258 MR. J. G. BAKER OX THE 



has 12 species of Antherieum, 2 of Chlorophytum, 2 of Nartheciutn, 

 and four monotypic genera (Echeandia, Bottincea, Pasithea, and 

 Eccremis), in all twenty species, against 241 for the Old World. 

 In Narthecium, we have four very closely allied forms, here treated 

 as species, representing one another in four different geographical 

 areas of the north temperate zone, Europe, Japan, California and 

 the Atlantic States. Five of the genera (Antherieum, Asphodelus, 

 Paradisea, Asphodeline, and Morgagnia) are represented in the 

 European flora ; Asphodeline belongs to the Mediterranean and 

 Oriental region, and Eremurus (with eighteen species) belongs to 

 Central Asia. There are three monotypic genera in North Asia 

 and Japan, Selonia, Anemarrhena and Metanarthecium. Eight 

 genera, containing about fifty species, are nearly or quite endemic 

 in Australia ; Bulbine belongs to both the Cape and Australia ; 

 and there is one species in tropical Africa of the otherwise Aus- 

 tralian genus Ccesia. Chlorophytum, with 35 species, belongs almost 

 entirely to tropical Africa and tropical Asia ; Eriospermum belongs 

 entirely to the Cape and Tropical Africa ; and it is at the Cape we 

 have the greatest concentration of the two large genera Antheri- 

 eum and Bulbine, but not a single endemic genus.
