Addition of one hundred and forty-seven new vascular taxa to the flora of Bangladesh

Abstract

All 147 new vascular taxa that are added to the flora of Bangladesh in this study are not included in Flora of British India, Bengal Plants, The Encyclopedia of Flora and Fauna of Bangladesh, or Rahman's research publications. These new taxa are categorized into 111 genera and 53 families. A total of 3,956 vascular taxa have been reported for the flora of Bangladesh from this updated compilation. In addition to the seventeen genera that are being reported here as new generic records for Bangladesh, ten taxa that are novel to the world flora have been discovered. According to the study, six families, including Orchidaceae (22 taxa), Acanthaceae (18 taxa), Rubiaceae (11 taxa), Euphorbiaceae (10 taxa), Araceae (8 taxa) and Commelinaceae (6 taxa) contain the highest number of new taxa. Nomenclature, family name, citation and precise locations are listed for each taxon.

Notes on Discospermum sphaerocarpum Dalzell ex Hook.f., a rare species of Rubiaceae (Ixoroideae: Coffeeae) from southern India

“…Distribution and Ecology: The species is endemic to the Western Ghats and Sri Lanka. However, its recent reports from Philippines (Biag & Alejandro 2021) and Bangladesh (Uddin et al 2023) are doubtful, as its description or voucher specimens were not available for confirmation. In southern India, the species was recorded from the low altitude to high range (50-1,000 m) evergreen forests of the southern Western Ghats (Figure 1) (Gamble 1921;Singh et al 2015 ).…”
