 Amphicarpa bracteata 

 var. comosa (L.) Fern. 



from the dune area of Lake Michigan. My Posey County specimen is not 

 typical and may be a southern representative of the species.

3857. CLITORIA L. 



1. Clitoria mariana L. Butterfly-pea. Map 1276. This species is very 

 rare on the crests of a small number of wooded, sandstone ridges in a 

 few of our southern counties.

3860. AMPHICARPA Ell. Hog Peanut 

 [Fernald. Recent Discoveries in the Newfoundland Flora. Rhodora 35: 

 276. 1933.] 



Pubescence of sutures of pods from petaliferous flowers upwardly appressed (at least 

 on the basal half) ; pubescence of stem colorless and appressed, sometimes some- 

 what spreading in parts and slightly tawny; median stipules generally about 3 mm 

 long; floral bracts mostly 2-2.5 mm long; calyx tube, measured to the lowest sinus, 

 mostly about 4 mm long; mature seed about 3.5 mm long 1. A. bracteata. 



Pubescence of pods from petaliferous flowers downwardly appressed (at least on the 

 basal half); pubescence of stem tawny and widely spreading; median stipules gen- 

 erally about 4 mm long; floral bracts usually about 3 mm long, sometimes as short 

 as 2.5 mm; calyx tube, measured to the lowest sinus, generally 4.5-5 mm long; 

 mature seed 3.8-5.5 mm long 2. A. bracteata var. comosa. 



1. Amphicarpa bracteata (L.) Fern. (Amphicarpa moiwica (L.) Ell. 

 and Falcata comosa (L.) Ktze. of American authors.) Map 1277. Usually 

 frequent in moist woods throughout the state. Our two species seem to 

 intergrade and some authors regard the next one as only a race or vigorous 

 form of this species. Schively expresses this doubt when she says the 

 var. comosa is "an extremely vigorous" form of this species (Contr. Bot. 

 Lab. Univ. Pa. 1: 356. 1897). Besides the winter pods, this species has 

 subterranean 1-seeded pods, autumnal 1 -seeded pods, and pods, which are 

 usually 3-seeded, from petaliferous flowers.
