Apospory in Pteris sulcata L. [PDF]
Botanical Gazette, 1919 1. The gametophyte generation of Pteris sulcata L. is ordinarily produced by the germination of a spore. 2. The embryo sporophyte is of apogamous origin. 3. The gametophyte generation of Pteris sulcata under certain conditions was produced aposporously. 4.

Biological Reviews, Volume 95, Issue 5, Page 1442-1466, October 2020., 2020 ABSTRACT Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above‐ and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of ...
