fruit; calyx appressed-puberulent. with short white hairs at the sinuses, frequently- 

 tinged with red, much-inflated when mature, 6-18 mm. long, 3-11 mm. wide, 

 teeth acute, the upper about 3 times as long as the others, the latter folding over 

 and appearing as though truncate with a long index-finger pointing outward; 

 corolla varying greatly in size, from 7 to 23 mm. long; lower corolla lip densely 

 bearded, spreading and much longer than the upper lip, usually with a reddish- 

 brown blotch below the middle lobe and numerous smaller dots down the throat; 

 style puberulent, the stigma lips unequal; capsule short-stipitate, oblong; seeds 

 reticulate. 



In moist or wet places generally, in wet meadows, on edge of streams, wet 

 rocks and springy places, in N. M. (Dona Ana Co.) and Ariz. (Graham, Gila, 

 Pinal, Cochise and Pima cos.), Mar.-Sept.; Ida. to B.C., s. to Chih., N.M., Ariz, 

 and Baja Calif. 



9. Lindernia All. False Pimpernel 



Diffuse annual herbs; leaves opposite, denticulate to nearly entire; bracteoles 

 none; flowers in axils of most leaves; sepals 5, distinct; corolla blue-violet, bilabi- 

 ate, the upper lip with 2 short erect acutish lobes, the lower lip much larger and 

 spreading, with 2 hairy yellow ridges within the throat; filaments 4, didynamous, 

 the upper short and antheriferous, the lower forming the hairy ventral ridges of 

 the corolla and projecting from apex as sterile knobs; stigmas distinct, lamelliform; 

 capsule septicidal, ovoid to ellipsoid, the septum persisting as a thin plate; seeds 

 smooth or finely lined transversely. 



About 80 species, mainly in warm regions of Asia and Africa. 



1. Lower pedicels shorter than their subtending leaves; main leaves obovate to 

 elliptic or ovate, rounded or narrowed to base; capsule often 

 equaled or exceeded by the calyx lobes 1. L. duhia. 



1. Lower and upper pedicels exceeding their subtending leaves; main leaves ovate 

 to elliptic, broadest at the rounded to cordate base; capsule mostly 

 exceeding the calyx lobes 2. L. anagallidea. 



1. Lindernia dubia (L.) Penn. Fig. 688. 



Plant glabrous, the simple or much-branched stems erect-ascending, to 35 cm. 

 high; leaves narrowly elliptic to oblong or obovate, to 3 cm. long, the lower ones 

 narrowed but the upper ones rounded and clasping at base, entire to remotely 

 dentate; pedicels 5-12 mm. long, stoutish; calyx lobes linear; corolla 7—10 mm. 

 long, those of the later flowers mostly falling unopened; style 2.5-3.5 mm. long; 

 capsule obliquely ellipsoid, about 4 mm. long. Incl. subsp. major Penn., Ilysanthes 

 gratioloides (L.) DC, /. dubia (L.) Barnh. 



In mud of swamps and stream margins, in mud at edge of ponds and lakes, 

 and in pools along water courses, in Okla., (Alfalfa, Adair and Pushmataha cos.) 

 and in e. Tex. and (?) Ariz., June-Aug.; from throughout most of U.S., s. to S.A. 



2. Lindernia anagallidea (Michx.) Penn. Fig. 698. 



Plant glabrous, the slender stems diffusely branched, to about 2 dm. high; 

 leaves ovate to ovate-elliptic, to 2 cm. long, broadest at the rounded or clasping 

 base, the lowermost leaves often slightly narrowed at base, essentially entire; 

 pedicels filiform, to about 25 mm. long; calyx lobes linear; corolla 7-9 mm. long, 

 apparently all opening; capsules 4-5 mm. long. 



Sandy margins of streams and ponds, and in marshes, throughout most of Okla. 

 and Tex. except the Trans-Pecos, Apr.-Oct.; from throughout most of the U.S., 

 s. to S.A.
