Sorry, no etymologies found.
-- In Ceterach the same thing occurs precisely, with this difference, that the _capita_ of the ramenta are highly developed; and still more, that the terminations of each pinnula of the young frond, are mere scales without a terminal _head_.
They are to be seen in all stages of development on the pinnae of a very young frond, those near its base having perhaps effected their purpose, while those at the apex of the pinna, or the prolonging part of pinnula, may be formed of only one cell.
No one can look at a young pinnula at this epoch and observe the evident capitation of each ramentum, the inflexion of its apex, so that the head is brought into contact with the frond, without suspecting that they have the same relation of _cause_ to the appearance subsequently of the thecae or capsules.
