ones 3-5-lobed, the middle lobe largest, oblong' to triangular in 



outline, obtuse, lateral lobes rounded, sinuses shallow, irregularly 

 crenate-dentate, veins prominent and very scurfy ; petioles 1-3 cm. 

 long, ascending : flowers in clusters in the axils of the reduced 

 upper leaves forming an elongated leafy panicle ; peduncles 1-3 

 cm. long, pedicels 3-10 mm. long; involucral bracts 3, linear- 

 subulate : calyx-tube campanulate, persistent, 2-4 mm. long, limb 

 of 5 ovate acute segments of same length as tube : petals obovate, 

 10-14 mm - long, 10 mm. broad, orange-vermilion (drying rose 

 colored), on some plants a light pink : staminal tube antheriferous 

 only at the top: carpels 12-15, elliptical-oblong, reticulate on 

 sides near the base, smooth above, cuspidate, cusp 1-2 mm. long ; 

 seeds usually two in each cell, finely pubescent, slightly flattened. 



Collected at Mesilla, July 14, where it is a common fence-row 

 and ditch-bank weed. Altitude 3900 feet, no. 2. 



This has been collected by most of the collectors in the south- 

 west, for it is a common plant in that region, but has generally 

 been referred to 5. cuspidate, (Gray) Britton {S. angustifolia var. 

 cuspidate Gray). The most typical specimen of it in Columbia 

 Herbarium has " 5. angustifolia var. cuspidate passing to Fendleri"

upon the sheet in Dr. Gray's handwriting. In the field it is easily 

 separable from either of these species. S. Fcndlcri is only about 

 half the size of either of the others, being rarely over 7 dm. high, 

 and has deeply 5-lobed leaves. S. cuspidate has much the size 

 and habit of S. lobata, but its upper leaves are narrowly oblong 

 and not lobed and only the lowest leaves are obscurely 3-lobed, 

 while all are more or less folded together along the midrib, the 

 flowers are slightly more orange-colored, and although I watched 

 carefully for color variation in the thousands of plants passed dur- 

 mg the summer, I saw none whatever. 



v Gaura Neo-Mexicana. 



Several curved ascending stems from a ligneous root, each 

 branching above into several erect to ascending virgate branches 

 bearing terminal spikes ; bark brown and shreddy below ; whole 

 plant villous with hairs of various lengths, spreading hispidulous 

 on the lower portion of the stem, some of the hairs curved and 

 subappressed upon the middle and upper parts, mostly so on the 

 leaves, becoming finely viscid glandular and spreading upon th< 

 '"florescence : leaves lanceolate, 5-10 cm. long, 8-16 mm. wide, 

 acute, decurrent, subsessile, subentire to slightly sinuate with a few
