In marshy or swampy places, New Brunswick to Saskatchewan, south 

 to Tennessee and Colorado. Flowering from July to September.

 the leaves smooth above and pubescent beneath, the flowers commonly 

 lighter red or pink.

Asclepias amplexicanlis J. E. Smith 



Plate 173 



Stems stout, erect or nearly so, smooth, pale green and glaucous, 

 rarely somewhat pubescent, 2 to 3 feet high. Leaves opposite, oblong- 

 ovate or oblong, blunt and minutely pointed at the apex, cordate-clasping 

 at the base, 3 to 5 inches long, i to 2 inches wide, the margins wavy-crisped. 

 Flowers numerous in a terminal, solitary, long-stalked umbel; pedicels of 

 the flowers downy, about i inch long. Flowers greenish purple; corolla

 Florida and Texas. Flowering in June and July. Young plants of this 

 and other species of milkweed are said to make excellent greens. 



The Intermediate Milkweed (Asclepias intermedia Vail)
