Pelargonium callosum

stems short, herbaceous; radical and lower leaves tripinnately-decompound, the segments not decurrent, very narrow, sparsely pubescent, filiform, elongate; stipules ovate, acute, scabrous; sepals lanceolate, reflexed, half as long as the thickish, narrow-obovate, dull-coloured petals. Very like P. flavum and perhaps a mere variety, with less finely divided and much more glabrous leaves. The flowers are deeply yellow, with dark brown centres and evening-scented. Peduncles long, patently pubescent; the umbel many-rayed, with ovato-lanceolate bracts. Meyer's “ P. Callosum ” is more glabrous, with longer ultimate leaf-segments, but otherwise very similar: and “ P. peucedanifolium, E. & Z.! ” from Tulbaghsberg, judging from a miserably imperfect specimen in Hb. Sond. is not different.
