strobili's Usage Examples:

In Ulodendron the large circular, distichously arranged prints were supposed to have been formed by the pressure of the bases of sessile cones, though this interpretation of the scars is open to doubt, and it is now more probable that they bore deciduous vegetative branches; in the Halonial branches characteristic of the genus Lepidophloios the tubercles may perhaps mark the points of insertion of pedunculate strobili.

In the lax strobili the sporangiophores, which are not peltate, but strap-shaped, were borne, as C. E.

Other cones, however, namely, those known as Pothocites, have also been attributed on good grounds to the genus Archaeocalamites; they are long strobili, constricted at intervals, and it is probable that the succession of fertile sporangiophores was interrupted here and there by the intercalation of sterile bracts, which may also have been present, at long intervals, in Renault's species.

In certain cases the strobili of Palaeozoic Calamarieae appear to have had essentially the same organization as in the recent genus, the axis bearing sporangiophores only, without intercalated bracts.

In most other respects the two genera agree; there is evidence for the occurrence of heterospory in some strobili referred to Palaeostachya.

Strobili of the Calamostachys type occur in connexion both with Annularia and Asterophyllites foliage.

Four main types of structure may be distinguished among Calamarian strobili.

Almost all strobili of the Calamarieae are constructed on the same general lines as those of Equisetum, with which some agree exactly; in most, however, the organization was more complex, the complexity consisting in the intercalation of whorls of sterile bracts, between those of the sporangiophores.

G, Portion of a mature plant showing the creeping habit, the adventitious roots and the specialized erect branches bearing the strobili or cones.

In the other Calamarian strobili known the whorls of sporangiophores are separated by whorls of bracts.
