71. MILKWEED FAMILY. Order ASCLEPIADACE. . 
Plants with milky juice, tough bark, and in other respects like the Dogbane family, but 
with the 5 short stamens all united by their filaments into a ring or tube, the anthers grown 
fast to the large stigma, and the grains of pollen in each cell cohering into a waxy or tough 
mass. Flowers in simple umbels. Pods a pair of many-seeded follicles: seeds furnished 
with a long tuft of silky down at one end (Fig. 229). The flowers in this family are 
curious, but are too difficult for the beginier. The two common genera may be distin- 
guished as follows : — 
Corolla 5-parted, reflexed: five hoods to the stamens, with a horn in each, (Asclépias) MILKWEED. 
Corolla, &c. as in Milkweed, but the hoods without any horn, (Acer‘étes) GREEN-MILKWEED.
