by the way, is a very wonderful study in itself. 
PURPLE MILKWEED 
Asclépias purpurdscens. Milkweed Family. 
A handsome species with large, deep crimson or pur- 
ple flowers found in dry fields, roadsides and thickets 
from New Hampshire to Ontario, Minnesota, Virginia, 
and Kansas during June, July, and August. The 
usually single stalk rises from two to four feet high, 
and it is tough-fibred, finely grooved and very leafy. 
It is so full of milky juice that it fairly spurts out when 
a stem or leaf is broken. The long, oval leaf tapers to 
a point toward the tip, and narrows at the base into 
a short stem. It is smooth above, and finely downy 
beneath. The entire margins are sometimes slightly 
wavy. The veins are wide-spreading, and the midrib 
is strong. They are arranged in alternate pairs. 
The divisions of the corolla are oblong in shape 
and deep purple in colour. The short, broad hom 
tapers to a sharp tip, which turns acutely toward the 
centre. The numerous flowers are loosely clustered 
in rounding terminal heads. 
SWAMP MILKWEED 
Asclépias incarnata. Milkweed Family. 
This species is found commonly in and about swamps 
from July to September and ranges through New 
Brunswick to Tennessee, Kansas, and Louisiana. The
