4 LOBELIACEiE. Lobelia. 



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

 refic'XL'd, sometimes even pinnatifid-iootlied, tlie teeth callous : spike-like raceme few - 

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

 bracts: calyx-lol>es 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. crussittscula, Hook. Comp. 

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

 Tube of the corolla nearly half an inch long. 



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

 iiunieiDiis ; the upper passing into foliaceous bracts: lip and upper part of the tube of the corolla 

 glabrous witliin. 



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

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

 irregularly serrate or repand-denticulate (the larger 5 or 6 inclies 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 antliers wholly naked at tip. — Dill. Elth. t 242 ; Jacq. Ic. Rar. t. 597 ; Bot. Reg. t. 537. 

 L. (/laiidu/usa, Lindl. Bot. Reg. xxxii. t. 03. — Wet grounds, Canada to Georgia, Louisiana, 

 and west to Kansas and Dakotah. Runs into some varieties; var. Lndoviciana, A. DC, is a 

 south-western smoother form, with thickish leaves : there are also gai-den hybrids. Auricles 

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

 liglit 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 tlie 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. ammui, Ell. 1 

 A. DC. Prodr. vii. 377, not Michx. L. (jlandn/osa, 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. 3202, not of Ell.): a greener form, with slender, 

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

 more sccund. — L. glandalosa, var. obtusifulia, A. DC. 1. c. ; Bertol. Misc. x. 29. — N. Carolina 

 to Florida and Texas. 



L. amcena, Michx. Green and glabrous throughout, or nearly so: 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 narrow 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. s>/philltica,Wii\t. Car. 218; Juss. Ann. Mus. xviii. 

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

 L. colorata, Don, Brit. Fl. Gard. n. ser. t. 180, and L. hortensis, 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 absolutel}' naked, or sometimes obscurely bordered. — To this belongs 

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



Var. obtusata. 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. amana, Chapm. Fl., in 

 part. — Middle Florida, Chapman. 



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

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