| Abstract: | In the course of our palynological study on the Chinese Lilium, pollen
tetrads are found in two taxa of the genus: L. sempervivoideum and L. amoenum. The
latter is distributed in NW. and S. Yunnan Province. It was established by Wilson,
but reduced later by himself to a synonym of L. sempervivoideum which occurs from S.
Sichuan to C. Yunnan. However, it is regarded as a species distinct from the former by
many authors, such as Sealy (1949), Woodcock and Stearn (1950) and S. Y. Liang
(1980).
Their pollen tetrads are similar in aperture appearance and sexine patterns, but
different in the shape, size and arrangement of sculptural elements, as shown by LM
and SEM examination. Their leaf shape and flower colour are different, though there
are some transitions between them. Based on the facts mentioned above, it is reason-
able to regard the two taxa as two subspecies in L. sempervivoideum. |
