ments wanting, inserted into the base of the throat, the anthers. 
included, linear oblong, dorsifixed, the base entire. Disk not 
prominent, fleshy; ovary 2-celled; style filiform, included or 
barely exserted, the branches 2, linear. Placente fixed along 
the central portion of the septum, the ovules rather numerous in 
the cells. Capsule globular, costate, the calyx limb imperfectly 
deciduous, crustaceo-cartilaginous, imperfectly loculicidal, the sep- 
tum delicate, early separating from the walls to simulate a one- 
celled capsule. Seeds rather few, peltate, pendulous, imbricated 
in two ranks in each cell, circular, saucer-shaped, both as to the 
body of the seed and by the incurved wing. Embryo straight, in 
semi-corneous albumen, with well-developed caulicle and cotyle- 
dons. 
A much branched ragged shrub (or tree?) with short spine- 
like leafy branchlets, the leaves minute, oblong-linear, semi-fleshy, 
_ crowded, the stipules obscure, somewhat sheathing: 
Named in allusion to the striking saucer-shaped seeds. 
L. tyciorwes. Bark gray, branches numerous, divergent, very 
~ unequal, rigid, leaves 3-5 mm. long, I-2 mm. broad, on very 
short petioles, elliptical-oblong, entire, thickish, below granular, 
roughened, with prominent mid-rib, drying blackish; flowers 
(color?) terminal, solitary, peduncled; calyx 4 mm. long, the 
lobes 3 mm. long by .5 mm. broad, strap-shaped, slightly 
broadened upward, thickish, obtuse, the sinuses open; corolla 
nearly 2 cm. long, the tube very slender, the spreading limb 
' nearly 1 cm. broad, the lobes broadly ovate, acutish; fruit 
pendulous on stout, very tough peduncles, globular, light- 
brown, 6 mm. in diameter, 10-costate; seeds nearly 3 mm. 
broad, hispid. Collected by Mr. Miguel Bang near Cocha- 
bamba (Nos. 1121 and 1122). Distributed as “ Randia.” 
COMPOSITE. 
My third genus has the homogamous, tubuliflorous heads, the 
Sub-entire anther base, the sub-terete, obtuse, papillose style- 
branches, and the setose pappus of the 2d tribe, Eupatoriacee. 
Of its 3 sub-tribes, it has the appendaged anthers and the 5-angled 
akene of the Ageratee. The pappus, entirely setaceous and of 
numerous setz, exclude it from the Ist group of this sub-tribe. 
Between the 2d and 3d sections it is difficult to decide, as one of 
these is described as “insigniter barbellata,’ the other ‘ dbreviter 
barbellata.” On the whole, however, its affinities seem rather with 
the more strongly barbellate first section, notwithstanding that
