The Austrii!; tsi of the northern hemisphere, and still more closely 
the genus Callitris of South Africa, and Fachylepis of North Africa, which differs chiefly in linving only tour scales 
to the cone. About fifteen Australian species are known, which are spread over all parts of that continent ; none 
are found elsewhere. — Evergret a Bhruba oi fen i i, some of which bear in the young state acicular leaves, but all of 
which, when fully developed, have minute leaves, whorled in threes, and adnate with the branch for the greater part 
of their length. Flowers monoecious ; the males consist of minute terminal catkins, of imbricating, peltate stamens, 
bearing on their stipes three or four small anthers, full of globose pollen. Female flower a small, six-scaled 
amentum, with many erect ovules at the base of each scale. Fruit, or ripe cone, woody, of six spreading sessile 
scales, the three alternate smaller. Seeds winged, compressed. Embryo with three cotyledons. (Named in honour 
of M. Frenel, an eminent French natural philosopher.)

(Gunn, 543, 1017.) 
Hab. Spring Bay, Oyster Bay, and other localities on the east coast, Backhouse; abundant on granite 
soil by the sea-coast, Flinders' Island, Gunn.— (Fl. Oct.) (Colonial name, " Oyster Bay Pine.") 
Disteib. South-eastern Australia, New South Wales, and Victoria. (Cultivated in England.) 
Backhouse describes this as a tree 50-70 feet high and 6-9 in girth, of a pyramidal shape, and giving a 
peculiar feature to the landscape; but Gunn gives it only 25 to 30 feet, and a diameter of 1, whilst at Flinders' 
Island it appears to be only 10-12 feet high, and forms dense thickets. Like many other Conifers, it probably 
varies extremely in stature.— Wood of little use, said to be obnoxious to bugs, from its resinous odour. Branches 
drooping (sometimes erect?), slender; the branchlets acutely three-angled, from the prominent keels of the adnate 
leaves. Male cones very small, about 1 line long. Ripe female cones sessile, about as large as a hazel-nut, of six 
unequal, woody, thick scales, the alternate ones half as large as the others, all produced at the back into a blunt 
gibbosity, that sometimes bears a sharp mucro. Seeds imbricated round a depressed, central, three-ridged axis.

Hab. Abundant upon gravelly banks of the South Esk River, near Launceston, etc.— (El. Nov.) 
(Colonial name, "Native Cypress.") 
Very nearly allied to F. rhomboidea, but with branches always erect, and larger, ovate cones, whose scales have 
not the dorsal gibbosity of that plant, and are generally less convex on the back, 'and sharper 'at the apex. The
