A native of Kreilis’ Country, Caffraria, where it was discovered 
by Henry Bowker, Esq. It is described by Mrs. F. W. Bar- 
ber, to whom we are indebted for seeds and dried specimens, as 
“a lovely plant,” conspicuous for its brilliant purple flowers. 
Unlike most of the species of Dimorphotheca, the ray-flowers are 
much more deeply coloured on the upper or inner surface than 
on the outer. The disk-flowers are remarkable for having co- 
rollas of two forms. Raised at Kew, where it flowered in June, 
1862. 
Descr. Stems herbaceous, slightly lignescent at base, purple 
erect or ascending, subsimple, laxly leafy. Leaves broadly lan- 
ceolate or oblong-lanceolate, four or five inches long, from half 
to three-quarters of an inch wide, the lower ones tapering greatly 
at base into a petiole, the upper sessile, all remotely denticulate 
or quite entire. The stems, foliage, peduncles and calyx are 
minutely puberulous, with spreading gland-tipped hairs. //owers 
on terminal, naked peduncles, two anda half inches across. Ray- 
florets brilliant purple above, pale mauve beneath. Dzsk-florets 
all deep purple ; the corollas of the outer ones with five, spread- 
ing, externally bearded lobes; those of the inner florets with
