Botany

However, sporangia are not always available for fossil ferns; and when present, determining sporangial type is often difficult.
Example sentencesExamples
- The genera are characterized by the sporangiophore and sporangial features and their relationship to and appearance of the rhizoid structures.
- Figure 2 illustrates asexual sporangial structures seen with several of the common Mucoraceae.
- The cone axis is not visible, but the sporangial clusters appear to be arranged spirally.
- However, closer evaluation of sporangial shape shows clearly that there is more variation within the genus than was previously suspected.

Origin

Early 19th century: modern Latin, from Greek spora 'spore' + angeion 'vessel'.
