2. M. divaricatum (Rich.) DC. Prod. 5; 520, 1836, Hoff. 
in Die Nat. Pflantzenf. 4; 218, 1897. Dysodium divaricatum 
Rich. in Pers. Ench. 2; 489, 1807.—Stems herbaceous, dic- 
hotemous, pilose. Ovate leaves acuminate, base cuneate, 
coarsely dentate, scabrous above, hispid beneath. Peduncles 
of dichotemous heads glabrous, often exceeding the leaves; 
outer involucral bracts 5, obovate, base united; achenes com- 
pressed, rugose, apex truncate and externally obscurely den- 
tate; ligule short, 3-toothed. 
There are no specimens in the herbarium, but we do 
not doubt that this widely distributed species occurs within 
our region. 
29. CHRYSOGONUM LINN. 
Caulescent perennial herbs, with opposite (in ours alter- 
nate) pubescent leaves. Heads heterogamous, solitary, corym- 
bosely arranged, yellow; marginal flowers ligulate, fertile; 
disk flowers perfect, sterile, tubular limb elongated and 
5-toothed; involucre ovoid, its bracts rather rigid; receptacle 
flat, set with persistent concave scales; anther bases sub- 
sagittate; style of disk flowers undivided, hairy; ray achenes 
dorsally compressed, margins acute, l-ribbed on the back, 1 
to 2-ribbed on the inner face; pappus a half cup shaped

more especially along the nearly parallel veins beneath, 
apex rounded or obtuse, base cuneate or truncate, 5 em- 
long, 2 em. wide, oblong to linear ovate, coarsely and repandly 
toothed. Inflorescence a few branched racemes, the lower 
branches longest and equalling the central ones, densely 
yellowish pubescent, leaf bracteolate; heads solitary, 15 mm. 
in diameter, 1 cm. high, ovoid, subcampanulate; bracts of 
the involuere densely woolly, 1 to 3-seriate, subequal in
