Eriocaulon shrirangii (Eriocaulaceae), a new species from the lateritic plateaus of Konkan region of Maharashtra, India

Abstract

A new species Eriocaulon shrirangii is described and illustrated here from Konkan region of Maharashtra, India. The new species is allied to E. belgaumensis with rosulate and linear leaves, length of peduncles, c. 2 mm across heads and cells of seed coat transversely elongated, aligned in vertical rows, but differs in its oblanceolate floral bracts; pedicellate male flowers; linear-lanceolate sepals of female flower, hairy at apex; hoary petals of female flower and appendages present on seeds.

Two new species of Lepidagathis Willd. (Acanthaceae: Barlerieae) from India

“…This is probably owing to their unique geological and ecological specializations, soil availability, water availability and environmental extremes (Kulkarni et al, 2022). In the last five years, a total of six new species have been described from these lateritic plateaus (Natekar et al, 2019;Biju et al, 2020;Borude et al, 2020;Chandore et al, 2020;More et al, 2022More et al, , 2023, which corroborates the need to designate the lateritic plateaus (rocky outcrops) as one of the major centres of species diversity in India. Besides these new species, the detailed taxonomy of two low-elevation lateritic plateau species that are endemic to Kerala, L. ananthapuramensis V.S.A.Kumar, P.Biju, Sindhu Arya, Josekutty & Augustine and L. keralensis Madhus.…”

Two new heterotypic synonyms in Lepidagathis Willd. (Acanthaceae: Barlerieae) from India

“…Intensive field exploration has been carried out across India during 2021-2023, especially in type localities to collect Lepidagathis species based on data taken from specimens housed in various herbaria and the published literature (Nees von Esenbeck, 1832, 1841, 1847Dalzell, 1850Dalzell, , 1851Anderson, 1867;Clarke, 1885;Cooke, 1905;Gamble, 1924) including the protologues of recently described species (Madhusoodanan & Singh, 1992;Remadevi & Binojkumar, 2008;Jithin & Jose, 2017;Natekar et al, 2019;Biju et al, 2020;Borude et al, 2020;Chandore et al, 2020;Prasad & Reddy, 2020;Dhatchanamoorthy et al, 2022;More et al, 2022More et al, , 2023Brahmadande & Nandikar, 2023;Gnanasekaran et al, 2023b). Detailed descriptions documenting the complete range of morphological variation for all species under consideration (L. decumbens Dhatchan.…”

Lepidagathis spinosa (Barlerieae: Acanthaceae), a steno-endemic species of Tamil Nadu, India: its taxonomy, lectotypification and distribution

“…(Barlerieae: Acanthaceae) is distributed mainly in the tropical and subtropical regions of the world with 147 accepted species (POWO, 2022). It is represented by 30 species and seven varieties in India (Arisdason et al, 2020;Biju et al, 2020;Chandore et al, 2020;Prasad & Reddy, 2020;More et al, 2022), of which 18 species and one variety are endemic.…”
