oblong-spathulate, obtuse, rather thick, flat or with recurved margins, 2 to 

 near 6 lines long. Flowers apparently dioecious, solitary on pedicels of 1- 

 to I5 line. Male perianth tubular, 2 lines long, narrow, slightly dilated 

 upwards, with 6 very short broad thick rounded and inflexed lobes, the 2 or 3 

 inner ones still smaller than the outer ones. Anthers connate, occupying rather 

 more than half the length of the staminal column, the connective scarcely pro- 

 jecting beyond the cells. Female flowers much smaller, the perianth-segments 

 short and spreading. No disk. Ovary glabrous, 3-celled, with 3 short thick free 

 styles, spreading at the end but not lobed. 

 Hab.: Near Brisbane Eiver and other southern localities to Springsure. 



2. P. hirtellus (hairy), Miiell. Arg. in DC. Prod. xv. ii. 326 ; Benth. FL 

 Austr. vi. 98. Apparently herbaceous, or perhaps an undershjrub, the stems 

 not above 6in. long, slender,, minutely-pubescent as well as the foliage. Leaves 

 distichous but rather distant, linear or oblong, mostly somewhat cuneate, J to- 

 l^in. long. Stipules very minute. Flowers mostly solitary, the males on pedicels. 

 of 1 to IJ line. Perianth-tubular, nearly 2 lines long, narrow, slightly dilated 

 upwards, with 6 broad lobes not ^ as long as the tube, 2 of the inner ones smaller 

 than the others. Anthers connate, occupying about half the length of tha 

 staminal column, the connective very slightly projecting beyond the cells. 

 Female flowers on pedicels of 1 to 2 lines or sometimes 3 lines when in fruit. 

 Perianth divided to the base into ovate very obtuse segments of nearly f line. 

 Styles united at the base, shortly free, broad and spreading at the top. Capsule 

 ovoid, pubescent, 4 or 5 lines long. — Synostemon hirtellus, F. v. M. Fragm. iii. 89. 



Hab.: Bookhampton, Connors Eiver, Walloon, Bmoman; Brisbane Biver. 



3. P. rigens (stiff), Muell. Arr/s in Flora 1864, 518, and in DC. Prod. 

 XV. ii. 825 ; Benth. FL Austr. vi. 99. Probably a small shrub, with rigid 

 terete branches quite glabrous and perhaps spineseent. Leaves very small, 

 clustered at the nodes, obeordate or cuneate and emarginate, rather thick, 1 

 to 8 lines long. Male- flowers sessile. Perianth-segments connate high up, 

 ovate, obtuse; anthers connate, with the connective projecting beyond the 

 cells. Female flowers on slender pedicels much longer than the leaves. 

 Perianth-segments linear, rigid, rather above 1 line long. Ovary glabrous, 

 contracted at the top. Styles 3, very short, spreading, rather broad, entire or 

 notched. Capsule glabrous, 8 to 4 lines long. — Synostemon riyens, F. v. M. 

 Fragm. ii. 153. 



Hab.: Aramao and other southern localities. 



4. P. ramosissimus (much branched), Muell. Arg. in Linncea xxxiv. 70> 

 and in DC. Prod. xv. ii. 826 ; Benth. FL Austr. vi. 99. A slender wiry rigid 

 much-branched undershrub of about 1ft,, leafless or nearly so at the time of 

 flowering. Leaves few and only on the very young branches, linear, thick, 

 almost terete, 2 to 4 lines long. Stipules small but persistent. Male flowers 

 sessile or nearly so. Perianth-segments ovate, about i line long. No glands. 

 Anthers 3, connate, occupying nearly the whole of the column. Female flowers 

 on pedicels varying from 2 to 6 lines, solitary or 2 together. Perianth 

 narrow, about 1 line long. Ovary glabrous. Styles free, thick, dilated and 

 shortly 2-lobed at the end. Capsule ovoid, 3-celled, 8 to 4 lines long. — 

 Synostemon ramosissiiaus, F. v. M. Fragm. i. 33. 



Hab.: Mackenzie Eange, F. v. Mueller ; and towards Cooper's Creek, Beckler. 



5. P. albiflorus (flowers white), F. v. M.; Muell. Arg. in Linnaa, xxxiv. 

 70, and in DC. Prod, xv. ii. 326 ; Benth. FL Austr. vi. 100. A much-branched 

 glabrous shrub, varying from 3 or 4ft. to twice that height, the branches terete 

 or slightly angular, the smaller ones slender but rigid. Leaves obovate-oblong
