8 I. RANUNCULACEyB. [Ranumulus. 



into 8, 6, or 7 segments, varying from ouneate to narrow-linear, rarely entire, 

 usually 3-lobed, and sometimes much out, but never pinnate, either quite 

 glabrous, as well as the whole plant, or rarely with a very few appressed hairs. 

 Flowers yellow, usually small, the sepals not reflexed. Petals 6 to 10, about 

 twice as long as the sepals, or 5 only in small-flowered varieties, narrow-oblong. 

 Achenes rather small and broad, with a firm or slender recurved or rarely nearly 

 straight point, not tubercled or muricate. — F. Muell. PI. Vict. i. 8. 



Hab. : Brisbane Biver. 



Var. major. Tufts erect. Leaf-segments J to lin. long or more, often very narrow and much 

 out, on petioles of 2 to 6 inches. Flowers rather large. — B. inundatus, B. Br. in DC. Syst. Veg.

4. Bu parviflorus (small-flowered), Linn.; DC. Prod. i. 42: var. australif ; 

 Betith. Fl. Austr. i. 14. A slender hairy annual, either with tufted, erect stems 

 of a few inches, or weak, procumbent, and lengthening to a foot or even more. 

 Leaves small, orbicular, the lower ones often only 8- or 5-lobed, but mostly 

 divided into three segments, either entire or B-lobed, or again cut into narrow 

 segments. Flowers small, leaf-opposed, sessile, or on short, slender peduncles. 

 Sepals rarely above 1 line long and very deciduous. Petals 5 or fewer, seldom 

 much longer than the calyx. Achenes in a small globular head, much com- 

 pressed, with a smooth margin, seldom much exceeding a line in breadth in 

 Australian specimens, the sides covered with short hairs, or tubercles, or short 

 hooked bristles, the style forming usually a very short recurved point, more rarely 

 rigid and dilated at the base. — F. v. M. PI. Vict. i. 9 ; R. sessiliflorus, E. Br. ; R.

Hab. : A common weed of moist land in Southern Queensland. 



Order II. DILLENIACE^. 



Sepals usually 6, persistent, imbricate in the bud. Petals 6 or rarely fewer, 

 deciduous, imbricate in the bud. Stamens hypogynous, indefinite, few or 

 numerous, or rarely definitely 10, free or rarely united in clusters. Anthers 

 innate or adnate. Gynoecium of carpels several, free and distinct or cohering at 

 the base, or rarely single and excentrical, 1 -celled, with 1 or more ovules in each. 

 Styles quite distinct and diverging. Fruit-carpels either indehiscent and suc- 

 culent, or opening along the inner edge, or in two valves. Seeds furnished with 

 an arillus ; testa crustaceous. Embryo very small, at the base of a fleshy 

 albumen. — Trees, shrubs, climbers, or herbs. Leaves alternate or very rarely 

 opposite. Stipules minute or none. Flowers usually yellow or white. 



A considerable Order, of which rather the larger portion, with regularly pinnate veins 

 prominent on the under side of the leaves, is entirely tropical. 



Tribe I. DelimesD. — Stamens with the filamentf more or less dilated upwards. Anthers 

 short, cells divergent or rarely parallel, leaves with parallel lateral nerves, often scabrous. 



Sepals 5. Spreading. Carpels 3 — S (rarely 1 — 2 ?), acuminate, ovules many. 

 2-Beriate. Panicles terminal 1. Tetbaobra. 



Tbibe II. JUllenieSB.— Stamens with the filaments not dilated upwards. Anthers linear or 

 rarely oblong, cells parallel contiguous. Leaves large, with parallel lateral nerves. 



Sepals 5. Anthers biporous. Carpels 5 — 10, ovules many, scarcely cohering, 

 dehiscent at maturity. Trees 2. Wormia.
