microsporophyll: Leaflike structure giving rise to one or more microsporangia.
It is interpreted as a male cone composed of peltate microsporophylls, the elongate sporangia being attached to the heel of the microsporophyll and parallel to the stalk.
In other forms the terminal telomes may have undergone the same processes as in the carpel, and a broad expanded microsporophyll resulted, as in the Magnoliaceae (Can, right, 1952).
Microsporophyll lamina soft, not dorsiventrally thickened,
Isoetes is heterosporous, with each leaf a potential microsporophyll or megasporophyll.
The compound pollen strobili of Austrotaxus have a unique arrangement whereby the stalks of the microsporophylls are vestigial, the microsporangia of each microsporophyll are fused to each other and partially adnate to the microsporophyll itself (Saxton, 1934; Wilde, 1975).
