The above two species, although more decidedly dicecious than many 
others, cannot be generically distinguished. from Z/ex. In almost all 
the Eastern species at least there appears to be a tendency to sexual 
separation, or at any rate to a predominanct of each of the sexes in dif- 
ferent individuals. The male individuals have usually the flowers more 
numerous in each fascicle, the pedicels more slender, the filaments 
longer, and the ovary often quite rudimentary ; the females (which are 
always to a certain degree apparently hermaphrodite) have the flowers 
few in each axil or solitary, the pedicels usually thickened under the 
flower, the stamens always present, but with short filaments and perhaps 
sterile anthers, and a perfect ovary. The number of parts of the flower, 
ete., although constantly quaternary in some species, varies in others 
in fours, fives, or sixes, and is occasionally even reduced to threes.

Subarboreous, in the Happy Valley woods. Flowers in April, nu- 
merous, light lilae, sometimes white. There is also a smaller variety, 
with much smaller leaves, minutely denticulate, the teeth mucronate ; 
it forms a shrub on bare hills, with a scarlet berry.

Woods in the Happy Valley, near the Waterfall, flowering early in 
spring. It is closely allied to F. floribunda, Wall., from Nepal, to 
F. urophylla, Wall., from Silhet, and to F. longicuspis, Sieb. et Zucc., 
from Japan, and it is not improbable that the whole may be mere 
varieties of one species.
