 ly translucent-glandular-dotted, 4.5-8 mm. long, 1.5-6 mm. wide, 

 on petioles 0.5 mm. long. Racemes axillary, very short, 1-2- 

 flowered. Flowers purple, 6-7.5 mm. long. Sepals oblong-ovate, 

 obtuse, ciliate and puberulous, 1.2-1.5 mm. long, the upper often 

 subpersistent. Wings spatulate-obovate, long-cuneate at base, 

 rounded at apex, sparsely ciliate, purple, 7.5 mm. long, 3.7 mm. 

 wide. Keel 3-lobed, the lateral lobes broad and rounded, 4.5 mm. 

 long. Upper petals oblong-obovate, rounded at apex, 5 mm. long. 

 Staminal tube ciliolate at base. Capsule " elliptic, deeply emar- 

 ginate, slightly pilose, dotted with whitish glands." Seed " oblong, 

 clothed with appressed hairs." Aril " galeiform, equitant, with 

 very short lobes, 3-4 times shorter than the seed." HBK. Nov.

 P. Greggii Wats.! Proc. Am. Acad. xvii. 325 (1882). Nuevo 

 Leon: west of Cerralbo, 29 May 1847, Gregg (type of P. Greggii: 

 G). San Luis Potosi: dry hills, Micos, 1 Aug. 1891, Pringle 

 4006 (G) . The flowers are described by Watson, presumably 

 from Gregg's label, as white, but as some of those in Pringle 4006 

 are manifestly purple, while others have faded to the same dull 

 whitish hue as in Gregg's plant, I have taken the normal color of 

 the fresh flower as purple.
