Our plant differs fromn var. glabrescens RUPR ECTIT with bitter inedible berries. It is very difficult to distinguish this extremely polyniorphous plant into several varieties. The hairiness on branches and leaves, the shape of leaves, the length of bracts, the shape of berries, etc. are quite variable, and the varieties here distinguished are all connected by intermediate forms. In some occasions, one branch is entirely glabrous and the other densely pubescent even in the same individual. The key to discriminate the varieties in Japan is as follows :

On the Distribution and Construction of the Resin Canal in Rhus succedanea.1'

Morisige Harada.

With :1.3 Text-figures.

Received August 14, 1937.

I. Introduction. The resin canals in Rhus of Anacardiaceae hither-to have been studied by many botanists : ENGLER2'' 4) (1881, 1896) described the anatomy of the resin canals in the young branches of some species of Rhus, and then SOLEREDER5'(1899) described the distribution of the resin canals of Rhus viminalis, Rh. semialata and Rh. glauca in his work on the systematic anatomy of dicotyledons. MCNAIR°' (1918) investigated the distribution and construction of the resin canal in the stem of Rhus diversiloba. All these literatures treated namely the resin canals in Rhus which grow in foreign countries, but rather briefly, with the exception of MCNAm's description.
