. A manual of poisonous plants, chiefly of eastern North America, with brief notes on economic and medicinal plants, and numerous illustrations. Poisonous plants. 160 MANUAL OF POISONOUS PLANTS a shorter or longer period the protoplasm contracts forming little heaps which contain the spores; the parts of the reproductive body are called the sporangium or spore case, the peridium or the wall of the case, the stipe or stalk, the columella or central axis in the spore case, the capillitium or fine threads, and the spores. The spores after absorbing water, germinate by breaking the wall and move about by means of ciha; sexual reproduction is entirely absent. The division Myxothallophyta includes three classes: Acrasieae without swarm cells; Plasmodiaphorales of which the club root of Cabbage, Plasmodio- phora Brassicae is an example (a very destructive parasite upon cabbage, turnip, etc., in Europe and the Eastern States) ; and Myxogasteres which con- tains a great many species and genera common on spent tan bark, rotten logs, and the ground. Of the third class Stemonitis, Physarum, Lycogola and Fuligo are common genera. No species of this class is poisonous so far as known. EUTHALLOPHYTA Cells generally with cell membrane, with one or more generations, sexual reproduction frequently absent, the fertilized spores when present, with 1 cell which later separates from the mother plant, or a several-celled body resulting from the fertilization of the female fructifying body, which later develops into a new plant. This division includes such plants as bacteria, blue green algae, the green algae, rusts, smuts, mildews, moulds, puffballs, mushrooms and toad- stools. SCHIZOPHYTA Small unicellular organisms, never green but frequently of other colors, blue greens, etc., reproduction asexual by fission, spores formed in the interior.
