326 PROCEEDINGS OP THE AMERICAN ACADEMY 



hooded keel ; petals broadly oblong ; crest broad, very unequally 

 2-lobed on each side : capsule glabrous, oblong, Ih lines long, slightly 

 inequilateral: caruncle of two linear lobes two-thirds of the length of 

 the pubescent seed. — On Caracol Mountains, Coahuila (2013). Very 

 nearly allied to P. scoparia. The crest is a broad triangular lamina 

 on each side of the median line, to which it is attached, with a narrow 

 lobe on the outer side. 



PoLYGALA SEMiALATA. Glabrous ; stems numerous, very slender, 

 angled, from an apparently biennial root, 3 to G inches high : leaves 

 scattered, linear, acute at each end, 2 or 3 lines long : racemes termi- 

 nal, very slender and open (1 to 3 inches long), the very small 

 whitish flowers (little more than half a line long) nearly sessile and 

 soon pendulous; wings broadly spatulate; petals truncate, nearly 

 equallmg the fimbriately crested keel : capsule similar to that of 

 P. hemipterocarpa, but only 2 lines long, and the dehiscing cell more 

 narrowly winged. — At Monterey, Nuevo Leon (67). With P. hemi- 

 pterocarpa forming a section marked by the curious unequally devel- 

 oped fruit, one cell indehiscent and filled by the seed, the other 

 doubly wing-margined, dehiscing between the wings, and at length 

 unfolding. 



Krameria cytisoides, Cav. {K. cinerea, Schauer.) In moun- 

 tains east of Saltillo (59); 1043 Parry & Palmer. 



Krameria canescens. Gray. At Soledad, Coahuila (61). 



Krameria pauciflora, DC. In the mountains east of Saltillo, 

 single specimens ; 38 Parry & Palmer. Distinguished from K. secun- 

 diflora, DC. {K. lanceolata, Torr.), as it is understood, by the uni- 

 formly shorter naiTowly lanceolate leaves (3 or 4 lines long), and 

 by the retrorse barbs along the more slender spines of the fruit. 



Krameria ramosissima. Shrubby and divaricately much branched, 

 a foot or two high, canescent: leaves linear-lanceolate, 1 or 2 (some- 

 times 3) lines long, often fascicled in the axils : flowers " light maroon " : 

 fruit ovate, silky-pubescent, with slender very acute naked spines about 

 half a line long. — K. parvifolia, var. ramosissima, Gray, PI. Wright. 

 1. 41. On mountains near Saltillo (62) ; also on the Rio Grande 

 (Wright), at Camargo (Gregg), and in Nuevo Leon (Berlandier). 



Frankenia grandifolia, Cham. & Schlecht. At San Lorenzo 

 de Laguna, Coahuila (60). 



Silene laciniata, Cav., var. with ovate leaves. (S. Greggii, 

 Gray.) In the Sierra Madre, south of Saltillo (71). The form with 

 linear leaves, at the other extreme, is the more common ; in the San 

 Miguelito Mountains (609 Schaffner) ; 46 Parry &, Palmer.
