Philenoptera Violacea | Plantz Africa About:Reader?Url= Philenoptera violacea | Plantz Africa about:reader?url=http://pza.sanbi.org/philenoptera-violacea pza.sanbi.org Philenoptera violacea | Plantz Africa Introduction The wood of this attractive, hard, frost-sensitive "rain-tree" makes a stunning ornamental display. Description Description Philenoptera violacea is a medium- to large-sized, deciduous to semi-deciduous tree up to 15 m tall with a wide-spreading, dense and rounded crown. The main stem is tall, straight and bare, occasionally bent and twisted. The bark is grey and flaking on older branches and stem, but smooth, light grey and covered with dense hairs on younger branches, exuding a sticky red sap when cut. 1 of 5 2016/12/15 12:19 PM Philenoptera violacea | Plantz Africa about:reader?url=http://pza.sanbi.org/philenoptera-violacea Leaves are large (70-200 mm long), unevenly compound with 1-3 pairs of opposite leaflets and one terminal leaflet, hard and rough in texture, shiny or glossy above and grey-green beneath, with prominent midribs. The terminal leaflets are always much bigger than the lower leaflets (about 180 mm long and 90 mm broad). Flowers are scattered, usually borne in dense terminal sprays 120-300 mm long at the tips of the branches, varying in colour from white and pink to bluish-pink, mauve or deep violet, and are sweet- scented. They appear from September to December, before or together with the new leaves. Fruit is a flat pod, non-splitting, relatively large (about 120 x 25 mm), hairless, tapering at both ends, persisting on the tree during winter, usually 2- or 3-seeded. The seeds are kidney-shaped, reddish, and compressed. 2 of 5 2016/12/15 12:19 PM Philenoptera violacea | Plantz Africa about:reader?url=http://pza.sanbi.org/philenoptera-violacea Conservation Status Status Philenoptera violacea is a protected tree in South Africa. Distribution and habitat Distribution description Philenoptera is a small genus of 12 species, found in Madagascar, and tropical and southern Africa. Seven of these species occur in southern tropical Africa and southern Africa. South Africa is home to three species of Philenoptera, which are found in four provinces of the country, namely Limpopo, Mpumalanga, KwaZulu-Natal and Eastern Cape. Philenoptera violacea is distributed in three provinces of South Africa: Limpopo, Mpumalanga and KwaZulu-Natal. In Limpopo it is found in the northern part of the province. In Mpumalanga it occurs in the warmer, almost frost-free parts of the Lowveld and the northern bushveld regions, and in KwaZulu-Natal it is distributed in the northern part of the province. Derivation of name and historical aspects History The name Philenoptera is derived from the Greek words philenos (tractable or manageable) and pteros (wing) which conveys the meaning that the wing makes the pod manageable for dispersal. Violacea is derived from the Latin word violaceus (violet) which refers to the violet (blue-red) flowers of the apple-leaf tree. Ecology Ecology Philenoptera violacea is a frost-sensitive and drought-resistant species. The tree is frequently attacked by the spittle bug or frog-hopper, which causes exudation of water from stem and branches to such an extent that the ground or area covered by this plant is wet, allowing it to use the moisture in drought conditions. It occurs at low altitudes, from 50-1250 m, in drier areas, mostly on sandy or alluvial soils. Plants are usually found in bushveld, open wooded grassland, on the banks of seasonal streams, near water courses and on floodplains. Uses Use 3 of 5 2016/12/15 12:19 PM Philenoptera violacea | Plantz Africa about:reader?url=http://pza.sanbi.org/philenoptera-violacea Philenoptera violacea has economic value as the wood is used to make good, attractive household articles such as grinding blocks and tool handles. Generally the wood is commercialised in making carvings, grain mortars, building poles and mealie stampers. In African tradition, it is also used to make dug-out canoes. The leaves of the apple-leaf tree provide forage for giraffes, and the pods serve as a source of nourishment to these animals. In southern Africa, P. violacea is used in traditional remedies. Most parts of the plant are used to treat diarrhoea. The roots are used for gastro-intestinal problems; powdered root-bark is used to treat colds and snakebite. Root infusions are commonly used as part of a hookworm remedy. Growing Philenoptera violacea Grow The apple-leaf tree is a good garden subject owing to its graceful habit, pale foliage and beautiful flowers. Although it grows slowly, it is an interesting ornate tree which gives a stunning display when in flower. Propagation is by seed. The seeds must first be soaked in hot water, left overnight and planted the next morning in seedling trays. Cover the seeds lightly with river sand and keep moist. Placing a clear glass over the seedling tray can speed up germination. Seeds usually germinate in four to six days after being sown. The plants should be kept in partial shade for three to five weeks before moving them into full sun, and should be planted in scattered clumps in a suitable habitat. The success rate of P. violacea is greater in frost-free areas. The plant is not frost- resistant, but it can survive in colder climates if properly protected during the first two to four years.

  • Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi
    YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work.

Philenoptera violacea (Klotzsch) Schrire and Xanthocercis zambesiaca (Baker) Dumaz-le- Grand plant extracts are traditionally used by South African traditional healers for the treatment of inflammation related disorders; however, their efficacy has not been determined. The aim of this study was to investigate the antimicrobial activity of the mixture of leaves, flower & twig of each plant extract respectively. Antimicrobial activity was determined using p- Iodonitrotetrazolium chloride (INT) assay on gram-positive bacterium: Staphylococcus aureus, S. epidermidis, S. saprohyticus, Bacillus subtilis, and gram-negative bacterium: Enterobacter cloacae, Escherichia coli, Pseudomonas aeruginosa. Results of antimicrobial activity revealed that both plant extracts had no antimicrobial activity against selected micro-organisms. Thus, we couldn’t support or confirm the antimicrobial activity potential of these plants as reported by traditional healers, however, factors that might have contributed to these results were not excluded. Key words: Philenoptera violacea, Xanthocercis zambesiaca, Antimicrobial activity, p-Iodonitrotetrazolium chloride (INT) assay, cancer INTRODUCTION inflammatory response.
