White everlasting, Wit sewejaartjie (A)
Origin of name:
aden = a gland + karpos / carpum = a fruit / fruits
adenocarpum = glandular fruits
ammophilus = sand-loving
Basal leaf rosette
Large heads in branched inflorescence
Perennial robust herb, stock woody, crowned with 1�several leaf rosettes, flowering stems lateral, decumbent or erect, to 1 m tall, simple or forking above into a few- to many-headed very open corymb, glandular-pubescent or woolly, closely leafy. Radical leaves sub-orbicular to elliptic-oblong, prostrate, 20�40 (�140) x 15�25 (�40) mm, mostly glandular-pubescent; cauline leaves oblong to lanceolate, smaller than the radical and passing into inflorescence bracts, cobwebby or glandular-pubescent. Heads heterogamous, campanulate, 15�20 mm long, c. 25�35 mm across the radiating bracts. Involucral bracts in 9�11 series, graded, loosely imbricate, much exceeding the flowers, glossy, acute, pure white. Flowers c. 165�520, 20�90 female, 145�500 homogamous, yellow often tipped red. Achenes 0,75 mm long, barrel-shaped, with myxogenic duplex hairs. Pappus bristles several, barbellate to subplumose in upper part, bases nude, not cohering.
Flowering between August and April.
In sandy, poorly drained grassland, often around the edges of marshy depressions. Recorded on the Tongaland plain, from Delagoa Bay and Inhaca Island in Mozambique to Lower Tugela district in KwaZulu-Natal.
Two subspecies are recognized:
Radical leaves cobwebby or woolly, involucral bracts ranging from crimson to scarlet or pink, or these colours on white, or rarely pure white and then growing with plants with parti-coloured bracts
(a) subsp. adenocarpum
Radical leaves glandular, very rarely cobwebby or woolly, involucral bracts always pure white
(b) subsp. ammophilum
subsp. ammophilum generally is a much more robust plant than subsp. adenocarpum with stems sometimes attaining a height of 1 m, many-headed corymbs, pure white involucral bracts, and at least the radical leaves without wool at maturity.
