4 LOBELIACE^. Lobelia. 



obovate or spatulate; the upper oblong-linear, often crowded and widely spreading or 

 reflexed, sometimes even pinnatifid-tootlied, tlie teeth callous : spike-like raceme few - 

 many-flowered : short pedicels mainly appressed and equalled by the short foliaceous 

 bracts : calyx-lobes lanceolate or ovate-lanceolate, strongly and pectinately toothed, 

 auriculate-appendaged at base, fully half the length of the puberulent tube of the corolla : 

 anthers all iiairy above, but only the two shorter with conspicuous beard at tip : capsule 

 very short. — A. DC. Prodr. vii. 377; Bertol. Misc. x. 28. L. crassiuscula, Hook. Comp. 

 Bot. Mag. i. 100. — Open pine barrens, Louisiana, Alabama, and Florida; flowering late. 

 Tube of the corolla nearly half an incli long. 

 ++ ++ Leave.s rather large and broad (1 to 5 inches long), from ovate to broadly lanceolate, 



numerous ; the upper passing into fuliaceous bracts: lip and upper part of the tube of the corolla 



glabrous within. 

 L. syphilitica, L. Somewhat pubescent with scattered hairs : stem rather stout, very 

 leafy, 2 or 3 feet high : leaves thinnish, lanceolate or oblong and tapering to both ends, 

 irregularly serrate or repand-denticulate (the larger 5 or 6 inches long) : spicate raceme 

 leafy below, a span to a foot long; calyx-lobes mostly hairy or ciliate, moderately shorter 

 than the tube of the corolla, the sinuses conspicuously appendaged by deflexed auricles : 

 larger anthers wholly naked at tip. — Dill. Elth. t 242 ; Jacq. Ic. Rar. t. 597 ; Bot. Reg. t. 537. 

 L, (jiandulosa, Lindl. Bot. lieg. xxxii. t. 63. — Wet grounds, Canada to Georgia, Louisiana, 

 and west to Kansas and Dakotali. Runs into some varieties : var. Luduviciana, A. DC, is a 

 south-western smoother form, with thickish leaves ; there are also garden hybrids. Auricles 

 of the calyx sometimes reaching the base of the ovary, sometimes short. Corolla bright 

 ligiit blue, rarely varying to white or purple ; its tube broader than in the following, 

 half an inch long. 



L. puberula, Michx. Soft-pubescent with very short and fine hairiness, 2 feet high : 

 leaves from ovate to oblong, mostly obtuse and an inch or two long, pale or slightly 

 hoary, callous-denticulate or more toothed; the upper passing into ovate foliaceous lower 

 bracts of the strict and virgate spike-like raceme : flowers mostly crowded, becoming 

 horizontal on the short appressed pedicels : calyx-lobes lanceolate, little shorter than the 

 tube of the corolla (about 4 lines long, rarely shorter in proportion); the auricles at the 

 sinuses short and rounded, commonly very short, often inconspicuous : larger anthers 

 minutely short-bearded at tip: ovary generally hirsute. — Fl. ii. 152. L. amixna, Ell. f 

 A. DC. Prodr. vii. 377, not Michx. L. glandulosa, Engelm. & Gray, PI. Lindh. i. 14.— 

 Damp sandy grounds, New Jersey to Illinois, Florida, and Texas. Passes insensibly into 



Var. glabella, Hook. (Bot. Mag. t. 3292, not of Ell.): a greener form, with slender, 

 more glabrous, and usually more naked virgate spike, glabrous calyx, &c., and flowers 

 more secund. — L. gtanduhsa, var. ohtuaifolia, A. DC. 1. c. ; Bertol. Misc. x. 29. — N. CaroUna 

 to Florida and Texas. 

 - Li. amdena, Michx. Green and glabrous throughout, or nearly §o : stem 1 to 4 feet 

 high, in the larger plants leafy to the virgate raceme : leaves thinnish, oblong-lanceolate 

 or narrower, mostly tapering to both ends, 2 to 4 inches long, irregularly serrate or den- 

 ticulate ; the upper passing into conspicuous lanceolate or linear bracts; these often glan- 

 dular-denticulate, and the foliaceous lower ones equalling the flowers : calyx lobes long 

 and very slender, little shorter than the n,arrow tube of the corolla, from filiform- to 

 linear-subulate, commonly quite entire, little widened and not auriculate at base: larger 

 anthers wholly naked or merely puberulent at tip : ovary glabrous : lobes of the large 

 lip of the corolla broadly ovate. — L. si/philiticci, Widt. Car. 218; Juss. Ann. Mus. xviii. 

 t.l, f.l. L. puberula, var. glabella, Ell. Sk. i. 267. L. glandulosa, var. glabra, A.DC. 1. c. 

 L. colnrnfa, Don, Brit. Fl. Gard. n. ser. t. 180, and L. horlensis, A.DC. 1. c, are a hybrid 

 form of this. — Deep swamps, N. Carolina to Florida. Raceme a span to a foot long; 

 tube of bright blue corolla half an inch long. Calyx-lobes sometimes with a few teeth ; 

 the sinuses absolutely naked, or sometimes obscurely bordered. — To this belongs 

 Clayton's plant referred by Gronovius to L. Cliffbrtiaiia, L. 



Var. obtus4ta. Cauline leaves oblong, obtuse, and almost entire : spicate raceme 

 virgate and naked : calyx-lobes subulate, shorter, only half the length of the tube of the 

 corolla : larger anthers densely very short-pubescent at tip. — L. amaina, Chapra. Fl., in 

 part. — Middle Florida, Chapman. 



Var. glandlllifera. A foot or two high, often slender and sparsely le.ived, below 

 sometimes hirsute-pubescent; leaves from oval to lanceolate-oblong, an inch or two long,
