Van. f. gracilis ; inv. scales in few rows, rigid, less membranous. Herb. Th.! 
Has. Common near Capetown and in the Western Districts. Var. 8. Steendahl, 
near Tulbagh, Dr. Pappe! (mixed with a). (Herb. Th., D., Hk., Sd.) 
Stem woody at base, about a foot high, corymbosely branched, woolly or glabrous, 
more or less scabrous. Leaves crowded, 10-12 lines long, not § line broad, linear, 
acute, with reflexed margins, tomentose or nude, more or less sprinkled or margined 
with stalked glands. Pedunce. terminal, nude, glabrous, spreading, 2-3 inches long. 
Heads many-fl.; the rays yellow above, brownish-red on the underside. Inv. scales 
in a. in very many rows, with widely membranous borders ; in 8. (otherwise quite 
similar) in much fewer rows, more rigid, with narrow, scarcely membranous edges. 
All the specimens in Herb. Thunb. belong to this variety, which is by no means so 
common as a. Drege’s specimens of “ LZ. tenella, var. subcanescens” (in Hb. 8d.!) 
belong to it also. 
2. L. incana (Thunb.! Cap. 691); suffruticose; inv. scales (or at least 
the outer ones) lanceolate, acuminate. Less./ Syn. 369. DC, l. c. 278. 
Has, Cape, Thunberg! Round Capetown, Ecklon! W.H.H. (Hb. Th., Hk., Sd.) 
Only known from L. gnaphalioides by its taper-pointed iny. scales, a character 
sometimes strongly marked, but very variable, when a large number of specimens 
are examined, and I fear not to be trusted to as a specific difference. 
3. L. tenella (DC.! 1. c. 279); very slender, wiry ; leaves very slen- 
der ; inner inv. scales folding at base round the ovary and closely clasping 
the marginal achenes, linear, subacute; pappus of the ray of 5 oblong, 
toothed scales, of the dise of 5 obtuse scales and 5 bristles feathery at 
top only ; tubular fl. with a very scabrous tube. 
Has. Zach River, Burchell. Silverfontein, Drege! Namaqualand, Zey! (Herb. Sd.) 
Similar in aspect to L. gnaphalioides var. B., but still smaller and more slender, 
and always to be known by the pappus bristles (in the disc fl.) being feathered at 
their apex only. Some (at least) of Drege’s distributed specimens of “‘Z. tenella var. 
” have the fully plumed us of L. . B pracilis, to-whaale

scarious pale. nv. imbricate, the scales dry, membrane-edged. An-

of the disc terete, furrowed. Pappus of the disc-flowers in two rows, 
the outer of many short, broad scales, the inner of 2 long bristles ; of 
the ray of many short scales in a single row. DC. Prodr. 6. p. 280.
