GREENMAN. — MEXICAN PHANEROGAMS, 567 
This species seems most nearly related to Z. acicularis, R. Br., but 
differs in the stouter habit, the more conspicuously sheathed culms, and 
the more persistent and longer seta. 
Smilax Pringlei. Stems terete, unarmed, somewhat tawny-pubes- 
cent, later becoming glabrous or nearly ‘so: leaves alternate, ovate or 
ovate-oblong, 7 to 12 cm. long, 4 to 6.5 cm. broad, cordate or occasion- 
ally subtruncate, short-acuminate, acute, entire, 5-7-nerved with rather 
prominently reticulated veins, glabrous above or slightly pubescent on 
the nerves, more or less pubescent beneath, later becoming glabrous ex- 
cept on the rather densely hirsute-pubescent nerves; petioles 1.5 to 
2 cm. long, pubescent, ceriferous near the base: peduncle 2 to 4.5 cm. 
long, pubescent ; pedicels 6 to 12 mm. long, these as well as the slender 
flirwentrci grayish-puberulent: perianth-divisions of the staminate flow- 
ers linear-oblong, 6 to 8 mm. long, 1 to 1.5 mm. broad, obtuse, 1-nerved, 
in anthesis recurved: pistillate flowers not seen: mature fruit smooth, 
globose, about 1 em. long; seeds ovate, 5 mm. long, 38 mm. broad, red- 
dish-brown. —Collected by C. G. Pringle in a barranca near Cuernavaca, 
State of Morelos, 20 November, 1895, no. 7060, and in the same locality 
at an altitude of 1,800 m., 18 June, 1896, no. 7259, also in mountain 
caiion above Cuernavaca, altitude 2,000 m., 15 May, 1898, no. 6843. 
A species climbing to 6 m. and most nearly related apparently to 
S. erythrocarpa, Kunth, from which it is distinguished by the pubescent 
character and by the shorter peduncles. 
Agave (Litteea) intrepida, Acaulescent: leaves numerous in a 
rosette, lance-attenuate, about 4.5 dm. long, 1.5 to 2.5 cm. broad, gradu- 
ally narrowed to a rather slender reddish-brown end spine, somewhat 
dilated at the base to a breadth of 2.5 to 4 cm., smooth and in the dried 
State more or less striate upon either surface, margins cartilaginous, mi- 
nutely, closely, and evenly serrulate from base to apex: scape 1 to 1.25 m. 
high, clavate: bracts of the peduncle scattered ; floral bracts lance- 
attenuate, slightly exceeding the flowers, scarious : flowers in pairs, 3.5 
to 4 cm. long: perianth-tube 1.2 to 1.4 cm. in length; lobes oblong, 
somewhat shorter than the tube, slightly thickened at their pubescent 
_ apices: stamens inserted at about the middle of the perianth-tube, over- 
topping the stigma and more than twice exceeding the perianth: capsule 
1.7 em. long, nearly 1 cm. in diameter. — Collected by C. G. Pringle on 
mossy ene Parque Station, State of Morelos, altitude 2,100 m., 2 June, 
1898, no. 6868. 
This species is apparently related to 4. dasylirioides, Jacobi & Bouché, 
but differs materially in size and habit. In Mr. Pringle’s plant the
