摘要

A comparative anatomical study on the endozoochorous seeds of Monotropastrum humile (D. Don) H. Hara in comparison to the wind-dispersed seeds of Monotropa uniflora L. was conducted. The endozoochorous seeds were ovoid and had lignin-rich cell walls. These cell walls were six times thicker than those of wind-dispersed seeds. The ovoid seed was hypothesized to be an ancestral characteristic of the subfamily Monotropoideae (family Ericaceae). The evolution from the ancestral character state to the derived state (seeds having wing-like seed coats) was presumed to have happened four times independently in the subfamily.
