[Sapindacece. 
base, acuminate, acute or rounded-blunt or truncate or emarginate at tlie apex, flat or recurved at tlie margin, 
j§-6 inches long, J-l J inch broad, one-nerved, faintly or prominently veined, the primary veins being almost 
parallel-divergent from the midrib, glabrous, seldom in a young state downy, more or less distinctly dotted, 
in rare instances pinnate; the rachis then sometimes similar to the ordinary state of the leaf, the leaflets J-1 
inch long, acute, flat, few or numerous, alternate or opposite. Inflorescence terminating the branchlets, 
consisting of few or many flowers, short-pedunculate. Pedicels capillary-filiform, when flower-bearing 1 or 
a few lines long, when fruit-bearing often extending' to several lines, provided at or near the base with a 
short linear deciduous bracteole. Sepals about 1 fine long, lanceolate-ovate or lanceolate, rather acute, very 
slightly downy, viscid, deciduous. Anthers somewhat tetragonous, yellow or reddish-purple, minutely apicu- 
late, glabrous or very slightly bearded at the apex. Pollen-grains globose-ovate, bursting lengthwise. Styles 
3, united into one, which is setaceous, yellowish or brownish-red, J-4 lines long; the acute apex free, or 
occasionally the styles deeply separating. Size of fruit subject to considerable variations, measuring, inclusive 
of the wings, from 4-8 lines across, and almost as much in length. Valves thin-crustaceous or chartaceous, 
with semiorbicular sides; their edges meeting the margin of the septa. Wing-s scarious, veined, yellowish 
or purplish, somewhat narrower towards the base than towards the apex, occasionally nearly twice as broad as 
the valves. Seeds affixed like in the congeners to very short funicles at the middle of the internal angle of 
the cell, 1-1J line long, smooth, roundish or lenticular-ovate, opaque, sometimes quite shining, rather turgid, 
somewhat acute at the edge. Hilum conspicuous, fulvous. Testa subcoriaceous. Endopleura membranous. 
Embryo cream-colored, coiled up in many windings, circinate. The radicle cylindrical, thickened gradually 
towards the blunt extremity; the cotyledons about twice as long as the radicle, flat, linear, narrower towards 
the apex. 
The greater part of the described extra-Australian species may be referable to this plant. D. triquetra 
differs in being hardly resinous-viscid, having hence its leaves opaque, in more decidedly compressed 
branchlets, in generally longer pedicels, in male flow r ers with remarkably short sepals and long anthers, in a 
very elongate style, in wings hardly as broad as the valves and in always very shining seeds, surrounded by 
a very tender brittle diaphanous pellicle. 
D. cuneata seems only a variety of D. viscosa, characterized by w r edge-shaped leaves. 
D. lobulata, which extends from Lake Torrens to the Gardiner Ranges in Western Australia, may 
only be a state of D. viscosa, inclined to produce leaflets, which however are reduced to mere minute teeth; 
the flow r ers, however, of this plant are as yet undiscovered. 
Beautiful pinnate-leaved specimens of D. viscosa w r ere collected by Dr. Beckler in the wmim damp 
forest valleys of the IIasting*s River; in this curious variety, which may be designated megazyga, the valves 
of the fruit remain small, and the seeds almost constantly undeveloped, whilst the foliage so remarkably 
luxuriates. To Mr. Woolls w r e ow r e a specimen of D. viscosa, found at Parramatta, which exhibits on the 
same branchlets simple and pinnate leaves and their intermediate forms. 
The stout D. Burmanniana is evidently only another state of the polymorphous D. viscosa, being a 
progeny of the tropical zone, with more vigorously developed almost coriaceous leaves, wliich are strongly 
spreading'-veined, and with predominantly hermaphrodite flow r ers. This variety retains its characters in 
cultivation. It occurs in forms perfectly analogous to those of India in humid localities of the w r arm eastern 
tracts of Australia. 
Dodonaea procumbens, F. M. in Transact Phil Soc. Viet i. 8. 
Dwarf, diffuse or procumbent, hardfy viscid; leaves subchartaceous, cuneate, flat, generally with a few 
coarse acute teeth at the apex; pedicels rather short, erect, terminal; those of the female flowers solitary, 
occasionally geminate or ternate; flowers dioecious; sepals generally 5, lanceolate, about as long as the 
ovate-oblong anthers; filaments very short; style much elongated ; * cap) sides wingless , 2- or 3-valved; 
somewffiat longer than broad, dissepiments dimidiate lanceolate.
