The aim of the present study is to investigate the methanolic extract of the roots of Murdannia lanuginosa and M. Simplex (Commelinaceae) for their phytochemical compounds using Gas Chromatography–Mass Spectrometry (GC-MS). The study reveals three compounds in M. lanuginosa and six compounds in M. simplex respectively. M. lanuginosa could be used for antimicrobial, anti-inflammatory and anti-proliferative activity due to the presence of secondary metabolites like 4H-Pyran-4- one, 2, 3-dihydro-3,5-dihydroxy-6-methyl (Retention time 8.659) in the methanolic extract. While M . simplex extracts may be used in the development of fungicidal agent due to the presence of Salicylaldehyde, Azine (Retention time 22.608) as a major compound which is known for its fungicidal activity. A further study in the present taxa and family Commelinaceae is warranted to determine active principle of the extract as well as to elucidate their exact mechanism of action in various disorders.

The forts on hilltops of the Sahyadri (northern Western Ghats) have seen a turbulent historical past and are famous for their architectural style and cultural heritage. Besides this, these hilltops are home to an incredible plant diversity. One of the highest hilltop forts (ca. 1,403m) the Torna, has been explored since 2012 for floral assessment. The study documented ca. 399 plant species of which about 28% are endemic to the Western Ghats and 16 monotypic species were recorded. A brief account of the immense floristic diversity and new findings from Torna fort are summarized in the present article.

An identification key to all the reported species of Hedyotis-Oldenlandia group (Hedyotis, Oldenlandia, Exallage, Leptopetalum, Scleromitrion and Debia) in Andaman & Nicobar Islands is presented with one new species, Oldenlandia smita-crishnae, described from Saddle Peak forests of North Andaman, India. It shares some characters with Oldenlandia herbacea, O. corymbosa and O. pseudocorymbosa. However, it is remarkable for its abaxially puberulous leaves, divaricate stipules, ellipsoid to obovoid hypanthium, pink-striped corolla lobes and 20–30-seeded, inserted capsule. Furthermore, a new combination in Exallage is proposed and lectotypes for Spermacoce cristata, S. costata, Hedyotis vestita and Oldenlandia stocksii are designated.

In India, the delimitation and taxonomic status of the genus Microcos has historically been in a state of flux. While revising the genus Grewia for India, authors found certain taxonomic and nomenclatural inconsistencies in the Floras while treating M. paniculata and M. calophylla . The aims of the present study are to resolve these inconsistency, to review the genus Microcos in India, and the lectotypification of M. calophylla (≡ Grewia calophylla ).

The root parasitic species of Christisonia Gardner (Orobanchaceae) are lectotypified. After screening of herbarium specimens and the results of field expeditions, the morphological characters and distribution of Chritisonia lawii are within the range of C. calcarata. As a result, it is reduced to C. calcarata.

The genus Salacia (Celastraceae: Salaciodeae) in peninsular India is revised, wherein ten species are recognised. Eight species are endemic to the region. Salacia macrophylla and S. reticulata are excluded from the revision as occurrence of both the species is doubtful in mainland India. Salacia macrosperma exhibits great variation in leaf shape, flower number, pedicel length and fruit texture, hence the morphologically similar species S. beddomei and S. vellaniana are relegated to its synonymy. Descriptions, photographs, and pen and ink as well as colour drawings of all recognised Salacia species are provided with an artificial key, updated nomenclature, and synonymy. Distribution and IUCN Red list categories and criteria are also discussed. Seven binomials, S. fruticosa, S. macrophylla, S. macrosperma, S. oblonga, S. ovalis, Tontelea prinoides and Johnia coromadeliana are lectotypified.

We recognize four species of Ledebouria Roth (Hyacinthaceae: Hyacinthoideae) from India, namely Ledebouria revoluta (L.f.) Jessop, Ledebouria viridis S. Dutta & P. Harvey ex M.R. Almeida, Ledebouria karnatakensis Punekar & Lakshmin. and Ledebouria hyderabadensis M.V. Ramana et al. The name Ledebouria junnarensis S.S. Rahangdale & S.R. Rahangdale is a later superfluous name for L. viridis. Lectotypes are designated for Ledebouria hyacinthina Roth & Bernardia indica Wight. Scilla hohenackeri Fischer & Mayer, earlier enumerated from India, is known from Pakistan and Central Asia, and is therefore, excluded from this work. We describe all four species, with their synonymy and updated nomenclature.

In the course of revising the family Commelinaceae in India, it has been found that no type was indicated in the protologue of Streptolirion volubile Edgew. Thus, it warrants typification under execute Art. 9.2 of the International Code of Nomenclature (McNeill & al. 2012). Though not cited explicitly in the protologue, we consider Edgeworth’s own material collected in 1844 from the Indian Himalaya and annotated by him to constitute original material and therefore appropriate for typification. We herein designate a specimen at Kew that unequivocally agrees with the protologue as lectotype.

The genus Flemingia Roxb. ex Ait. & Ait. f. is represented by c. 30 species distributed in the old world tropics. India is home to 16 species and 2 variety of which 5 species and 1 variety are endemic. The genus is of great economic potential as some species are source of dyes while others are used as root crops. In addition to this Flemingia is one of the wild relatives of Cajanus cajan (L.) Millsp.(pigeonpea). Keeping all this in mind, the present paper aims at karyotypic studies in F. nilgheriensis (Baker) Wight ex T. Cooke, an endemic plant species ...
