on Roxburgh’s R. Bucki-Amelam ; R. chinensis Mill. he retains as a 
distinct species. Prof. Engler (in DC. Mon. Phan. iy. 380) retains 
these varieties, and adds a short diagnosis of each—‘ petiolis inter 
juga late alatis,” for Osbeckii — which he places Rh. javanica L.) 
and ‘ petiolis inter juga nest issime alatis vel exalatis’’ for Row- 
burghii, under which he puts R. chinensis Mill. e specimen of 
Rhus representing javanica in Linn. Herb. has exalate petioles, 
while in those of Plukenet and Miller the petioles are distinctly 
(in Miller’s very conspicuously) winged, and they are so described in 
d. ct. 
I am inclined to think that the original name of Linneus 
should ae retained for the species; his “diag gnosis, though brief,

on any ground this should be set aside, ther no reason against 
the idertion R. chinensis Mill., which Geccderably antedates
