Bab. Low grounds; along rivulets: frequent. Fl* July— Aug*. Fr. Sept. Octo. 



Oas* Pcrsooti doubts whether this is more than a variety of H. caruulewc* but 

 it seems to be sufficiently distinct.

 aub-linear, rather obtuse, narrowed at base, mostly 3-nerved ; corymb

Canadian Hytkricum. 



Root annual ? Stem i> to 13 inches high, herbaceous, slender, simple, or with a 

 few short opposite axillary branches near the summit, slightly 4-angled by the 

 decurrence o( the midrib and margins of the leaves. Leaves about an inch lonoj 

 and 1 to 2 lines wide, nearly linear, minutely pellucid-punctate, often with fascicles 

 of small leaves in the axils. Flower* in an oblong j aniculale corymb] with the 

 branches dichotomous; pedicels rather shorter and stouter than in the preeediiuj 

 (I usually dichotomal), with Mibulate brads at base. Sepals lanceolate, nearly 

 equal. Petals yellow. St yles 3, short. Capsule elongated f conical, mostly dark 

 purple. Seeds numerous, small, cylindrical, longitudinally striate, and minutely 

 rugose, straw-colored. 



Hab. Wet gravelly margins of rivulets: frequent, Fl. August. Fr. Octdber. 



6. H. Saiiotiiua, JMx. Stem erect, obscurely 4-angled, much branch- 

 ed ; leaves minute, subulate, appressed; flowers solitary, tormina] and 

 axillary, subsessile ; petals longer than the calyx ; stamens few ; cap- 

 sule moie than twice as long as the calyx, acute, 1 -celled. JJcck, Bdt.

Broom Hypekicum. Vulgo — Ground Pine. Psit-wccd, Orange-grass, 

 Root annual. Stem 4 to 8 inches high, herbaceous, slender, brachiately and 

 fastigiately branched from near the base*, branches nearly erect, often di- or 

 tri-chotomously sulnlivided, slender, angular or slightly winged by the de< urrent 

 leaves. Leaves 1 to 3 or 4 lines long, subulate, resembling stipules. Flowers sol- 

 itary, sessile or subsessile, alternate in the axils of the small leaves, and terminal, 

 often one dichotomal and pedicellate in the forks of the branches. Scjxtls lance, 

 olate, keeled, nerved or striate, united at base. Petals yellow, lanca-linearj 

 obtuse, longer Mian the calyx. Stajnens 5 to 10. Styles 3. Capsule more than 

 twice as long as the calyx, slender, tapering to a point, mostly dark^purple. Seeds 

 small, oblong, terotc, striate, minutely rugose, pale straw-cob r.

Obs. This seems pretty clearly to belong to the Hypericums,— although I do 

 not find it among the Hypericinta, of De Candolle. The species of this genus are 

 numerous,— more than twenty additonal ones having been enumerated in the U. 

 States ; but the foregoing are all which have heen hitherto detected in Chester 

 County.
