griseous- or ochraceous-tomentose with rather loose crisped hairs, 
feather-veined, the lateral veins about 10 pairs, plane or impressed 
above, prominent beneath, the veinlets finely prominulous-reticulate 
above, loosely prominulous-reticulate beneath; panicles terminal, 
many-headed, 9-12 cm. wide, ochroleucous-tomentose, the linear- 
spatulate or linear tomentose bracts 1 cm. long or less; pedicels 
5 mm. long or less; heads 11-14 mm. wide; disk 1 cm. high, 8 mm. 
thick; involucre 7 mm. high, bearing at base 3 or 4 linear bractlets 
about 4mm. long, the phyllaries 8, densely ochraceous-tomentose 
on their exposed surface, oval-oblong, obtuse; rays 7, yellow, the © 
lamina 6mm. long; disk flowers 16-18, their corollas yellow, 7.5 
mm. long, glabrous, the teeth papillose at tip; achenes (immature) 
glabrous; pappus bristles spinulose throughout, dilated at tip, 
6 mm. long. 3

ms to be distinct from any of the very numerous species which 
have ge described within recent years. Its closest ally is apparently G. 
caracensis Muschler, which, according to description, has leaves with appressed 
fulvescent-cinereous tomentum beneath, 8-10 ? and 11-14 ¥ flowers, and a 
somewhat different involucre. G. hypomalaca comes from the same locality 
where MANDON collected so many new species, but of the two new species 
properly belonging to the genus, briefly described by ScuHuLtz BIPoNTIUS 
from his collections, one, G. mandonii, is of a different group, while the other, 
G. asterotricha, agrees in most of the few characters given with G. hypomalaca, 
but is said to have cordate leaves. 
Mutisia sagittifolia, sp. nov.—Stem slender, supported among 
shrubs, essentially terete, obsoletely winged in places, about 2 mm. 
thick, at first densely white-arachnoid-tomentose, soon glabrate 
and brown; internodes 6-30 mm. long; leaves alternate, terminated 
by a simple cirrhus 1-3 cm. long, the blades linear or linear- 
lanceolate, 6-8 cm. long, 5-8 mm. wide, usually falcate, acute and 
unequal at apex, sessile and sagittate-auriculate at base (the acute 
ears 3 mm. long), coriaceous, entire, revolute-margined, 1-nerved, 
above quickly glabrous, shining green, impressed-venulose, beneath 
densely and persistently white- or cinereous-arachnoid-tomentose ; 
peduncles solitary at tips of branches, 2cm. long, apparently 
decurved, bearing a single small bract, tomentose like the stem;
