Its branching pattern is relatively regular, contributing to a highly textured and delicate appearance. The stems are slender and serve as the primary structural support for the tightly packed foliage.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, specifically found in countries like Thailand, Malaysia, Indonesia, and parts of southern China. It typically inhabits moist, shaded environments such as rainforest floors and rocky crevices where humidity remains high. The species thrives in lowland areas that experience consistent rainfall throughout the year. Its distribution is closely tied to specific microclimates that support the growth of various lycophytes. This restricted range makes its presence highly dependent on the preservation of intact forest ecosystems.
How is this plant cultivated?
This plant requires a consistently moist, well-draining substrate consisting of peat moss and perlite kept in high humidity and bright, indirect light.
To prevent the fronds from drying out, maintain an environment with humidity levels above sixty percent. Avoid placing the specimen in direct sunlight, as intense rays can scorch the delicate leaves. Watering should be frequent enough to keep the soil damp but not waterlogged to prevent root rot.
This species thrives best in terrariums or shaded indoor areas where moisture levels remain stable.

According to a study published by "Current issues in molecular biology", the genome of Selaginella moellendorffi v1.0 contains ten novel, chitin-specific Hevein-like lectins. These lectin homologs show the capacity to bind with the spike protein of SARS-CoV-2, specifically interacting with the receptor binding domain. The Smo446851, Smo125663, and Smo99732 lectins exhibited binding free energies of -17.5, -13.0, and -26.5 Kcal/mol, respectively. Molecular dynamics simulations and normal-state analyses via iMODS showed that the Smo99732-RBD complex possessed higher stability and minimum deformity compared to other lectin complexes. These in silico findings suggest these lectin candidates can target key N-glycan sites crucial to viral virulence and infection.

According to a study published by "Plant biotechnology journal", Selaginella moellendorffii contains the bifunctional diterpene synthase SmMDS which catalyzes the cyclization of (E,E,E)-geranylgeranyl diphosphate to miltiradiene. This miltiradiene serves as a crucial precursor of important medicinal compounds such as tripitolide, ecabet sodium and carnosol. Through mutagenesis studies, researchers confirmed that pimar-15-en-8-yl+ is an intermediate in this synthesis process. The study also confirmed the copa-15-yl+ intermediate and determined the apo-state and the GGPP-bound state crystal structures of SmMDS. These findings unveil details regarding the catalysis process in the SmMDS class I active site and the movement of (+)-CPP from the class II active site.
