As regards the fruit at least, there are two quite well-marked varieties, in one of
which the fruit ripens nearly a month earlier, is reddish, especially within, and
mealy, rendering it very pleasant. In the other later-maturing kind, the frnit, be-
sides being larger, is not reddened or mealy, and is far less palatable. Last half of
May ; fruit, October and November.
