Hypericum. HYPERICACE^. 285 



terete, with a slightly winged rhaphe. — Spec. ii. 783; Maxim. PI. Nov. Asiat. iv. 162. 

 H. pyramidatum, Ait. Kew. iii. 103; Torr. & Gray, Fl. i. 1.58. H. asci/roides, Willtl Spec, 

 iii. 1443 ; Chois. in DC. Prodr. i. 545. H. mucrocarpum, Michx. Fl. ii. 82. — In the Atlantic 

 region as far south as Connecticut and Pennsylvania, and extending westward to Missouri, 

 Minnesota, and the Winnipeg Valley, and doubtless farther northwest. (Throughout N. E. 

 Asia, and in Eu.) 



•4— -1— Styles united into a long sharp beak, finally becoming distinct ; stigmas minute, not 

 capitate : more or less shrubby plants. 



++ Styles usually 5 and capsule 5-celled : bushy shrubs with crowded leaves. 

 H. Kalmianum, L. A foot or two high : leaves linear to oblanceolate, tapering at base, 

 1 to 2 inches long, 2 to 4 lines wide, pellucid-punctate with round dots, glaucous beneath : 

 cymes few-flowered : sepals lanceolate to oval, half as long as the petals : capsule ovate, 

 about 3 lines long, often somewhat lobed ; seeds abruptly and minutely pointed. — Spec. ii. 

 783; Torr. Fl. N. Y. i. 86, t. 13; Torr. & Gray, Fl. i. 158. — Rocky and sandy shores, 

 Canada, Niagara Falls, and about the Great Lakes. The capsules may be 4- or 6-celled, but 

 the 5-celled condition is by far the most common. 



H. lobocarpum, Gattinger. A shrub 5 to 7 feet high, with upright branches : leaves 

 linear-lanceolate to narrowly oblong, 1 to 3 inches long, 3 to 9 lines broad, with smaller ones 

 in axillary fascicles : flowers numerous, smaller than in the last (usually resembling those of 

 H. densiflorum) : sepals linear-lanceolate, not foliaceous : capsule 2 to 3 lines long, lanceo- 

 late and tapering to tlie long strong beak, completely 5-celled and deeply 5-lobed, in most 

 cases the five carpels almost distinct, and at maturity falling away separately from the 

 central axis. — Bot. Gaz. xi. 275. — Oak barrens of Middle and Western Tennessee, Gat- 

 tinger, Western Mississippi, Steivart, and Southern Louisiana, Daves, and probably through- 

 out the Lower Mississippi region. The type specimens were growing in a swampy region 

 difficult to penetrate. In size and general habit the plant closely resembles H. densijiornm, 

 with perhaps even denser flower clusters ; but the flowers may become almost as large as 

 those of H. Kalmianum and H. prolijicum, which latter species it very closely resembles as 

 to its leaves. It is impossible to distinguish the species from forms of H. prolijicum and 

 H. densiflorum in the absence of capsules. Certain forms also resemble H. fasciculatum in 

 their narrow, rigid, and very revolute leaves, and in tiie axillary fascicles. 



++ ++ Styles usually 3 and capsules completely 3-celled : branching shrubs. 



H. prolificum, L. Leaves linear-lanceolate to narrowly oblong, narrowed at base, mostly 

 obtuse and mucronulate, 1 to 3 inches long, 3 to 9 lines broad, with axillary fascicles of 

 smaller ones : flowers numerous, | to 1 inch broad : sepals unequal, foliaceous, lanceolate to 

 ovate, mucronate, much shorter than the petals : capsule lanceolate to ovate, 4 to 6 lines 

 long. — Mant. 106; Chois. in DC. Prodr. i. 547; Torr. & Gray, Fl. i. 159, excl. var. y. 

 H. rosmarini folium, Torr. & Gray, 1. c, not Lam. Myriandra ledifolia, Spach, 1. c. 365. — 

 From New Jersey to Georgia, Alabama, Arkansas, Missouri, and Minnesota. The leaves 

 are exceedingly variable in size, often resembling those of the next species, especially at 

 the south, but the flowers and capsules are much larger and much fewer. Flowers with 

 four styles are occasionally found, making the separation from the last two species difficult. 



H. densiflorum, Pursh. More shrubby and taller, sometimes 5 to 6 feet high, much 

 more branching : leaves more crowded, narrower and shorter : flowers much more luimerous 

 and smaller : sepals smaller, not foliaceous : capsule ovate, 2 to 3 lines long. — Fl. ii. 376 ; 

 Chois. 1. c. H. galioides, Pursh, 1. c, not Lam. ? H. prolificum, var. y, Torr. & Gray, 1. c. 

 H. prolificum., var. densifiorum. Gray, Man. ed. 5, 84. Mi/ririndra spa'thidata, Spach, 1. c. — 

 From the pine barrens of New Jersey to Florida, Tennessee, Arkansas, and Texas. 

 Occasional forms with large leaves closely simulate the last species, but the flowers and 

 capsules can be distinguished easily. Four and even five styles sometimes occur, but tlie 

 flowers upon any plant are prevailingly 3-styled, and even the 5-styled capsules are distinct 

 from those of //. lobocarpum, which are narrow and relatively long, tapering from the base 

 to the prominent beak, besides being very deeply lobed. 



H. Buckleii, M. A. Curtis. Low, ^ to 1 foot high, widely branching from the base : 

 leaves oblong, obtuse, narrowed at base, ^ to 1 inch long, 2 to 4 lines broad, paler beneath
