leaves flat, shorter than the stem, about a line wide, the cauline small 
and subfiliform: bracts subtending the branches of the panicle very 
small: fruit obcordate in outline, 3 lines long, on a pedicel 4 lines 
long. — F]. 1. 208; Baker, Journ. Linn. Soc. 18. 292. Phalangium 
virgatum, Poir. in Lam. Dict. 5. 246. §. Carolina to Florida 
(Tampa Bay and St. Augustine). Specimens from the last locality 
have thicker fruit, only 2 lines long, on very short pedicels. 
2. N. LINDHEIMERIANA. Stem stout, 2 to 6 feet high, from a very 
short caudex: leaves flat and thin, 2 to 4 lines broad below, 1 to 3 
feet long, strongly serrulate; the cauline 6 inches long: panicle simple 
or sometimes compound, the bracts not conspicuous: fruit very thin, 
emarginate at both ends (more deeply above), wider than long (5 lines 
broad), on pedicels about 4 lines long. — Dasylirion Lindheimerianum,

3. N. Microcarpa. Stem stout, 6 feet high, from a short caudex: 
leaves concavo-convex, rather thick and somewhat carinate, 4 to 6 
lines broad, very strongly serrulate, fibro-lacerate at the apex: panicle 
narrow, branched at base; branches slender, a foot long, with ascend- 
ing branchlets (2 or 3 inches long); bracts small: fruit as in the last 
but smaller (3 lines broad), on very slender pedicels 2 or 3 lines long: 
stigmas very short, sessile. — Dasylirion erumpens, Rothr. in Wheeler’s 
Rep. 6. 272. §. Arizona (Rock Cajion; Rothrock, n. 278). Re- 
sembling NV. erumpens: only immature fruit known. 
4, N. BreeLovir. “Scape 3 feet high”: leaves flat, nearly an 
inch wide above the broad deltoid base, not carinate, 3 or 4 feet long, 
the margin roughish: panicle compound; branchlets slender, an inch 
or two long: fruit very thin, 4 or 5 lines in diameter, emarginate 
at both ends, on very slender pedicels 2 to 4 lines long: seed ovate- 
oblong, 2 lines long, whitish, slightly reticulated. — Dasylirion Bige- 
lovit, Torr. Pacif. R. Rep. 4.151. Beaucarnea Bigelovii, Baker, 1. c. 
326. W. Arizona. The plant found by Schott in Sonora, referred 
to this species in Bot. Mex. Bound. 216, is probably distinct, but has 
not been seen for comparison. 
5. N. Parryr. Resembling the last: caudex 5 to 6 feet high: 
leaves thicker and somewhat concave above, especially toward the 
stout apex, very strongly serrulate on the margin: branchlets of the 
panicle and the pedicels stouter: fruit 6 lines in diameter: seed sub- 
globose, the very thin testa finely and irregularly wrinkled. — Cali- 
fornia (western border of San Bernardino Desert; Parry, 1876).
