often more or less folded. — Trees or shrubs. Leaves alternate, coriaceous, entire, 

 the primary veins not so prominent as in Briedclia, arcuate and anastomosing 

 far within the margin, the veinlets reticulate, not transverse. 



The genus extends, like Brieclella, over the warmer regions of Africa, Asia, and the South 

 Paeifio islands, hut the Australian species appear to be all endemic. The abortion of the 

 floral leaves in many species gives them a peculiar iufloressenoe, different from that of any 

 other Australian Phyllaiithete. 



Flower-clusters all axillary, small. Leaves mostly under 2in. Stamens 

 very shortly united. 



Capsule stipitate. Leaves obtuse 1. C GunningTiamii. 



Capsule sessile. Leaves mostly acuminate 2. C apodui. 



Flower-clusters mostly in leafless interrupted ferruginous spikes. Leaves 

 above 2in. long. Staminal column as long as the filaments. 

 Calyx-segments IJ line long. Leaves green on both side. Capsule 



glabrous 3. C, Dallachyamis. 



Calyx-segments scarcely 1 line long. Leaves pale or glaucous under- 

 neath. Young capsule villous i. C. semiopamis. 



1. C. Cunninghamii (after A. Cunningham), F. v. M. Arg. in DC. Prod. xv. 

 ii. 503 ; Benth. Fl. Aitstr. vi. 122. A tall shrab, quite glabrous or the young 

 shoots slightly pubescent. Leaves petiolate, ovate-oblong or elliptical, rather thinly 

 coriaceous, obtuse or rarely obtusely and obscurely acuminate, mostly 1^ to 2in. 

 long, often glaucous underneath. Flowers in dense axillary clusters, sessile or 

 nearly so. Male calyx glabrous. Petals small, obovate-cuneate. Stamens 

 very shortly united at the base. Female calyx with a broadly turbinate base, 

 the lobes spreading, under 1 line long. Disk lining the turbinate base and 

 produced into a hhort cup round the ovary. Ovary very villous, the tapering 

 base half included in the base of the calyx. Styles rather long. Fruit depressed 

 globular, tridymous, at first very villous, but becoming nearly glabrous when 

 ripe, borne on a stipes usually exceeding the calyx but variable in length. —

2. C. apodus (stalkless), Bentli. Fl. Aicstr. vi. 122. ■' Gillowari," Barron 

 Eiver, F. Coirley. A straggling .shrub or small bushy tree, usually quite 

 glabrous, nearly resembling C. Cunninrjliamii, but the leaves more ovate, and 

 usually acute or acuminate, the male flowers rather smaller, the calyx-segments 

 scarcely above 1 hne long, the female calyx-lobes broader, 1 line long. Ovary 

 hirsute with a few long hairs. Styles united at the base in a short column, the 

 bifid branches spreading. Capsule closely sessile within the persistent calyx, 

 quite glabrous, 8 to 4 lines diameter.

3. C. Ballachyanus (after ,T. Dallachy), BaiU. in Herb. F. v. M. ; Benth. 

 Fl. Anstr. vi. 122. A handsome tree, the inflorescence and sometimes 'the 

 young shoots ferruginous pubescent, the adult foliage glabrous. Leaves ovate- 

 obtuse or more frequently obtusely acuminate, rounded at the base, rather 

 thickly coriaceous, shining above, scarcely glaucous underneath, mostly 2 to 4in. 

 long. Flowers sessile in sessile clusters, which are sometimes distant in the axils 

 of floralleaves of ^ to lin., more frequently nearer together and from the abor- 

 tion of the floralleaves, forming more or less interrupted spikes of 1 to. Sin. 

 Bracts small but very broad, obtuse and concave, enveloping the buds, ferrugi- 

 nous-villous as well as the rhaohis. Jlalo calyx glabrous, the segments rather 

 thin, 1| line long. Petals not half so long, very broad and more or less
