(botany) That has sporangia that were each formed from several epidermal cells; of, pertaining to, or characteristic of eusporangiate ferns.
2005, Philip J. Harris, 11: Diversity in plant cell walls, Robert J. Henry (editor), Plant Diversity and Evolution, page 220,Bailey and Pain (1971) examined the walls of a wide range of species of ferns (both leptosporangiate and eusporangiate) and divided the species into three groups depending on whether their walls contained low (0-3%), medium or high (>10%) concentrations of mannose.
2005, V. Raghavan, Developmental Biology of Fern Gametophytes, page 12,In the smaller of the two groups, known as the eusporangiate type, the sporangium originates from several initial cells.
2009, Singh, Pande, Jain, Text Book Of Botany Diversity Of Microbes And Cryptogams, page 468,Describe structure and development of leptosporangiate and eusporangiate sporangia. Draw diagrams.
