464 XXXVIII. SAPINDACE^. [^Atcilaya.^ 



brandies and panicles softly velvoty-tomcntose. Leaves or leaflets from 

 oblong to linear, apparently as variable as in J, heyniglauca^ but longer, often 

 above 8 in,, very much more reticulate, the common petiole jisually broadly 

 winged, the wing also much reticulate. Panicle loose. Sepals silky -pubescent, 

 about \\ lines long. Petals twice as long. Filaments hairy. Samara? softly 

 tomentosCj 2 in. long including the Aving, w^hich is fully twice as long as broad, 

 the cavity pubescent inside. — Thouinia Tariifolia^ F. Muell. Fragm. i. 4fi.

9. SAPINDUS, Linn. 



Flowxrs regular, polygamous. Sepals 4 or 5, much imbricate in the bud. 

 Petals as many, usually exceeding the sepals, wath 1 or 2 inner scales or with- 

 out any. Disk annular. Stamens usually 8 to 10. Ovaiy 2- to 4-lobcd, 

 2- to 4-cclled, with 1 ovule in each cell. Style w^ith 2 to 4 stigmatic lobes. 

 Fruit fleshy or coriaceous, divided into 2 to 4 globular or ovoid indchisccnt 

 lobes, not nmricate. Seeds without any ariilus ; eml)iyo straight or cmTcd ; 

 cotyledons thi-jk. — Trees or shrubs, rarely climbing. Leaves pinnate, rarely 

 l"foliolate. Flow^ers in terminal or axillarj^ panicles. 



The gcuus is widely dispersed over tropical regions, hut less numcroas m America thaa 

 in Asia. The Australian species is^ as far as known, endemic; but, like many others of the 

 genus, it must remain in some measm*e doubtful until the fruit has been seen, 



1. S. (?) australiSy Benth. Young branches, petioles, and ponicles 

 pale or hoary vs\i\\ a very minute tomentum. Leaflets, in our specimens, 4 

 or 6, broadly ovate, obtuse, 3 to 5 in. long, entire, often oblique, narrowed 

 into a short pctiobile, conaceous, ghibrous, much veined, of a pale, almost 

 glaucous colour. Panicle loose, longer than the leaves. Flowers shortly 

 pedicellate, in little loose cymes along the divaricate branches. Sepals in the 

 male flowers, the only ones seen, hoary-tomentose, rather above 1 line long. 

 Petals nearly 2 lines long, oval-oblong, narrowed into a short claw, pubescent 

 outside, with a single shoxi broad scale inside fringed with long hairs. Sta- 

 mens usually 8, as long as the petals. Filaments hairy,

 have referred this plant to Sapindus, from its gcueral resemblance in habit and male flowers

10. ISTEPHELIUM, Linn. 



Flowers regular, polygamous. Calyx small, cup-sliapcd, with 1 or 5 rarely 

 6 teeth or lobes, valvate or slightly imbricate in the bud. Petals none, or as 

 many as calyx-lobes, small, with a 2-cleft scale or 2 scales inside. Disk 

 annular. Stamens 6 to 10, inserted within the disk ; filaments in the Aus- 

 tralian species short, in others elongated. Ovary 2- or 3-celled, usually lohed, 

 with 1 ovule in each cell. Style with 2 or 3 stigmatic lobes. Fmit usually 

 deeply 2- or 3-lobed, or rarely entire, 2- or 3-celled, or reduced to a single 

 carpel, the lobes indehisceut or 2-valved, or opening irregularly, muricate, or 

 in the Australian species smootli. Seeds usually wTiolly or partially enclosed 

 in an arilhis ; testa coriaceous ; cotyledons thick. — Trees, wdth the habit of 

 Ciipania. Leaves abruptly pinnate; leaflets opposite or alternate, the pn-
