Morphological description

Moderately and often subdichotomously branched, sometimes subspinescent shrubs. Leaves flat-somewhat triquetrous, mid-ribbed, linear-narrowly elliptic-oblong, 2-10 mm long, 0.5-2.5 mm wide, tomentose and often glandular with stalked glands, greyish green. Involucre campanulate, 3-15 mm wide. Involucral bracts 25-50, outer ovate-oblong, inner gradually longer and oblong-obovate, basally firm and yellowish brown, upper displayed Part spreading, thin and papery, with a dark brown middle stripe and wide, pale, scarious margins, up to 12 mm long, up to 4 mm wide. Receptacle paleate and sometimes also shortly squamose. Paleae subtending all or occasionally only outer disc-florets, subulate-linear-narrowly spatulate and flat or oblong and canaliculate and almost embracing disc-floret basally, entire orapically irregularly serrate-laciniate, 7-12 mm long, 0.3-2 mm wide. Ray-florets 5-18. Lamina elliptic, 5.5-12 mm long. Style 5-8 mm long. Disc-florets 12-55. Corolla 4.5-6.8 mm long. Style 5.5-9 mm long. Anthers 3.3-5 mm long; tails c. 1/4 of the length the anther. Achenes terete or somewhat angular, narrowly oblong, 3.5-5.5 mm long, 0.7-1.2 mm wide, glabrous or mainly apically pilose, smooth or basally transversely rugose; pappus crownlike, of ± connate scales, up to 2 mm long, almost always also with 1-4, 4.5-7 mm long, barbellate bristles. From: Bremer, K. 1976. The genus Rosenia (Compositae). Bot. Not. 129: 97-111. [All rights reserved] As: Rosenia glandulosa Thunb.

Twiggy, rarely somewhat thorny shrublet, up to 300 mm tall. Leaves linear-oblanceolate, 2-10 mm long, grey-felted, often glandular-hairy. Flowerheads solitary at branch tips, radiate, yellow with reddish reverse, 10-20 mm diam., receptacle conspicuously paleate; involucre cup-shaped, 4-14 mm diam., bracts dark brown with broad white papery margins, inner elliptic.

Diagnostic description

This species is characterized by its involucre with thin and papery, brown and white bracts. The receptacle is generally furnished with narrow-wide paleae, whereas it is almost always epaleate in the other species. R. glandulosa is possibly most closely related to R. spinescens. Apart from the spines in the latter species, they are similar in habit and they have vicarious distributions. Starved specimens with small capitula look similar to R. oppositifolia, but they can nevertheless be distinguished by the above mentioned characters. From: Bremer, K. 1976. The genus Rosenia (Compositae). Bot. Not. 129: 97-111. [All rights reserved] As: Rosenia glandulosa Thunb.

Habitat

It grows in often stony karoo veld on lower mountain slopes. From: Bremer, K. 1976. The genus Rosenia (Compositae). Bot. Not. 129: 97-111. [All rights reserved] As: Rosenia glandulosa Thunb.

Distribution

R. glandulosa is not uncommon in the Nieuwveld and Roggeveld mountain ranges up to Calvinia and just north from there. From: Bremer, K. 1976. The genus Rosenia (Compositae). Bot. Not. 129: 97-111. [All rights reserved] As: Rosenia glandulosa Thunb.
