a separate genus has been made,^ the apetalous, dioecious flowers have 

 a small calyx and linear an- 

 thers, exserted. This genus 

 contains about fifty species,^ 

 growing in Europe and 

 North America and also 

 .abounding in temperate 

 Asia, the Himalayas, and 

 Japan. Some are also found 

 in Java. The leaves are op- 

 posite, exstipulate, simple, 

 entire, palmatilobate or 

 palmati-partite, pinnate in 

 Negundo. The flowers, 



which are precocious, axillary or terminal (green, yellow, reddish), 

 are arranged in spiciform or corymbi- 

 form clusters of cymes. 



In connection with the Maples, Dobinea 

 has been placed in this series. It is a 

 a shrub from the mountains of India, 

 having opposite simple leaves and tetra- 

 merous male flowers, diplostemonous and 

 w.ith double perianth, whilst the female 

 flower has an unilocular ovary, with a 

 descendent ovule, superior and interior 

 micropyle, and no perianth ; but the dry, 

 compressed, marginated fruit, containing a 

 seed whose embryo has flat oval cotyledons 

 and an accumbent radicle, is adnate to a 

 bract growing in a sub orbicular, membranous, veined wing resembling 

 a samara.
