1-3 cm. long, obtuse, black-dotted beneath at least along the margins; flowers in 

 cymes; sepals 2-5 mm. long, ovate, black-dotted at least on margins, obtuse to 

 acuminate; petals 7-14 mm. long, with black dots or glands on margins; stamens 

 separate or nearly so, numerous (over 20); capsule about 8 mm. long. 



Along streams, in seepage or in wet meadows in N.M. (Catron, Colfax, Lincoln, 

 Otero, San Miguel. Sandoval and Taos cos.) and Ariz. (Apache, Coconino, Navajo 

 and Pima cos.), June-Sept.; Wyo. to N.M., Ariz., s. Calif, and Mex. 



3. Hypericum punctatum Lam. 



Plant erect, to about 1 m. high, conspicuously marked with black and pellucid 

 dots, the main stems mostly simple and with few to no branches below the inflo- 

 rescence; leaves sessile or somewhat clasping at the base, typically oblong to oblong- 

 elliptic but sometimes narrowly ovate-oblong, to 7 cm. long and 2 cm. wide, 

 rounded to obtuse or even retuse at apex; flowers crowded in small clusters that 

 terminate short branches at summit of plant; sepals heavily dotted and lined with 

 black, ovate-oblong to triangular-lanceolate, obtuse to subacute at apex, 2.5-4 mm. 

 long; petals pale-yellow, copiously black-dotted, 4-7.5 mm. long; styles 2-4 mm. 

 long, mostly persistent; capsules ovoid, 4-6 mm. long, conspicuously beset with 

 amber-colored glands; seeds less than 1 mm. long. 



On open-wooded hills and on edge of woods and fields and low wet areas, in e. 

 Okla. (Haskell, LeFlore, McCurtain and Ottawa cos.) and n.-cen. and n.e. Tex., 

 June-July; from Fla. to Tex., n. to Que. and Minn. 



4. Hypericum densiflorum Pursh. Fig. 527. 



Shrub to 2 m. high, much-branched above, the upright branches slender; leaves 

 linear to linear-elliptic or oblanceolate, obtuse-apiculate to acute at apex, tapering 

 at base to a short petiole, to 75 mm. long and 15 mm. wide, with smaller leaves in 

 axillary fascicles; flowers numerous in crowded compound cymes; sepals firm, 

 linear-lanceolate to elliptic, 2-5 mm. long; styles 3 to 5, persistent, somewhat con- 

 nate at base, either completely separate from the beginning or tardily separating, 

 2-3 mm. long; capsules lance-ovoid to slender-conic, more or less deeply lobed or 

 sulcate, the body to 6 mm. long and 3 mm. thick, composed of 3 to 5 distinct 

 carpels; seeds reddish-brown, 0.8-1.3 mm. long. 



On pinewood slopes and in and on the edge of swamps, bogs and marshes, and 

 along wooded streams, in s.e. Okla. (McCurtain and Pushmataha cos.) and in s.e. 

 Tex., May-Aug.; from Fla. to Tex., n. to N.Y., N.J., W.Va., s. Ind. and s. Mo. 



The usually 4 or 5 styles and the deeply lobed capsules of the more southern var. 

 lohocarpum (Gatt.) Svens. {H. lobocarpum Gatt.) set it apart from var. densi- 

 florum and H. prolificum. The leaves are also usually larger than those of var. 

 densiflorum whose leaves are usually less than 5 cm. long and 8 mm. wide. In our 

 material, where there is a preponderance of flowers with 4 or 5 styles these are 

 early separated in flower. However, in var. densiflorum and in those plants having 

 only a few flowers with 4 or 5 styles, the styles often remain tightly coherent or 

 even twisted together until the fruit is well-developed. 



5. Hypericum prolificum L. Shrubby St. John's-wort. 



Rather coarse diffusely branched shrub to 2 m. high, with sharply 2-edged twigs; 

 leaves typically narrowly oblong, 3-7.5 cm. long and to 15 mm. wide, narrowed at 

 base to a short petiole, obtuse at apex; cymes both terminal and in the upper axils, 

 contracted, the inflorescence thus interruptedly cylindric; sepals elliptic, 5-7 mm. 

 long; petals obovate, 7-10 mm. long; styles 3 (rarely 4); capsules lance-ovoid to 

 subcylindric-conic, 3-carpellate, 8-15 mm. long, 3-5 mm. thick. H. spathulatum 

 (Spach) Steud.
