 Rh obovata, and possibly cuneata, one of the anthers is abortive, a circumstance which approximates the genus to Conospermum and Synaphea; but in A. sericea, terminalis, and perhaps the other filiform-leaved species, the anthers are all fertile.

It is not a little remarkable that in so diversified an order as this, scarcely any tendency to vary from the small number of types of structure recognised thirty years since by Dr. Brown should be discoverable; there is nothing whatsoever among the numerous undescribed species from Swan River which requires the establishment of a new genus, with the solitary exception of Manglesia. That genus was named by Endlicher in compliment to Captain James Mangles, R.N. and Robert Mangles, Esq. his brother, to whose exertions the country owes the greater part of the plants as yet introduced from this colony into our gardens; and it appears to be well distinguished from Grevillea by the style being thickened in a very remarkable manner a little below the stigma, while the stipes of the ovary is unusually long. Three species only are yet known; all from Swan River, namely M. tridentifera, vestita, and glabrata, 183 all small shrubs with three lobed or trident-shaped leaves, and numerous clusters of small flowers seated on filiform stalks; but with regard to the two Grevilleas which Brown calls Conogyne, and which Endlicher is inclined to refer to Manglesia, it does not appear to me certain that either of them belongs to it, and G. triternata certainly does not.



There are no other orders of Exogens sufficiently remarkable, as to the proportion they bear to the rest of the Flora, to require especial notice; but there are several genera belonging to different orders, concerning which it is desirable to make a few observations.

Of the beautiful genus there are many species, all apparently peculiar to the colony; and, what is curious, belonging to the pentamerous division of the genus.
