Abstract

Pollen morphological studies using light and scanning electron microscopy were conducted to determined the sub-sectional boundary and species relationship of 12 species of subsect. Meleuphorbia and related taxa. Based on the sculpturing patterns of pollen grains and UPGMA tree from numerical analyses using 8 quantitative pollen characters 12 species were divided into two types: type I, having microperforate pollen grains in E. epicyparissias, E. inermis, E. pillansii, E. obesa, E. bubalina, E. meloformis, E. nesemanii, and E. jansenvillensis, and type II, having fossulate sculpturing pattern in E. longituberculosa, E. monteiri, E. caput-medusae and E. grantii. The resulting pollen data suggest that the subsect. Meleuphorbia should not be a natural group, but closely related to the species from subsect. Anthacantha and sect. Treisia and sect. Medusea. Thus, the pollen morphological data recommended to combine above taxa as a single taxonomic group.

대극과 대극속 Meleuphorbia아절의 한계와 근연 분류군과의 유연관계를 규명하기 위해 Meleuphorbia아절에 속한 3종과 근연 분류군에 속하는 9종을 포함하여 총 12종의 화분을 광학 및 주사전자현미경으로 관찰하였으며, 8개의 정량 화분 형질을 이용한 수리분석을 바탕으로 2개의 유형으로 구분하였다: 화분의 표면 무늬가 미세유공상인 Type I (E. epicyparissias, E. inermis, E. pillansii, E. obesa, E. bubalina, E. meloformis, E. nesemanii, E. jansenvillensis), 화분의 표면 무늬가 추문상인 Type II (E. longituberculosa, E. monteiri, E. caput-medusae, E. grantii). 화분 형태학적으로 Meleuphorbia아절은 자연분류군이 아닐 가능성이 크며, Meleuphorbia아절에 속하는 종들은 Anthacantha아절, Treisia절, Medusea절에 속한 종들과 유연관계가 깊은 것으로 나타나, 이들을 함께 하나의 분류군으로 처리하는 것이 바람직하다.
