Abstract

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.

Key words: Lilium, tetrad, microstructure, ultrstructure, L. sempervivoideum Lévl.
