The male flowers of the typical form of his species have broadly orbicular-ovate 

 very short-pointed or obtuse bracts which are distinctly dark rcd-l)rown at the 

 apex and clear yellowish below. The male flowers of Faurie's No. 1532 arc hardly 

 different, but the main part of their bracts is brownish without such a strong con- 

 trast in color as in the flowers of the Japanese specimens before me. Winkler (1914) 

 in describing the male flowers from Faurie's No. 1532 mentions a white cross line 

 beneath the dark apex which I did not find in the specimen in the herbarium of 

 the Arnold Arboretum. 1 am not quite sure whether No. 1532 does belong to 

 C. Fauriei with finely puberulous fruits or to the api)arently t\i)ical C. laxijlora 

 represented by the other specimens from Korea. The island of Quelpaert is rich 

 in distinct forms. 



As far as 1 know the typical C. laxijlora Siebold & Zuccarini does not occur in 

 Mandshuria or China. There are the following two Cliinese varieties: 



Carpinus laxiflora, var. macrostachya Burkill. See p. 425. 



Carpinus laxiflora, var. Davidii Franchet. See p. 426.
