448 GENTIANACE.E FRASERA 



or nearly entire. Capsule coriaceous, commonly flattened ; the 

 placentae or ecUes of the valves not intruded. Seeds compara- 

 tively few, compressed, commonly smooth and margined. 



* Leaves marginless : sepals narrow, almost as long as the corolla : 

 corolla with a single round gland upon each lobe; no crown at base: 

 capsule strongly flattened parallel with the valves : seeds orbicular, 

 wing margined : stem large and stout. 



F. thyrsiflora Hook. Kew Jour. Bot. Hi, 288. " Stems 2 or 3 feet 

 high: leaves in pairs 'or threes, oblong or spatulate-obovate, the cauline 

 3 or 4 inches long : flowers in a dense interrupted thyrsus : sepals subulate- 

 linear ( 4 lines long ) : lobes of the pale blue corolla ovate-oblong, thin, 

 bearing the gland near the base : style short and conical, in some flowers 

 hardly any. Idaho and interior of Oregon on the tributaries of the Colum- 

 bia. " 



* * Leaves not margined: sepals linear, equalling the corolla: a 

 pair of oblong glands on each corolla-lobe and a separate crown below 

 them : capsule compressed contrary to the almost conduplicate valves : 

 seeds oblong, flat margined. 



F. speciosa Dpugl. Griseb. Gent. 329. Stem stout, 2-5 feet high, 

 very leafy : leaves in fours and sixes, nervose ; the radical and lowest cauline 

 obovate or oblong, 6-10 inches long, the upper lanceolate and at length 

 linear: flowers very numerous in a long leafy thyrsus: the peduncles and 

 slender pedicels at length strict: lobes of the greenish-white or barely 

 bluish and dark-dotted corolla oblong, acutish, half inch long, bearing the 

 pair of contiguous and densely long-fringed glands about the middle, and 

 a distant transversely inserted and setaceously multifid scale-like crown 

 near the base, usually some minute setsea between the bases of the fila- 

 ments : style subulate, shorter than the ovary. In the mountains, eastern 

 Oregon to California, Wyoming and New Mexico. 



* * * Leaves with cartilaginous white irargins, thickish, lanceo'ate 

 or linear and grass-like, merely opposite, the cauline only 3-5 pairs: 

 inflorescence a virgate interrupted thyrsus of 3-7 pairs of sessile or 

 short-peduncled dense cymes, forming a series of glomerate clusters : 

 pedicels very short : sepals subulate-lanceolate, about equalling the 

 oblong or ovate lobes of the blue corolla: fringed glands solitary, elon- 

 gated, extending from the base of the lobe to near the middle, saccate 

 and with a longer and coarser fringe at base : crown gtaminal, consist- 

 ing of a conspicuously laciniately parted or nearly entire scale between 

 the filaments : style slender, twice the length of the ovary: capsule 

 compressed parallel with the flat or flattish valves, few-seeded : seeds 

 as far as known flat, smooth, acute-angled. 



F. nitida Benth. PI. Hartw. 322. Completely glabrous : stems slender, 

 1-2 feet high, simple: leaves linear-lanceolate; the radical ones 6-8 inches 

 long; those subtending the upper flower clusters reduced to small bracts: 

 sepals linear- lanceolate, acuminate,, scarcely margined with white, entire: 

 corolla blue, sometimes spotted with greenish dots, the lobes barely acute, 

 bearing an elongated-oblong obtuse gland: thin scales between the fila- 

 ments ovate or oblong-linear, entire or sparingly laciniate, longer than the 

 ovary. Common from Brit. Columbia to California, east of the Cascade 

 Mountains. 



F. Cusickii Gray Proc. Am. Acad. xxii, 310. Glabrous : stems slen- 

 der, 2-s inches hig'i, but little longer than the radical leaves: thyrsus 

 either of s in pie glomerules or interrupted spiciform : corolla large ; its lobes 

 nearly halfinch long, oval, obtuse: scales between the filaments large, or- 

 bicular, concave, nearly entire, surpassing the ovary. Hillsides ot the
