SILICA-SCALED CHRYSOPHYTES OF WUHAN,A PRELIMINARY NOTE

Samples from three ponds in Wuhan Botanical Garden and from a pond near Wuhan Eastern Lake, obtained in November 1986, contained a rather rich flora of silica-scaled chrysophytes, altogether 11 species of the genera Spiniferomonas, Paraphysomonas, Chrysosphaerella, Mallomonas and Synura. They have been listed in Table 1, and electron micrographs of their silica scales, spines and bristles have been given in Plate Ⅰ. These algae have hardly been investigated previously in China, and all the species found at Wuhan are new to the country. Most of them are otherwise common in parts of the world, some of them must certainly be considered cosmopolitan.
