A New Species of Brachystelma (Apocynaceae)
A new species of Brachystelma (Apocynaceae) from Iringa and Dodoma Regions, Tanzania Ralph G Peckover A new species, Brachystelma tanzaniensis is described from Tanzania. Photographs by the author except where otherwise indicated. Introduction large multi-flowered related species including Brachystelma is a genus of around 100 currently B. barberae and B. buchananii. recognised species. The group is confined mostly to Members of Brachystelma are characterised by leaves southern Africa with around two thirds of all species, that are opposite, linear to elongated, with wavy, with the rest in Africa and also in India, and a single sinuate to entire straight margins. These are bright species in Australia. All the species have a swollen green to greyish and glabrous to very hairy. The underground caudex or fusiform roots. The stems are flowers are borne in the axils of the leaves or terminal deciduous and die back at the end of the growing in panicles. Each flower has five corolla lobes which season. In this article a new species of Brachystelma is can be united at their tips or free. The corona contains described from Tanzania, namely B. tanzaniensis.

It is grown as a rain fed crop throughout the tropics and subtropics. It is a short-day plant but also grows well in long-day areas. The crop thrives best on moderately fertile, well-drained soils with a pH ranging from 5.5SAMPLE to 8.0 and is sensitive to salinity. CHAPTERS Sesame is cultivated both by smallholders and at larger industrial scales. Sesame propagation is by broadcasting or seed drilling in rows. Broadcasting seeds is the most common seeding method used by smallholder farmers. The seeds are often mixed with sand, soil or ash and then broadcast or drilled by hand in small furrows. -

Impact of Ethnobotanical Utilization on the Population Structure of Androstachys Johnsonii Prain
Bakali et al. Insights For Res 2017, 1(1):50-56 DOI: 10.36959/948/461 | Volume 1 | Issue 1 Insights of Forest Research Research Article Open Access Impact of Ethnobotanical Utilization on the Population Structure of Androstachys Johnsonii Prain. in the Vhembe Area of the Limpopo Province, South Africa Bakali M1, Ligavha-Mbelengwa MH1, Potgieter MJ2 and Tshisikhawe MP1* 1Department of Botany, University of Venda, South Africa 2Department of Biodiversity, University of Limpopo, Sovenga, South Africa Abstract Due to high levels of impoverishment, rural communities in southern African are highly dependent on their surroundings to sustain their livelihood. However, the rampant harvesting of Androstachys johnsonii Prain. In Vhembe area is a cause for concern although its conservation status is of Least Concern. Androstachys johnsonii is a tree species used for a variety of purposes in the Vhembe Area of South Africa to maintain households. Thus in order to obtain baseline data to propose ways of preserving the species, an investigation was launched to determine the extent of usage of A. johnsonii at Matshena village and document its population structure via stem size classes, crown health and plant height classes. Results indicate that this tree species is being used for a variety of purposes by inhabitants, with 65% of trees surveyed showing signs of harvesting. Due to its extremely durable hardwood this species is mostly used for fencing, roofing, pillar construction, and as firewood. Additional ethnobotanical uses include fodder for goats and cattle and medicinal purposes. Of the 353 A. john- sonii trees measured, the majority (27%) are in the 0-10 cm stem size class, and nearly 88% are lower than 5 m in height. -
Species Accounts
Species accounts The list of species that follows is a synthesis of all the botanical knowledge currently available on the Nyika Plateau flora. It does not claim to be the final word in taxonomic opinion for every plant group, but will provide a sound basis for future work by botanists, phytogeographers, and reserve managers. It should also serve as a comprehensive plant guide for interested visitors to the two Nyika National Parks. By far the largest body of information was obtained from the following nine publications: • Flora zambesiaca (current ed. G. Pope, 1960 to present) • Flora of Tropical East Africa (current ed. H. Beentje, 1952 to present) • Plants collected by the Vernay Nyasaland Expedition of 1946 (Brenan & collaborators 1953, 1954) • Wye College 1972 Malawi Project Final Report (Brummitt 1973) • Resource inventory and management plan for the Nyika National Park (Mill 1979) • The forest vegetation of the Nyika Plateau: ecological and phenological studies (Dowsett-Lemaire 1985) • Biosearch Nyika Expedition 1997 report (Patel 1999) • Biosearch Nyika Expedition 2001 report (Patel & Overton 2002) • Evergreen forest flora of Malawi (White, Dowsett-Lemaire & Chapman 2001) We also consulted numerous papers dealing with specific families or genera and, finally, included the collections made during the SABONET Nyika Expedition. In addition, botanists from K and PRE provided valuable input in particular plant groups. Much of the descriptive material is taken directly from one or more of the works listed above, including information regarding habitat and distribution. A single illustration accompanies each genus; two illustrations are sometimes included in large genera with a wide morphological variance (for example, Lobelia). -

Aloe Scientific Primer International Aloe Science Council
The International Aloe Science Council Presents an Aloe Scientific Primer International Aloe Science Council Commonly Traded Aloe Species The plant Aloe spp. has long been utilized in a variety of ways throughout history, which has been well documented elsewhere and need not be recounted in detail here, particularly as the purpose of this document is to discuss current and commonly traded aloe species. Aloe, in its various species, can presently and in the recent past be found in use as a decorative element in homes and gardens, in the creation of pharmaceuticals, in wound care products such as burn ointment, sunburn protectant and similar applications, in cosmetics, and as a food, dietary supplements and other health and nutrition related items. Recently, various species of the plant have even been used to weave into clothing and in mattresses. Those species of Aloe commonly used in commerce today can be divided into three primary categories: those used primarily in the production of crude drugs, those used primarily for decorative purposes, and those used in health, nutritional and related products. For reference purposes, this paper will outline the primary species and their uses, but will focus on the species most widely used in commerce for health, nutritional, cosmetic and supplement products, such as aloe vera. Components of aloe vera currently used in commerce The Aloe plant, and in particular aloe vera, has three distinct raw material components that are processed and found in manufactured goods: leaf juice; inner leaf juice; and aloe latex. A great deal of confusion regarding the terminology of this botanical and its components has been identified, mostly because of a lack of clear definitions, marketing, and other factors. -
