THE FLORA HONGKONBElSrSIS. 31 



P. flacddwn, Eoxb., P. Bonii, Meissn., P. serrulatmi, Lag., 

 P. jucundzm, Meissn., all found on the adjacent mainland, in 

 ditches and pools, will most likely prove to lie natives of Hong- 

 kong. 



*Su2eda australis, Moguin. 



Mr. Bentham now (M. Austr. v. 206) concurs with J. D. Hooker 

 in regarding this as not specifically distinguishable from S. mari- 

 tima, Du:moTt., a plant widely spread over the sea-shores of Europe 

 and America. 



*Ciimamomuin Biirmarmi, Blwme; teste Meissn, in DC. Prod. xv. 16. 

 (=C, dulce, Neesi Benth. Fl. Hongk. 290.) 

 I adopt Blume's name, as the oldest, because Meissner iden- 

 tified with his plant specimens named O. ekdce in Nees von 

 Esenbeck's own handwriting. Miquel, however (Ann. Mus. Bot; 

 Lugd.-Bat. ii. 195), considers Nees's O. dulce the same as Meiss- 

 ner's O. Sieholdi. It is probable that the species have been un- 

 justifiably multiplied. I do not think this tree, which supplies, 

 unless I err, in part, at least, the Oassia-bark of the Canton 

 market, is indigenous to Hongkong. 



*Ciiinainoinuiii Neesieuiuin, ^. petiolare, Meissn. in DC. Prod. xv. 

 26. ( = Camphora Parthenoxylon, Benth. PI. Hongh, 290.) 

 Meissner denies that this is identical with Nees's GmvpJiora 

 iilon. 



•Tetranthera laimfolia, Jacg. ; Wmssn. in DC. Prod. xv. 178. (=T 

 citrifolia, Benth. Fl. Hongk. 293.) 

 Bentham gives Jussieu as the authority for the name adopted by 

 him, but without any specific reference : it is very inappropriate, 

 and has been abandoned by myself in the 'Mora Australiensis '. 

 for the present one. 



*Litsaea pulchella, Meissn. in DC. Prod. xv. 224. (=Litssea ceylanica, 

 Benth. Fl. Hongk. 294, but not of Nees.) 



Not known out of the island. Meissner considers this more 

 nearly allied to L. acitmlceta, Blume, and L. glaicca, Siebold, than 

 to L. oiijlcmiea, Nees. 



The natural order Euphorbiaceae has been thoroughly revised, 

 in the fifteenth V0lume of PeCandolle's ' Prodromus,' by Herr 

 Johann Miiller, of Aargau, who, discarding the old arrangement, 

 divides the family into ten tribes and a very great number of 

 subtribes, and has made most extensive changes in the circum- 

 scription of the genera, difiering widely from M. BaiUon in his
