Leaves opposite, bases connate, crowded at base, blade c. 6-28 x 2.5-16 mm, oblanceolate, elliptic or ovate tapering to a flat petiolar part roughly length of blade, apex obtuse, margins subentire to serrate, both surfaces glandular-puberulous, hairs up to c. 0.3-0.4 mm long, occasional balloon-tipped hairs also present. Flowers many in long terminal racemes or narrow thyrses, either solitary or in 24-flowered cymules, solitary flowers and cymules often occurring together in one inflorescence. Bracts (lowermost) 1-3 x 0.5-0.8 mm, linear-lanceolate. Pedicels or peduncles (lowermost) c. 2.5-9 mm long, shorter upwards but all flowers with noticeable pedicels. Calyx obscurely bilabiate, tube 0.4-0.5 mm long, anticous lobes 2-2.6 x 0.6 mm, posticous lobes 1.75-2.5 x 0.5-0.6 mm, all lobes oblong-lanceolate, tips sometimes subspathulate, margins glandular-puberulous, hairs up to 0.1-0.2 mm long, sessile glistening glands as well. Corolla tube 3.5-4.5 x 0.75-1.1 mm in throat, cylindric, inflated near apex, limb ± bilabiate, 4.5-7 mm across lateral lobes, posticous lobes 1.5-2.2 x 1.75-2.2 mm, anticous lobe 1.75-2.8 x 1.3-2.1 mm, all lobes subrotund to elliptic-oblong, with rounded tips, white, yellow star-shaped patch around mouth and extending down tube, glabrous to minutely puberulous outside, glistening glands on backs of lobes, 4 longitudinal bands of clavate hairs in throat. Stamens 4, anticous anthers 0.25-0.4 mm long, just included, posticous anthers 0.6-0.8 mm long, included, posticous filaments bearded. Stigma 0.7-1.1 mm long, deeply included. Style 0.25-0.5 mm long. Ovary 1-1.2 x 0.6-0.7 mm. Capsules 3-3.5 x 1.5-2 mm. Seeds c. 0.5-0.6 x 0.3-0.4 mm, pallid. From: Hilliard, OM. 1994. The Manuleae: a tribe of Scrophulariaceae. Edinburgh University Press, Edinburgh.

Diagnostic description

Manulea minor has been much confused with M. exigua, from which it is easily distinguished by its scapose stems, much less markedly toothed leaves and glandular pubescence. Its relationship seems to lie with M. praeterita, from which it is distinguished by the longer hairs on the stems (up to 0.2-0.3 mm versus 0.1 mm) and leaves (up to c. 0.3-0.4 mm versus 0.25 mm), and the entire corolla lobes (not distinctly lobed).

Distribution

Manulea minor is known with certainty only from the Hex River valley; its occurrence at Bellville needs confirmation. From: Hilliard, OM. 1994. The Manuleae: a tribe of Scrophulariaceae. Edinburgh University Press, Edinburgh. [All rights reserved]
