LEE, SANGTAE, CHUNGHEE LEE, YOUNGBAE SUH, SUNGHEE YEAU, AND NAM SOOK LEE.* Department of Biological Science, Sungkyunkwan University, Suwon 440-746 Korea. - Pollen morphology of the genus Adonis L. (Ranunculaceae) in Korea.
To elucidate the taxonomic identities of Korean Adonis, the pollen
morphology of 18 (14 Korean, 3 Japanese, and 1 Chinese) populations
were studied with light and scanning electron microscopes. The
populations were grouped as follows: Type I. A. amurensis (Korea:
Choongnyong Mt., Chunma Mt., Juksang Mt., and Jumbong Mt.): Foveolae
elongate, small, 27-40 per 49зн2, 2-3(5) aligned; echinae 0.9-1.24зн
length and 2-4/49зн2. Type II. A. ramosa (Japan: Tashiro): Foveolae
round, large and 20/49зн2, rarely aligned; echinae 0.8зн high and
4/49зн2. Type III. Foveolae round to elongate, small to large,
23-55/49зн2, sometimes aligned; echinae 0.31-0.74зн high and
6-17/49зн2. Subtype 1. A. multiflora (Korea: Kwanumsa and Yorimok;
Japan: Ryonuma): Echinae 6-8/49зн2, 0.35-0.59зн in length, 0.44-0.81зн
in width, L/W=0.73-0.80; foveolae 27-40/49зн2, similar sized. Subtype
2. A. pseudoamurensis (Korea: Jangbong Ir., Dukjuk Ir., Palgong Mt.,
Naesosa, Kwanchon, Euryoung, and Keryong Mt.; Japan:
Nishi-yoshino-mura; China: Kirin): Echinae 6-17/49зн2, 0.31-0.74зн in
length, 0.24-0.79зн in width, L/W=0.84-1.29; foveolae 23-55/49зн2,
size variable.
