Gerardia. SCROPHULARIACEJ3. 293 



if at all mucronulate at base : capsule elliptical in outline, 4 lines long : otherwise nearly 

 like a scabrous form of the next, into which it may pass. Benth. in DC. 1. c. ; Gray, Man. 

 1. c. G. longifolia, Benth. in Comp. Bot. Mag. i. 208, not Nutt. Plains and prairies, from 

 Saskatchewan and Dakota to W. Arkansas, and east to Wisconsin and Illinois. 

 G. purpurea, L. Commonly a foot or two high, with virgate rather spreading branches : 

 leaves usually spreading, narrowly linear, either somewhat scabrous or smooth with 

 merely scabrous margins : pedicels shorter than calyx, mainly opposite : teeth of the 

 calyx acute, from very short and distant to half the length of the broad tube (then with 

 broad base and narrower sinuses): corolla an inch or less long: anther-cells cuspidate- 

 mucronate at base : capsule globular, 2 or 3 lines long. Spec. ii. 610, in part (confounded 

 with G. tenuifolia), & of syn. Pluk., &c. ; Bart. Fl. Am. Sept. iii. t. 97. G. marit.ima, var. 

 major, Chapm. Fl. 000. Low and moist grounds, Canada to Florida and Texas near the 

 coast, also Great Lakes to Illinois, &c. (Cuba.) A polymorphous species, of which the 

 following are extreme forms. 



Var. fasciculata, Cfhapm. Usually taller, 2 to 5 feet high : leaves (and mostly 

 branches) often alternate (and the cauline fascicled in the axils), rery scabrous, narrowly 

 linear or nearly filiform : pedicels in great part alternate : corolla commonly a full inch 

 long. Fl. 300. G.fasciculuta, Ell. Sk. ii. 115. 8. Carolina to Florida, Texas, and Ar- 

 kansas, usually in brackish soil. 



Var. paupercula. A span to a foot high, smoother : stem more simple or with stricter 

 branches : pedicels mainly opposite : flowers decidedly smaller : corolla usually only half 

 inch long, lighter rose-purple : calyx-teeth deltoid-subulate from a broad base, leaving com- 

 paratively narrower sinuses, sometimes over half the length of the tube. G. purpuren, 

 Sims, Bot. Mag. t. 2048 ; Hook. Fl. ii. 204. G. intermedia, Porter, in herb., a name to be 

 adopted if a distinct species. Lower Canada to Saskatchewan, and southward from 

 coast of New England to Penn., N. Illinois and Wisconsin. A maritime form has many 

 spreading branches. 



G. maritima, Raf . A span or two high, with short branches from below, smooth : 

 leaves fleshy, obtuse; the floral small: flowers accordingly in a more naked simple 

 raceme: pedicels about the length of the calyx : teeth of the latter broad, short, and very 

 obtuse: corolla glabrous, half inch, or in a Texan form (var. ymnd/jlora, Benth., G. spici- 

 flora, Engelm. PI. Lindh. i. 19), three-fourths inch long: anther-cells mucronulate at base: 

 capsule globular or ovoid, 2 or 3 lines long. N. Y. Med. Rep. ii. 361 ; Nutt. Gen. ii. 46; 

 Benth. 1. c. G. pnrpnrea, var. crass/folia, Pursh, Fl. ii. 422. Salt marshes on the coast, 

 Maine to Florida and Texas. 



+~ * Pedicels from once to thrice the length of the calyx, always much shorter than the corolla: 

 inflorescence or ramification paniculate; some (lowers appearing terminal: anthers mucronulate 

 at base. 



G. Plukenetii, Ell. Commonly 2 feet high, with many slender spreading branches : 

 leaves all filiform, smooth or barely scabrous, seldom in fascicles, only some of the upper 

 alternate : pedicels 2 to 4 lines long and alternate in upper axils, and solitary terminating 

 leafy filiform branchlets : calyx truncate and with very short subulate teeth : corolla 

 three-fourths to near an inch long, loosely long-villous in throat, as are the filaments 

 and anthers. Sk. ii. 114. Antirrhinum purpurcum, &c., Pluk. Aim. 34, t. 12, fig. 4, poor. 

 G. linifolia, Benth. Comp. Bot. Mag. i. 209, not Nutt. G. filifolia, var. Guti'sii, Benth. in 

 DC. 1. c. G. setacea, Chapm. Fl. 300, not Walt. ? nor Ell.? nor Pursh, nor Nutt., &c. 

 Sandy or wet pine barrens, Middle Georgia, Alabama, and Florida. Larger leaves an inch 

 long. 



Var. microphylla. Slender: cauline leaves setaceous, half inch or less long, 

 rather few, and on the branchlets reduced to minute subulate bracts (mostly less than a 

 line long): corolla half to two-thirds inch long. G. ap/u/l/a, var. grandiflom, Benth. 

 Comp. Bot. Mag. 1. c. Louisiana, Drummond, Hale. Keys of Florida, Blodyett, &c. 

 Plukenet's figure (Aim. t. 12, fig. 4) may be rightly referred here ; but it is not character- 

 istic. 



H -t -f- Filiform pedicels about equalling or commonly exceeding the corolla in length : woolly 

 anthers cuspidate or almost aristate at base. 



H- Leaves all but the lowest cauline alternate and copiously fascicled in the axils. 

 G. filifolia, Nutt. Smooth, often 2 feet high, paniculately branched above, very leafy up 

 to the loose paniculate-racemose inflorescence : leaves numerous in the fascicles, filiform
