Tbe aHinity of tliis species is witli C. acuan'a F. but difPers in the 
much larger size, the rigid divaricate brandies^ the length of the terminal 
(upper) internode and its distinctly tetragonal form, in the scale-leaves which 
ai'e long and niem]>ranon.s and terminate in tine sdaceous points, and ciliate 
on the margins; I he teeth of tlie male spike are much larger and acuminate, 
and the Hi>ikes shorter, more robust, and more coiitracted; the cones are 
larger (almost twice the size of those of C. acmiria), and the dorsal lamina 
is very much reduced, and ]>roduced into a stout triquetrous spine which only 
shortly exceeds the v'alvular ])ortion and iiiciirved at the a})ex. 
C. Prinsepiana C\ Andrews, in Jour. West. Aus. Xat. Hist. Soc. i. 43 (1904). 
The type specimen of this species, now in the possession of the State 
Herbarium, possesse.s no cones, the type consisting only of a small Iiranch 
with a young female inflorescence. A search for material in tlie herl)aria of the 
Royal Botanic Gardens, the Natural History Museum, South Kensington, and 
the Berlin Herbarimu proved futile in this respect, and we must assume that 
the type cones ai-e Jiot in existence. In 1936, Horace Brown brought me sjieci- 
mens of a ('asnarina from Wurarga, with several coiies, the bi'acteoles of which 
are tricnspidate, the two lateral points are side ])y sid(‘ very (dose to the 
extremity of lh{‘ vah e, witii a rounded thin valve afiex between tbein, and a third 
conical process from the dorsal surface. This api>eared to be an nndescriluul 
species, for wbicli I had ]M'oi>osed the name C. fricuspidata, hut still further 
material has been received from Mullewa, and a search for another Oasnarina 
which might prove to be tyjncal C. Prinsepiana has been un])T-oduciive. 
Andrews, in describing the bracteole of (’. Prinsepiana says ‘Ahalvos much 
exserted with ro?nided poinis, hack covered with long brown haii- below, 
glabrous in the fre(‘ part with two ])roniinent ridg(*s, o))tuse and extending 
beyond tbe apex of the valve; occasionally there is a third shorter protuher- 
anec between the other two, adnate lower down and ending in a short point.’’ 
This descriptioTi does not exactly api.dy to the Wurarga sixvdniens, but 
considering that these sharp ])oinls are so (‘asily damaged, and that the 
braiudilets of the two are imlistinguishable, it is ]ie)'haps best to ('onsider the 
Wurarga and Mullewa specimens recently collected as representing 
0. Prinsejriaim. The aHinity of the s[)ecies is with (\ tfeatiralvis, tlie plant 
differing in being a tree wifh tlie habit and ap])earance of C. (jJaaea, biit the 
cones of C. aenliralris, except that tlu^ bT'acteoh's Itear a conical dorsal appen- 
dage, and instead of a simple terminal conical point, there are two collateral 
conical protuberances — not ‘Vidges’^ extending beyond the valvular portion. 
In C, aentiralvis there may occasionally be found a division of the apex 
of the bracteole jmint into two ])oints, but in C. Prinsepiana the two points 
are quite distinct, and the obtuse and thin apex of the valvular portion is 
plainly visible Ijctween the two. 
C. bicuspidata Di(ds non lienih. 
The specimens deserilied as C. bicuspidata l)y Diels, collected near 
Southern Cross, the type of whicli I saw in the Berlin Herbarium, is 
C. acutivalvis F. Miiell. C. bicuspidata as far as is known, is restricted to 
South Australia and Tasmania.
