(ancient Greek and Latinized name). Asclepiaddcew. Miurwsan. SILKWEED. Many herbs, mostly North American, generally with opposite or whorled lvs., milky juice, and umbels of odd fls. The fls. are gamopetalous, the corolla segments generally strongly reflexed; stamens 5, attached to the corolla, the authors more or less united about the stigma; be tween the corolla and the stamens is a crown of five cornucopia-like appendages ; pollen coheringinto awaxy mass (pollinium), which is removed bodily by insects which visit the H. The pollination of an Asclepias ii. is shown in Fig. 149. The pollen-masses are usually twin (as at b), and the handle or caudicle lies in a. chink on the side of the stigma. The pollen-masses become at 'tached to the legs or mouth parts of the insect, and are thereby transferred to another ii. The Milkweeds are common in waste places in N. Amer., and are rarely cult. Several species (described below) have been int. by dealers in native plants. The Butterfly-weed and some others are very showy and worthyof more general attention. The large-lvd. kinds are desirable when heavy foliage eflects are wanted. They are all perennials of the easiest culture. Prop. by division, rarely by seeds. See Gray, Syn. Fl. N. Amer. 2., pt. 1 (which is here followed).
