4. Calyx lobes typically much-abbreviated, much shorter than the tube, the 



sinuses broad and open; leaf blades linear to filiform or subulate, 

 always entire (5) 



5(4). Primary leaves to 4 cm. long, spreading or widely arcuate-ascending; stem 

 smooth to more or less scabridulous, commonly angled; stigma 

 2-3 mm. long 4. A. purpurea.

1. Agalinis maritima (Raf.) Raf. Seaside gerardia, salt marsh gerardia. Fig. 



702. 



Plant to about 6 dm. high, usually much smaller, with short leafy branches 

 below, smooth; leaves fleshy, broadly linear, obtuse, to about 3 cm. long and 

 3 mm. wide; flowers few, in a more or less naked simple raceme; pedicels 2-10 

 mm. long, shorter to longer than the floral bracts; calyx tube broadly campanulate, 

 2-3 mm. long in anthesis, slightly longer in fruit; calyx lobes broad, short and 

 thick, 0.5-1 mm. long, very obtuse to acutish; corolla rose-pink, glabrous, 1.2-2 

 cm. long; anther cells mucronulate at base, 1.3-2.3 mm. long, villous to glabrous; 

 capsule globular to ovoid, 4-6 mm. long. A. spiciflora (Engelm.) Penn., Gerardia 

 maritima Raf. 



In salt marshes and beach dunes along the Tex. coast, May-July; from N.S. 

 to Fla. and Tex., also Mex. and W. I. 



Our material is usually referred to var. grandifiora (Benth.) Shinners, charac- 

 terized by having anther cells 1.8-2.3 mm. long and usually villous with long 

 white hairs; pedicels mostly equaling or longer than the bracts; calyx lobes 

 typically obtuse; corolla 1 .5-2 cm. long. 



2. Agalinis tenuifolia (Vahl) Raf. 



Plant usually smooth, to about 5 dm. high, usually much smaller, paniculately 

 much-branched; leaves mostly narrowly linear and plane, spreading, to 6 mm. 

 wide, about equaling the lower but mostly shorter than the uppermost pedicels; 

 inflorescence racemose; pedicels filiform, widely divergent, commonly 1-2 cm. 

 long at anthesis; calyx tube 2-4 mm. long; calyx lobes broadly triangular to 

 subulate, usually less than 1 mm. long, rarely to 2 mm.; corolla pink to mallow- 

 purple or paler, 1-2.3 cm. long, glabrous except for the ciliate margins of the 

 nearly equal lobes, its upper lip arching over the stamens; anther cells cuspidate- 

 mucronate at base, densely to sparingly villous; capsules 3-7 mm. long. Gerardia 

 tenuifolia Vahl. and var. leucanthera (Raf.) Shinners. 



In moist areas along streams, about ponds, in wet meadows, fields and low 

 flatwoods, in Okla. (Pittsburg Co.) and n.e. Tex., Sept. -Nov.; from Me. to Man. 

 and N.D., s. to Fla. and Tex. 



Our material is usually referred to subsp. leucanthera (Raf.) Penn. character- 

 ized by having a corolla 15-23 mm. long and calyx lobes less than 1 mm. long. 



3. Agalinis heterophylla (Nutt.) Small. Prairie Agalinis. 



Plant to about 6 dm. high, the stem smoothish, paniculately branched or the 

 branches virgate; leaves rather erect, thickish or rigid, the lowest or primary 

 ones broadly linear (to 45 mm. long and 8 mm. wide) and 3-cleft or laciniate, the 

 others narrowly linear and mucronate-acute, those of the branchlets short and
