4 NOTE ON aUERCUS WALLICHIANA, LINDL. 



stowed upon his task from many quarters, that he is engaged in a pro- 

 fitless or a hopeless endeavour. How much remains to be done may 

 be gathered from this one fact, that the study of petals, styles, anthers, 

 and filaments in Rubi has only recently penetrated to this side the 

 Channel. 



NOTE ON qUERCUS WALLICHIANA, Lindl. 

 By H. F. Hance, Ph.D., etc. 



In arranging the Oaks of my herbarium some time ago, I found one 

 wliich had been collected in and sent me from Penang, but which I 

 was unable to refer to any of those described in the 'Prodromus.' Think- 

 ing it most likely, however, that the species would occur amongst the 

 collections of the late Dr. Wallich, T transmitted specimens to Kew ; 

 and Professor Oliver, who was so kind, at my request, as to compare 

 them with those in the herbarium under his care, informs me that they 

 are certainly referable to Qnerciis WaUichiana, Lindl. 



As this species, which has been erroneously referred by A. De Can- 

 doUe, from the comparison of a single leaf only (which, after all, can 

 scarcely have belonged to the Penang tree), to the very distinct Q. 

 lamellosa, Sm., has never, that I am aware, been described, I have 

 thought it as well to draw up the subjoined diagnosis from the mate- 

 rials at my disposal.
