There are many species of forage value in the genusAlysicarpus. The optimum period for the flowers to bloom is between 9 and 11a.m., the optimum temperature and humidity required being 76·2 to 80·5° F. and 74 to 57 per cent., respectively. Flowering starts in the middle of August and continues for about two months. InA. longifolius, A. buplurifolius andA. vaginalis, flowering takes place in two flushes; the second flush being of considerably smaller duration than the first. Dehiscence of anthers commences when anthesis begin, and is completed when the flower is ready for tripping,i.e., between 9 and 10a.m. The stigma is receptive in all species studied, between 10 and 11a.m. The time required from blooming to closing of the several parts, is about two hours. In the speciesA. rugosus var.styracifolius, A. buplurifolius, andA. vaginalis, the surface of the stigma is in level with the surface of the anthers; whereas, inA. rugosus var.heyneanus—Types A, B and C,A. pubescens andA. longifolius, the style protrudes 1 mm. beyond the anther lobes. Self-pollination generally occurs in the species where the stigmatic surface is in level with the surface of the anthers, but the same is usually prevented in the species where the style protrudes well beyond the anther lobes.
