The pistil, which is above the rest of the members of the flower, consists of two carpels joined at their edges to form the ovary, which becomes two-celled by subsequent ingrowth of a septum from these united edges; a row of ovules springs from each edge.
In a syncarpous pistil, on the other hand, the carpels are so united that the edges of each of the contiguous ones, by their union, form a septum or dissepiment, and the number of these septa consequently indicates the number of carpels in the compound pistil (fig.
In Terebratella the loop is attached to the hinge-plate and to the septum (fig.
This steel septum was protected on either side by a thin wall of asphaltic concrete supported by rubble stone embankments, and owing to irregular settling of 'the embankments became greatly distorted, apparently, however, without causing leakage.
Between the two corpora cavernosa the sheath is not complete and, having a comb-like appearance, is known as the septum pectinatum.
With his head encircled by a coronet of dogs teeth, and covered with a network cap or piece of bark-cloth, the septum of the nose transfixed by a pencil of bone or shell, and perhaps a shell or fibre armlet or two, the Papuan is in complete everyday attire.
At the age of puberty the lad was tattooed or scarred with gashes cut in back, shoulders, arms and chest, and the septum of the nose was pierced.
The arches bear on the convex outer side the delicate arborescent gills, and on the concave inner side develop a membranous septum with vermicular perforations, a special sifting or filtering contrivance through which the water absorbed by the mouth has to pass before reaching the respiratory organs of the branchial apparatus.
The Papuan loves personal adornment and loses no chance of dressing himself up. His chief home-made ornaments are necklaces, armlets and ear-rings of shells, teeth or fibre, and cassowary, cockatoo, or bird of paradise feathers - the last two, or a flower, are worn through the septum of the nose.
The spores themselves may be unicellular without a septum or multicellular with one or more septa.
