Dr E.D. Merrill is working on a MS index to William Jack’s papers. Mr R.D. Hoogland, Leiden, has finished his research on Dilleniaceae. The results will be embodied in a revision of the family in Flora Malesiana, a revision of Indo-Malaysian Tetracera, and a monograph of Dillenia (incl. Wormia) the latter serving as a thesis at Leiden University. He finished a revision of Malay Peninsular Argyreia and has started work on a monograph of the genus Erycibe (Convolv.). His work on Convolvulaceae is to be added to Dr S.J. van Ooststroom’s who will compile the revision of Gonvolvulaceae for Flora Malesiana.
