[Sapindacea. 
than 1 line, with a minute point, of a much paler color than in most other Dodonsea. Styles 3-4 united 
into one, viscidulous, about \ inch long*, twisted, free at their acute apex. Capsule inconsiderably longer 
than broad, 3-4 lines long, subcoriaceous or chartaceous, not so brittle or scarious as in many congeners, 
remarkable for not throwing the valves off from the septa, but the former, when dropping, carrying the 
latter and the seeds with them, leaving merely the columna and funicles persistent. Seeds measuring about 
1 line, oblique-lenticular, at first brown, at last black, covered with a wrinkled pellicle, often retained in the 
falling cells of the capsule, inasmuch as the two plates of the dissepiment belonging to each carpel are not 
generally bursting with a wide fissure along their axil suture. 
The species nearest to this seems to be D. trigona (Lindl. in Mitch. Trop. Austr. 236). I). Lindleyana 
(D. triangularis, Lindl. in Mitch. Trop. Austr. 219; D. mollis, Lindl. 1. c. 212) differs in narrower anthers 
and in the fruit, which is otherwise very similar, having' the septa persistent with the column.

Uodonaea stenozyg-a, F. M. Fragm. Pliyt. Austr . i. 98. 
Glabrous, slightly viscid; leaves pinnate , rarely a few simple; rachis narrorv-semiterete , wingless, 
channelled; leaflets emanating' towards the summit of the rachis, few, rarely several, alternate and opposite , 
remote , short , linear , entire, blunt, concave above, convex beneath ; pedicels of the female flowers axillary, 
solitary, geminate or ternate, about as long as the fruit; sepals oblong-lanceolate; style short; capsule 
sliort-stipitate, 4-5-valved; valves seceding from the septa; wings blunt on both extremities, winged from 
the summit to the base, upwards dilated and broader than the valves; septa dimidiate-ovate; seeds opaque, 
gradually compressed towards the margin; cotyledons somewhat longer than the radicle. 
In the desert near the confluence of the Loddon with the Murray River. J. Dali achy. 
A compact shrub, a few or several feet high, with numerous branches and slender branchlets. Rachis 
measuring J-l inch in length, and less than 1 line or generally only about *£ line in width ; its lower pari 
without leaflets, forming a long spurious petiole. Terminal leaflet in most cases diminutive or undeveloped; 
lateral leaflets either forming a single pair at the apex of the rachis, thus giving to the wdiole leaf a furcate 
form, or fev r or several, never more than about a dozen in number, rather distantly disposed along a rachis, 
in width and consistence similar to the latter, but generally" less distinctly channelled, sometimes nearly flat, 
mostly- from 3-9 lines long. Flowers seemingly 1 " dioecious; male ones unknown ; peduncle of the female ones 
either very- short or wanting; pedicels generally r veiy spreading or deflexed, inch long, slender-filiform, 
gradually thickened towards the apex. Sepals slightly downy, about 1 line long, early r dropping. Style 
IJ-2 lines long, dark-red, filiform. Stipes of fruit always evidently' developed, sometimes in smaller fruits 
only- abofrt \ line long, sometimes in larger fruits even somewhat more than 1 line long, cylindrical, scarcely 
thicker than the summit of the pedicel, from which it is separated by articulation. Consistence of the capsule 
that of D. viscosa. Valves 3-6 lines long', with semicircular sides, shining. Wings scarious, often purplish, 
according to the size of the fruit 1-2 lines broad towards the summit. Seeds hardly 1 line long, rendered 
by- the firmly- adnate pellicle opaque, after the removal of which the perfect splendor of the testa becomes 
easily perceptible. Embry-o alike to that of D. viscosa. 
It is more than probable that this curious plant will prove merely a pinnate-leaved variety of D. acerosa 
(Lindl. in Mitch. Trop. Austr. 273; D. filifolia, Hook. 1. c. 241), a question which, however, cannot be set 
at rest, until the male flowers are availabl^for comparison. D. tenuifolia (Lindl. in Mitch. Trop. Austr. i. 
248) is, according to the brief diagnosis, near to our plant if not identical with it. D. adenopliora (Miq. in 
Lehm. PI. Preiss. ii. 235; Thouinia adenopliora, Miq. 1. c. i. 224) differs, as far as the material within our 
reach admits judging of, in having the rachis with regularly- opposite and closely approximated leaflets foliate 
to near the base and in shining seeds.
