8. C. suberosa (corky), Olt. and Dietr.; Mij. liev. Can. 64, t. 6, and in DC. 

 Prod. xvii. ii. 837 I Benth. Fl. Aitstr. vi. 127. A tree of 80 to 40ft,, the 

 specimens closely resembling those of (/. equisetifolia, the whorls similarly 

 7-merous or the parts varying from 6 to 8, and often monoecious like that species. 

 Branches seldom if ever corky, the branchlets usually slender and quite glabrous. 

 Male spikes much more slender and interrupted, the short sheaths not 

 overlapping those next above. Fruit-cones more frequently tending to become 

 ovoid or oblong, truncate at both ends, the valves more prominent, glabrous or 

 nearly so, with usually a short broad thick but almost scale-Uke transverse dorsal 

 protuberance at the base rarely extending nearly to the apex of the valve. — Hook, 

 f. Fl. Tasm. i. 348, t. 96; C. leptodada, Miq. Kev. Gas. 41, t. 4, and in DC.

Wood dark-brown, prettily marked, coarse in grain, hard and tough ; used for buUook-yokes 

 and hurdles. In New South Wales used for mauls, shingles, staves, eta.— Baileij's Cat. Ql.

4. C. Cunninghamiana (after A. Cunningham), Blig. Eev. Cas. 56, t. 6, 

 and in DC. Prorf. xvi. ii. 885; Benth. Fl. Austr. vi. 198. A tree with slender 

 branches, closely resembling C. equisetifolia and C. suberosa in the aspect of the 

 specimens and number of parts of the whorls, and possibly a variety of one or the 

 other, but the fruiting-cones are much smaller, scarcely exceeding 4 lines in 

 diameter, globular, very regular, with prominent valves. Male spikes (in 

 Herb. R. Brown) slender like those of C. suberosa but more dense. 



Hab.: Woods of the London Exhibition, 1862, Hill, n. 9; Gilbert Eiver, Daintree ; an 

 ialand scrub tree. 



Wood dark-coloured, close grained and pretilly marked —Bailey's Gat, Ql. Woods, No. 404. 



5. C. inophloia (thready-bark), !<. v. M. and Bail, in Melb. Chemist and 

 Druggist, April, 1882. A small tree with a loose fibrous bark, disintegrating in 

 long, narrow, flat, particles. Branchlets very thin, slightly streaked, very 

 slightly downy. Whorls 7 to 9-merou3, the sheath-teeth acute. Male and 

 female inflorescence resembling that of C. suberosa having the same long slender 

 male spikes and rich purplish-red, female heads. Cones, 9 to 11 lines long, 7 to 

 8 lines broad, on peduncles of about 6 lines, almost globular, depressed at the top, 

 axis densely beset with straight pale-brown hairs ; bracts obliterated ; bracteolar 

 valves of the fruitlets rather small, semi-ovate, nearly blunt, shortly exserted, 

 enlarged by a very thick dorsal rather angular appendage, and of nearly as 

 much protrusion as that of the valves themselves; appendages and valves 

 very slightly downy ; nutlets (when young) pale, the terminating membrane 

 (then) about as long as the nucleus. 



"Hab.: Generally met with on sandy poor spots in the southern parts of the colony. 



Probably the species spoken of by Dr. Leichhardt under the n&me of C. villosu, and seen 

 by him on Kobinson's Creek at Expedition Range, Journ. to Port Essington, page 49. 



Wood very beautiful, of a reddisli colour but, with numerous dark-marks ; the grain close, 

 a very desirable wood for cabinetwork.—iiaiZf i/'s Cat. Ql. Woods, No. 405. 



6. C. distyla (styles two). Vent. Jard. Cels. t. 62 ; Benth. FL Austr. vi. 198. . 

 A dioecious shrub, usually only 2 or 8ft. high, with erect or spreading branches, 

 but in favourable situations attaining the "size of a small tree, the branches 

 glabrous or more or less pubescent. Whorls usually 7-merous, but the parts 

 varying from 6 to 8, the teeth short. Male spikes on deciduous branchlets of 1 to 

 Bin. or almost sessile on the persistent branches, 1 to \\ or rarely 2iu. long, more 

 or less mb'niliform, the sheaths not overlapping and the teeth not at all or 

 scarcely acuminate. Fruit-cones sessile or nearly so, oblong, from under f to 

 above lin. long, the broad very obtuse almost truncate valves slightly prominent
