“…This may be due to different developmental stages of the spores. Our results on microspores of S. reticulata differ from those reported by Singh et al (2020). We found major similarities in the shape and ornamentation of microspores of S. reticulata reported by Singh et al (2020) to those of S. miniatospora reported by Singh et al (2016).…”

“…Selaginellaceae Willk. is the family of fern allies comprising the largest group within the lycophytes (Christenhusz et al 2011; Setyawan 2011; Zhou et al 2015) consisting of 750–800 species distributed worldwide (Shalimov et al 2019; Zhou et al 2022) and about 59 species in India (Jenkins et al 2016; Singh et al 2020). The members of the family are herbaceous, having different growth forms, and heterosporous.…”

“…In India, taxonomical studies on the genus have been carried out by various workers (Dixit 1992; Madhusoodanan and Nampy 1994; Antony et al 2002; Ghosh 2004; Nisha et al 2010; Singh et al 2012; Fraser-Jenkins 2016). However, studies on microscpores morphology using a scanning electron microscope (SEM) are sparse and have been carried out only on 10 species (Singh et al 2016), leaving many other Indian species unexamined (Fraser-Jenkins et al 2017; Singh et al 2020). In the present work, we undertake a detailed analysis of microscpores size, color, shape, proximal surface, distal surface, lateral surface and surface ornamentation in 18 species of Selaginellaceae from Arunachal Pradesh, using a light microscope (LM) and SEM.…”

The microspores morphology of 18 species of Selaginellaceae found in Arunachal Pradesh, North East India, is studied using light microscopy and electron microscopy. Of the 18 taxa examined here, the study of five taxa is attempted for the first time using an electron microscope. The species studied exhibit variation in size, shape, color and ornamentation of the microscpores. The equatorial diameter ranges from 11 to 57 mm. The tetrad form of the microscpores is recorded in four species. The variations in the microscpores ornamentation within the species of the family are useful in identification, classification and taxonomic distinction of the species. An identification key is provided for the species under study. This research is beneficial for the enumeration of basic information of microspores of the family and for the precise identification of Selaginella species. Statistical analysis of the distal and proximal surface ornamentation of the microspores is also provided.

We describe a new species of the genus Selaginella from Arunachal Pradesh. The proposed taxon is collected from hill slopes of Wakka, a town in Longding district of Arunachal Pradesh, India. The described species is based on variation in spore morphology and features of median leaves. The variation recorded in spore morphology came into light when freshly collected samples were analysed under an electron microscope. The species is morphologically distinct and is very close to two species i.e., S. reticulata and S. odishana. Taxonomic keys and a table are added to separate and compare the three species respectively. Diagnosis, description and relevant photo plates are provided for easy identification of the species.

The present study was carried out to record the color, size, and ornamentation of megaspores in 18 species of the family Selaginellaceae from Arunachal Pradesh using scanning electron microscope (SEM) and light microscope (LM). Electron microscopic study of the spore features revealed the type of ornamentation and microsculptural detail. SEM study on megaspore of Selaginella pentagona (S. pentagona), Selaginella tenuifolia, Selaginella semicordata, and Selaginella chrysorrhizos is presented for the first time. Variation in the megaspore ornamentation is noted at the interspecific level and intraspecific level in some cases. Examination of the megaspores under study found all the megaspores as trilete, with a size ranging from 116 to 560 μm in diameter. Taxonomic key is prepared to differentiate the species. Short descriptions of megaspores are provided and supported by photo plates. New features are recorded for seven species. The study contributes to the separation of species within the genus Selaginella based on the spore feature and brings forward the use of spore as a diagnostic tool in the taxonomy of the genus. These works contribute to the systematic of the family Selaginellaceae and provide useful information in the field of palynology.Research Highlights Study on megaspore features of Selaginella species collected from Arunachal Pradesh, using SEM and LM. Taxonomic key is provided for each species based on megaspores features. New megaspore features are recorded for the seven species. The study brings forward the use of spore as a diagnostic tool in the taxonomy of the genus. These works provide useful information in the field of systematic and palynology.
