Origin of name:

pumilio = dwarf, pygmy, close growing, short
fleckii = after E. Fleck geologists who worked in Namibia during 1888-1891.

Diagnostic characters:

Compact herbs
Solitary heads
Bracts red-pink in lower half, opaque pink to white in upper half

Description:

Closely branched rounded dwarf shrublet c. 20-200 mm high or sometimes lax and open, taproot thick, woody, main stem gnarled, short, eventually up to 20 mm diam., branches erect or spreading, grey-woolly, densely leafy or sometimes more distantly so. Leaves mostly 4-20 x 1-4 mm, linear-spathulate, apex subacute, apiculate, base narrowed, petiole-like, very shortly decurrent, margins subrevolute, both surfaces generally thinly grey-woolly. Heads heterogamous, campanulate, c. 5-7 mm, sessile, solitary and terminal, often overtopped by younger growth, or solitary on dwarf lateral branchlets, or leaf-opposed and crowded at branchlet tips, or in small terminal corymbose clusters. Involucral bracts in c. 5 series, graded, loosely imbricate, inner about equaling flowers, outermost webbed to surrounding leaves, all semipellucid, white and rose, crimson or almost scarlet, the rosy tinge sometimes rather pale, very acute to acuminate or rarely more abruptly contracted to an acute tip, somewhat squarrose. Receptacle nearly smooth. Flowers 30-96, 6-30 (-51) female, 25-84 homogamous, yellow, sometimes tipped pink. Achenes 0.75 mm, with myxogenic duplex hairs. Pappus bristles many, equaling corolla, scabridulous, bases cohering lightly by patent cilia.

Flowers mainly between July and December.

Distribution:

Grows in rocky or gravelly places, often in clefts in rocks, mainly on mica schist, quartz and granite. Subsp. fleckii has been recorded only in the highlands of Namibia, from the Waterberg and Brandberg, the mountains about Windhoek, the Khomas Hochland, the Gamsberg and Naukluft mountains, south to the heights near Aus and the Little and Great Karasberge.

Nama Karoo and Desert Biomes.

Notes:

Can be confused with H. cerastioides, particularly var. aurosicum.

Two subspecies are recognized:

(a) subsp. pumilio
(b) subsp. fleckii

Differs from the typical plant principally by its white and rose, crimson or almost scarlet involucral bracts, the rosy tinge sometimes rather pale. In the southernmost part of the range, some specimens are not or scarcely to be distinguished from typical H. pumilio. Heads range from c. 5-7 mm long; leaves are generally thinly grey-woolly, but there appear to be either local races or sporadic occurrences of plants distinguished by absence of wool (H. viscidissimum) or by the possession of very densely woolly leaves (H. dinteri), or older leaves can be green and glandular, young leaves grey-woolly on the same plant; phenomena all paralleled in several other species of Helichrysum.
