sprinkled with very minute points on the back. Involucre 14 lin. long, 
2} lin. in diam., cup-like, with an erect margin, overtopping the 3 lin.- 
long fringed inner lobes, puberulous outside. Ovary smooth, 2-winged

2), M. fwambense, .V. /. Br. Stem apparently annual and arising 
from a tuberous rootstock, erect, about 6 in. high in the only specimen 
seen, somewhat swollen and } in, thick for about 1 in. up from the base, 
the remainder in the dried state about ;, in. thick, glabrous. Leaves 
alternate, erect or ascending, 14-13 in. long, }-} in. broad, narrowly 
lanceolate or linear-lanceolate, about equally tapering from the middle 
to an acute apex and a subsessile base, glabrous on both sides, with an 
acute wing-like keel } lin. broad at the base along the midrib beneath. 
Cymes very small, axillary, solitary, pendulous, ultimately composed of 
3 (or more?) involucres, in the immature specimen about } in. long, 
glabrous in all parts; peduncles 1-14 lin, long, abruptly recurved, 
with 2 narrow wing-like keels. Bracts usually united into an acutely 
2-lobed cup 24 lin. long and 2 lin. broad, with 2 acute wing-like keels 
down the back, but sometimes free nearly or quite to the base and 
then narrowly deltoid or deltoid-lanceolate, acute, wing-keeled down the 
back, herbaceous, with only the keel-vein visible, glabrous. Involucre 
(including the very short stout pedicel) rather more than } in. long, 
ro in. in diam., cup-like, truncate at the top, with a thickened erect 
entire margin, open to half-way down in front, much overtopping the 
$ lin.-long fringed inner lobes, glabrous; ovary (very young) glabrous.

tuberous rootstock and annual, 3—5 in. high, }-} in. thick when dried, but 
apparently somewhat fleshy, glabrous. Leaves alternate, sessile, fleshy, 
13-2} in. long, 4-1 in. broad, linear-lanceolate or narrowly lanceolate, 
acute, tapering to the base, much crisped and wavy along the margins, 
glabrous on both sides. Cymes terminal, pedunculate, once or twice 
forked, with 3-7 involucres, glabrous; peduncle }-} in. long, with 
branches 3-3 in, long. Bracts apparently free at the forks of the 
Cyme, ovate-lanceolate, acuminate, and united into an oblique cup 
about 23 Jin. long under the terminal involucres, divided to the base in 
front and to half-way down behind into 2 ovate very acuminate lobes, 
glabrous. Involucre when fully grown about 2 lin. long and 1? lin. in 
diam., open to half-way down in front, with 4 distinct crenations at the 
top of the. erect margin, overtopping the fringed lobes, glabrous. Ovary 
only seen in a very immature condition, apparently without a periantl,
