Anderbergia rooibergensis B.Nord.

A rather compact, much-branched, erect shrub up to 0.8 m tall, with numerous densely leafy brachyblasts and closely leafy flowering branches. Leaves suberect to erecto-patent, oblong, c. 5 mm long and 1.5-2 mm wide, greyish-tomentose, with distinctly revolute margins and an elevated midrib on lower side, apically obtuse and apiculate. Capitulescence rather loose with distinct branches, 2-5 cm in diam., consisting of several corymbiform capitula clusters. Capitulum 5-5.5 mm long, 2-3 mm wide. Outer involucral bracts 6-9, filiform-linear to narrowly oblong-oblanceolate, 2.5-4 mm long, greyish-white sericeous with long glossy hairs, membranous, brown or dark brown throughout or partially (distally), acute to obtuse (often 1-2 spatulate to subunguiculate, intermediary to inner bracts). Inner involucral bracts (8-)9, unguiculate; claw narrow, linear to narrowly oblong, white-tomentose; apical petaloid portion broadly oblong to elliptic-oblong or subsquare, 1.5 mm long, 1.2-1.5 mm wide, rounded-truncate or slightly emarginate. Female floret 1; corolla tubular, somewhat widening above, c. 2.5 mm long, white, apically glandular and shortly 5-lobed. Style branches up to 1 mm long, much exserted. Cypsela ellipsoid-oblong, 1.6-1.8 mm long, 0.6-0.7 mm wide, terete but faintly ribbed, brownish, shortly hirsute with obtuse duplex hairs and a few longer thinner setae. Ovary wall crystals largely homomorphic, acutely hexagonal, flat. Pappus bristles finely and acutely barbellate, basally barely connate or discrete, apical teeth more white and opaque. Male florets 4-5. Corolla white, 3-3.5 mm long, tubular below, narrowly campanulate above, apically 5-lobed and glandular. Anthers c. 1 mm long incl. triangular-ovate obtuse apical appendage; filament collar long and narrow; anther tails long (at least equalling collar), branching. Style base swollen, placed on a distinct stylophore, simple with subclavate truncate tip; sweeping-hairs papilliform, rounded-obtuse. Pappus bristles finely barbellate throughout with apical teeth short, densely set, obtuse and opaque.
