47. COMPOSLTACE-E. 
divaricate, forming a loose few-fld. irregular cyme. Heads 
in bud oblong, in fl. slightly ventricose as in Sonchus at the 
base, more so in fr. and ovate, smooth at top, glandular- 
pubescent at the base. Outer scales of inv. (calycle) short not 
half the length of inner, quite smooth, linear-lanceolate, with 
black or purplish points and edges, at first close-pressed, but 
soon withering at the tips and becoming lax and spreading ; inner 
scales 10-12 twice as long linear fleshy densely glandular-hispid 
at the base with short hairs like those of the ped., but not for 
the most part black or dark purple, with a few indistinct mealy 
whitish cottony hairs at their edges or interstices, but except 
in /3 scarcely enough to give any farinose appearance, quite 
smooth and shining upwards above their middle and nearly or 
quite smooth inside. The roughness or hairiness outside of 
the lower part of the inner scales appearing between the per- 
fectly smooth outer scales, contrasts remarkably with the latter 
and with their own smooth upper portions. Heads in fr. 
considerably enlarged with the scales very fleshy ; ovate, 
pointed, tipped with the slightly exserted pappus, swolleu at 
the base. Ach. dark brown or black fusiform slender produced 
into a short slender beak, many-ribbed, the ribs minutely ser- 
rulate transversely. Pappus simple dirty or dull w. silky short 
but copious, rather shortly but distinctly stalked. Cells of 
recept. fimbriate. 
The base of the glandular capitate hairs or setules is dilated 
longitudinally, like the prickle of a Rosa or Ruhus , and on the 
st. and ped. is blackish or dark purple though the hairs them- 
selves are not so always, and indeed, on the base of the inner 
scales <3f inv., are mostly altogether gr. or colourless. 
This pi. is much sought after by the Machico people anil 
brought over in boat-loads from the llheo dos Embarcadores 
on P ta de Sao Louren^o in April and May to feed their pigs. 
■'*. C. HEERACIOIDES Lowe. 
Jlienn. light apple-gr. ; st. fistulose erect paniculately 
branched from the base upwards throughout with a single 
amplexicaul 1. at each fork or division and at least upwards, 
together with the ped. and heads, more or less eclnnulato- 
hispid with short capitate black setules or hirtose with longer 
simple black spreading hairs or bristles ; rarely nearly smooth 
or naked; 1. smooth shining mostly undivided repandly si- 
nuate-toothed or with waved shallowly repand-tootned or re- 
motely setuloso-denticulate edges, rarely runcinato-pinuatifid, 
with the strong pale whitish midrib beneath more or less 
hirtose and the upper 1. often fringed at the edges with black 
or purple bristly hairs or setules, the root-1, oblong-lanceolate 
much attenuated downwards, the st.-l. sessile amplexicaul
