plausible, but of which the probability is diminished even in those with 
pentaphvllous calyx, and still more in Euthales, where the calyx is also 
tubular. But a stronger argument for the part usually denominated calyx 
being in these genera really such, may be derived from certain species of 
Goodenia, in which it will be admitted that both calyx and corolla are 
present, and where though both these envelopes adhere to the ovarium, 
they may be separately traced to its base ; the coloured corolla being 
plainly visible in the interstices of the foliaceous calyx. 
Goodenovi®, whose maximum exists in the principal parallel of New 
Holland, are nearly but not absolutely confined to Terra Australis ; the only 
known exceptions to this consist of the genus Cyphta , which is peculiar to 
Africa, and chiefly occurs at the Cape of Good Hope ; of some species of 
Sccevola which are found within the tropics ; and of Ooodenovia hi tor alls > 
which is common to the shores of Terra Australis and New Zealand, and ac- 
cording to Cavanilles is also a native of the opposite coastof South America* 
STYLlDEiE.* This order, consisting of Stylidium, Levenhookia, 
andForstera, I have formerly separated from Campanulace®, on account of 
its reduced number of stamina, and the remarkable and intimate cohesion 
of their filaments with the style, through the whole length of both organs. 
It differs also both from Campanulace® and Goodenoyi® in the imbricate 
{estivation of the corolla, and where its segments are unequal in the nature 
of the irregularity. In the relation which the parts of its flower have to 
the axis of inflorescence, and in the parallel septum of its capsule, it 
agrees with Goodenovi® and differs from Lobelia, which, however, in some 
other respects it more nearly resembles. 
Very different descriptions of the sexual organs in this tribe, and 
especially of the female, have been g’ivcn by several french botanists. 
According to Richard the lateral appendices of the label lum in Stylidium 
are the real stigmata, the style being consequently considered as cohering 
with the tube of the corolla, and the column as consisting of stamina only. 
This view of the structure demands particular notice, not only from the 
respect to which its author is himself intitled, but because it has also been 
adopted by Jussieu, F whose arguments in support of it, and against the
