Impatiens parasitica Bedd. is an epiphytic balsam, endemic to the southern Western Ghats of India. Maximum entropy distribution modelling (MaxEnt) was used for predicting the potential habitat suitability for this species. The Area Under the receiver operating characteristics Curve (AUC) value for training and test (0.95 and 0.817) is higher than 0.8, hence the model can be accepted. Jackknife test illustrates that temperature seasonality is the most contributing variable and Terrain Ruggedness Index (TRI) is the least contributed variable. The model predicted high suitability in the evergreen and semi-evergreen forests of the southern Western Ghats.

Neohouzeaua dullooa and Pseudostachyum polymorphum, two mainland bamboo species are being confirmed for Andaman and Nicobar Islands.

Despite numerous explorations and in-depth studies in the Western Himalaya on various themes, many areas still remain under-explored. One such under explored area is Asan conservation reserve. We documented for the first time the diversity of vascular plants of Asan conservation reserve, A first Ramsar site in Uttarakhand, recording the occurrence of 266 species distributed among 214 genera and 80 families within 4 km² area. Among the enumerated species, 256 are angiosperms and 10 species are Pteridophytes. Of the angiosperms, Fabaceae is the dominant family spanning 22 species followed by Poaceae (18 species), Asteraceae (16 species), and Araceae and Solanaceae consisting of 10 species each. Documenting and understanding this flora is crucial for conservation efforts and scientific exploration. The present study provides an updated checklist of the vascular flora in the Asan Conservation Reserve, throwing light on its botanical richness and ecological significance.

Nahar or Mesua ferrea Linn. (Family Calophyllaceae) is a slow-growing, moderate to large-size evergreen tree species. Arbuscular Mycorrhize (AM) are well-known symbiotic partners that provide specific nutrients thus increase overall plant growth. The present study was undertaken to identify potential AM associates of M. ferrea for enhanced growth and survival. M. ferrea was recorded as a regular mycorrhizal species with high AM diversity at all stages of its lifecycle. Glomus, was the most abundant genus (15 species). The maximum AM species and spores were recorded at seedling stage (31; 96±4.67/100g of soil), while mature trees had the least numbers (11; 80±1.52). Total phosphorus was highest in the rhizosphere soil when number of AM spores was the lowest and root infection percentage was the highest. Glomus constrictum and G. feugianum, recorded with higher density (18.33±3.61and 31.00±7.55 spores/100g of soil respectively) and relative abundance (7.01% and 11.85% respectively), were selected to study their effect on growth and survival of M. ferrea seedlings. G. feugianum was found most suitable species with enhanced height growth (~172%) and seedling survival rate (80%) as compared to G. constrictum, both AM species together and control. Thus, G. feugianum may be used as potential mycorrhizal inoculant for sustainable M. ferrea plantation programme.

Piper retrofractum Vahl, (Piperaceae L.) is reported here for the first time from state of West Bengal near the coast of Purba Medinipur. The paper deals with detailed description based on vegetative and reproductive parts, and pollen morphology. Key for the identification of the species found in the state and ecological notes are given.

During floristic survey in August 2022, Boerhavia erecta L. (Nyctaginaceae) was collected from Sonbhadra district of Uttar Pradesh, India. A taxonomic description of the plant along with photographs is provided for easy identification.

We conducted rapid survey of bryoflora in alpine areas of East Sikkim. The study revealed the presence of 49 distinct bryophyte taxa, with a significant representation from the Pottiaceae, Leucobryaceae, and Grimmiaceae families. Remarkably, this survey contributes 12 taxa as novel records for Sikkim. Among the bryophytes catalogued, 45 belong to the mosses, while four are liverworts, collectively spanning 18 families, which include 15 moss families and three liverwort families. The predominant growth forms observed are characterized by cushions, mats, or turfs, underscoring the adaptability of these bryophytes to diverse substrates and microenvironments.

Iphigenia magnifica and Paspalum canarae are reported here for the first time from Madhya Pradesh state. Detailed descriptions, photo plates and relevant notes are provided for easy identification.

In the present paper Blumea balsamifera (Asteraceae) is reported for the first time from the Terai region of eastern part of Uttar Pradesh state in India. It is earlier known to occur from eastern Himalaya in Sikkim, Assam to West Bengal, Andaman and Nicobar Islands, and Madhya Pradesh. A detailed description, information on its phenology, habitat, distribution, threat and photographic illustration have been provided for easy identification.

Hydrocotyle verticillata Thunb., (Araliaceae) is being reported for the first time from Manipur, North East India. A detailed description, phenology, habitat and distribution of the species is provided.
