484 GENTIAN ACE^E. Frasera. 



§ 1. A pair of glands on each division of the corolla : divisions of the calyx linear : 

 flowers in a narrow leafy thyrsus : capsule much flattened contrary to the deep 

 boat-shaped or almost conduplicate vcdves. 



1. F. speciosa, Dougl. Stout, 2 to 5 feet high, very leafy : leaves nervose, in 

 whorls of four to six, not white-margined ; the radical and lowest cauline obovate 

 or oblong, 6 to 1 inches long, above lanceolate and becoming linear : flowers on 

 slender at length strict pedicels in umbel-like pedunculate cymes (or some fascicled 

 in the axils), forming a long virgate thyrsus : corolla greenish-white or barely tinged 

 bluish, conspicuously dark-dotted, not longer than the sepals ; its divisions oval- 

 oblong, bearing a pair of oblong and strongly fringed glands about the middle, 

 crowned at base by a fringe of 8 to 10 long setaceous filaments. — Grisebach in 

 Hook. Fl. ii. 66, t. 153. Tessaranthium radiatum, Kellogg, Proc. Calif. Acad. ii. 

 142, fig. 41. 



Along the eastern parts of the Sierra Nevada (from Tuolumne Co. Brewer) ; thence northward 

 to the interior of Washington Territory, and east to Wyoming and New Mexico. Divisions 

 of the corolla two thirds of an inch long ; the fringe-like crown adnate to their base, and wholly 

 separate from the base of the quite distinct stamens. Style not longer than the ovary : seeds 30 

 or more. 



F. paniculata, Torr. in Pacif. E. Rep. iv. 126, is a New Mexican species of this section, im- 

 perfectly known. 



§ 2. A single gland with a, notched summit on each division of the thickish corolla : 

 divisions of the calyx ovate-lanceolate or br'oader : flowers loosely and ejfusely 

 cymose-panicled. (Mature capside unknown.) 



2. F. Parryi, Ton-. Stout, 2 or 3 feet high : leaves opposite and in threes, 

 lanceolate, with cartilaginous white margins ; the floral and bracts oblong and ovate : 

 divisions of the whitish and dark-dotted corolla ovate, commonly acute, half an 

 inch long ; the fringed gland below its middle, lunately obcordate and with rounded 

 naked base. — Bot. Mex. Bound. 156. 



Southern part of the State, east of San Diego and Los Angeles, Coulter, Wallace, Parry. 

 Ovary apparently flattish parallel with the carpels : ovules rather few. 



F. albomarginata, Watson, Bot. King Exp. 280, of Southern Utah and Nevada, and to he 

 looked for on the southeastern borders of California, is of this section. It is a small species, nar- 

 row leaved ; the divisions of the corolla conspicuously cuspidate ; and the fringed obcordate dark 

 gland on the middle of the petal runs into an adnate scale-like appendage, fixed by its back quite 

 down to the base, the free margins fringed, and united across the base by a small laciniate portion, 

 forming a somewhat hooded base, as in the next. 



§ 3. A single oblong or linear and entire gland reaching from near the base to near 

 the middle of each division of the thinnish (pale blue or lavender-colored) 

 corolla : divisions of the calyx subulate-lanceolate : flowers thrysoid-glomerate : 

 capsule flattened parallel with the valves, few-seeded. 



3. F. nitida, Benth. Glabrous throughout (not minutely and closely puberulent 

 as in F. albicaulis), a foot or more high, slender : leaves only 3 to 5 pairs, linear 

 (2 to 4 inches long, 2 or 3 lines wide, the radical longer and gramineous), white- 

 margined : flowers glomerate in 3 or 4 pairs of short-peduncled or subsessile dense 

 cymes or glomerules, forming a naked and interrupted spicate thyrsus : lobes of the 

 corolla ovate-oblong, becoming lanceolate (3 or 4 lines long) ; the gland with a short 

 indexed fringe all round, which is longer and more laciniate at the hooded base : 

 crown stamineal, consisting of linear or oblong laciniate or nearly entire scales alter- 

 nate and partly connate with the bases of the filaments. — PL Hartw. 322 ; Torr. in 

 Pacif. E. Eep. iv. 126. 



Foot-hills of the Sierra Nevada (Harhvecj, Bigclow, &c), and Sierra Valley (Leminmi, &c), to 

 Oregon, Lyall, Ncvivs. Probably this may be only a variety of F. albicaulis of Oregon (Hook. 

 Fl. t. 154), extending as it does into the range of that species. The crown appears to be different, 

 but its characters are variable.
