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, uuicostate on one side and 3-ribbed on the other, 

 puberulent to essentially glabrous. — Mexico. State of Mexico : hills 

 near Lecheria Station, altitude 222 5 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. Prmgle's 

 plant as representing a distinct species. 



Valeriana Nelsonii, n. sp. An erect herbaceous perennial : stems 

 5 tQ 7 dm. high, simple or sparingly branched above, striate, glabrous, 

 often purplish at the base : leaves bipinuatisect, 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. — Mexico. 

 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, E. 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. calcicola, but it is 

 readily distinguished by the glabrous stem, larger more oblong and gla- 

 brous fruit. 



I^lephaxtopus micropappus, Klatt, Jahrb. Hamburg, wissensch. 

 Anstalt. ix. pt. 2, 124 (1892), not Less., is Gomphrena perennis, L., 

 as is shown by an examination of Ule's no. 1184, collected in Campo 

 near Laguna, Brazil, March, 1889, now in the Gray Herbarium from 

 the herbarium of Dr. Klatt.
