ROBINSON AND FERNALD. — MEXICAN PLANTS. 115 



fine cotton is used for making wicks for tapers of wild beeswax. Thi8 

 species is to be distinguished from E. tomentosum, Robinson, by its 

 glabrous calyx and relatively broader leaflets. 



EsENBECKiA Haktmanii. A shrub, 6-10 feet high : twigs thick, 

 woody, covered with gray bark, leafy chiefly near the end : leaves 

 simple, alternate, oblong or somewhat obovate, entire, rounded or re- 

 tuse at the apex, somewhat narrowed below to an obtuse or rounded 

 base, thickish, green, nearly smooth and finely reticulated above, 

 tomentulose and scarcely paler beneath; the largest ones 16-20 lines 

 long, 8-11 lines broad; the others considerably smaller (8-9 lines in 

 length) ; petioles short, soft pubescent, 1-1 J lines long: inflorescences 

 short, terminal upon the branchlets ; fruiting pedicels 1-3 together, ^ 

 inch or less in length : the capsule tuberculately roughened, 9-10 lines 

 in diameter ; pericarp white, thin and chartaceous, rather irregularly 

 ruptured upon dehiscence; seeds subglobose, smooth, black, 3^ lines 

 in diameter ; scar white, narrow, linear, h line in breadth. — Collected 

 in fruit at La Tinaja, Sonora, at 3,700 feet, by Mr. Hartman, 19 No- 

 vember, 1890 (no. 240). This species much resembles the Lower 

 Californian E. Jlava, Brandegee, but differs in its smaller greener 

 shorter-petioled leaves, and its smaller fruit with chartaceous and not 

 cartilaginous pericarp. The seeds of E. jiava also are larger and 

 have a much broader scar. 



Ilex rubra, Wats. (Proc. Am. Acad. xxi. 422). Flowering 

 specimens of tliis species, which was originally described in fruit, have 

 been collected in an arroyo near Coloradas, by Mr. Hartman, May, 

 1893 (no. 513), and add the following characters : flowers numerous, 

 in small aggregated thyrses, greenish white, 4-parted: calyx lobes 

 ovate, obtuse, % line long : corolla nearly 4 lines in diameter, about 

 equalling the stamens ; the lobes rounded. 



Dalea Lumholtzii. Stems many, slender, puberulent, punctate 

 with yellow glands, simple or sparingly branched, erect from a decum- 

 bent much branched sufFrutescent base : upper leaves erect or ascend- 

 ing, 1-1| inches long, leaflets 17-27, linear, 2-2^ lines long, nearly 

 \ line in breadth, obtuse, slightly narrowed to very short petiolules, 

 glabrous, glaucous and glandular-punctate upon both surfaces ; the 

 basal leaves numerous, shorter, and with considerably smaller almost 

 filiform leaflets, silky under a lens : spikes ovate, capitate, 3-7 lines in 

 length, becoming oblong, very densely flowered, covered with closely 

 imbricated persistent bracts ; the latter ovate or obovate, very ab- 

 ruptly pointed, silky upon the margins and especially near the some- 

 what narrowed base ; glabrate and glandular-punctate upon the back,
