The cells of the anthers are at first commonly four, all parallel, becoming two only at maturity. In some plants the four are retained, as in the anthers of Ephedra. (353.) In others, as mallows, all the cells coalesce into one. (352.) 501. Appendages of many kinds distinguish tho stamens of different species. In the Ericaceas there are horns, spur?, tails, queues, etc. In onions and garlic the filament is 2 or 3-forked. bearing the anther ou one of the tips. Sometimes a pair of appendages appear at base, as if stipulate. It is often conspicuously clothed with hairs, as in Tradescantia. 859.
