Near S. miser Hook. Heads solitary on branches. Rhizome long- 
fibrillose, branching, bearing many stems. Stems low, 8--10 cm, naked 
and scarred at the base, densely leafy and branching upwards, the 
branches ending in a 10—15 mm peduncle and head. Leaves linear- 
spatulate, attenuate-petiolate, entire or toothed near apex; the upper 
webby to tomentose. Heads small, campanulate. Involucral scales linear, 
their margin broad scarious. Flowers?

32. Senecio danyausii Homb. & Jacq. var. pinnatifidus Macl., 1. c., p. 843. 
Very like S. danyausii lobatifolius, except that the leaves are somewhat 
more deeply serrate or pinnatifid. (Determined by Dr. O. Hoffmann.)

The described branch is 24 cm high. Lower leaves somewhat crowded, 
about 25 mm long, 12 mm broad; the upper leaves gradually smaller. 
Heads 4 at apex of the branch, but in one strict lateral branch 3. Pedi- 
cels 4—8 cm long. Involucre 1 em high and slightly narrower. Corollas 
of ray with a slender tube, 5 mm long; ligules 12 mm long, 3 mm broad, 
tridentate, 4-lineate, closely resembling S. ofaeguianus Phil, but differing 
by its broader leaves, bracted pedicels and by having a calyculus.
