Iju Chen; Steven R. Manchester American Journal of Botany 2007. doi:10.3732/ajb.94.9.1534
Other claims from this paper (8)
- Observation Ampelocissus seeds differed from other Vitaceae genera in long parallel ventral infolds and an oval centrally placed chalazal scar.
- Method / resource Principal component analysis recognized four Ampelocissus seed morphotypes differentiated by four morphological characters.
- Association End-member Ampelocissus seed morphologies coincided with inflorescence morphology, geographic distribution, and ecology despite intergradation.
- Observation Seven fossil Ampelocissus morphospecies were recognized.
- Observation Ampelocissus parvisemina and A. auriforma resembled extant Central American species.
- Observation A. bravoi resembled one Old World extant species group.
- Observation A. parachandleri and three European fossil species resembled another Old World Ampelocissus group.
- Observation The Ampelocissus fossils occurred beyond the genus’s present geographic range.
