Information

Annual herb forming small woolly mats up to 150 mm across, but often much smaller, stems few to many from the crown, filiform, simple or branched, prostrate or decumbent, loosely greyish-white woolly, leafy and densely so under the heads. Leaves mostly 2,5—7 x 1—2 mm, smaller under the heads, spathulate, obtuse, base much narrowed, both surfaces loosely greyish-white woolly. Heads heterogamous, campanulate, c. 3 x 2 mm, each closely surrounded by leaves, massed in woolly glomerules c. 5—15 mm across at the branchlet tips. Involucral bracts biseriate, subequal, slightly exceeding flowers, pellu­cid, tips very obtuse, pale straw-coloured, sometimes subopaque. Receptacle shortly honeycombed. Flowers 21—35, 9—23 ("female"), 7-25 ("bisexual"), ("female") either fewer than or up to three times as many as ("bisexual"), whitish, sometimes tipped reddish. Achenes 0,75 mm, with myxogenic hairs. Pappus bristles delicately plumose from the base, the barbs shortening towards the tips, in the ("female") flowers termina­ting in a pair of cells, in the ("bisexual"), in a small tuft of clavate cells, no patent cilia at base. Fig. 2:8.
