Selaginella canaliculata Selaginella selaginoides Selaginella willdenowii is known for its iridescent colours. There are about 750 known species of Selaginella. [21] They show a wide range of characters; the genus is overdue for a revision which might include subdivision into several genera. [citation needed] Species of spikemoss include:
The microspore has three different types of wall layers. The outer layer is called the perispore, the next is the exospore, and the inner layer is the endospore.The perispore is the thickest of the three layers while the exospore and endospore are relatively equal in width.
The tumbleweed diaspore disperses seeds, but the tumbleweed strategy is not limited to the seed plants; some species of spore-bearing cryptogams—such as Selaginella—form tumbleweeds, and some fungi that resemble puffballs dry out, break free of their attachments and are similarly tumbled by the wind, dispersing spores as they go.

Selaginella selaginoides is a non-flowering plant of the spikemoss genus Selaginella with a wide distribution around the Northern Hemisphere. It resembles a moss in appearance but is a vascular plant belonging to the division Lycopodiophyta .
Microscopic photo of spores (in red) of Selaginella. The large three spores at the top are megaspores whereas the numerous smaller red spores at the bottom are microspores. Megaspores, also called macrospores, are a type of spore that is present in heterosporous plants. These plants have two spore types, megaspores and microspores.
Selaginella lepidophylla is a small, fern-like plant with delicate, green stems and leaves. The plant forms a low, spreading mat, and it reproduces by spores. Selaginella lepidophylla grows in dry, sandy soils in full sun. The striking feature of Selaginella lepidophylla is its adaptation to conditions of prolonged drought in its natural ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
