globular. Valves 1J-4 lines long, verging from a rhomboid or dimidiate-orbicular into an ovate form, almost 
cartilaginous, outside, except the margin, greenish, inside shining', connate sometimes only near the inner 
edge, sometimes to nearly the outer margin, the concrescence not rarely so permanent as to render the fruit 
loculicidal-capsular, then one valve of two adjoining carpels seceding from the fruit-axis without mutual 
dissolution. Central column conical towards the base, stout- or slender-cylindrical upwards, persistent, 
always angular. Seeds line long, ovate-roundish, with an imperfect narrow sinus from the base upwards, 
rough through elevated transverse lines, glabrous. Strophiole line long, pallid, cellular, somewhat 
fleshy, obconical with faint lobes. Testa finally dark-brown. Embryo almost annular in an elliptic line. 
Albumen, if developed, lying solely in the sinus of the embryo. 
The specimens collected in North-Western Australia, on Sturt’s Creek, show only male flowers, and 
are remarkably narrow-leaved and slightly viscid, the plant thus assuming the appearance of a Dodoncea. 
D. tkesioides, from which D. Drummondi, according to Moquin’s description, seems not distinct, differs 
principally in a four-cleft calyx and in a dicarpellar fruit. At an average its anthers are neither so numerous 
as in D. pleiococca.

CODONOCARPUS. 
All. Cunningh. in Hook. Bot. Misc. i. 244. 
Flowers dioecious. Calyx meniscoid, repand or few-toothed. Corolla wanting. Male flowers: 
Anthers 14-20, uniseriate , subsessile, basifixed, arranged around rudimentary pistils. Female 
flowers: Ovaries numerous, concrete around a central column. Ovules solitary, ascendent from the 
inner angle of the ovary. Styles numerous, continuous to the placental edges of the fruit-axis, subulate, 
stigmatose, persistent. Carpels numerous , completely coherent into a campanulate-obconical fruit; 
those of the outer series fertile, secedent, membranous, flat, bursting at the inner edge. Column 
towards the sunvmit much dilated and at the vertex concave and stigmatose by the indurated 
coalescence of imperfectly developed inner series of carpels. Seeds affixed near the summit of the 
column, strophiolate. Testa crustaceous. Embryo uncinate-annular, cylindrical, surrounded by very 
scanty fleshy albumen. Radicle hardly longer than the cotyledons. 
Small trees, peculiar to extratropical and subtropical Australia. Leaves carnulent, opaque, 
entire. Stipules exceedingly minute. Male flowers collected into leafless racemes . Female flowers 
solitary or racemose. Bracteoles exceedingly minute, geminate at the base of the pedicels.— Endl.

Gyrostemon, reduced on this occasion to the earliest published species (G. ramulosus, Desf. in 
Mdm. du Mus. vi. 17, t. 6.) differs generically from Codonocarpus in axillary solitary male flowers, in 
pluriseriate anthers, occupying the whole bottom of the calyx, thus not admitting of the development 
of rudimentary pistils, in a single whorl of carpels, the column being consequently neither thickened 
into a large turbinate nor at the vertex stigmatose summit, in bivalved completely dehiscent carpels, 
in which the seed is lodged near the bottom of the cavity. The indistinct formation of inner 
pistils is not peculiar to Codonocarpus, traces of the same organization being manifest in Tersonia, in 
which genus moreover the arrangement of the fertile styles and their form is akin to Codonocarpus.
