1. Peduncles longer than the subtending leaf-bracts; calyx-segments shorter 

 then the capsule /. dubia. 



1. Peduncles shorter than the subtending leaf-bracts; calyx-segments as long as 

 the capsule or longer /. attenuata. 



1. Ilysanthes dubia (L.) Barnh. Long-stalked False 



Pimpernel. 



Stem square, at first simple and ustially erect, later much branched 

 and diffusely spreading, 3-1 (J in. long. Leaves ovate, obovate, or oblong, 

 usually sessile, clasping, entire or sparingly toothed, 3^-1 in. long. 

 Coiolla pale lilac, 34^3^ i^- long, the peduncles usually considerably 

 longer than the subtending leaf -bracts; calyx-segments usually shorter 

 than the capsule. In wet places. July-September. Meigs, Fairfield, 

 Licking, Franklin, Huron, Auglaize, Defiance and Scioto Counties. 



2. Ilysanthes attenuata (Muhl.) Small. Short-stalked False 



Pimpernel. 

 Stem square, erect or ascending, 3-16 in. long, the branches spread- 

 ing. Leaves ovate, obovate, or oblong, 3^-1% in. long, sparingly 

 toothed. Corolla pale lilac to nearly white, ]i-}/2 in. long; peduncles 

 mostly shorter than the subtending leaf -bracts; calyx-segments as long 

 as the capsule or longer. In wet places. May-October. Cuyahoga, 

 Stark, Summit, Madison, Scioto, and Highland Counties. 



The two species are evidently closely related as inter- 

 mediates show peduncles longer than the subtending leaf- 

 bracts, but with calyx-segments as long as the capsule.

 Tall, erect herbs, with alternate, entire or dentate leaves, 

 and showy, yellow, purple, or white flowers in long, terminal, 

 usually one-sided racemes. Calyx 5-parted. Corolla declined, 

 slightly two-lipped, the tube contracted above the ovulary, 

 then abruptly inflated. Stamens four, didynamous, included. 

 Seeds numerous, rugose. 



1. Corolla purple to white, 13^-2 in. long; stem pubescent; leaves slender- 



petioled D. purpurea. 



1. Corolla yellow, about % in. long; stem smooth; leaves sessile D. lutea. 



1. Digitalis purpurea L. Purple Foxglove. 



Stout, erect, pubescent herb, usually biennial, 2-5 ft. high. Lower 

 leaves ovate or ovate-lanceolate, 6-10 in. long, acute at the apex, nar- 

 rowed at the base into petioles, dentate; upper leaves smaller, sessile. 

 Racemes 1 ft. or more in length, dense, one-sided; flowers purple to 

 white, 13^-2 in. long, drooping, the corolla spotted within; upper calyx- 

 lobe narrower than the others. Escaped from cultivation. June- 

 August. Cuyahoga and Lake Counties. From Europe.
