448 GENTIANACEAE frasera 



a distinct and often slender persistent style : stigma small, 3-lobed 

 or nearly entire. Capsule coriaceous, commonly flattened; the 

 placentae or edges 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 flatterted parallel with the valves : seeds orbicular, 

 wing margined : stem large and stout. 



F. thyrsiflora Hook. Kew Jour. Bot. iii, 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 subu- 

 late-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 Columbia." 



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

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

 low them: capsule compressed contrary to the almost conduplicate 

 valves : seeds oblong, flat margined. 



F. speciosa Dougl. Griseb. Gent. 339. 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 mid- 

 dle, and a distant transversely inserted and setaceously multifid scale- 

 like crown near the base, usually some minute setse between the 

 bases of the filaments: style subulate, shorter than the ovary. In the 

 mountains, eastern Oregon to California, Wyoming and New Mejcico. 



* * * Leaves with cartilaginous white margins, thickish, lanceolate 

 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 staminal, con- 

 sisting of a conspicuously laciniately parted or nearly entire scale be- 

 tween the filaments : style slender, twice the length of the ovary : cap- 

 sule 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 slen- 

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

 inches long; those subtending the upper flower cluster 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 be- 

 tween the filaments 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, 2-8 inches high, but little longer than the radical leaves: thyrsus 

 either of simple glomerules or interrupted spiciform: corolla large; its
