APPENDIX. [ Botany of Terra Australis. 
common opinion, may be reduced to three. 1st. Were the common opi- 
nion admitted, the difficulty of conceiving so wide a difference in what he 
terms insertion of Stamina, in two orders so nearly related as Campanula- 
ceae and Stylideae obviously are : 2dly. The alleged non-existence of the 
Stigma, which preceding authors had described as terminating the column : 
and lastly the manifest existence of another part, which, both from its ap- 
pearance and supposed origin is considered as capable of performing the 
function of that organ. 
In opposition to these arguments it may be observed, that the real 
origin of the Stamina is in both orders the same, the apparent difference 
arising simply from their accretion to the female organ in Stylideae, a ten- 
dency to which may be said to exist in Lobelia. The inability to detect 
the Stigma terminating the column in Stylidium must have arisen from the 
imperfection of the specimens examined, for in the recent state, in which 
this organ is even more obvious than in Goodenoviae at the time of bursting 
of the antherae, it could not have escaped so accurate an observer as Richard ; 
and were it even less manifest in Stylidium, its existence would be suffici- 
ently confirmed from the strict analogy of that genus with Levenhookia, 
whose stigma, also terminating the column, consists of two long capillary 
laciniae, which are in no stage concealed by the antherae. 
With respect to the part considered as Stigma by Richard, I have 
formerly observed that it is obsolete in some species of Stylidium and 
entirely wanting in others,* and there is certainly no trace of any thing 
analogous to it in Forstera. 
The greater part of the Australian Stylidece exist at the western ex- 
tremity of the principal parallel, several species are found at the eastern 
extremity of the same parallel, and a few others occur both within the 
tropic and in Van Diemen’s Island. Beyond Terra Australis very few 
plants of this order have been observed ; two species of Stylidium, very 
similar to certain intratropical species of New Holland, were found in 
Ceylon and Malacca by Koenig ; and of the only two known species of 
Forstera, one is a natve of New Zealand, the other of Terra del Fucgo, 
and the opposite coast of Patagonia.
