limb: styles a line long: capsule rugose, broadly ovate with depressed 

 summit. — Collected by C. G. Pringle, on iiills near Tehuacan, Puebla, 

 altitude 5,500 i'eet, 24 December, 1895, no. (5286. A very attractive 

 species, nearly related to N. 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 2\ lines 

 long : styles half line in length : capsule narrowly oblong, hispidulous 

 near the apex, rugose, about 2 lines in length, obtusish : seeds brownish, 

 rugose. — Collected by C. G. Pringle, on hills near Tehuacan, Puebla, 

 altitude 5,500 feet, 24 December, 1895, no. 6287. Habitally near to 

 iV. latifolium^ Gray, but differing in its much longer more hirsute calyx, 

 narrower capsule, and having leaves evenly pubesceut 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 Mimuhis, 6 lines in 

 length, with 5 short broad subequal acuminate-mucronate teeth : corolla 

 showy, much exserted, 1 h inches in length ; throat rather gradually 

 ampliated, orange with crimson spots ; limb patulous, of broad rounded 

 lobes : stamens scarcely exserted : capsule 6 lines in length. — Collected 

 by C. G. Pringle, on calcareous hills near Tehuacan, Puebla, altitude 

 5,500 feet, 24 December, 1895, no. 6294. 



Castilleia aurea. Slender annual of § Epichroma, a foot high, 

 with terete glabrous flexuous branched stems and delicate pectinate
