Leonotis ocymifolia var. raineriana
The tube of the 2-lipped corolla is more or less funnel-shaped; the upper lip is erect, elongate, concave, densely villous and fringed within; the lower lip is very short, spreading, 3-lobed with the middle lobe scarcely longer than the other two. The stamens are 4, didynamous, ascending under the upper lip, with the lower pair longer than the upper; the filaments are broadly linear; the anthers are approximate, in pairs, 2-thecous, with the thecae divaricate.
