PLATE 365 
Denekia oapensis, Thb, (Fl. Cap. Vol. 3, p. 119). 
Natural Order, Composites. 
Root perennial. Stems several, erect or ascending, 10 to 18 inches long, 
branching near apex, thinly woolly. Leaves, radical and lower ones linear-oblong, 
acute at apex, gradually tapering to a deeply channelled petiole, the lamina decur- 
rent as a very narrow wing almost to base of the petiole ; margin finely and 
distantly toothed in the upper portion, midrib broad and thick ; the whole leaf 
subglabrous above, densely white woolly beneath; 4 to 10 inches long, -| to 1^ 
wide in the widest part ; cauline leaves amplexicaul, lowest linear-oblong, upper 
ones becoming shorter, broader and subauricled at base, the uppermost scarcely ^ 
inch long, undulate at margins, the marginal teeth closer and longer than in the 
lower and radical leaves, like them white woolly beneath, but more pubescent on 
upper surface. Heads cymosely clustered at ends of the branches ; flowers white. 
Receptacle naked, flat. Involucre campanulate, the scales in 2 rows, those of the 
outer row oblong, glandular-pubescent, of the inner row more membranous, 
glabrous on the surface, ciliate especially towards the apex ; marginal florets in 
several rows, female, minutely glandular, their corollas bdabiate, the lobes ovate, 
equal , pappus none ; disk florets hermaphrodite (but sterile) funnel-shaped 5-fid, 
teeth acute ; glandular ; pappus of a single scale which is palmato-fimbriate at 
apex. Styles of disk-florets bifid, the branches flattened, acute ; of ray florets 
more slender, the branches terete. Achenes pubescent.

Drawn and described from specimens gathered near Durban, July, 1904. 
This genus contains 2 species only, both of which are confined to South 
Africa ; they are found in damp soil, and the above described species is common in 
such places all over the Colony ; it is an insignificant plant, and is not applied to 
any useful purpose. The pappus of the disk florets consisting of a single multifid 
scale to each is worthy of notice. In the Flora Capensis it is stated that the 
pappus consists of this scale, " and of a few small simple scales," but these in the 
specimens examined we are unable to find. The other species, D. gJabrnta, DC, 
is similar to the one here described, except that it is glabrous, not pubescent, and 
is most likely a mere variety.
