114 BIBLIOGRAPHY descriptions of 24 novelties, one of which is regarded by M. Peyritsch as the type of a new Passifloreous genus (Basananthe, Peyr.), related to Paschanthus, Burch., and Acharia, Thg.

The fol- lowing species were carefully observed for some days prior to the eclipse, and the hours noted at which their c< sleep" commenced, and reached its maximum: — Mimosa pudica and scnsitiva, Gram- manthes gentianoides, Arnicia zygomeris, Cccsalpinia s^p'aria, Acacia juliorissin, and Porliera hygrometrica. The author de- tails the result of observations during the eclipse on Arnicia and Grammanthes, which he selected as showing the greatest susceptibi- lity to light. The leaves of the Arnicia under glass with the com- mencement of the eclipse began to droop, and at the maximum of darkness were half reilexed: at the end of the eclipse, ihey were again normally expanded. The flowers of Grammanthes also, under glass, which were expanded at the beginning of the eclipse, were all closed about the middle. At the end, most of the flowers at- tempted to open, though with but partial success. The author's numerous thennometrical observations lead him to refer the sleep- phenomena of sensitive plants to the direct thermal influence of the solar rays.
