(iv) Therefore, it becomes evident that the heterosporous vascular cryptogam, Selaginella, has considerably advanced towards seed habit in some species but its approach to the true seed is not complete due to the following reasons: (a) The megasporangium wall is dehiscent and is not covered with the protective integuments. Selaginella is neither a fern nor moss but a vascular plant; however, instead of moss, it is more a fern alley technically based on temperament and attitude related to care and growth. The mesophyll consists of loosely arranged spongy parenchyma with intercellular spaces. Resurrection Plant Care . The site of sporangial initiation (micro- or mega-sporangium) is in superficial cells of the axis, directly above the sporophyll, or in cells near the base of the sporophyll on the adaxial (upper) side. Rhizophore is (a leafless structure where from roots arises) present in some species. Examples include: Anastatica hierochuntica, also known as the Rose of Jericho, a plant species native to deserts of North Africa. In some species, only one megasporangium is present at the base of each strobilus, while the rest are microsporangia (e.g., S. kraussiana). There is variation in distribution of sporangia within the strobili of different species. In S. rupestris, the trailing branches of the stem develop adventitious branches, that separate from the parent plant and grow into new sporophyte. Regardless of the stelar organisation, the primary xylem is exarch in development and the metaxylem consists primarily of tracheids with scalariform pittings.

Selaginella shows considerable variation in size, symmetry and morphology. How is oxygen transported by the circulatory system? Species with radial symmetry may have a single, cylindrical proto- stele in the stem (monostelic e.g., S. spinulosa, S. flabellata), whereas dorsiventral species may have two (e.g., distelic e.g., S. kraussiana) or more vascular strands (12-16 steles) (polystelic e.g., S. laevigata) that are either circular or ribbon-shaped. In some species, the outer layers of cortex become sclerenchymatous and form hypodermis.

The antherozoids (sperms) are free-swimming type, very narrow and about 15-50 pm in diameter at about the middle of the sperm/antherozoid. Selaginella produces spores like ferns for reproduction than seeds. The primary neck cell does not divide further so that a neck canal cell is formed, while the primary venter cell divides transversely into a ventral canal cell and an egg (Fig. Thus, the central stele is separated from the cortex by large air spaces. 5.8k.
