34 GENEIIAL REMARKS OX THE 



both these envelopes adhere to tlie ovarium, they may be 

 separately traced to its base ; the coloured corolla being 

 plainly visible in the interstices of the foliaceous calyx. 



Goodenovise, whose maximum exists in the principal 

 parallel of New Holland, are nearly but not absolutely 

 coniined to Terra Australis ; the only known exceptions to 

 this consist of the genus CypUia, which is peculiar to Africa, 

 and chiefly occurs at the Cape of Good Hope ; of some 

 species of Sccevola which are found Avirhin the tropics ; and 

 of Goodenovia litf oralis, whicli is common to the shores of 

 Terra Australis and New Zealand, and according to Cava- 

 nilles is also a native of the opposite coast of South America. 



STYLIDE-zE.^ This order, consisting of Stylidium, 

 Levenhookia, and Forstera, I have formerly separated from 

 Campanulacese, 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, 

 [t differs also both from Campanulacese and Goodenovise in 

 the imbricate aestivation of the corolla, and where its seg- 

 ments are unequal in the nature of the irregularity. In the 

 relation which the parts of its flower have to the axis of in- 

 florescence, and in the parallel septum of its capsule, it 

 agrees with Goodenovise and differs from Lobelia, which, 

 how^ever, 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 given by seve- 

 ral French botanists. According to Richard the lateral ap- 

 pendices of the labellum 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 par- 

 ticular notice, not only from the respect to wdiich its author 

 is himself entitled, but because it has also been adopted by 

 Jussieu,^ w^hose arguments in support of it, and against the 

 562] common opinion, may be reduced to three. 1st. Were 

 the common opinion admitted, the difficulty of conceiving 

 so wide a difference in what he terms insertion of stamina
