Folia ca.7-juga, jugo infimo a stipulisobsoletisvel deficientibus 

 paulo distante, ejus foliolis quam alia dimidio minoribus. Foliola 

 inter se distantia, coriacea, lanceolato-ovata vel oblongo-ovata, 

 saepe subfalcata, basi cuneato-rotundata vel cuneata, apice cus- 

 pidato-acuminata, margine grosse spinoso-dentata, dentibus in 

 latere inferiore 4-6, in superiore 3-5, supra nitida viridia vel atro- 

 viridia, in sicco nervis venisque conspicuis leviter elevatis, infra 

 flavido-viridia, nervis venisque subconspicuis ; foliolum terminale 

 aliis simile, basi cuneatum. Racemi ad 10 fasciculati, 10-20 cm. 

 longi, divergentes, simplices, laxiflori, rhachi subcrassa. 

 Bracteae ovatae vel lanceolato-ovatae, acuminatae, virides, 

 5-8 mm. longae, 2-4 mm. latae. Pedicelli graciles, sub anthesin 

 6-7 mm. longi, tandem ad 10 mm. elongati, nutantes. Sepala

 Nagasaki (Oldham ! No. 686), Tokyo (Terasaki ! v. 1906), etc. 



Obs— From the above description and the figures referred to, 

 it will easily be seen that the present species differs from M. 

 Bealei in many respects. Fedde's var. gracillima is nothing but 

 the typical M . japonica, while his M. japonica is a mixture of 

 M . japonica and M . Bealei. 



The writer has received from Mr. G. Reuthe, Keston, Kent, 

 specimens of Mahonia labelled as M. intermedia and M. Bealei. 

 As these specimens are represented by leaves alone it is difficult 

 to determine them with certainty, but the former appears to be 

 the typical M. japonica and the latter a large form of the same 

 species. If these specimens actually represent the so-called M.
