Progress in Malesian botany

Dr. R. Grolle, Jena, started a revision of the hitherto published records and determination of unstudied collections of Hepaticae from New Guinea (and neighbouring regions). The results will be successively published in the Journal of the Hattori Botanical Laboratory under the title ”Lebermoose aus Neuguinea”. Nos 1-5 are concluded and in print. Next subjects will be Zoopsis, Acromastigum and Lophocoleaceae. At the Rijksherbarium, Mr. A. Touw has finished the primary generic identification of Malesian mosses so that these materials, of which he is in charge, are now available to workers.
