MINOR NOTICES 



Das Pflanzenreich. 1 — Part 46 is a monograph of the Menispermaceae by 

 Professor Ludwig Diels. The author devotes about 45 pages to a general 

 consideration of the family and then establishes 8 tribes which are based largely 

 on the presence or absence of albumen and the character of the endocarp. 

 These 8 tribes embrace 63 genera and 357 species; and approximately one-fifth 

 of the total number of species are new to science. Tw t o new r genera are added, 

 namely Platytinospora, based on Tinospora Buekholzii Engl, of tropical Africa, 

 and Sinomenium, based on Cocculus diver sifolius Miq. of Asiatic distribution. 



Part 47 continues the monographic treatment of the Euphorbiaceae by 

 Professor Ferdinand Pax, including only the tribe Cluytieae. The author 

 divides the tribe into four subtribes, namely Codiaeinae, Ricinodendrinae, 

 Cluytiinae, and Galeariinae, depending on the number of stamens and the 

 free or united petals. The tribe embraces 24 genera and about 150 species, 

 22 of which are new to science. One new monotypic genus (Uranthera Pax & 

 Hoffm.) is proposed from the Malayan Peninsula. This part also includes an 

 elaboration of the Cephalotaceae by Professor J. M. Macfarlane. Only one 

 monotypic genus of this family is known at the present time, namely Cephalotus 

 from West Australia. 



Part 48 continues the monographic treatment of the Araceae by Professor 

 A. Engler, and contains the subfamily Lasioideae to which are referred 18 

 genera and upward of 130 species, 18 of which are here published for the first 

 time. One new genus (Dracontioides) is described, based on Urospatha 

 dehiscens Schott of southern Brazil. Amorphophalliis is by far the largest 

 genus, being represented by about 75 species or more than one-half the total 

 number recorded for the entire subfamily. Numerous and excellent illustra- 

 tions amplify the text. 



Part 49 contains a supplement to the Monimiaceae by Dr. Janet Perkins, 

 and records the results of a continued study of this family from new material 

 represented in the leading European herbaria, particularly the Berlin herbarium
