KAMRUL HAQUE , SALEH AHAMMAD KHAN, SARDER NASIR UDDIN AND SHAYLA SHARMIN SHETU Department of Botany, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh Keywords: Checklist; Angiosperms; Rajkandi Reserve Forest; Moulvibazar. Abstract This study was carried out to provide the baseline data on the composition and distribution of the angiosperms and to assess their current status in Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study reports a total of 549 angiosperm species belonging to 123 families, 98 (79.67%) of which consisting of 418 species under 316 genera belong to Magnoliopsida (dicotyledons), and the remaining 25 (20.33%) comprising 132 species of 96 genera to Liliopsida (monocotyledons). Rubiaceae with 30 species is recognized as the largest family in Magnoliopsida followed by Euphorbiaceae with 24 and Fabaceae with 22 species; whereas, in Lilliopsida Poaceae with 32 species is found to be the largest family followed by Cyperaceae and Araceae with 17 and 15 species, respectively. Ficus is found to be the largest genus with 12 species followed by Ipomoea, Cyperus and Dioscorea with five species each. Rajkandi Reserve Forest is dominated by the herbs (284 species) followed by trees (130 species), shrubs (125 species), and lianas (10 species). Woodlands are found to be the most common habitat of angiosperms. A total of 387 species growing in this area are found to be economically useful. 25 species listed in Red Data Book of Bangladesh under different threatened categories are found under Lower Risk (LR) category in this study area.

Hence, there is a tendency of species misidentification using only the mor- phological characters. Herein, we evaluated the discriminatory power of the universal DNA barcodes (matK and rbcL) for 53 species spanning the two families. Using these markers, we inferred phylogenetic relation- ships and conducted species delimitation analysis using four delimitation methods: Automated Barcode Gap Discovery (ABGD), TaxonDNA, Bayesian Poisson Tree Processes (bPTP) and General Mixed Yule Coalescent (GMYC). The phylogenetic reconstruction based on the matK gene resolved the relationships between the families and further suggested the expansion of the Lamiaceae to include some core Verbanaceae genus, e.g., Gmelina.

  • West Indian Weed Woman: Indigenous Origins of West Indian Folk Medicine
    WEST INDIAN WEED WOMAN: INDIGENOUS ORIGINS OF WEST INDIAN FOLK MEDICINE WEST INDIAN WEED WOMAN: ORÍGENES INDÍGENAS DE LA MEDICINA POPULAR DE LAS INDIAS OCCIDENTALES WEST INDIAN WEED WOMAN: ORIGINES AUTOCHTONES DE LA MÉDECINE FOLKLORIQUE DES INDES OCCIDENTALES Erneslyn Velasco and Lawrence Waldron Erneslyn Velasco, R.N Elmhurst Hospital Center, United States Lawrence Waldron, Ph.D. Queens College, City University of New York, United States [email protected] In one of many versions of the popular early twentieth century calypso, “West Indian Weed Woman,” the song’s namesake (an unusual street vendor encountered by the singer, Bill Rogers) lists over sixty herbal folk remedies. After carefully transcribing the popular names of the herbs mentioned in the song, the investigators proceeded to locate the botanical names of the species. In the process, they discovered that more than half were endemic to the Caribbean and South America. Further research revealed that all of these endemic herbs have Indigenous medicinal applications, some of which are mentioned in the verses of the Rogers calypso. Thus, the song represents not only an intersection between West Indian folk medicine and popular culture and music, but reveals the extent to which Amerindian pharmacology was retained by an overarching Afro-Caribbean culture during the colonial and early modern period of the region. En una de las muchas versiones del calypso popular de principios del siglo XX, "West Indian Weed Woman", el homónimo de la canción (un vendedor callejero inusual encontrado por el cantante, Bill Rogers) enumera más de sesenta remedios herbales populares. Después de transcribir cuidadosamente los nombres populares de las hierbas mencionadas en la canción, los investigadores procedieron a localizar los nombres botánicos de la especie.

Steenis, in Indonesian is binahong, is a creeping plant with a length can reach 6 meters. Binahong originated from the United Stated and be classified in Family Basellaceae. In Indonesia, binahong often be used for traditional medicines to treat diabetes, relieve shortness of breath, stabilize blood pressure, coughing and vomiting blood, lung disease, accelerate wound healing process, restoring bruised, headache, hives, immune system, nose bleeding, prevent stokes and health problems after the surgery and childbirth. Binahong contains several active compounds, such as saponins, alkaloids, polyphenols, flavonoids, and glycosides that have an effect on the wound healing process. The extract of binahong leaf is made to retain the active compound content which is inside the leaf binahong in order to still have effect as anti-inflammatory, antioxidant, antibacterial, and as an analgesic.

    GUIDE TO THE GENERA OF LIANAS AND CLIMBING PLANTS IN THE NEOTROPICS BASELLACEAE By Pedro Acevedo-Rodríguez (Feb 2020) A family of 4 genera and about 20 species of succulent twining vines with scant secondary growth, with new stems produced from fleshy underground tubers; less often erect or trailing herbs (Ullucus). Represented in the Neotropics by 3 genera and 13 species of vines. A family with tropical distribution but most diverse in sub-paramo regions of the Andes in South America. Diagnostics: Succulent, twining vines, usually a few m long, with clear or mucilaginous exudate; leaves alternate, simple, fleshy, with entire (except Tournonia), light colored or reddish margins; flowers small; underground parts tuberous. General appearance similar to Phytolaccaceae but Basella alba, photo by P. Acevedo distinguished by being herbaceous and having odorless leaves. General Characters 1. STEMS. Most species have herbaceous stems which usually are reddish tinged with scant secondary growth, mostly cylindrical. Two species of Anredera and known to have stems that can reach several cm in diameter and many m in length. Anredera baselloides (Kunth) Baill is reported to reach 2.5 cm in diam at the base of cultivated plants and few meters long; A. tucumanensis (Lillo & Hauman) Sperling, can reach 5 cm or more in diam., and up to 12 m in length. In most species, the stems die back, and new stems are produced from a tuberous base. Stems of Anredera baselloides (Kunth) Baill. and Basella rubra L. (= B. alba L.) have been reported as having successive cambia that produce isolated strands of vascular tissue.

The phylogeny of a phylogenetically poorly known family, Phytolaccaceae sensu lato (s.l.), was constructed for resolving conflicts concerning taxonomic delimitations. Cladistic analyses were made based on 44 sequences of the internal transcribed spacer of nuclear ribosomal DNA from 11 families (Aizoaceae, Basellaceae, Didiereaceae, Molluginaceae, Nyctaginaceae, Phytolaccaceae s.l., Polygonaceae, Portulacaceae, Sarcobataceae, Tamaricaceae, and Nepenthaceae) of the order Caryophyllales. The maximum parsimony tree from the analysis resolved a monophyletic group of the order Caryophyllales; however, the members, Agdestis, Anisomeria, Gallesia, Gisekia, Hilleria, Ledenbergia, Microtea, Monococcus, Petiveria, Phytolacca, Rivinia, Genetics and Molecular Research 12 (4): 4515-4525 (2013) ©FUNPEC-RP www.funpecrp.com.br J.
