curved smooth with a membranous tubular dimidiate or au- 
ricidate crown or pappus sheathing the Jl.-tube. — Herb. ann. 
L. alternate. FI. wholly y. 
fl4. Chrysanthemum. Like Myconia, but fl. of ray fertile 
with a perfect forked style , scales of inv. unequal imbricate, 
ach. of ray fertile triquetrous with the 2 side angles only 
winged and the back 8-ribbed, of disk turbinate-cylindric 
equably 10-ribbed all round ; all simply truncate without 
any pappus, crown, or tooth.- 
fl5. Pinardia. Like Chrysanthemum, but ach. of ray tri- 
quetrous with all the 3 angles especially the inner sharply 
winged '■ and the sides obsoletely 1-3 -ribbed, of disk com- 
pressed the inner angle only winged the back bluntly keeled 
and sides 2S-ribbed; all reticulate-rugulose or granulate 
and abruptly truncate with the wing or wings ending in a 
laterally prominent or horizontal tooth or beak at the top but 
without any crown or pappus. — Herb. ann. L. alternate 
scattered. FI. pale straw or golden y. 
16. Argyranthemum. Like Pinardia, but ach. of ray 
incurved or boat-shaped much as in Calendula, and all (both 
of ray and disk) not truncate but with a distinct dimidiate 
obliquely unilateral or intro-secund coriaceo-membranous 3- 
4 -toothed crown or pappus. Recept. naked conical. — Shr. 
altogether smooth, peculiar to the Mad. and Can. Islands. 
L. somewhat fleshy alternate crowded towards the ends of 
the branches, bipinnatisect. Scales of inv. broadly and con- 
spicuously scarious. FI. terminally corymbose: ray w. 
rarely rose, disk golden-y. rarely atropurpureous. Tube of 
fl. in Mad. sp. ( Stigmatotheca Schultz in WB.) either alto- 
gether smooth or resinoso-punctate, in Can. sp. ( Argyranthe- 
mum Schultz in WB.) mostly glandular-pubescent. — Easily 
distinguished at once from the 3 or 4 preceding genera by 
the shrubby habit, boat-shaped seeds and conical recep- 
tacle. 
B. Becept. chaffy, wholly or partly. 
Tribe X. ANTHEMIDEsE. 
(Like Chrysanthemcce except the chaffy recept.) Heads 
mostly lieterogamous ; fl. of margin mostly ligulate female 
(sometimes neuter sterile) in a single row, rarely 0; of disk 
(or rarely all) perfect tubular regular. Branches of style in 
perfect fl. linear with a pencil or tuft of hairs below the truncate 
or produced conoidal tip. Recept. cliafly mostly conoidal. 
Ach. variously shaped mostly ribbed. Pappus mostly 0 or ob- 
solete, rarely a short, complete or dimidiate or /5-toothed crown.
