GREENMAN, — SPERMATOPHYTES FROM MEXICO, ETC. 253 
stamens 3, exserted : corolla of the pistillate flowers similar but smaller, 
5-lobed to the middle: style exserted: fruit oblong-ovate, 6 to 6.5 mm. 
long, two-thirds as broad, crowned by the persistent plumose calyx-teeth, 
strongly compressed, unicostate on one side and 3-ribbed on the other, 
puberulent to essentially glabrous. — Mexico. State of Mexico: hills 
near Lecheria Station, altitude 2225 m., 4 July, 1904, C. G. Pringle, 
no. 8998 (hb. Gr.). This species is closely related to, and possibly may 
prove eventually to be the same as, the inadequately characterized and 
obscure V. Napus, Lindl., but until more can be learned of the Lindley 
species and its identity established it seems best to regard Mr. Pringle’s 
plant as representing a distinct species. 
Valeriana Nelsonii, n. sp. An erect herbaceous perennial : stems 
5 to 7 dm. high, simple or sparingly branched above, striate, glabrous, 
often purplish at the base: leaves bipinnatisect, oblong to oblong-ovate 
in general outline, including the petiole 6 to 24 cm. long, one-third as 
broad, glabrous ; segments linear, 0.5 to 6 cm. long, 1 to 3 mm. broad, 
acute or obtusish ; petioles 5 cm. or less in length ; stem-leaves 1 to 2 
pairs, the upper often reduced to mere attenuated bracts: inflorescence 
in terminal rather close cymes ; bracts minute: flowers sessile, perfect : 
corolla subcampanulate, 3 mm. long, 5-lobed to or a little below the 
middle, roseate, proterandrous ; tube but slightly gibbous at the base, 
densely villous in the throat; lobes oblong-ovate, obtuse, spreading: 
fruit oblong, upwardly a little narrowed, 5 mm. long, 3 mm. broad just 
above the base, glabrous, compressed, plano-convex, unicostate on the 
side of the ovuliferous cell, 3-ribbed on the other side with the lateral 
ribs somewhat more prominent and rounded on the back. — Mextco. 
State of Durango: near El Salto, altitude 2400-2650 m., 12 July, 1898, 
E. W. Nelson, no. 4574 (hb. Gr.) ; El Oro to Guanacevi, 14 to 16 August, 
1898, #. W. Nelson, no. 4744 (hb. Gr.). Mr. Nelson’s specimens have 
been referred to V. ceratophylla, HBK., from which species they differ in 
having a less cespitose habit, taller stems, more crowded primary leaf- 
divisions and longer ultimate segments, and finally in the somewhat larger 
and glabrous fruit. In habit V. Nelsonii resembles V. caleicola, but it is 
readily distinguished by the glabrous stem, larger more oblong and gla- 
brous fruit.
