136 EPILOBIACE.E. 



lobed or cleft. Stamens normally 8, but those opposite the petals often 

 sterile or rudimentary, or sometimes wanting; anthers oblong or linear, 

 fixed by the base. Ovary 4-celled; style elongated; stigma with 4 broad 

 spreading lobes. Capsule linear, attenuate above, coriaceous, straight 

 or somewhat curved, 4-angled, 4-celled, 4-valved to the middle. Seeds 

 angled or margined. 



* Calyx-tube elongated and almost filiform ; stamens 4 only. 



1. C. conciima (F. & M.), Greene. Simple, or with a few subcorym- 

 bose branches, 1 2 ft. high, glabrous or puberulent: leaves ovate, 

 entire: calyx- tube almost filiform, 1 in. long: corolla regular; petals 

 3^ % in. long, cuneate-obovate, 3-lobed, the middle lobe broadest, little 

 longer than the others: filaments subulate; anthers recurved after dehis- 

 cence, somewhat villous: stigma subpeltate, the lobes short, rounded: 

 capsule subcylindrical, in maturity obscurely quadrangular, acutish. 

 Coast Range at considerable elevations. May, June. 



2. C. grandiflora (F. M.), Greene. Near the preceding, but dif- 

 fusely branching from the base: corolla larger, irregular, the 3 upper 

 petals approximate, ascending, the lower one remote from these and 

 declined, the middle lobe of each attenuate to a claw and far surpassing 

 the others. Very common in the Mt. Diablo Range, perhaps identical 

 with the preceding. 



3. C. Breweri (Gray), Greene. Glabrous,! 2ft. high: leaves lanceo- 

 late, entire, short-petioled: calyx-tube slender, more than 1 in. long, 

 abruptly dilated at base: corolla irregular; petals round-obcordate, with 

 a linear-spatulate middle lobe proceeding from the deep, or rather shallow 

 sinus and far exceeding the others: filaments clavate: anthers densely 

 white-villous along the sutures, erect after dehiscence as before: capsule 

 sessile, 1 in. long, curving away from the stem: seeds large, tuberculate, 

 conspicuously winged. On Mt. Hamilton. 



* * Calyx-tube obconic; petals never 3-lobed; stamens 8, all perfect. 



4. C. elegans, Dougl. Glabrous or puberulent, reddish and glaucous, 

 erect, 16 ft. high, simple or somewhat branching, stout and rigid: 

 leaves broadly ovate to linear, repand-dentate: petals entire, the rhom- 

 boidal limb about equalling the linear claw: filaments with a densely 

 hairy scale on each side at base: capsule %% i n - long, stout, sessile, 

 4-angled, somewhat curved, often hairy. On open or half-shaded hill- 

 sides, very common. 



5. C. rhomboidea, Dougl. Puberulent or glabrous, 13 ft. high, 

 rather slender: leaves thin, entire, oblong-lanceolate to -ovate, 1 2 in. 

 long: petals with rhomboidal limb and short broad claw which is often 

 broadly toothed : filaments with hairy scales at base: capsules pedicellate, 

 812 lines long, 4-angled, glabrous, curved near the base. Of wider 

 range than the last; equally common.
