smaller anthers than the lower; filaments glabrous ; anthers hirsute, 
mucronate at the base of each cell :. style puberulent; capsule ovate, 
acuminate, equalling the calyx-lobes; seeds oblong, light brown, the 
external seed-coat loose, cellular, and iridescent. — Hills of Zacatecas ; 
October, 1888 (n. 2183). 
CasTILLEIA MACROsTIGMA. Perennial, 8 inches to a foot high, 
nearly smooth or more or less hispid with weak spreading hairs: 
leaves small, rather numerous especially at the base, linear, acute, en- 
tire, subamplexicaul, 1-3-nerved, 9 to 15 lines long, seldom exceed- 
ing a line in breadth; floral leaves broader and shorter, lanceolate or 
narrowly ovate, angled or sparingly toothed toward the apex, often 
' yellow-tipped: flowers closely sessile in a short spike, slender, 8 to 12 
lines long, surpassing the bracts; calyx light yellow, equally cleft be- 
fore and behind, the lobes emarginate or two-toothed ; corolla a third 
longer than the calyx, yellow, the lower teeth linear, acuminate, erect: 
stigmas conspicuously exserted, thickish, sometimes more than a line 
long, recurved. — Grassy slopes, Flor de Maria, Mexico ; July, 1890 
{n. 3194). This appears to be the same as Mr. Pringle’s n. 1545 
from Chihuahua, which was distributed under the provisional and 
unedited name of C. lithospermoides, HBK., var. (?) flava, Watson. 
Specimens of this number differ from 3194 chiefly in being more his- 
pid and in having the stigmas less prominently exserted, which differ- 
ences may be in part due to the less advanced stage of development. 
Both plants differ from C. lithospermotdes in the size and color of the 
corolla, in the deeply cleft conspicuously exserted stigma, and also in 
the shorter relatively thicker and more coarsely reticulated seeds. 
RvELui1a Boure st, Hemsley. The mature capsules of this species, 
which were wanting in the type specimens and could not therefore be 
described; are excellently shown in Mr. Pringle’s n. 2951 (barranca 
near Guadalajara, September, 1889). They are rigid, lanceolate, 
acutish, euspidate, glabrous, 2 to 21 inches long and 4 inch broad, the 
valves with a conspicuous median furrow; hooks ascending, bifid; 
seeds orbicular, nearly 3 lines in diameter. 
Justicia PRincuet. Herbaceous, 2 feet high, hirsute with spread- 
ing white hairs: leayes ovate, acuminate, entire, petiolate, 1} to 24 
inches long, half as wide; the lowest smaller, orbicular, obtuse: flowers 
small, distant, borne in a spreading panicle ; lower bracts foliar, ovate, 
the upper much smaller, lanceolate; bractlets minute, awl-shaped, half 
the length of the calyx; calyx-teeth 4, narrowly linear, attenuate, 
24 to 3 lines long; corolla 4 to 5 lines long, pale rose-color, the limb 
nearly equalling the tube, the upper lip narrowed to a retuse summit,
