In the background were the beautiful layered mountains of the White Rock Wildlife Management.
Sometimes the epidermis is considerably more developed by tangential division of its cells, forming a many-layered water-tissue.
Fin, 22.Median Longitudinal Section of the Growing, Point of the Stem of HiPPurii vulgaris, showing a many-layered meristem.
That the lateral eyes of Scorpio have a single cell-layered or " monostichous " ommatidium like that of Limulus.
To the primitive two-cell-layered form, the hypothetical ancestor of all Metazoa or Enterozoa, Haeckel gave the name Gastraea; the em- bryonic form which represents in the individual growth from the egg this ancestral condition he called a " gastrula."
This is formed as a two-layered "polypide-bud," which usually develops from the inner side of the zooecial wall, and soon occupies the place of the previous polypide.
(Modified from Horst.) A, Blastula stage (one-cell-layered eaten its way into the in sac), with commencing invaginated endodermal sac, vagination of the wall of the and the cells pushed in with sac at bl, the blastopore.
From each side of the uterus the peritoneum is reflected outward, as a two-layered sheet, to the side wall of the pelvis; this is the broad ligament, and between its layers lie several structures of importance.
Unlike the cells of Protozoa, these embryonic cells of the Metazoa do not remain each like its neighbour and capable of independent life, but proceed to arrange themselves into two layers, taking the form of a sac. The cavity of the two-cell-layered sac or diblastula thus formed is the primitive gut or arch-enteron.
The orifice of invagination (blastopore) narrows, and we now have a two-cell-layered sac - the gastrula.
In effect (6) it traces the Turbellaria to small two-layered organisms consisting of an outer ciliated epidermis and a central syncytial tissue.
The skin consists of a transparent cuticle excreted by the underlying ectoderm, the cells of which though usually one-layered may be heaped up into several layers in the head; beneath this is a basement membrane, and then a layer of longitudinal muscle fibres which are limited inside by a layer of peritoneal cells.
One whole summer, sometimes two, must elapse before the layers will be fully rooted in the case of woody plants; but such plants as carnations and picotees, which are usually propagated in this way, in favourable seasons take only a few weeks to root, as they are layered towards the end of the blooming season in July, and are taken off and planted separately early in the autumn.
When a plant is too high or its habit does not conveniently admit of its being layered, it may often be increased by what is called circumposition, the soil being carried up to the branch operated on.
In most cases this can be performed with little risk, but the gleichenias, for example, must only be cut into large portions, as small divisions of the rhizomes are almost certain to die; in such cases, however, the points of the rhizomes can be led over and layered into small pots, several in succession, and allowed to remain unsevered from the parent plant until they become well-rooted.
These should be kept cut off close to the old plant, so that the full force of the root is expended in making the " crowns " or fruit buds for next season's crop. If plants are required for new beds, only the required number should be allowed to grow, and these may be layered in pots as recommended in July.
- Strawberry plants that have been layered in pots may yet be planted, or in southern districts the ordinary ground layers may be planted.
