NOTES ON RHUS. 
By James Brirren, F.L.S. 
g. ‘: 
The nS is altered to “China” in Sp. Pl. ed. 2, no doubt 
correctly, as Osbeck oo Ostind, Resa, p. 282 (1787) ). cae in 
de rubro 
his diary under Sept , 1751, as ** Rhus javanica, germin 
Chin. Taj-scha.” ahs oe Linnean Herbarium R. javanica is repre- 
sented by two sheets; the first, bearing the name and number (2) 
in cpa s’s hand, is Brucea sumatrana; the second, not named 
ut similarly regi tg is practically Hdohual with R. Bucki- 
Anil Roxb. (R. Amela D. Don), which is generally considered a 
form of f. semialata. 
‘In his diary (/.c.) Osbeck has also ‘‘ Rhus chinensis blommade 
wid graswarna och tallades af Chineserma Monchi’’; this is also 
identified by Bretschneider with R. semialata. The name was 
adopted ed emg by coincidence) by Philip Miller onion Diet. 
ed. viii. no. 7 8)), who cites as a synonym “ Rhus arum 
lactescens, cot erated alaté. Pluk. Am. 183.” Plukenet’s 
specimen is in his herbarium Herb. Sloane xciv. f. 67) and two 
sheets from Miller's herbarium are in Herb. Banks: all these repre- 
sent the form of R. semialata having conspicuously winged petioles. 
The only author who seems to have been aware tha neus 
sag two plants in view is, so far as I know, R. A. Salisbury, who 
n his Prodromus (p. 171) cites R. javanica L. as @ synonym of his 
Ailenth gracilis (= Brucea sumatrana). We have a specimen of 
. gracilis pon Salisbury’s eee 1785, written up: ‘‘ Rhus 
jovani of Linné: an vere hujus generis ?”’
