1920] REHDER, NEW

The form supposed by Maximowicz to be the true D, scahra is not repre- 

 sented in Thunberg's herbarium. The figure on plate 24 in Thunberg's 

 Flora Japonica which is a reproduction of the original plate in Jus Disser- 

 tatio Nov. Gen. PL (1781) is not based on any single specimen, but appar- 

 ently on a combination of all three. The leaves and flowers are taken from 

 specimen ^, the fruit from specimen 7, while specimen a seems to have 

 been used only for the outline of the general habit of the branch.

the description of the filaments as " filaments - . . sub apice emar- 

 ginata trifida " (FL Jap, 10), as they are m D. crenatay while in D. Sie- 

 holdiana they are subulate or abruptly contracted below the apex, but 

 never trifid. Also other characters as " caulis ar])orescens orgyalis . . . 

 folia petiolata, ovata, acuminata, . . . peduncuH et pedicelli angu- 

 lati, tomentoso-scabra , . . petioli lineam longi " agree well w^ith 

 D. crenata^ but not with D. Sieboldiana which is usually a low shrub, 

 scarcely 1 m. tall, with, at least on the flowering branchlets, subsessile 

 leaves, oval or broadly elliptic-obovate in outline and abruptly short- 

 acuminate; the pedicles and peduncles are slender and usually pilose. 

 Also the plate, as stated above, agrees in its characters with D. crenata and 

 not with D. Sieboldiana; in representing the inflorescence as a simple raceme 

 the artist took apparently only the upper part of the inflorescence which 

 is described correctly by Thunberg as " pannicula composita." 



Though according to botanical usage one might be inclined to consider 

 the specimen designated as a as the type, I think there can be no doubt 

 that in this case the specimen & is to be considered the t\n>e of the species.
