pitted. — In crevices of cliffs at the summit of the Sierra de la Silla, 

 at 5,000 feet altitude; June, 1889 (n. 2545). With wholly the habit 

 of forms of E. campestris, differing in the smaller involucres, longer- 

 appeudaged glands, and in the seeds. 



AcALTPHA DioiCA. "Woody at base and apparently perennial, the 

 erect stems sparingly branched, 1 or 2 feet high, finely pubescent, 

 the pubescence on the upper surface of the leaves short-villous and 

 subappressed : leaves ovate-lanceolate, short-acuminate, rounded at 

 base, rather coarsely crenate-serrate, 1 or 2 inches long, on petioles 

 3 or 4 lines long : flowers dioecious (or the fertile spikes bearing only 

 a rudimentary staminate flower at the apex) ; spikes all axillary, the 

 staminate slender (1 to IJ inches long), dense, long-pedunculate, the 

 fertile nearly sessile, loosely few- (3-8-) bracteate ; bracts reniform, 

 5-7-toothed, 1-2-flowered : capsule pubescent : seed globose, nearly 

 smooth. — On limestone ledges near Monterey; June, 1889 (n. 2417). 

 Resembling A. glandulosa, Cav., but the pubescence not at all 

 glandular. 



Nemastylis brunnea. Bulb dark-coated, 6 to 8 lines in diam- 

 eter : stem nearly a foot high, bearing a single leaf 6 inches long, 

 sheathing below and plaited above, and a concave sheathing acumi- 

 nate bract subtending and equalling the peduncle ; spathe several- 

 flowered, 2^ inches long : perianth maroon-color or brownish purple, 

 6 lines long, the outer segments obtuse, the inner as long and similar, 

 but acuminate and tipped with yellow : stamineal column a line long 

 or more, the yellow anthers (2^ lines long) with a broadish connect- 

 ive : style-branches scarcely shorter, cleft nearly to the base, stig- 

 matic half their length, bearing a filiform purple appendage in the 

 sinus. — Described from flowering plants raised from bulbs collected 

 near Guadalajara in 1889. 



Zephyranthes erubescens. Bulb ovate, dark-coated, over an 

 inch in diameter, the neck as long: leaves about six, 6 to 15 inches 

 long by 2 or 3 lines broad, concave, not carinate, glaucous : scape 6 

 inches high ; spathe tubular, bifid above, the tube equalling and 

 closely embracing the pedicel (about an inch long) : perianth 2 inches 

 long, rather narrowly funnelform, white strongly tinged with rose- 

 color without, the tubular base greenish : filaments very short, in- 

 serted on the throat, the slender anthers (3 lines long) exceeding 

 the shortly lobed stigma. — Locality uncertain, but probably from 

 sandy plains in Duval County, Texas, — perhaps northern Mexico; 

 1888. Described from plants in flower at Cambridge, August, 1889. 

 Near Z. Lindleyana.
