Sept. — Root vertical long and simple. St. mostly dark purple, 
sometimes several branched from the root and ascending or 
diffuse, sometimes simple erect and branched only upwards; 
branches once or twice proliferously subdivided, widely forked 
or spreading, hard and stiff or rigid, villous and greyish-hoary 
like the 1., each ending in a solitary fl. L. in. long, 2-4 
lines broad, mostly rather inconspicuous or scanty, the 3 or 4 
uppermost pinnae usually much longer than the rest. Heads 
solitary at the ends of the st. and branches, not corymbose, each 
rising above its predecessor and flowering later, so that there 
are seldom more than 2 or 3 open together on a branch or stem. 
Ped. slender villous-pubescent not thickened upwards. Fl. 
£-1 in. in diam., like those of Anthemis Cotula L. but with the 
w. rays or ligules y. at the base often styliferous and fertile 
and perhaps broader shorter and fewer ; always at night and 
soon permanently strongly reflexed. Disk golden-y. Tube of 
fl. of disk 2-3-angular or winged, the inner angle produced 
downwards into a distinct pointed hood covering the top of 
the ach. Scales of inv. villous, never reflexed. Recept. in fr. 
conico-cylindric, hard and woody, chaffy all over. Chaffs at all 
times shorter than and concealed by the fits., pilose towards the 
tip, conduplicate downwards and embracing the ach., pale straw 
with the keel and tip bright chestnut. Ach. small 1 millim. 
long, not quite half as broad, pale dull greenish drab, oblong- 
obovate or clavate obcompressed, obliquely rounded and im- 
marginate at top without any crown, rim, edge or border, 
smooth and naked but finely and closely striolate longitudi- 
nally, with 3 often obscure and obsolete equal obtuse ribs (1 
central, 2 marginal) on the inner side. Epigynous disk small 
oblique or excentric. 
Godron’s genus Cliamomilla differs only in extent and not in 
characters from Ormenus Cass, which it therefore cannot su- 
persede.
