HYPERICACEAE 789 



above : leaf-blades leathery, narrowly oblong to lanceolate, 2-6 cm. long, with smaller ones 

 often clustered in the axils, conspicuously nerved, sessile : flowers in terminal corymbose 

 cymes : sepals lanceolate or ovate-lanceolate, 4-6 mm. long, acute: corolla yellow, 1-1.5 

 cm. broad : petals cuneate : capsules ovoid, the body 5-6 mm. long, slender-beaked.

14. Hypericum glomeratum Small. Perennial, shrubby. Stems branching, 3-10 

 dm. tall, with somewhat scaly bark, the foliage glabrous : leaf -blades narrowly oblong to 

 linear-oblong or nearly linear, 2-4 cm. long or those clustered in the axils shorter, more 

 or less distinctly apiculate, often somewhat revolute, paler beneath than above, sessile : 

 flowers in dense cymes terminating the branchlets : pedicels 2-8 mm. long : buds ovoid, 

 acutish : sepals rather foliaceous, narrowly oblong to linear-oblong, 5-6 mm. long, acutish, 

 strongly nerved, reflexed at maturity : petals bright yellow, cuneate-spatulate, fully 1 cm. 

 long, undulate at the apex : stamens numerous : capsules densely clustered, oblong-ovoid, 

 5-6 mm. high, slightly lobed, the placentae only slightly intruded.

15. Hypericum interior Small. Perennial, shrubby. Stems several dm. tall, much 

 branched, the branches sharply angled, glabrous : leaf-blades narrowly oblanceolate to 

 linear-oblanceolate, 1-3 cm. long, acute, slightly revolute, pale beneath, narrowed into 

 slender petioles : panicles many-flowered : sepals linear or narrowly oblong, 3-4 mm. 

 long, acute, rather rigid, more or less spreading at maturity : corolla yellow, about 1 cm. 

 broad : petals cuneate : capsules conic-ovoid, 5-6 mm. long. 



Along streams, Texas. Summer. 



16. Hypericum ambiguum Ell. Perennial, shrubby. Stems 0.5-1.5 m. tall, widely 

 branched, with a scaly bark : leaf -blades linear-oblong or spatulate, 1-2.5 cm. long, acute 

 or apiculate, flat or slightly revolute, narrowed into short petiole-like bases : flowers few, 

 in axillary cymes disposed in narrow panicles : bracts similar to the leaves but much 

 smaller : sepals linear or slightly broadened upward, 3-5 mm. long, acute : corolla yellow, 

 15-18 mm. broad : petals obliquely obovate or cuneate, almost laterally apiculate : capsules 

 almost conic, 5-6 mm. high, surpassing the sepals. 



In and about river swamps, South Carolina to Florida and Alabama. Spring and summer. 



17. Hypericum galioicles Lam. Perennial, shrubby. Stems 3-8 dm. high or taller, 

 glabrous : leaf-blades narrowly linear or slightly broadened upward, 0.5-1.5 cm. long, 

 acute, slightly revolute, each tapering into a very short petiole-like base or sessile : flowers 

 solitary or in axillary cymes forming narrow panicles : sepals linear or linear-spatulate, 3-4 

 mm. long, more or less revolute : corolla yellow, about 1.5 cm. broad: petals cuneately 

 narrowed, obliquely or almost laterally pointed : capsules conic, 5-6 mm. long, acute. 



In low pine lands, Florida and Alabama. Summer and fall. 



18. Hypericum fasciculatum Lam. Perennial, shrubby. Stems 1-5 m. tall, with 

 numerous sharply angled branchlets : leaves numerous, a bunch usually clustered in the 

 axils of the larger ones ; blades leathery, linear-filiform, 1-2 cm. long, or shorter in the 

 clusters, acutish, revolute, sessile : flowers in loose narrow panicles, or at first rather 

 corymbose : sepals linear, 3-4 mm. long, about 1 cm. wide : petals bright yellow, ob- 

 liquely apiculate : capsules ovoid or conic-ovoid, 4-5 mm. long, acute. 



In wet sandy pine lands, North Carolina to Florida and Texas. Spring and summer. 



19. Hypericum aspalathoides Willd. Perennial, shrubby. Stems nearly simple, 

 or much branched, 2-8 dm. tall, with sharply angled branchlets : leaves very numerous, 

 clusters of small ones borne in the axils of the large ; blades linear-subulate or linear-fili- 

 form, 5-8 mm. long, or shorter in the clusters, obtuse, revolute, sessile : flowers several, in 

 terminal corymbose cymes, slender-pedicelled : sepals linear, 3-4 mm. long, resembling the 

 small leaves : corolla bright yellow, about 1-5 cm. broad : petals oblique, not apiculate : 

 capsules conic, 5-7 mm. long, acuminate. 



In pine lands and open places, North Carolina to Florida and Louisiana. Spring and summer. 



20. Hypericum myrtifolium Lam. Perennial, shrubby. Stems branching, 3-10 

 dm. tall, erect or creeping : leaves persistent, leathery ; blades ovate to oblong-ovate, or 

 ovate-lanceolate or rarely nearly oblong, 1-3 cm. long, obtuse at the apex or rarely acute, 

 often slightly revolute, clasping : bracts like the leaves, but smaller, sometimes narrower : 

 flowers showy, sometimes very numerous : sepals foliaceous, ovate, 5-8 mm. long, acute or 

 acutish, united at the base : corolla golden yellow, about 2 cm. broad : stamens numerous : 

 capsules pyramidal-ovoid, incompletely 3-celled or rarely 4-celled, 5-6 mm. high, 3-4- 

 lobed or 3-4-sided. 



In sandy pine lands, especially in wet soil, South Carolina to Florida and Alabama. Summer.
