Habit and Habitat of Selaginella: Selaginella is the only living genus of the order Selaginellales and is commonly known as ‘spike moss’ or ‘small club moss’. Phylum Lycophyta (or Lycopodophyta) -- club mosses or ground pines or lycopods Lycophyta comprises only five or six extant genera (many more extinct taxa) of which three occur in Texas. This turns out, today, to be a group of around 45-50 species also known as the Articulatae, since his genus Didiclis/Gymnogynum was based on Selaginella plumosa.

[citation needed] Some modern authors recognize three generic divisions of Selaginella: Selaginella, Bryodesma Sojak 1992, and Lycopodioides Boehm 1760. spikemosses include: A few species of Selaginella are desert plants known as "resurrection plants", because they curl up in a tight, brown or reddish ball during dry times, and uncurl and turn green in the presence of moisture. It is a large genus comprising of about 700 species distributed all over the world.

The stems are aerial, horizontally creeping on the substratum (as in Selaginella kraussiana), sub erect (Selaginella trachyphylla) or erect (as in Selaginella erythropus). In this state, they may roll up into brown balls and be uprooted, but can rehydrate under moist conditions, become green again and resume growth. Selaginella is a single genus in its family which has between 700 and 800 described species. [1] The name Selaginella was erected by Palisot de Beauvois solely for the species Selaginella selaginoides, which turns out (with the closely related Selaginella deflexa) to be a clade that is sister to all other Selaginellas, so any definitive subdivision of the species into separate genera leaves two taxa in Selaginella, with the hundreds of other species in new or resurrected genera. denticulata Spring, Selaginella apoda var. ex A.Braun.

Scientific Name Selaginella P.Beauv. Selaginella is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses. In the Manual of Pteridology,[7] the following classification was used by Walton & Alston: However, this is now known to be highly paraphyletic in most of its groupings. Both of the latter two families have only one genus each— Selaginella with about 700 species and Isoetes with about 100. with about 100. Some of the species popularly cultivated and actively available commercially include: Genus of vascular plants in the family Selaginellaceae. What does . This is a ligulate genus. Two recent classifications, employing modern methods of phylogenetic analysis, are as follows: There are about 750 known species of Selaginella. There are about 1,200 species today in three lycophyte families: Lycopodiaceae, Selaginellaceae, and Isoetaceae. [2], Selaginella species are creeping or ascendant plants with simple, scale-like leaves (microphylls) on branching stems from which roots also arise. Its genome has been sequenced by the United States Department of Energy's Joint Genome Institute. Scouring-Rush Vascular Plants Ophioglossoid Ferns (Ophioglossales) ) 1. [10] They show a wide range of characters; the genus is overdue for a revision which might include subdivision into several genera. 500-506. The largest genus of seed-free vascular plants Selaginella alone constitutes the family Selaginellaceae, the largest of the lycophyte families. Under dry conditions, some species of Selaginella can survive dehydration.

Beyond this, their study split the remainder of species into two broad groups, one including the Bryodesma species, the Articulatae, section Ericetorum Jermy and others, and the other centered on the broad Stachygynandrum group. Label the fern diagrams (Figure Lycopodioides would include the North American species S. apoda and S. eclipes, while Bryodesma would include S. rupestris (as Bryodesma rupestre).

Stem section shows the presence of more than two protosteles. The first major attempt to define and subdivide the group was by Palisot de Beauvois[4] in 1803-1805. (1938): Manual of Pteridology: J. Walton and A. H. G. Alston, Lycopodinae, pp. A number of Selaginella species are popular plants for cultivation, mostly tropical species. Some scientists[who?] Phylogenetic studies by Korall & Kenrick[5][6] determined that the Euselaginella group, comprising solely the type species, Selaginella selaginoides and a closely related Hawaiian species, Selaginella deflexa, is a basal and anciently diverging sister to all other Selaginella species.
