According to Fritz
Muller, a species of this genus in St. Catharina, in Southern Brazil, is
homostyled. (4/10. 'Botanische Zeitung' 1868 page 112.)
Lagerstroemia Indica.
This plant, a member of the Lythraceae, may perhaps be heterostyled, or may
formerly have been so. It is remarkable from the extreme variability of its
stamens. On a plant, growing in my hothouse, the flowers included from nineteen
to twenty-nine short stamens with yellow pollen, which correspond in position
with the shortest stamens of Lythrum; and from one to five (the latter number
being the commonest) very long stamens, with thick flesh-coloured filaments and
green pollen, corresponding in position with the longest stamens of Lythrum. In
one flower, two of the long stamens produced green, while a third produced
yellow pollen, although the filaments of all three were thick and flesh-
coloured. In an anther of another flower, one cell contained green and the other
yellow pollen. The green and yellow pollen-grains from the stamens of different
length are of the same size. The pistil is a little bowed upwards, with the
stigma seated between the anthers of the short and long stamens, so that this
plant was mid-styled. Eight flowers were fertilised with green pollen, and six
with yellow pollen, but not one set fruit. This latter fact by no means proves
that the plant is heterostyled, as it may belong to the class of self-sterile
species.
