Species evaluated include Mussaenda afzelii (wild), M. erythrophylla, M. philippica and Pseudomussaenda flava. Different concentrations of NAA phytohormone were applied to the cuttings grown in mixed river sand and saw dust (1:1; v/v); and laid out in a 4 x 4 factorial experiment in completely randomized design (CRD; r=4). Results showed that increasing concentrations of NAA application slowed down emerging shoot bud in M. afzelii, P. flava, M. erythrophylla and M. philippica. While other species responded positively at some point to increased concentrations of the NAA applications, the P. flava showed retarding effect of phytohormone treatment on its number of leaves.

  • Molecular Support for a Basal Grade of Morphologically
    TAXON 60 (4) • August 2011: 941–952 Razafimandimbison & al. • A basal grade in the Vanguerieae alliance MOLECULAR PHYLOGENETICS AND BIOGEOGRAPHY Molecular support for a basal grade of morphologically distinct, monotypic genera in the species-rich Vanguerieae alliance (Rubiaceae, Ixoroideae): Its systematic and conservation implications Sylvain G. Razafimandimbison,1 Kent Kainulainen,1,2 Khoon M.

Box 392, Victoria, Mahé, Seychelles Author for correspondence: Sylvain G. Razafimandimbison, [email protected] Abstract Many monotypic genera with unique apomorphic characters have been difficult to place in the morphology-based classifications of the coffee family (Rubiaceae). We rigorously assessed the subfamilial phylogenetic position and generic status of three enigmatic genera, the Seychellois Glionnetia, the Southeast Asian Jackiopsis, and the Chinese Trailliaedoxa within Rubiaceae, using sequence data of four plastid markers (ndhF, rbcL, rps16, trnT­F). The present study provides molecular phylogenetic support for positions of these genera in the subfamily Ixoroideae, and reveals the presence of a basal grade of morphologically distinct, monotypic genera (Crossopteryx, Jackiopsis, Scyphiphora, Trailliaedoxa, and Glionnetia, respectively) in the species-rich Vanguerieae alliance. These five genera may represent sole representatives of their respective lineages and therefore may carry unique genetic information. Their conservation status was assessed, applying the criteria set in IUCN Red List Categories. We consider Glionnetia and Jackiopsis Endangered. Scyphiphora is recognized as Near Threatened despite its extensive range and Crossopteryx as Least Concern.

  • Ethnobotany, Phytochemistry and Pharmacology of Mussaenda Species (Rubiaceae)
    Ethnobotanical Leaflets 12: 469-475. 2008. Ethnobotany, Phytochemistry and Pharmacology of Mussaenda Species (Rubiaceae) K.S.Vidyalakshmi,1 Hannah R.Vasanthi,3 G.V.Rajamanickam2 1Department of Chemistry, PRIST University, Thanjavur. 2Centre For Advanced Research In Indian System of Medicine, SASTRA University, Thanjavur, Tamilnadu, India. 3Department of Biochemistry, Sri Ramachandra University, Porur, Chennai, Tamilnadu, India Issued 2 July 2008 Abstract The genus Mussaenda is an important source of medicinal natural products, particularly iridoids, triterpenes and flavonoids. The purpose of this paper is to cover the more recent developments in the ethnobotany, pharmacology and phytochemistry of this genus. The species in which the largest number of compounds has been identified is Mussaenda pubescens. Pharmacological studies have also been made, however, of other species in this genus. These lesser known plants of the genus are described here according to their cytotoxicity, anti-inflammatory, antiviral, antioxidant and antibacterial properties. The information given here is intended to serve as a reference tool for practitioners in the fields of ethnopharmacology and natural products chemistry. Key words: Mussaenda; Rubiaceae; Mussaein; antifertility. Introduction One way in which the study of medicinal plants has progressed is in the discovery of bioactive compounds from new promising drug species. In this respect, the genus Mussaenda has been important in providing us with several natural products of interest to workers in the field of pharmacology. The species of this genus have the further advantage of being easy to grow. They are pest and disease free and can withstand heavy pruning. Very few species have been explored for chemical and biological studies.

  • The Plant Taxa of H.N. Ridley, 5. the Gentianales
    Gardens' Bulletin Singapore 70 (2): 307–395. 2018 307 doi: 10.26492/gbs70(2).2018-08 The plant taxa of H.N. Ridley, 5. The Gentianales I.M. Turner1, 2, Y.W. Low2, M. Rodda2, K.M. Wong2 & D.J. Middleton2 1Singapore Botanical Liaison Officer, Royal Botanic Gardens Kew, Richmond, Surrey TW9 3AE, U.K. [email protected] 2Singapore Botanic Gardens, National Parks Board, 1 Cluny Road, 259569, Singapore ABSTRACT. Henry Nicholas Ridley (1855–1956) described more than 450 taxa of Gentianales, mostly from Southeast Asia, and was the author of over 70 additional combinations in this order. A listing of these names with place of publication and the types of the Ridley basionyms is given here. Many names are lectotypified. The new combinations Chassalia pauciflora (Ridl.) I.M.Turner and Chassalia violascens (Ridl.) I.M.Turner are proposed for Cephaelis pauciflora Ridl. and Gartnera violascens Ridl. respecitively. Three names are newly reduced to synonymy: Cephaelis elongata Ridl. to Chassalia bracteata Ridl., Geophila matthewii Ridl. to Mussaenda uniflora Wall. ex G.Don and Psychotria setistipula Ridl. to Ixora patens Ridl. Keywords. Apocynaceae, Gentianaceae, lectotype, Loganiaceae, Rubiaceae, typification Introduction This paper continues an intermittent series on the plant taxa named by Henry Nicholas Ridley (1855–1956). Earlier parts have covered the pteridophytes (Turner & Chin, 1998a), gymnosperms (Turner & Chin, 1998b), Zingiberales (Turner, 2000) and basal angiosperms (Austrobaileyales, Canellales, Chloranthales, Laurales, Magnoliales, Nymphaeales and Piperales) (Turner, 2012). In this installment focus shifts to the Gentianales. Ridley described many plant species, particularly from Southeast Asia. He documented the botanical diversity of the region tirelessly and seemed prepared to tackle all and any taxonomic group of vascular plants that came his way.

  • Ecological Flexibility and Conservation of Fleurette's Sportive Lemur
    Ecological flexibility and conservation of Fleurette’s sportive lemur, Lepilemur fleuretae, in the lowland rainforest of Ampasy, Tsitongambarika Protected Area By Marco Campera Oxford Brookes University Thesis submitted in partial fulfilment of the requirements of the award of Doctor of Philosophy May 2018 i Abstract Ecological flexibility entails an expansion of niche breadth in response to different environmental conditions. Sportive lemurs Lepilemur spp. are known to minimise energetic costs via short distances travelled, small home ranges, increased resting time, and low metabolic rates. Very little information, however, is available in the eastern rainforest, the habitat where this genus has its highest diversity. I investigate whether L. fleuretae inhabiting Tsitongambarika (TGK), the southernmost lowland rainforest in Madagascar, shows similar behavioural and ecological adaptations to the sportive lemurs inhabiting dry and deciduous forests. I collected data from July 2015 to July 2016 at Ampasy, northernmost portion of TGK. To understand patterns of resource availability, I collected phenological data on 200 tree species. I explored the ecology of L. fleuretae by gathering data on its diet, ranging patterns, and by reconstructing the activity profiles via a novel method, the unsupervised learning algorithm on accelerometer data. I estimated the anthropogenic pressure in the area and I evaluated whether local management and researchers’ presence had an effect in decreasing it. Lepilemur fleuretae at Ampasy is hyperactive when compared to other species of this genus, with longer distances travelled, larger home ranges, and less time spent resting. The species seems to reduce the competition with the folivorous A. meridionalis by including a higher proportion of fruits and flowers in their diet than other sportive lemurs.
