2. Lobelia Nuttallii, Rcem, 8^ Schult. NuttalVs Lobelia. 



Stem veiy" slender, minutely scabrous, simple, or with few filiform erect branches ; leaves 

 remotely denticulate , the cauline oblong-linear , radical oblong-spatulate ; raceme virgjite, 

 loose, few-flowered ; pedicels shorter than the flower, with minute bracteoles near the base ; 

 capsule rather obtuse below. — Rcem. <^ Schult. syst. 5. p. 39 ; Torr. fl. I. p. 240 ; Beck,

Biennial. Stem 1 - 2 feet lugh, erect, often flexuous. Leaves about an inch long and 

 1-2 lines wide ; the radical ones a little hairy. Flowers remote, in a slender raceme, pale 

 blue, smaller than in the preceding species ; the pedicels 2-3 lines long, with two opposite 

 minute bracteoles, often colored. Seeds ovate, rough. 



Sandy swamps and borders of salt marshes, Suffolk county, Long Island ; also near Ja- 

 maica {Mr. F. C. Schcsffer). July - September. This species, which is very common in 

 the sandy region of New-Jersey, is nearly allied to the preceding, and has been confounded 

 with it by many botanists. It is best distinguished by its more slender habit, and shorter 

 pedicels with small bracteoles near their base. 



3. Lobelia spicata, Lam. Pale-spiked Lobelia. 



Stem simple, pubescent ; leaves pubescent, sessile, mostly obtuse, obscurely denticulate , 

 the cauline oblong, radical spatulate-obovate ; raceme virgate, naked ; bracts about the length 

 of the pedicels ; calyx smooth, the segments subulate, nearly as long as the tube of the corolla.

Root perennial. Stem 1-3 feet high, erect, mostly straight, rather slender. Radical 

 leaves 2 inches or more in length, nearly entire ; stem-leaves obscurely crcnate-denticulate. 

 Raceme spike-like, from six inches to a foot in length, many-flowered. Pedicels about 3 lines 

 long, erect, with a lanceolate-denticulate bract at the base. Flowers pale blue, about half an 

 inch long. Segments of the calyx not appendiculate at the base. Seeds acute at each end. 



Dry open woods, fields and meadows ; frequent. July -August. The synonym of Elliott 

 belongs perhaps to L. leplostachys, DC, as that species commonly takes the place of L. 

 spicata in the Southern States.
