire, the ligules 
haye involute margins, and the scapes, in our specimens at least, are 
single-flowered. The villosity on the column and in the axils is more 
hairy than woolly, of a dirty-brown colour. The pappus is copious, and 
reddish-coloured.
