Northern California, Dotislas ! Oregon, Mr. lUinie ! — Petals about 

 half an ineh in length. Anthers oblong. Style about the length of the 

 longer stamens. 



* * * • Lobes of the stigma obovate, sJiurt : capsule distinctly pedicellate : 

 seeds ascending. 



41. CE. Bnllfe (Spach): stem and branches virgate, nearly glabrous; 

 leaves lanceolate or linear-lanceolate, much attenuate at the base and apex, 

 acute, deeply denticidate, petioled, nearly glabrous ; segments of the calyx 

 much longer than the obconic tube, and rather shorter than the petals ; 

 ovary scarcely longer than the stipe. Spach, Onagr. p. 73, (under Go- 

 detia.) 



Southern California, BoUa, ex Spach.— Stem 2 feet long. Petals 12-15 

 lines long, purple. Style a little exceeding the anthers of the longer 

 stamens. Stamens more than half the length of the petals: anthers all 

 longer than the filaments. Spac]i. 



§ 5. Stigma uith 4 very short lobes : tube of the calyx infnndibuliform, as 

 long as the ovary ; the segments rather erect : petals ohovate-cuneiform, 

 2-lobed, erect-spreading: stamens erect: the filaments (fdiform) opposite 

 the petals much shorter and usually inserted loiver cloivn: anthers mostly 

 short, fixed below the middle : capsules oblong or cylindrical, short, sessile, 

 nearly membranaceous, commonly uith a large and thick A-angled pla- 

 centa : seeds feio (4-6 in each cell), in a single series, ascending, not 

 appendiculate ; the testa somewhat crustaceous : stems annual : flowers 

 {rather small) diurnal, purple or rose-color, usually 2-5 together in the 

 axils of the floral bract-like leaves. — Boisduvalia, Spach. 



42. CE. densiflora (Lindl.) : somewhat canescently pubescent ; leaves 

 lanceolate or linear-lanceolate, acute, denticulate; the floral leaves crowded, 

 ovate or ovate-lanceolate, acuminate, closely sessile, mostly entire ; tube of 

 the calyx obconic, a little longer tlian the ovary, scarcely the length of the 

 triangular-lanceolate segments ; alternate stamens much shorter ; anthers 

 elliptical ; placenta large, acutely 4-angled ; the angles reaching to the 

 valves. — LindL bot. reg. t. 1593. Boisduvalia Douglasii, Spach ! Onagr.

Oregon, Douglas ! Mr. Tolmic ! On the Wahlamet and Wallawallah, 

 Nuttail ! — A variable plant, as well in its native situations as in cultivation. 

 The valves fall away, leaving the dissepiments wholly united with the thick 

 placenta, in depressions of which the ovules are partly imbedded. 



43. CE. glabella (Nutt. ! mss.) : " glabrous ; leaves lanceolate, acumi- 

 nate, serrulate ; the floral ones ovate-lanceolate, nearly similar ; capsules 

 slightly hairy, cylindrical, striated, the valves septiferous ; seeds oblong."
