Few patients noted the expulsion of strobili while defecating
The cylindrical strobili of Asterophyllites grandis possess bracts similar to the vegetative leaves, and sporangiophores situated at about middle distance between verticils.
Strobili appear before the new leaves; male strobili many and sessile in whorled, short, crowded clusters near ends of twigs, mostly in lower part of the crown; mature cones usually reflexed, symmetrical; cone scales reflexed or wide spreading, thin, flat, dark chocolate-brown on inner surfaces; seeds narrowly ovoid, about twice as long as broad, pointed at both ends, three angled, averaging less than 6mm long, 3mm wide, black, mottled grey or light brown.
But the extensive evidence for parasitic insects in extinct seed plants making a switch to become pollinators has also to account for a switch from unisporangiate to bisporangiate strobili. Any potential angiosperm ancestors require modification in many organs that work together in seed production associated with the origin of hermaphroditism, i.e., the development of bisporangiate strobili.
Pollen strobili two to six per stem apex, to 14 x 3 cm, yellow-beige tomentose, peduncles to 6.5-8.0 x 1-1.4 cm, yellow-beige tomentose with green undertones; microsporophylls arranged in 14-16 orthostichies of 16-25 fertile sporophylls each, obtrullate, 10-11 x 89 mm at pollen shedding, bullae encompassing 1/4 to 1/3 of total length of sporophyll, beige-yellow tomentose, face hexagonal, 5-5.2 x 4.2-4.5 mm, distal facet shallowly indented, microsporangia 37-43, 1.2 x 1 mm, limited to the abaxial surface and aggregated into a single group, lower half of pedicels without microsporangia.
Ontogeny of strobili, sporangia development and sporogenesis in Equisetum giganteum (Equisetaceae) from the Colombian Andes.
The influence of florivores perhaps is not surprising, given the close association between insects and flowering plants likely developed as an initially antagonistic relationship, due to the increased attractiveness of flowers as food items of early angiosperm flowers relative to gymnosperm strobili (Frame, 2003).
In a mast year, 70% of all plants in a population may produce strobili, while as few as 2% of plants may produce seed in non-mast years (Ballardie and Whelan 1986:100).
