“…Lycopods were, in spite of the low diversity seen today, an important part of the Carboniferous flora (Thomas, 1992(Thomas, , 1997, with the oldest fossil unequivocally assigned to the Selaginellaceae from the Visean epoch (333-350 million years ago; Rowe, 1988). The extant plants in the Selaginellaceae are herbaceous and found throughout the world, predominantly in the tropics, and have creeping to erect main stems.…”

“…It has dichotomous branch and minute scale-like leaves that are generally in two different sizes, where median is smaller than lateral ones (Jermy 1990). This morphological characteristic is only little change since Carboniferous period, when this plant lives in tropical wetland (Thomas 1992(Thomas , 1997.…”

“…In the late Carboniferous period (290-323 mya), Selaginella that has herb form, dichotomous branching, and small dimorphic leaf begin to widespread and constitute of coal (Thomas 1992(Thomas , 1997. Selaginella is generally abundant in forest floor; its dimorphism leaf is an adaptation to low light intensity (Hebant and Lee 1984).…”

.) is a cosmopolitan genus that grows in tropical and temperate regions. Some species of Selaginella have widely distribution and tend to be invasive, but the others are endemics or even, according to IUCN criteria, endangered. Nusantara or Malesia (Malay Archipelago) is the most complex biogeographic region and rich in biodiversity. It is one of the biodiversity hotspot of Selaginella, whereas about 200 species of 700-750 species are exist. Selaginella has been survived for 440 mya without any significant morphological modification, but extinction of tree-shaped species. Selaginella have similar morphological characteristics, particularly having heterospore form and loose strobili; and is classified as one genus and one family. However, individual species has high morphological variation caused by different edaphic and climatic factors. Genetic studies indicate high polymorphism among Selaginella species. Selaginella had been used as complementary and alternative medicines treated to postpartum, menstrual disorder, wound, etc. Biflavonoid -the main secondary metabolites -gives this benefit and is especially used as anti oxidant, anti-inflammatory, and anti cancer in modern pharmaceutical industry. The other metabolites, trehalose, potentially act as molecular stabilizer in biological based industry. Metabolite profiles can also be used to identify Selaginella by its species, time and harvest age, and locations. Since most of Selaginella grows on moist, organically rich, and well drained soils, which is vulnerable to forest degradation and global warming, it needs more conservation priority. Biosystematics and ethnobotanical researches of Nusantara Selaginella is needed to expand taxonomic status and bioprospecting of this bioresources.

“…Carboniferous herbaceous lycopsids and their cones belong to a rarely reported group of fossil plants (Thomas 1997(Thomas , 2005Bek et al 2001). Three groups of cones of Carboniferous herbaceous lycopsids can be distinguished on the basis of their in situ spores.…”

“…The best known and the most often reported are cones of herbaceous forms of the genus Selaginella Palisot de Beauvoir. All these cones produced microspores of the genus Cirratriradites Wilson & Coe [mostly C. saturni (Ibrahim) Schopf et al, see Bek et al 2001] and megaspores compared with several species of the genus Triangulatisporites (Potonié & Kremp) Karczewska (Thomas 1997, Bek et al 2001. The second group is represented by unnamed type of Selaginella-like plant (Drábková, pers.…”
