imbricate in the bud. Filaments 4, flattened, longer than the petals, arching 

 over the ovary. Anthers connivent, somewhat cordate, rather large. Ovary with 

 8 prominent wing-like angles. Stigma sessile. 



Hab.: Johnstone Kiver, Dr. Thou. L. Buiirroft, who reports the wood and bark to be 

 poisonous ; Barron Biver, E. Cowley. 



Wood yellow, of close grain, and easy to viovk.— Bailey's Cat. Ql. Woods No. 44a. 



The bark possesses a poisonous principle as toxic as strychnine, to whose physiological action 

 it has some resemblance. ~T. L. Bancroft. 



3. Z. torvum (unapproachable), F. c. M. Fragm. vii. 140. A tall scrub 

 climber, the stems often several inches thick and arriied with similar prickles to 

 the other species. The branchlets, petioles, and peduncles clothed with a very 

 short cano-fuscus pubescence and prickles. Leaves impari-pinnate. Leaflets 5 

 to 9, subcoriaceous, 3 to Sin. long, ovate, very shortly petiolulate, oblique, rounded 

 at the base, somewhat long and obtusely acuminate, the margins with distinct 

 bristle-like teeth, both sides glabrous and glossy. Panicles about 4in. long, 

 shortly branched. Pedicels about as long as the flowers. Bracteoles at the base 

 of the pedicels, very minute, linear- subulate. Petals imbricate, lanceolate-ovate, 



1 line long, base truncate, yellow. Filaments of the male flower setaceous, 

 almost 2 lines long. Anthers cordate-ovate, dorsally attached. Ovary of female 

 flowers 4. Styles very short, coherent. Stigmas united into 1, peltate, 4^3, 

 maturing 2 — 1, scarcely 8 lines, compressed, almost lenticular, obtuse. Seeds 

 \\ line, ovate-globular, glossy black, solitary. 



Hab.: Many of the northern range scrubs. 



Wood yellow and close-grained. — Bailey's Cat. Ql. Woods No. 44. 



4. Z. parviflorum (small-flowered), Benth. Fl. Amtr. i. 863. A small tree, 

 glabrous and unarmed, or with very few minute distant prickles. Leaves pinnate, 

 with a common petiole of 4 to 6in., angular but not winged ; leaflets usually 9 to 

 11, opposite in pairs, the terminal odd one occasionally wanting, ovate-lanceolate, 

 acuminate, rarely above 2in. long, entire or slightly denticulate, usually oblique, 

 the upper edge most rounded at the base, membranous or at length scarcely 

 coriaceous. Panicles terminal, 3-chotomous, broad, with numerous small 

 4-m6rous flowers. Sepals small, triangular. Petals scarcely IJ lines long, 

 slightly imbricate. Stamens in the males 4, about as long as the petals. Ovary 

 rudimentary, of 1 or 2 carpels. Female flowers not seen. Cocci solitary, 8 to 4 

 lines long, coriaceous, rugose outside, opening broadly to below the middle in 



2 valves, endocarp persistent. Seeds with a hard bony testa enveloped in a thin 

 black shining epiderm. 



Hab.: Islands of the Gulf of Carpentaria. 



16. GEIJERA, Schott. 



(After J. D. Geijer.) 



Flowers hermaphrodite. Sepals 4 or 5. Petals 4 or 5, valvate or imbricate. Disk 

 thick and fleshy. Stamens 4 or 5 ; filaments subulate. Ovary depressed, partly 

 immersed in the disk, 4 or 5-lobed ; styles terminal, immediately united into a single 

 short style, with a capitate 4 or 5-lobed stigma. Fruit of 4 or 5 or sometimes fewer 

 distinct, 2-valved cocci, the endocarp adherent or partially separating. Seeds 

 with a hard or crustaceous shining testa ; albumen fleshy ; embryo straight ; 

 cotyledons broad. — Trees or shrubs. Leaves alternate, simple, not articulate on 

 the petiole. Flowers small, in terminal panicles. Sepals small. 



The genus is limited to Australia, and differs from" Zanthoxylum chiefly in the simple leaves 

 and hermaphrodite flowers. — Benth.
