WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 148 
yellow, 13 to 15 mm. long; capsules oblong-ovoid, 4 to 5 mm. long, shorter than 
the sepals. 
Type in the U. S. National Herbarium, no. 562282, collected at Mangas 
Springs, August, 1901, by O. B. Metcalfe. 
The only species with which this can be confused is C. puberulum, but that 
is a short, stout plant with short, thick pedicels and much shorter petals. Our 
plant, too, is simple below, while C. puberulum is invariably branched. 
Evidently related to this and probably the same is Doctor Mearns’s no. 47, 
collected in the Carrizalillo Mountains in 1892. 
ZYGOPHYLLACEAE. 
Kallstroemia laetevirens Thornber, sp. nov. 
Plants semierect, 30 to 50 cm. tall, branched from the base; stems 30 to 60 
em. long, straight, sparingly pubescent throughout, beset above with scattered 
stiff hairs; stipules 5 to 6 mm. long, subulate to linear-lanceolate, hispid; 
leaves 30 to 55 mm. long, the petioles mostly equal to the lowest leaflets; leaf- 
lets 4 to 6 pairs, 9 to 20 mm. long, acutish, oblong to elliptical, glabrous above, 
pubescent with appressed hairs beneath; margins of leaflets prominently ciliate ; 
peduncles in fruit 15 to 40 mm. long, equaling or exceeding the subtending 
leaves, thickened above, appressed-pubescent and with scattered stiff hairs on 
the upper half, in age spreading or reflexed ; sepals subulate to linear-lanceolate, 
6 to 8 mm. long, densely hispid with long, yellowish or tawny hairs; petals 
bright yellow, 7 to 12 mm. long, rather showy, exceeding the sepals; fruit 
finely canescent, the beak 5 to 8 mm. long, columnar, grooved, pubescent, often 
twice the length of the fruit body; nutlets 8 to 10, 3.5 to 4 mm, long, sharply 
tuberculate on the back, faintly reticulate on the faces. 
Type in the U. S. National Herbarium, no. 660420, collected on Hanover 
Mountain, New Mexico, July 31, 1911, by J. M. Holzinger. 
This well marked species differs from K, parviflora in its more erect habit, 
and also in having larger leaflets, leaves, and flowers. It differs from K. 
intermedia in its habit of growth, in its longer peduncles, and in the stems 
being very pilose.
