348 FLORA. OF TASMANIA. \Casuarinece . 
bus 9-1 2-striatis, striis verruculosis sulcis puberulis, vaginarum dentibus lanceolatis ciliolatis erectis, amentis 
masculis 10-30-articulatis, vaginis campanulatis, strobilis breviter pedunculatis breviter elliptico-oblongis 
17-18-stichis, bracteolis porrectis acutis pungentibus. — Miq. Bevis. Crit. Cas. 71. t. ix. C. (Gunn, 736.) 
Var. spectabilis (Miq. 1. c. 73. t. x. C) ; humilis, ramulis c sculis tomentellis, amentis 
masculis crassioribus. C. Gunnii, Nob. MS8. ; Miq. in Ned. Kruidk. Archie/, iv. 100. {Gunn, 1247.) 
Hab. Abundant in good light soil in stony places throughout the Island, except towards the north- 
west. Colonial name, "She-Oak." — (Fl. Oct.) (v. v.) Var. spectabilis forming dense small thickets near 
Georgetown and on Flinders' Island, Gunn. 
Distbib. South-eastern Australia, from subtropical New South Wales to Victoria. 
A very common small tree, 20 feet high, with pendulous, slender branches, that have an acid taste ; its wood 
is used for firewood, and will burn even when green. It differs from the other Tasmanian species in its more ro- 
bust male inflorescence, more numerous striae to the branchlets, and corresponding teeth of the sheath and flowers 
in each whorl, which vary from nine to twelve, and especially in the ripe cone, which is an inch long, shortly 
elliptic-oblong, with projecting, acuminate, ovate, pungent tips to the bracts which enclose the cavities containing 
the caryopses ; these bracts are close-set, and leave no flattened surface between their backs, which are smooth, 
pale-brown, and keeled. Gunn is doubtful whether the var. spectabilis is not a distinct species; Miquel first 
placed it under quadrivahis, but has since published it as different ; I find no character but its robust habit to dis- 
tinguish it, and Victoria specimens are quite intermediate in this respect. 
2. Casuarina distyla (Vent. Plant. Nouv. 62) ; humilis, ramulis strictis 6-9-angulatis, angulis ob- 
tusis, sulcis medio glabris puberulisve, vaginarum dentibus lanceolatis ciliolatis, amentis masculis 10-20- 
articulatis, strobilis subsessilibus oblongo-cylindraceis sub-14-stichis, bracteis breviter ovatis acutis irregu- 
lariter subtuberculatis. 
Var. a; internodiis 6-7-sulcatis.— C. distyla, Miq. Bevis. Cas. 57. t. vii. A, C. {Gunn, 735.) 
Var. £. rigida; internodiis longioribus 7-9-sulcatis.— C. rigida, Miq. I.e. L vii. P. {Gunn, 735 et 
735?) 
Hab. Common throughout the Colony, ascending to 4000 feet.— (Fl. Oct.) {v. v.) 
Distrib. New South Wales and Victoria. 
Miquel, in his valuable revision of Casuarina, has separated Gunn's 735 into two species, as C. distyla and C. 
rigida, differing in C. rigida having usually seven or eight instead of six or seven angles on flic branchlets. It is a 
very common small ! ask, I up eiallv abundant near the sea, where it forms low thickets 2-5 feet high, and is distin- 
guished by its straight erect branchlets from C. quadrivahis, also by its more oblong cone, with less prominent 
bracts, which are less acuminate and pungent, and more or less tubercled or uneven on the back.

Hab. Common on stony hills. — (Fl. Oct.) {v. v.) 
Distrib. New South Wales and Victoria. 
Tl la i 
t species, growing 15 feet high, and is probably the normal state of the species of which C. i 
tyla is a variety. It is well known as the " He-Oak," in contradistinction to the C. quadrivahis, or " She-Oak," 
a name, I believe, adapted from the North American " Sheack -." though more nearly allied botanically to the Nor- 
thern Oaks than any Tasmanian genus except Fagus, they have nothing to do with that genus in habit or appear- 
ance, nor with the Canadian « Sheack." Gunn savs of this that he does nnt Wv W it. «.
