LXVIII. SAPINDACE^. 353 



[Sub-orders, tribes and genera of Sapindacew according to the authors of the 

 * Genera Plantarum' : 



"Sub-order I. SAPINDEJ;. Stamens inserted within the disk, around the base of tho ovary, 

 or unilateral. Seeds exalbuminous. Leaves rarely opposite. 



A. Flowers usually irregular and 4-petalous. Disk unilateral or very oblique. 



* Ovules solitary. Urvillea, Serjania, Tmilicia, Cardiospermum, Paullinia, Hemigyrosa, 

 Erioglossitm, Schmidelia, &c. 



* * Ovules 2 or more in tbe cells. Koelreuteria, Cossignia, dEsculus, Uugnadia, Stocksia, 

 Diplopeltis, Mngonia, &c. 



B. Flowers regular or nearly so. Disk complete. 



* Ovule usually solitary. Fruit capsular. Cupania, Thouinia, Ratonict, Atalaya, &c. 



* * Ovule solitary. Fruit indehiscent, not lobed. Talisia, Hippobromiis, Melicocca, 

 Schleichera. 



* Ovule solitary. Fruit indehiscent, deeply lobed, or of 1-3 cocci. Sapindus, Euphoria, 

 Capura, Pappea, Deiribollia, Pometia, Nephelium, Heterodendron. 



* Ovules 2 or more. Harpullia, ? Hypelate, Xanthoceras, Llagunoa. 



Sub-order II. ACERINE.S. Flowers regular. Sepals and petals (when present) isomerous. 

 Stamens variously inserted. Ovarian cells 1-2-ovuled. Fruit with indehiscent lobes. Seeds 

 exartllate, albuminous. Leaves opposite. See order Acerinece, p. 354. 



Sub-order III. DODONE^S. Flowers regular. Sepals and petals (when present) isomerous. 

 Disk or complete. Stamens inserted outside the disk (when present), or between its lobes. 

 Ovarian cells 1-2-ovuled. Fruit various. Seeds albuminous. Leaves very rarely opposite. 



Dodoncea, Alectryon, Distichostemon, Pteroxylon, Alvaradoa, Aitonia. 



Sub-order IV. MELIANTHE^E. Flowers irregular. Stamens inserted within the disk, 

 hypogynous. Seeds albuminous Embryo straight. Leaves opposite. See order Melianthece, 

 p. 358. 



Sub-order V. STAPHYLE.E. ^-Flowers $ , regular. Stamens inserted outside the disk at 

 its base. Seeds albuminous. Embryo straight. Leaves opposite. See order Staphyleacecp, 

 p. 344. ED.] 



This family is very closely allied to Acerinea and Malpiyhiacea, as well as to Hipjwcastanece and 

 Staphyleacece (see these families). It has equally an affinity with Melianthece, which only differ in their 

 albuminous seed. 'Through Staphyleacece it is also connected with Celastrinece ; but is distinguished from 

 them by its generally compound leaves, often irregular flowers, rarely isostemonous petals, stamens in- 

 serted within the disk, 1 calyx with free sepals, and generally curved embryo. 



Sapindacece abound in tropical regions, especially in America ; they are rare beyond the tropic of 

 Capricorn, and have not yet been observed north of the tropics, except in the North of China and in 

 India (Xanthoceras 2 ) ; Dodcmcea abounds in Australia. 



Sapindacea; possess very various properties. Many contain astringent and bitter principles, sometimes 



1 They are inserted outside the disk in Dodoncea and 2 Koelreuteria, Stocksia, Ungnadia, Cardiospermum, 



other undoubted Sapindacea. ED. and Sapindus offer other exceptions.
