 (After John Maogregor, of Victoria.) 

 Sepals 5, narrow-lanceolate, imbricate in the bud, free, persistent. Petals 5, 

 almost hypogynous, free, membranous, alternate with the sepals, imbricate in the 

 bud, oblong or obovate, spathulate, deciduous. Stamens 5, alternating with the 

 petals. Filaments free, very short. Anthers linear-oblong, straight, introrse, 

 basifixed, 2-celled, dehiscing longitudinally. Pollen-grains oval, very smooth. 

 Stigmata 5, very short, sessile, linear-subulate. Cocci 5, superior, obovate, 

 indehiscent, 1-seeded. Columella very short, the upper membrane ample. 

 Pericarpum very thick. Seeds erect from basil cavities at base. Albumen fleshy. 

 Embryo pyriform, straight, scarcely shorter than the albumen. Cotyledons- 

 plano-convex. Eadicle short, inferior. A glabrous annual with but few linear 

 leaves and terminal racemes of flowers. — F. v. M. Fragm. viii. 160. 



1. IME. racemigera (flowers in racemes), F. v. M. Fm0i:^-vm. 161 ; Hook. Jc. 

 1230. A small, erect, or ascending branched herb. Leaves quiJ?Bntire, somewhat 

 acute, slight narrowing to the base, J to fin. long, J to | line broad. Pedicels very 

 slender, 1 J to 4 lines long. Sepals about 1 line long, with a very narrow membranous 

 margin, joined together only just at the very base. Petals 3 to 5 lines long, 

 narrowing to a rather long base. Anthers ^ line long, light-yellow, terminated 

 by a very small, oval, white appendage. Cocci scarcely ^ line long, sprinkled 

 with very short hooked hairs. Testa shining, smooth, and marked with very fine 

 dots. Embryo yellowish. — F. v. M., I.e.

Order XXXVIII. RHAMNE^. 



Flowers regular, hermaphrodite, or rarely polygamous. Calyx campanulate, 

 urceolate, or cylindrical, the tube persistent and often adnate to the ovary or disk ; 

 lobes 4 or 5, valvate, usually with a raised longitudinal line inside, and deciduous. 

 Petals 4 or 5, concave or hood-shaped, inserted at the base of the calyx-lobes, 

 alternating with and rarely exceeding them, or none. Stamens 4 or 5, alternating 

 with the calyx-lobes, inserted with the petals and opposite to them when present ; 

 filaments short, filiform ; anthers small, often enclosed in the petals, rarely 

 oblong or exserted. Disk rarely wanting, usually filling the calyx-tube or lining 

 it, or annular round the ovary when inferior, rarely cup-shaped and free. Ovary 

 sessile on the disk or immersed in it, or more or less inferior, 3-celled, or rarely 2 

 or 4-celled ; style short, entire, or with as msRiy lobes or branches as ovary-cells ; 

 stigmas terminal, capitate or club-shaped. Ovales solitary in each cell, erect, 

 anatropous, with a dorsal or rarely lateral raphe. Fruit a drupe or capsule, the 

 border of the adnate base of the calyx forming a ring at the base or round the 

 fruit or at the summit ; epicarp thin and dry or fleshy ; endocarp separating into 

 as many membranous coriaceous or hard cocci as cells, or woody or bony, divided 

 into cells. Seeds solitary, erect, usually ovate and somewhat compressed, often 

 arillate ; testa coriaceous or erustaceous and shining or rarely membranous ; 

 albumen fleshy or almost horny, often scanty, rarely wanting ; embryo usually 

 straight, with flat rather thick cotyledons and a short inferior radicle. — Shrubs 

 or trees, very rarely, in genera not Australian, herbs, erect or climbing. Leaves 

 alternate or rarely opposite, undivided, entire, or toothed. Stipules usually 

 present but very deciduous, rarely spinous an.d persistent. Flowers small, usually 

 green or yellowish, in cymes or umbel-like clusters, either solitary or forming 

 axillary or terminal compound cymes, racemes or panicles. 



A considerable Order, ranging oier the tropical and temperate regions of both the New and 

 the Old World. Of the 12 Australian genera, 3 are widely spread tropical or northern genera, 

 and 1 tropical Asiatic, all represented in Australia by single or very few species, a fifth is South
