164 Mr. DryANDER’s Obfervations 
the® Britith Mufeum (Sloan. MSS. 2915, p. 202); and the fpeci- 
men in the Linnean Herbarium has only male flowers: fo that the 
only knowledge I have of the female flowers is from Kampfer’s 
figure, in which the wings of the germen in feveral inftances have 
an acute angle, but in others are rounded; for which reafon I have 
avoided mentioning the fhape of the wings, in the difeconsid Ípe- 
.- eifica. 
Dr. Thunberg fuppofes this plant to be dioicous, but the figure 
of Kempfer has male and female flowers in the fame panicle. "This 
Íceming contradiction may be reconciled by an obfervation I lately 
made. I wanted to examine the female flowers of Begonia nitida; 
and looked for them on plants in full flower, both at Kew and in the 
Marchionefs of Rockingham's garden at Hillingdon; but could find 
nothing but male flowers, though it is very well known that the 
- B. nitida is monoicous. This circumftance is not peculiar to Begonias, © 
as I have feen a large cedar-tree for feveral years full of male catkins, 
without a fingle female one. Mr. L’ Heritier alfo informed me that the 
female flowers are very rarely to be met with in Ailanthus glandu- 
lofa; and I have not yet been able to find amy one in a large tree at 
Kew, which flowers very freely. 
This fpecies, and the following, macrophylla, have by far the 
largeft leaves of any in the genus; but this has twice as large 
flowers as macrophylla.
