Corymbium elsiae Weitz
LC Indigenous Endemic

Morphological description

Similar to C. laxum subsp. laxum, but differing by the scabridity of the corymbophore, cauline leaves and bracts. Roots wiry. Leaves glabrous; blades narrowly linear to falcate, sometimes canaliculate, (80-)12()(-170) mm long, 1.5-2 mm broad, apex acute, base dilated, clasping with submembranous margins, silky hairs prominent, margins involute, veins not prominent; texture coriaceous becoming rugulose; cauline leaves scabrid, 5-65 mm long, 1-2 mm broad, clasping or half- clasping, diminising in size upwards. Corymbophore round to angular in cross section, scabrid, glandularly muricated, (150-)190(-255) mm long, 1.5-2 mm in diameter, branching from corymbophore dichotomously. Heads distinctly pedunculate or with a very short penduncle ca. 1 mm or sessile, arranged in a panicle. Involucral bracts scabrid, glandularly muricate, 2-3 smaller bracts subtending 2 upper bracts; upper bracts (6.5-)9.5(-12) mm, apex trifid or fimbriate, purple or greenish purple. Flowers mauve, pedicel present. Petals oblong elliptic (4.8-)6.8(8.3) mm long, ca. 2 mm broad; corolla tube 3-5 mm long. Anthers ca. 4.2 mm including base. Ovary hirsute, style branches long obtuse. Cypsela ca. 5 mm long 1.5 mm broad, linear to elliptic. Pappus coroniform at base, fibriate, bristles many 1 mm long. From: Weitz, FM. 1989. A revision of the genus Corymbium L. (Asteraceae). S.

Diagnostic description

Diagnostic features: Radical leaves glabrous; blades narrowly linear to falcate, sometimes chanelled, margins involute. Corymbophore scabrid. Heads distinctly pedunculate or with a short peduncle or sessile, arranged in a panicle. Involucral bracts scabrid, trifid. Flowers mauve. Ovary hirsute. C. elsiae is closely allied to C. laxum differing in scabridity of the corymbophore, cauline leaves and bracts, and with cellulosic leaf epidemal cell walls. There is a considerable variation in the arrangement of heads in the conflorescence of C. elsiae. It is either distinctly pedunculate or with a very short peduncle or sessile. The conflorescence of certain populations may vary from a simple to a much-branched panicle with pedunculated or sessile heads. Therefore, pedunculated heads is not a constant character for this species as in C. laxum. Although local races may appear distinct, continuous variation of the corymbophore morphology within a race does not warrant the subdivision of this species into infraspecific taxa.

Habitat

Populations occur on steep rocky slopes especially in crevices, in shallow soil derived from Table Mountain Sandstone. This species usually grows in association with low-growing Restionaceous Fynbos.
