plant resembling H. sessiliflora, Benth., but well distinguished by its 
coarser habit, larger leaves and pedicelled flowers, narrower capsule, 
thicker style, and larger seed. 
yschoriste saltuensis. A slender suffrutescent plant: stems 
branching, subtetragonal, densely covered with short appressed hairs, 
ciliate at the nodes: leaves lanceolate, obtuse at the tips, tapering below 
into short petioles, the lower cauline 6 cm. long, 1} cm. wide, the upper 
scarcely half as large, above covered with obscure linear markings, be- 
neath strigillose-pubescent on the midrib: flowers axillary, solitary, or in 
glomerules of 2 to 5: peduncles 3 or 4 mm. long: bracts minute: calyx 
hirsute, 8 or 10 mm. long, divided half way to the base into 5 lance- 
subulate lobes: corolla light purple, pubescent without, 14 cm. or less in 
length, the slender tube equalling the calyx and then spreading into 4 
campanulate throat; lobes oblong, truncate, 4 mm. long: stamens didy- 
mous, hirsute; anther-bases mucronate : style hirsute: mature fruit not 
seen, but the young capsule oblanceolate, glabrous, hardly equalling the 
calyx. Common among oaks in the higher mountains, January, 1895

Ruellia albiflora. A small shrub: the pale brown bark covered 
with prominent ovate lenticels; upper branches, with the leaves and 
calyces, covered with pellucid or black granules: leaves mostly on the 
upper branches, oblong-lanceolate or narrowly ovate, tapering about 
equally to the bluntish tips and the short petioles (4 to 7 mm.) ; leaves of 
the primary branches 4 to 10 cm. long, 1} to 44 em. wide, slightly ap 
pressed-pubescent on the midribs beneath, and with a few linear markings 
upon the epidermis above; those of the branchlets crowded and smaller, 
becoming even 1 cm. in length: flowers subsessile in the axils of the 
upper leaves, subtended by linear-spatulate bracts about equalling the 
calyx: calyx minutely puberulent, the tube 4 mm. long, the 5 lanee- 
subulate lobes 6 or 8 mm. long: corolla white, puberulent without ; the 
tube slender, 2 cm. long, spreading into a narrowly obconic throat 1 em. 
high ; limb with ovate lobes 8 mm. long: filaments sparingly pubescent ; 
anthers linear, 2 mm. long: style hirsute; stigma 1 mm. long: pod nar- 
rowly obovate, 12 mm. long, 4 mm. wide, somewhat dorsally compressed, 
blunt above, subcuneate below, minutely white-puberulous ; seeds 2 to 4, 
suborbicular, 3} mm. long, appressed-pubescent, tipped by a minute white 
caudate appendage. — Collected at Acapulco, November, 1894 (n0- 49); 
and formerly at Armeria (Palmer, 1891, no. 1274). This shrub is very 
showy in flower, and at Acapulco it grows abundantly in river bottoms 
and low rich spots among the mountains, where it is called Tronador-
