COLLECTED BY CAPTAIN STURT. 335 



The following observations respecting the Grevilleas of 

 the same collection may not be without interest, 



Grevillea Mitchellii, Hooker, in Mitch. Trop. Austr. p. w 

 265, proves to be Gr. Chrysodendrum, jorcK^r. 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 resembhng 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 fol- 

 lowing character : — Grevillea {Plagiopoda) neglecta, foliis 

 pinnatifidis subtus niveis ; laciniis hnearibus, sty lis glabris. 



A single specimen also exists of Grevillea (or Hakea) 

 lorea, prodr. fior. Nov. Holl. p. 380, but without fructifi- 

 cation. 



24. Grevillea (Cycloptera ?) lineata, foliis indivisis 

 lineari-ensiformibus enerviis subter striis decern paucioribus 

 elevatis uniformibus interstitia bis-terve latitudine supe- 

 rantibus, cicatrice insertionis latiore quam longa utrinque 

 obtusa, racemis terminalibus alternis, pistillis semuncia 

 brevioribus stigmate conico.

 in the creeks about lat. 29° 30' S." D. Sturt. 



Obs, It is difiicult 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 diff'erence, contrasted with which 

 the leaves of G. striata have always more than 10 striae, 

 which are hardly twice the breadth of the pubescent in- [88 

 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 supplement to 

 the Prodr. Plor» Novse HoUandise, I have employed in a
