Abstract
IN their researches on Bonnemaisonia asparagoides (Woodw.) C. Ag., J. Feldmann and G. Feldmann1 describe the germination of the carpospores. After showing amœboid movement, the spores become round and surrounded by a wall. The first division is equatorial and at right angles to the substratum. Other walls parallel to the first are formed, and subsequent divisions lead to the formation of a hemispherical cushion of cells from the edge of which radiating filaments ultimately develop. This account agrees with the earlier published descriptions given by Kylin2,3 and Chemin4, and also Golenkin5, who recorded some variation in the position of the first wall.
