limb: styles a line long: capsule rugose, broadly ovate with depressed 
summit. — Collected by C. G. Pringle, on hills near Tehuacan, Puebla, 
altitude 5,500 feet, 24 December, 1895, no. 6286. A very attractive 
species, nearly related to V. latifolium, Gray, but with much longer calyx 
and larger corolla as well as different pubescence. : 
Nama Pueblense. Slender weak dichotomously branched annual, 
3 to 6 inches high, spreading-pubescent: leaves ovate, obtuse, entire, 
thin, 10 to 12 lines long, half as broad, rather abruptly contracted to a 
slender petiole and covered on both surfaces with fine sub-appressed 
hairs with globular bases ; and below with short golden yellow pedicelled 
glands: flowers short-pedicelled, grouped by 2’s or 3’s near the axils or 
extra-axillary and solitary somewhat above the fork of the terete purplish 
stem: calyx-lobes in fruit 4 lines in length, spatulate, densely hirsutu- 
lous with spreading white hairs: corolla small, pale blue (in dried speci- 
men), tubular, with scarcely ampliated shortly 5-lobed limb, 2 to 24 lines 
‘long: styles half line in length: capsule narrowly oblong, hispidulous 
near the apex, rugose, about, 2 lines in length, obtusish: seeds brownish, 
Tugose. — Collected by C. G. Pringle, on hills near Tehuacan, Puebla, 
altitude 5,500 feet, 24 December, 1895, no. 6287. MHabitally near to 
N. latifolium, Gray, but differing in its much longer more hirsute calyx, 
harrower capsule, and having leaves evenly pubescent over the entire 
surface instead of chiefly on the veins. 
Berendtia levigata. Shrub 2 to 3 feet high, glabrous but some- 
what vernicose especially upon some of the younger parts: stems and 
branches covered with a gray bark; branchlets very leafy especially at 
the ends: leaves rather broadly lanceolate or oblanceolate, sharply few- 
toothed above the middle and acute, cuneate to an entire short-petioled 
base, glabrous or (under a lens) slightly pulverulent but green on both 
surfaces and sometimes a little lucid, of firm texture, 1} to 1} inches 
long, half as broad: peduncles opposite in the upper axils, 1-flowered, 
bibracteolate at or below the middle, the bractioles bearing rudimentary 
buds in their axils : calyx strongly prismatic, as in Mimulus, 6 lines in 
length, with 5 short broad subequal acuminate-mucronate’ teeth : corolla 
showy, much exserted, 1} inches in length; throat rather gradually 
ampliated, orange with crimson spots; limb patulous, of broad rounded 
lobes: stamens searcely exserted: capsule 6 lines in length. — Collected 
by. C..G. Pringle, on calcareous hills near Tehuacan, Puebla, altitude 
9,500 feet, 24 December, 1895, no. 6294. 
Castilleia aurea. Slender annual of § Epichroma, a foot high, 
with terete glabrous flexuous branched stems and delicate pectinate
