Gnaphalium collinum Labill.

Description

Perennial herb with creeping rhizomes or stolons bearing tufts of lvs at nodes, tufts us. close together. Stems scapiform, slender, up to 15 cm. or more long, bracts foliaceous below, rapidly reduced above. Lower lvs obovate-spathulate, petiolate, apiculate, up to 4 cm. or more long, softly woolly-hairy above (becoming glab. or nearly so), densely softly white-tomentose below, margins slightly revolute, undulate to plane. Stems slender, tomentose, with rather distant lvs, the upper sessile, the uppermost reduced to bracts. Infl. of a single terminal glomerule, or with 1-3 axillary small glomerules also. Subtending bracts seldom up to 2 cm. long. Glomerules c. 1∙5 cm. diam., with 10-20 capitula floccose-hairy at base. Capitula 3-4 mm. diam.; receptacle 1-2 mm. diam., convex; phyll. c. 5 mm. long, broadly oblong, obtuse to subacute, scarious, translucent, light brown. Achenes c. 0∙5-0∙75 mm. long, linear, not compressed. papillose and with scattered appressed white hairs. Pappus c. 3-4 mm. long, with c. 20 filiform sordid-white hairs.

Gnaphalium gymnocephalum DC.

Description

Stoloniferous perennial; stems 1-3-(6), ascending, simple, 6-25-(40) cm tall. Lvs mostly basal at flowering; basal lvs usually long-petiolate, densely white-tomentose on lower surface usually not including mid-vein, glabrous and shiny on upper (sometimes sparsely to moderately tomentose when young), plane, oblanceolate to narrow-elliptic, long-cuneate, subacute to acute, mucronate, 30-190 × 3-10-(20) mm; cauline lvs becoming slightly or not reduced upwards, often lanceolate or narrow-elliptic, apetiolate and broad-based. Capitula 1.5-2 mm diam., 10-numerous in dense ± globular terminal clusters, very rarely smaller axillary clusters below; longest subtending lvs 1-3× diam. of cluster. Involucral bracts oblong, obtuse to subacute, 3.5-4.5 mm long; stereome green; lamina pale brown, with dark band at base; gap and rarely upper margin bright reddish purple. Achenes minutely papillate, c. 0.8 mm long.
