FLORA OF THE HAWAIIAN ISLANDS. 175 



flowers. Fruit when ripe moderately 3-winged or angled, about 5" in 

 diameter. 



Dry hills, district of Waianse, Oahu. 



2. G. ORBICULARIS Walp. (Enum. No. 89.) An upright or de- 

 cumbent shrub at once distinguished from No. 1, by having no ten- 

 drils, by the rather thickish oval or orbicular, obtuse or even retuse, 

 short petioled leaves which are entire, or nearly so, and by the 

 younger branches, leaves, &c., being silky pubescent. The small axil- 

 lary cymes scarcely longer than the petiole. Fruit much as in the last 

 but scarcely as large. A Var. has the petioles longer than the leaves 

 and the peduncles of the cymes equalling them, and broader wings to 

 the fruit. 



Sandy Isthmus of Maul. Lanal. The For. from Hawaii. 



ORDER XXII. SAPINDACE^. 



Trees, shrubs, or climbers with tendrils (rarely herbs), with sim- 

 ple or compound leaves ; the sepals and petals imbricated in aestiva- 

 tion. Stamens 5 - 10, inserted on a fleshy perigynous or hypogynous 

 disk. Ovary 2-6-celled, and lobed, with one or two ovules in each 

 cell ; the embryo curved or convolute and without albumen. 



1. DODONJEA Linn. [Alii.] 



Flowers polygamous or unisexual, often dio3cious. Sepals 5 or 

 fewer, valvate in the bud. Petals none. Disk small. Stamens usu- 

 ally 8, sometimes fewer, rarely 10; filaments very short. Ovary 3-4-, 

 rarely 5 - 6-celled, with two ovules in each cell : style short, or in some 

 flowers very long, lobed at the end. Capsule membranaceous or coria- 

 ceous, opening septicidally in as many valves as cells, each valve with 

 the dorsal angle often produced into a vertical wing, and in falling off 

 leaving the dissepiment attached to the persistent axis, or rarely the 

 dissepiments splitting and remaining attached to the valves, thus 

 closing the carpels and leaving only the central filiform axis persis- 

 tent. Seeds 1-2, with a thickened stalk, but not arillate; testa crus- 

 taceous ; embryo spirally curled. Shrubs, often arborescent ; the 

 young shoots usually viscid. Leaves simple, or pinnate with small 

 leaflets, with or without a terminal odd one. Flowers small, axillary 

 or terminal, solitary, clustered, or in short racemes or panicles. 



With the exception of the Hawaiian species, the first of which Is widely dispersed over 

 almost all hot countries, one from South Africa, and one or two from Mexico, the species 

 of the genus to the number of about 40 are all endemic In Australia. 



1. D. VISCOSA Linn. (Enum. No. 90.) A shrub 2 -25 high, 

 glabrous, and more or less viscid, the young branches frequently com-
