484 GENTIANACE.E. Frasera. 



§ 1. ^ pair of glands on each division of the corolla : divisions of the calxjx linear : 

 jiowers in a narrow leafy thyrsus : ca23side much flattened contrary to the deep 

 boat-shaped or almost conduplicate valves. 



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

 whorls of four to six, aio't white-margined ; the radical and lowest cauline ohovate 

 or oblong, 6 to 10 inches long, above lanceolate and becoming linear: flowers on 

 slender at length strict pedicels in umbel-Hke iDedunculate 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 luiddle, 

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

 Hook. Fl. ii. G6, t. 153. Tessaranthinm radiatum, Kellogg, Proc. Calif Acad. ii. 

 142, fig. 41. 



Along the eastern parts of the Sierra Nevada (from Tuoliamne Co. Brcivcr) ; thence northward 

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

 of tlie 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. R. 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 broader : flowers loosely and effusely 

 cymose-panicled. {Mature capsule unknown.) 



2. F. Parryi, Torr. 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 Ion"- ; the fringed gland below its middle, Innately 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 tew. 



F ALBOMARGiNATA, Watson, Bot. King Exp. 280, of Southern Utah and Nevada, and to be 

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

 row leave.l ; 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. ^ 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 ccdyx subulate-lanceolate : floivers thrysoid-glomerate : 

 capstde 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 

 cym'es 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 

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

 crown stamineal, con.sisting of linear or oblong laciniate or nearly entire scales alter- 

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

 Pacif. P. Pep.'iv. 126. 



Foot-hills of the Sierra Nevada (Harttveg, Bigclow, &c.), and Sierra Valley (Lemmon, &c ), to 

 nre<ron, Lyall, Nevius. 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 ditlerent, 

 but its characters are variable.
