OBS. In the collection presented to the British Museum by Sir Thomas Mitchell, of the plants of his last expedition, there is a very perfect specimen, in flower, of Grevillea Sturtii.
The following observations respecting the Grevilleae of the same collection may not be without interest.
Grevillea Mitchellii, Hooker, in Mitch. Trop. Austr. p. 265, proves to be Gr. Chrysodendron, prodr. fl. Nov. Holl. p. 379, the specific name of which was not derived from the colour of the under surface of the leaves, which is, indeed, nearly white, but from the numerous orange-coloured racemes, rendering this tree conspicuous at a great distance.
Grevillea longistyla and G. juncea of the same narrative, both belong to that section of the genus which I have named Plagiopoda.
A single specimen, in most respects resembling Gr. longistyla, of which possibly it may be a variety, but which at least deserves notice, has all its leaves pinnatifid, instead of being undivided. It may be distinguished by the following character:--Grevillea (Plagiopoda) neglecta, foliis pinnatifidis subtus niveis; laciniis linearibus, stylis glabris.
A single specimen also exists of Grevillea (or Hakea) lorea, prodr. flor. Nov. Holl. p. 380, but without fructification.
24. GREVILLEA (CYCLOPTERA?) lineata, foliis indivisis lineari-ens formibus enerviis subter striis decem paucioribus elevatis uniformibus interstitia bis-terve latitudine superantibus, cicatrice insertionis latiore quam longa utrinque obtusa, racemis terminalibus alternis, pistillis semuncia brevioribus stigmate conico.
