SyilOliyillS.— C. quadrivalvis, Labill.; C. macrocarpa, A. Cunn.; C. cristata, 
Miq.; C. Gunnii, Hook, f.; C. truncata, Willd., and C. quadridentata, Desf. (teste 
Miquel) ; C. excelsa, Salisb. (teste Steudel). 
C. quadrivalvis, Labill., was described in 1S06. It is necessary to note this date, 
because C. slricta, Ait., lias been suppressed in its favour by some botanists. It is 
not a sufficient reason to suppress C. stricta because of its inappropriateness. 
C. macrocarpa, A. Cunn.— 
Casuarina macrocarpa, new sp. Ramellis flaccidis longissimis minutissime sulcatis ciliatis strobilis 
inermibus ciliatis. A tree about 30 ft. high. Dioecious. W. of Bathurst. 
The above is an unpublished extract from Allan Cunningham’s Journal, 
under date 4th May, 1817. 
Miquel defines his variety macrocarpa (a name be obviously borrowed from 
Cunningham) in these words* :— 
Strobileis femineis robustioribus globoso-ellipsoideis, ramulis contra haud crassioribus.—Notas vere 
differentiales haud inveni (ad Lachlean (Lachlan) flumen, A. Cunningh.). 
Miquel figures it at B, tab. x, op. cit. 
C. cristata, Miq. (op. cit. p. 336 and table x, A). I am doubtful about 
C. cristata, the description being so vague in many respects that it applies as well 
to a small-fruited form of C. stricta as to C. lepidophloia (the Belah). 
Bentham gives C. cristata, Miq., as synonymous with C. stricta, and I would 
hardly dare to say he is wrong. 
Bentham remarks :— 
The Lachlan River specimens distinguished by Miquel as two varieties under the names of 
macrocarpa and cristata were probably all gathered from one tree ; the cones do not appear to me to be 
larger than are many of the Tasmanian specimens. (B.F1. vi, 195.) 
F. A. G. Miquel, in his monograph of the Casuarinese in He Candolle’s 
Prodromus, xvi (2) 332 (1868), proposes three varieties of C. quadrivalvis (he keeps 
quadrivalvis, Labill., and stricta. Ait., distinct), viz. :— 
1. macrocarpa. 
2 . cristata. 
3. spectabilis. 
Miquel founded a variety, spectabitis, of this species on a Tasmanian plant, 
and following are Hooker’s observations :— 
Var. spectabilis, Miq., humilis, ramulis robustis, sulcis latiusculis tomentellis, amentis masculis 
crassioribus. C. Gunnii, Nob. MSS. ; Miq. in Ned. Kruidk. Archief iv, 100 (Gunn, 1247). 
forming dense small thickets near Georgetown and on Flinders’ Island, Gunn .Gunn is 
doubtful whether the var. spectabilis is not a distinct species ; Miquel first placed it under quadrivalvis, 
but has since published it as different; I find no character but its robust habit to distinguish it, and 
Victoria specimens are quite intermediate in this respect. (Hooker’s Flora of Tasmania, Vol. i, p. 348, 
under C. quadrivalvis.)
