174), dum vera F. aspera (G. Forst.), fructibus iiuiltoties uiajovilnis 
eos F. Caricpe fere a?quantibus facillime divellenda est, ut e delinea- 
tionibus Forsteii diu iueditis a cl. Seemann demonstrabatur, conf. 
FI. Vitiensis 249. t. lxiv. et Lxv.). F. aspera apud no.s multo 
rarior est quam F. scabra.’ Compare also op. cit. vi. 196. Both 
Bentham and ^Mueller look upon F. aspera and F, scabra merely 
as varieties of the same species ; they only differ in opinion as to 
which name shall stand. Seemann gives figures of F. aspera and 
F. scabra from Fiji, which are cleardy distinct, though his illustra- 
tions may represent the most extreme forms, connected by inter- 
mediate ones. But this is somewhat uncertain, and it may also be 
that Seemann’s statement (op. cit. 250^, that F. aspera, as figured 
by him with larger fruits than scabra, extends to Australia, is 
incorrect. As far as I know, we have only the small-fruited form 
in Australia (identical with F. scabra of the Flora Vitiensis), and 
although it varies greatly in size and shape of the leaves, there 
does not appear to be any marked variation of the fruits. Bai'on 
Mueller in his latest work (Cens. p. 22, the last portion of the 
statement in Fragm. x. 114, notwithstanding), recognises only 
one species ( F. scabra) for Australia, and this seems scarcely to 
admit of doubt. F. aspera should therefore be dropped altogether 
so far as Australia is concerned. Add&ndv/m — The var. subglabra 
(Benth.) of F. aspera^, Forst. (B.Fl. VI. 175), should be included 
undei- F. stenocarpa, F.v.M. (loc. cit. \li). See alsoMuell. Cens. 
p. 22. It was made a distinct species (F. subglabra, F.v.M.) in 
Muell. Fragm. IX. 152.” 
Mr. Maiden also exhibited a portion of the stem of Alyxia 
huxijolia, E,.Br., for the discovery of su))posed medicinal properties 
and virtues in which, a patent has recently been taken out in this 
colony. 
Ilr. Katz exhibited an admiraVjly finished thermostat (apparatus 
for cultivating mici’o-organisms at a fixed temperature), a 
donation of the Hon. W. Macleay to the Biological Laboratory 
of this Society. This thermo.stat, designed by F. llueppe, has 
been imported from R. 1\I uencke, Berlin ; it is constructed of 
copper, and )u-ovided with a Reichert- Babes therino-regulator
