Alasemenia는 가장 오래된 세 날개 포배로, 날개가 바람 확산에 적응한 것을 보여준다.
The Famennian ovule Alasemenia tria represents the earliest known ovule with three broad, wing-like integumentary lobes that extend outwards, lacking a protective cupule. This suggests the integuments of the earliest ovules evolved functions in wind dispersal and probable photosynthetic nutrition.
