Caoutchouc in Hippoeratea (Bcih. Bot. Cent, bd.xi. ht. 5, pp. 2-83, 

 358 ; plate). — Herr Felix Eugen Fritsch has examined twenty-three species 

 of Hippoeratea, forty-one species of Salacia, and one species oi Campy - 

 lostemon. He finds that indiarubber occurs in twelve species of Salacia, five 

 species of Hippoeratea, and in Campy lostemon. The laticiferous system is 

 like that of the Apocynaccce and Asclcpiadaccce. The tubes are narrow 

 and not much branched. These tubes occur in the ovule, under the nerve 

 which traverses the raphe. The character of the latex is not the same 

 in the different species. This, however, is but a small part of the paper, 

 which contains a very detailed and thorough description of the histology 

 of the genera mentioned. — G. F. S.-E.
