glandular or resinoso-punctate. Branches of style w. moderately 
long but much, shorter and less conspicuous than in A. mexi- 
canum Sims and scarcely clavate. Recept. naked conico-pul- 
vinate or mamillate. Pappus of 5 radiating lanceolate pale 
straw-coloured (not w.) stiff chaffy-setaceous very rough awns 
membranously dilated and strongly serrulate irregularly down- 
wards, about one line long. Ach. small 1 line long black 
shining strongly or sharply 5-angular narrow-oblong truncate 
at top scarcely attenuated downwards smooth except a few re- 
mote short glittering points or erect setules with which the 5 
angles are serrulate or ciliate ; basal areola or scar oblique’ tumid 
yellowish or brownish ivory-w. 
In withering or drying the fl. give out the scent of new- 
mown hay or Woodruff' ( Asperula odorata L.), mixed however 
with a strong unpleasant odour. Otherwise the pi. is wholly 
scentless. 
The chaffs or awns of the pappus are more gradually dilated 
downwards and roughly or coarsely serrulate than in A. mexi- 
canum ; they are also distinct, not imbricated laterally, quite 
down to the base ; the ach. are uniformly black shining and 
very finely and minutely but distinctly striolate both longitu- 
dinally and transversely, with the oblique callous w. ring or 
scar at the base larger and more tumid. 
The common Cape Verde pale-b.- or lilac-fid. var. of this pi. 
is said by Schmidt (Fl. Cap. Verd. 184) to be the same as he 
had observed in Mad., which is quite at variance with my ex- 
perience. Nor on the other hand did I ever meet with A. 
conyzoides var. Mexicanum DC . = A. Mexicanum BM. t. 2524 
which he includes in his syn., in any of the Cape Verde islands. 
tf2. A. mexicanum Sims. 
Perennial herbaceo-suflrutescent thickly furry-pubescent; st. 
and branches altogether round and even throughout, shrubby 
and smooth downwards; 1. hispid-pubescent rhomboidally or 
triangularly oblong-ovate acute sharply serrate often twice as 
long as broad ; scales of inv. hirto-pubescent entire ; fits, glan- 
dular-pubescent ; styles very long ; pappus erect close and la- 
terally imbricate at base ; ach. quite smooth and even, sprinkled 
or ciliate up the angles with short erect setules. — BM. t. 2524.
