Karakteristik
Selaginellas are creeping or ascendant plants with simple, scale-like leaves on branching stems from which roots also arise. Selaginellas yang merayap atau tanaman kekuasaan dengan sederhana, skala-seperti daun pada percabangan yang berasal dari akar juga muncul. The plants are heterosporous (megaspores and microspores), and have structures called ligules, scale-like outgrowths near the base of the upper surface of each microphyll and sporophyll. Tanaman yang heterosporous (megaspores dan mikrospora), dan memiliki struktur yang disebut ligules, skala-seperti outgrowths dekat pangkal permukaan atas dari masing-masing microphyll dan sporophyll.Unusually for the lycopods, each microphyll contains a branching vascular trace. Luar biasa untuk lycopods, microphyll masing-masing berisi jejak percabangan pembuluh darah.
Divisi Generik
Some modern authors recognize three generic divisions of Selaginella : Selaginella , Bryodesma Sojak 1992 , and Lycopodioides Boehm 1760 . Lycopodioides would include the native North American species S. Beberapa penulis modern mengakui tiga divisi generik Selaginella:. Selaginella, Bryodesma Sojak 1992, dan Lycopodioides Boehm 1760 Lycopodioides akan mencakup asli Amerika Utara spesies S. apoda and S. apoda dan S. eclipes , while Bryodesma would include the native S. eclipes, sementara Bryodesma akan mencakup S. asli rupestris (as Bryodesma rupestre ). Stachygynandrum is also sometimes used to include the bulk of species. rupestris (sebagai Bryodesma rupestre). Stachygynandrum juga kadang-kadang digunakan untuk memasukkan sebagian besar spesies.The first major attempt to define and subdivide the group was by Palisot de Beauvois in 1803-1805. Upaya besar pertama untuk mendefinisikan dan membagi kelompok itu oleh Palisot de Beauvois di 1803-1805. He established the genus Selaginella as a monotypic genus, and placed the bulk of species in Stachygynandrum . Gymnogynum was another monotypic genus, but that name is superseded by his own earlier name of Didiclis . Dia mendirikan Selaginella genus sebagai genus monotypic, dan ditempatkan sebagian besar spesies dalam Stachygynandrum Gymnogynum adalah genus lain monotypic,. Tetapi nama yang diganti dengan nama sendiri sebelumnya tentang Didiclis. This turns out, today, to be a group of around 45-50 species also known as the Articulatae , since his Didiclis/Gymnogynum genus was based on Selaginella plumosa . Ini ternyata, hari ini, untuk menjadi kelompok sekitar 45-50 spesies juga dikenal sebagai Articulatae, karena nya Didiclis / Gymnogynum genus didasarkan pada Selaginella plumosa . He also described the genus Diplostachyum to include a group of species similar to Selaginella apoda . Spring inflated the genus Selaginella to hold all selaginelloid species four decades later. Dia juga menggambarkan Diplostachyum genus untuk menyertakan kelompok spesies mirip dengan Selaginella apoda. Musim Semi menggelembungkan Selaginella genus untuk menampung semua spesies selaginelloid empat dekade kemudian.
Phylogenetic studies by Korall & Kenrick determined that the Euselaginella group, comprising solely the type species, Selaginella selaginoides and a closely related Hawai'ian species, Selaginella deflexa , is a basal and anciently diverging sister to all other Selaginella species. Filogenetik studi oleh Korall & Kenrick ditentukan bahwa kelompok Euselaginella, terdiri hanya spesies jenis, Selaginella selaginoides dan Hawai'ian terkait erat spesies, Selaginella deflexa, adalah adik zaman dahulu basal dan divergen untuk semua spesies Selaginella lainnya . 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 around the broad Stachygynandrum group. Selain ini, penelitian mereka membagi sisa spesies menjadi dua kelompok yang luas, termasuk spesies Bryodesma, Articulatae, bagian Ericetorum Jermy dan lain-lain, dan yang lainnya berpusat di sekitar kelompok Stachygynandrum luas.
