PhytoKeys 23: 1–17. doi: 10.3897/phytokeys.23.4752 Abstract A checklist of the flora of Chad has been compiled by the authors, based on literature, on-line data-bases, herbarium collections and land surveys (1998-2011). It counts 2,460 records, i.e. 2,288 species (including 128 autonyms), 83 subspecies, 81 varieties, 8 forms, while all the previous available information reported 1,600 species. They belong to 151 Families, with 48.7% of the taxa belonging to the 6 largest families, i.e. Poaceae (14.6%), Fabaceae (13.6%), Cyperaceae (7.0%), Asteraceae (6.2 %), Malvaceae (3.9%) and Rubiaceae (3.4%). A total number or 2,173 species (88.3%) are native to Chad, including 55 (2.2%) endemic species, while 274 (11.0%) are alien to Chad, and 13 (0.5%) are considered cryptogenic, i.e. of uncertain status. It represents a considerable update on previous knowledge on the alien flora of Chad that counted for 131 taxa (5.3%). -

Despite their low species numbers, hornworts represent a key group for understanding the evolution of plant form because the best–sampled current phylogenies place them as sister to the tracheophytes. Despite their low taxonomic diversity, the group has not been monographed worldwide. There are few well-documented hornwort floras for temperate or tropical areas. Moreover, no species level phylogenies or population studies are available for hornworts. Here we aim at filling some important gaps in hornwort biology and biodiversity. We provide estimates of hornwort species richness worldwide, identifying centers of diversity. We also present two examples of the impact of recent work in elucidating the composition and circumscription of the genera Megaceros and Nothoceros. -
Invasive Alien Plants an Ecological Appraisal for the Indian Subcontinent
Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent EDITED BY I.R. BHATT, J.S. SINGH, S.P. SINGH, R.S. TRIPATHI AND R.K. KOHL! 019eas Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent FSC ...wesc.org MIX Paper from responsible sources `FSC C013604 CABI INVASIVE SPECIES SERIES Invasive species are plants, animals or microorganisms not native to an ecosystem, whose introduction has threatened biodiversity, food security, health or economic development. Many ecosystems are affected by invasive species and they pose one of the biggest threats to biodiversity worldwide. Globalization through increased trade, transport, travel and tour- ism will inevitably increase the intentional or accidental introduction of organisms to new environments, and it is widely predicted that climate change will further increase the threat posed by invasive species. To help control and mitigate the effects of invasive species, scien- tists need access to information that not only provides an overview of and background to the field, but also keeps them up to date with the latest research findings. This series addresses all topics relating to invasive species, including biosecurity surveil- lance, mapping and modelling, economics of invasive species and species interactions in plant invasions. Aimed at researchers, upper-level students and policy makers, titles in the series provide international coverage of topics related to invasive species, including both a synthesis of facts and discussions of future research perspectives and possible solutions.

ABSTRACT: Timber has always played an influencing role in human lives. The quality of timber and its behavior in response to fire depends on many parameters. As a result Hymenocardiaacida wood was studied in terms of thermal, chemical, physical and variable techniques. The results obtained were as follows: afterglow time 58.33sec, flame duration 271.67sec, flame propagation rate 4.4x10 -2cm.s -1, ignition time 3.67sec, thermal conductivity14.37 x 10 2Umoh/cm, electrical conductivity 4.4x10 -3Sm -1, ash content 0.95%, moisture content 12.67%, oven dry density 78.7x10 -2g.cm -3, water imbibitions (at different time intervals: 30mins 11.1%, 5hrs 13.8% and 24hrs 22.3%), etc, These results showed it to be a good timber suitable for various construction purposes. Phytochemical screening showed the presence of saponins, tannins, steroids, flavonoids, carbohydrates, proteins, resins, terpenoids, glycosides and alkaloids. The Atomic Absorption Spectrophotometer (AAS) of the sample showed the presence of some metals such as Na, K, Pb, Ca, As, Zn, Mg, and Cu in the decreasing order of their concentrations. -

Recently, based on molecular data, classification of Apocynaceae has undergone considerable revisions. According to the Angiosperm Phylogeny Group III (APGIII, 2009), and the update of the Angiosperm Phylogeny Group APG (APGIV, 2016) the family Asclepiadaceae is now included in the Apocynaceae. The family, as currently recognized, includes some 1500 species divided in about 424 genera and five subfamilies: Apocynoideae, Rauvolfioideae, Asclepiadoideae, Periplocoideae, and Secamonoideae. In this research selected species from the previous families Asclepiadaceae and Apocynaceae were morphologically investigated in an attempt to distinguish morphological important characters supporting their new molecular classification. 40 morphological characters were treated as variables and analyzed for cluster of average linkage between groups using the statistical package SPSS 16.0.

Supplementary Figure 1(a) visualizes Mass2Motif-mapped molecular family C. Three Mass2Motifs 86, 130, and 149 were extracted from MS/MS spectra in C; these Mass2Motifs explained MS/MS features which are commonly observed in plant metabolomics dataset, so they could be easily annotated. Mass2Motif 130 was annotated as a kaempferol- related motif, while Mass2motif 86 as a quercetin-related motif. Mass2Motif 149 contained MS/MS fragments which are commonly observed in collision-induced dissociation (CID) fragmentation spectra of flavonol aglycones, such as quercetin or myricetin (Fabre et al., 2001). -
Tylophora Indica Are Used for the Treatment Of
P S. Jakhi Family Asclepiadaceae is commonly known as milk weed family, is a former plant family which is now treated as a subfamily (subfamily Asclepiadaideae) in the family Apocynaceae (Bruyns 2000, APG IV). They form a group of perennial herbs twining shrubs, rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the genus Asclepias (milkweeds). Calotropis, Asclepias, Stapelia, Tylophora are the sole members of the family. P . S. Jakhi The family comprises of about 175 genera and 2,200 species all over the world, distributed in tropical and subtropical regions . In India the family Asclepiadaceae is represented by about 53 genera and about 250 species. P S. Jakhi The members of Asclepiadaceae family are mostly herbs (Asclepias) or sometimes shrubs (Calotropis procera) or woody climbers (Tylophora, Ceropegia), rarely small trees (Calotropis gignata) ,with milky sap or often cactus like habit (Stapelia). P S. Jakhi Calotropis procera P S. Jakhi Stem The stem of a plant contain milky juice present in long branching laticiferous tubes. Stem is erect (Calotropis) or twining (Bidaria), branched, herbaioud or woody, solid, cylindrical or angular with milky sap, rarely hairy (Calotropis). The vascular bundles in the stems are generally bicollateral . Stem of Calotropis procera P S. Jakhi LEAF:- The leaves are mostly opposite decussate (Calotropis), rarely alternate or whorled, simple, petiolate or subsessile, exstipulate, entire at margins,generally waxy on both surface (Calotropis). In xerophytic secies such as Stapelia, the leaves are reduced to scales or spines, the leaves of Asclepias curassavica are petiolate,whereas they are semi-amplexicaul in Calotropis procera, The petiole is pulvinous in Calotropis procera Cryptostagia grandiflora . -

We established permanent plots to characterize plant diversity, above-ground biomass, and vegetation Flora patterns in a tropical dry forest in Kimbi-Fungom National Park, Cameroon. Our results contribute to long-term Environmental assessment monitoring, predictions, and management of dry forest ecosystems, which are often vulnerable to anthropogenic Environmental health pressures. Environmental impact assessment Dry forest Background and objectives: Considerable consensus exists regarding the importance of dry forests in species di- Bamenda highlands versity and carbon storage; however, the relationship between dry forest tree species composition, species rich- Kimbi-Fungom National Park ness, and carbon stock is not well established. Also, simple baseline data on plant diversity are scarce for many dry Carbon forest ecosystems. This study seeks to characterize floristic diversity, vegetation patterns, and tree diversity in Semi-deciduous permanent plots in a tropical dry forest in Northwestern Cameroon (Kimbi-Fungom National Park) for the first Tree composition time.
