P. viscdsA, DC, of the East Indies, one of the ambiguous members of this genus, with 

 hardly any claws to the (yellow) petals, and short stamens, is an occasional ballast-weed at 

 eastern ports. The genuine members of the genus are N. American and Mexican. 



* Leaflets and capsules linear : habit of Cristatella : flowers white. 



P. tenuifolia, Torr. & Gray. Slender, freely branching, viscidulous-puberulent, but the 

 (3) filiform-linear leaflets nearly smooth and glabrous : petals short-unguiculate, oval or 

 ovate, unequal, larger 2 lines long, about the length of the 9 to 11 lanequal stamens : capsule 

 2 inches long, terete, minutely but strongly reticulated, short-stipitate : seeds smooth. — Fl.

* * Leaflets 3, oblong-lanceolate to obovate : upper bracts of simple small leaves : capsules 

 turgid, lanceolate-oblong : petals white or cream-color, sometimes changing to pink, 

 slender-unguiculate, emarginate : filaments 12 to 24, purple. 



P. graveolens, Raf. llaceme leafy or short : petals 2 or 3 lines long, little surpassed by 

 the stamens : style only half the length of the ovary : capsule contracted at base into a 

 short stipe : seeds smooth or nearly so. — Am. Jour. Sci. i. 379, Jour. Phys. 1. c, & Med.

P. trachysperma, Torr. & Gray. Mostly larger : petals 4 or 5 lines long : capillary 

 purple filaments at length 5 or 6 lines long : style as long as the ovary or longer : capsule 

 contracted more or less at base but not stipitate : seeds at maturity usually but not always 

 roughish or verrucose. — Fl. i. 669 ; Gray, PI. Fendl. 10, & Gen. 111. i. 182, t. 79 ; Brew. &

P. uniglandulosa, DC. Petals (with tlieir filiform claws) over half inch long: capilhu-y 

 filaments 1| to 2 inches long: style long and capillary: capsule commonly 3 or 4 inclics 

 long, comparatively narrow, short-.stipitate ; valves with midnerve extending well toward 

 the summit; seeds smooth. — Prodr. i. 242 ; Gray, PI. Wright, i. 10; Wats. 1. c. Cleome

1 Baron F. von Mueller and the Kew botanists have recently advocated \initing this genus with 

 Cleome, from which, when extended to include foreign species, it is not separable xipon very satisfac- 

 tory or constant characters.
