Gerardia. SCROPHULARIACE^. 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. 

 I. c. G. longifoUa, 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. tenitifolia), & of syn. Pluk., &c. ; Bart. Fl. Am. Sept. iii. t. 97- G. maritima, var. 

 major, Chapm. Fl. 300. — 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, Chapm. Usually taller, 2 to 5 feet high : leaves (and mostly 

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

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

 long. — Fl. 300. G. fasciculata, Ell. Sk. ii. 115. — S. 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. purpurea, 

 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. grandiflora, Benth., G. spici- 

 Jlora, 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. purpurea, var. crassi/olia, 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 flowers 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 purpureum, &c., Pluk. Aim. 34, t. 12, fig. 4, poor. 

 G. linifolia, Benth. Comp. Bot. Mag. i. 209, not Nutt. G. JilifoHa, var. Gatesii, Benth. in 

 DC. 1. c. G. setacea, Chapm. Fl. 300, not Walt. ? nor E11.7 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. aphyUa, var. grandiflora, Benth. 

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

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

 istic. 



■t— -t— .t~ Filiform pedicels about equalling or commonh' 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. filif olia, Nutt. Smooth, often 2 feet high, paniculately branched above, very leafy up 

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