Polygonatum biflorum (WaltJ El 



beech, sweet gum, and pin oak. Grimes reported it from Putnam County 

 where it was associated with hemlock. 



Plants of this species with 3 leaves have been named Maianthemum 

 canadense f. trifolium (Farw.) Vict. (Contr. Lab. Bot. Univ. Montreal 14: 

 17. 1929.)

la. Maianthemum canadense var. interius Fern. (Rhodora 16: 211. 

 1914.) Map 655. The variety has about the same range as the species in 

 the northern part of Indiana but it is not found in the southern part of 

 the state. The species and its variety are of nearly equal abundance but 

 one rarely finds the two in the same colony. The mass distribution of the 

 variety is about the Great Lakes but it has outlying posts as far east as 

 Massachusetts and ranges westward through central Ohio to central Iowa 

 and northward.

Leaves more or less puberulent beneath, at least on the veins, 6-16 in number, 2-6 cm 



wide and 4-13 cm long, narrow- to wide-elliptic, or slightly ovate-elliptic, generally 



broad at the base, rarely somewhat cuneate; peduncles usually beginning at the 



second leaf axil, rarely beginning at the first or at the third leaf axil, 1-4-flowered, 



usually 1- or 2-flowered, or a mixture of 1 and 2 flowers; flowers 7-12 mm long; 



filaments of stamens more or less papillose; stems usually beginning to curve above 



the second leaf; rhizomes near the surface; plants usually found in thick woodland. 



1. P. pubescens. 



Leaves glabrous beneath, mostly 10-21 in number; blades of wideleaf forms 2.5-10.5 

 cm wide and 12-21 cm long, very broadly ovate-elliptic or broadly elliptic, those 

 of the narrowleaf forms 1.5-3 cm wide and 6.5-14 cm long, mostly narrow-elliptic 

 or oblong-elliptic; peduncles very variable in length, rarely more than one from an 

 axil, the first one generally from the third to the fifth leaf axil of the wideleaf
