Lobelia. LOBELIACE^. 3 



N. ramosissimus, Nutt. Glabrous, except the minutely pubescent tuft of radical 

 leaves : calyx 5-clef t ; its tube turbinate, adnate to the lower third of the ovary and round- 

 ish capsule, which does not exceed the rather unequal lobes: corolla short (a line long), 

 soon separating into 3 or 5 parts or petals : filaments monadelphous above : seeds oblong- 

 oval. —PI. Gamb. (Trans. Am. Phil. Soc. n. ser. viii.),254; Torr. Mex. Bound. 108, t. 35.— 

 Gravelly or sandy soil, California to New ^lexico. 



N. longiflorus, Gray. Radical leaves more canescent : calyx 5-parted, free from and 

 much shorter than the narrow oblong capsule, its lobes equal : corolla narrower, firmly 

 gamopetalous, fully 3 lines long, 3 or 4 times longer than tlie caly.x : filaments long-mona- 

 delphous : seeds short-oval. — Proc. Am. Acad. xii. 60. — S. California, Wallace, Lemmon. 



2. LOBifiLIA, L. (Commemorates JI/a^^Aias (fe /' (9ie/, latinized Zo5eZi«<s, an

 common in the Atlantic, almost absent from the Pacific United States. Tube 

 of the corolla more or less disposed to split up in age into three pieces or into 

 its five petals ; at least the two shorter anthers with a bearded tuft at tij). 



§ 1. HoMOCHiLus, A. DC. Lips of the corolla somewhat equal ; one of them 

 3-toothed, the other 2-parted : flowers long-jjeduncled from the axil of leaves 

 or large leafy bracts, in ours red and yellow : perennials. 



L. laxiflora, HBK., var. angUStif olia. Tall and branching : leaves lanceolate or 

 even linear, 3 or 4 inches long, denticulate : peduncles 2 to 4 inches and corolla an inch 

 long: cal3'x-lobes hardly longer tlian the tube. — L. persiaefulia, HBK., not Lam. L. 

 CuL-anillesii, Mavt.; Hook. Bot. Mag. t. 3600. — Damp ground, just below the Mexican 

 border of Arizona, north of Arispe, Thurher. (Mex.) A form intermediate in the breadth 

 of the leaves between the var. and the L. Cavanillesii, Cav. Ic. t. 518, or the plant culti- 

 vated as Siphocampijlus hicolor. Anthers sometimes long-hirsute externally, sometimes 

 nearly naked. 



§ 2. EuLOBELiA. {Eulohelia, Hemipogon, & Holopogon, Benth. &, Hook.) 

 Larger lip of the corolla 3-parted or o-cleft and spreading or dependent; the 

 other two lobes either erect or turned backward : flowers racemose or spicate.

 aiithers naked at tip: perennial from slender offshoots, the 'llowering plants dying througliout in 

 autmnn. 



L. cardinalis, L. (Cakdinal-flowee.) Minutely pubescent or glabrous : stem 2 to 4 feet 

 high, commonly simple: leaves from oblong-ovate to oblong-lanceolate, tapering to both 

 ends, irregularly serrate or serrulate : lower bracts leafy : tube of calyx and capsule hemi- 

 splierical, much shorter than tlie subulate linear lobes : tube of the corolla about an incli 

 long: seeds oblong, rugose-tuberculate : the intense red of the corolla varying rarely to 

 rose-color or even wliite.- Bot. Mag. t. 320; Bart. Med. Bot. t. 48. — Wet' ground, New 

 Brunswick to the Saskatchewan, Florida, and the borders of Texas. 



L. splendens, "Willd. More slender, glabrous or nearly so : leaves lanceolate or almost 

 linear, glandular-denticulate, all but the lower sessile: seeds less tnbercnlate : otherwise 

 very like the preceding. — Hort. Berol. t. 86, the corolla-lobes larger and longer than in 

 wild specimens. L. Texensh, Raf. Ann. Nat. (1833) 20. — Wet grounds, Texas and through 

 New Mexico and Arizona to southern borders of San Diego Co., California, Pnlwpr. 

 Also Mexico. Lobes of the corolla in our plant (as in many Mexican) only 3 to 6 lines

* * Flowers blue or partly white, sometimes varying to white : tips of the three larger anthers 

 naked or sliort-beardcd, or rarely with a tuft like the other two. ^ 



H— Flowers rather large (tube of the corolla half or over a third of an inch long), spicate-racemose : 

 capsule short and broad : stems leafy: plants perennial, mostly h_v offsets.
