The oitiin- ary name uf the Mani- toba tree (Ash-leaved Maple) is based upon this difference in the structure of the leaf. The Maples form a subordinate group of the natural Order Sapindaceo'^ They are distinguished by the following characters : 1. The /lowers are dioBcious (or polygamo-dicecioue), and cotnmonfi/ uiisymmetrical. ii. The ovary is tioo-lobed and two-celled, ivith two tivtdes in each cefl, only one of which, hotvever, is ripened. S. The/mil is a double samara. 4-. The halves arp opjiosite. 62. From this type there are important deviations in other representatives of the Order. , for instance, pi-o<luces a three-celled ovary, with two ovules in each cell; but as in Maple, again, ripens only one of each pair. The fruit, too, is not a samara, but a leathery pod, containing the three large shining seeds.
