XXIII. LEONOTIS, R. Br. 
Calyx tubular, 10-nerved, incurved at the apex, more or less 
oblique at the mouth, usually 8—10-toothed ; teeth often rigid and 
spinescent, rarely unarmed or obtuse, more or less unequal, the 
uppermost usually much longer and broader than the others, some- 
times all but the uppermost minute or obsolete. Corolla-tube 
usually exserted, cylindric or slightly enlarged above, naked or 
imperfectly annular-pilose inside; limb 2-lipped ; upper lip erect, 
elongated, concave, densely villous; lower lip short, spreading, 
3-lobed, marcescent ; median lobe scarcely larger than the lateral. 
Stamens 4, didynamous, ascending under the upper lip, the lower 
pair longer than the upper ; anthers approximate in pairs, 2-celled ; 
cells divaricate, subconfiuent. Disk equal. Style subulate at the 
apex, 2-lobed; upper lobe very short. Nutlets ovoid-triquetrous, 
obtuse or truncate at the apex, glabrous. 
Herbs or shrubs; leaves often ovate, sometimes oblong-lanceolate, toothed, 
usually petiolate ; floral leaves similar but smaller and often sessile ; whorls 
axillary, densely many-flowered, usually few or solitary near the ends of the 
stem or branches ; bracteoles numerous, subulate to narrowly lanceolate, often 
spinescent ; flowers sessile to shortly pedicellate, often deep orange-yellow or red, 
sometimes white, usually large. 
Distris. Species 32, nearly all in Tropical or South Africa, 1 extending into 
Tropical Asia and America. 
LL. nepetefolia, R. Br., does not appear to be South African, though Bentham 
(Lab. 618, and in DC. Prodr. xii. 535) cites a specimen collected by Forbes at 
Delagoa Bay under this name. The specimen, however, is not in the Kew 
Herbarium.
