sequently assumes a very diiFerent appeamnce, owing to a 

 change in the form of the indusium or membranous ap- 

 pendage which shrouds it. 



The present genus consists of stemiess herbaceous plants 

 with a radical subspatulate foliage, yellow flowers and an 

 indusium of the largest dimensions. 



We shall introduce in this place some instructive re- 

 marks by Mr. Brown.

" I have elsewhere observed, that in two genera of Good 

 ** enovicBy namely, Euthales and VelLeia, the base of the 

 *' corolla coheres with the germen while the calyx remains 

 entirely distinct. This structure I had stated as being 

 peculiar to these genera, and as in' some degree invali- 

 dating one of Jussieu's arguments for considering the floral 

 envelope of Monocotyledones as calyx rather than corolla. 

 The fact, however, seems not to be admitted by Richard, 

 who in] a dissertation already quoted describes what has 

 " hitherto been called calyx in Velleia as bractese : a view 

 " of the structure which in those species of that genus having 

 triphyllous calyx, may appear plausible, but of which the 

 probability is diminished even in those with pentaphyllous 

 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 

 " germen, they may be separately traced to its base; the 

 ** coloured corolla being plainly visible in the interstices of 

 " the foliaceous calyx." 



" Goodentmicey 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 Cyphia, which is peculiar to 



" Africa, and chiefly occurs at the Cape of Good Hope; of 

 some species of Sc^vola which are found within the tro- 

 pics; and of GooDENOViA littoralis, which is common to 

 the shores of Terra Australis and New Zealand, and 

 according to Cavanilles is also a native of the opposite 



" coast of South America.** Brown gen. rem. in append, to
