COLLECTED BY CAPTAIN STURT. 335
The following observations respecting the Grcvillca3 of the same collection may not be without interest.
Grevillea Mitchellii, Hooker, in Mitch. Trop. Aasfr. p. >- 2C5, proves to be G\\Q\\vy^oi\G\u\v\u\\, jrrodr. Jl. Nov. Jlo/l. 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 Avhich 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 pinnatiiid, instead of being undivided. It may be distinguished by the fol- lowing character : — Grevillea [Flagiopoda) negleda, foliis pinnatifidis subtus niveis ; laciniis linearibus, stylis glabris.
A single specimen also exists of Grevillea (or Ilakea) lorea, j^^'odr. for. Nov. Holl. p. 380, but without fructifi- cation.
24. Grevillea (Cycloptera?) lineata, foliis indivisis lineari-ensiformibus enerviis subter striis decem j)aucioribus elevatis uniformibus interstitia bis-terve latitudine supe- rantibus, cicatrice insertionis latiore quam longa utrinque obtusa, racemis terminalibus alternis, pistillis senumcia brevioribus stigmate conico.
Log. " It takes the place of the gum-tree (Eucalvptus) in the creeks about lat. 29° 30' S." D. Sturt.
Obs. It is difficult to distinguish this species, which, according to Captain Sturt, forms a tree about 20 feet in height, from Grevillea striata. I have endeavoured to do so in the above specific difference, contrasted with which the leaves of G. striata have always more than 10 striue, which are hardly twice the breadth of the pubescent in- [^s terstices, and the cicatrices of whose leaves are longer than broad, and more or less acute, both above and below. This is a source of character which in the su])plement to the Prodr. Floree Novse HoUandicc, I have employed in a
