Has. Table Mountain, Thunberg, W.H.H. &c. (common.) 8. Swellendam 
LE. d& Z. Drege! (Herb. T.C.D., Hook., Sond.) 
Stems 6-8 inches high, densely covered with leaves, and produced into a long, one 
or two-flowered, scapelike peduncle, 2 feet high or more. Leaves on long petioles, 
rigid, twice or thrice parted and variously cut. £8. is generally held for a distinct 
species ; but I find, in specimens from thé same locality, and even on the same root, 
that the leaflets vary much in the degree of incision. 
2. A. caffra (Eck. & Zey. Enum. No. 4); stemless ; leaves rigid, 
glabrescent, 5~7-lobed, the lobes biserrate ; petioles villous ; flower 
stalk one flowered, villous below, densely woolly above the involucre ; 
sepals numerous, lanceolate, nearly smooth. Harv. Thes. t. 7. A. alche- 
millefolia, LH. Mey ! in Herb. Drege. 
Has. Eastern districts and Caffraria, on grassy hills, Z. & Z. / Col. Bolton! and 
others. (Herb. T.C.D., Hook., Sond.) 
Leaves several from the woody rootstock. Petioles 3-4 inches long ; lamina sub- 
tifid. Flowers 14 inches diameter, rosy white ; sepals 12-18, sparsely silky or 
glabrescent. 
IV. KNOWLTONIA, Salish. 
Involucre none. Sepals 5, green, imbricate, deciduous. Petals 
numerous (5-15) flat, with naked claws. Carpels very numerous, capl- 
tate, one-seeded ; when ripe becoming fleshy and juicy. Style de- 
ciduous. Seed suspended, DC. Prod. 1. p. 23. 
Perennial, stemless, herbs, with radical, rigid, ternately decompound leaves ; 
branching, cymose or umbellate scapes ; and greenish or yellowish flowers. This 
genus is exclusively South African. The species are extremely acrid and the com- 
monest ( K. vesicatoria and K. rigida) are popular colonial remedies for rheumatism, 
&c. The bruised leaves, applied to the skin, raise an effective blister. Popular 
name “ Brand-Blaren,” (see Pappe’s Fl. Cap. Med. Prod. p. 1.) The generic name 
is in memory of Mr. Th. Knowlton, a meritorious cultivator, and formerly cura- 
tor of Sherard’s famous garden at Eltham. 
1. K. vesicatoria (Bot. Mag. t. 775) ; subglabrous ; leaves biternate, 
thick, segments ovate or cordate, serrulate or nearly entire, the lateral 
ones obliquely truncate at base, subsessile ; peduncles spreading, 
umbellate, the umbel compound, many rayed ; pedicels villous ; petals 
spathulate, obtuse ; ovaries glabrous, as long as the subulate style. DC. 
Prod 1. p. 23. Bot. Reg. t. 930. EH. & Z.! En. No. 8. 
Haz. Common near Capetown, and throughout the Colony ? also in Kaffirland, 
£. & Z.! &c. (Herb. T.C.D., Hook., Sond.) 
Leaves a foot or more broad ; the leaflets 3 inches long and 2 broad, often nearly 
entire. Flowers green. Berries blackish purple. The umbel, is said, by authors, 
to be unbranched and few flowered ; but it is more frequently doubly and sometimes 
trebly compound, as is well represented in the figure in Bot. Reg. t. 936. 
2. K. rigida (Salisb. Prod. 372) ; sparsely hairy ; leaves biternate, 
thick, subglabrous, segments vasa sy stint sharply serrate, the 
lateral ones obliquely truncate, or cordate at base, subsessile ; pe- 
duncles patent, umbellate, the umbel many rayed ; pedicels pubes- 
cent or villous ; petals subspathulate, obtuse ; ovaries glabrous, shorter 
than the subulate style. Box. : I
