El-Naggar*** *Biology Department, Faculty of science, Sana, a Uuiversity, Yemen **Biology Department, Faculty of Education, Aden Uuiversity, Yemen ***Botany Department , Faculty of science, Assiut Uuiversity, Egypt ABSTRACT: Toor Al-Baha of Lahej governorate (Yemen) lies between latitudes 12° 58` - 13° 20` N, and longitudes 44° 11` - 44° 39`E, has been studied floristically. This region covers about 1883 sq km. Analysis of the floristic composion of the studied area have been carried out and proved that, about 560 taxa belong to 288 genera and 89 families of the vascular plants have been recorded. Of these, the largest families are: Poaceae, Asteraceae, Asclepiadaceae, Euphorbiaceae, Fabaceae, Acanthaceae, Capparaceae, Lamiaceae, Boraginaceae, Malvaceae, Solanaceae, Mimosaceae, Tiliaceae, Amaranthaceae, Cucurbitaceae, Convolvulaceae and Scrophulariaceae, while the largest genera are: Euphorbia, Acacia, Grewia, Heliotropium, Indigofera, Barleria, Eragrostis, Aloe, Hibiscus, Solanum, Tephrosia, Cadaba, Crenulluma, Ficus, Justicia, and Senna. It was also noted that the generic index = 1.94. Sixty eight succulents taxa belong to eighteen families were recorded in the flora of the studied area, among these families six are the richest ones: Asclepiadaceae, Euphorbiaceae, Aloaceae, Aizoaceae, Crassulaceae and Vitaceae. Twenty eight taxa are endemic to flora of Yemen, among them Rhytidocaulon splendidum T. A. McCoy is endemic to Toor Al-Baha only. Another thirty four taxa are found to be near endemic to the flora of Yemen. INTRODUCTION: the south, Sultanate of Oman in the east, and the Red Sea in the west (Fig. 1).

    Origin of Plant Originated from Some Had Possibly Changed Recognise Original Wild Species. Suggested a Relationship with Pr

    The possible origin of Cucumis anguria L. by A.D.J. Meeuse (National Herbarium, Pretoria) (Issued Oct. 2nd, 1958) Cucumis India Gherkin” “Bur anguria L., the “West or Gherkin”, is a cultigen known to have occurred in the West Indies in a cultivated or more or less adventitious state since before 1650 when the first accounts of this plant were published (1, 2). The occurrence of a single species of this old world genus — which is mainly African but extends through South West Asia to India — in America, combined with the fact that it is almost exclusively found in cultivation or as an escape, makes one feel suspicious about its being truly indigenous in the New World. Naudin (4) discussed the history of this plant and suggested that it introduced from West Africa whence slaves were was originally negro brought to the New World. However, he admittedly did not know any wild African species of Cucumis which resembles C. anguria sufficiently to deserve consideration as its probable ancestor. J. D. Hooker (5) also discussed the origin of the West Indian plant and was inclined to agree that it originated from some wild African ancestral form which had possibly changed so much through cultivation that it would be somewhat difficult to recognise the original wild species. He suggested a relationship with Cucumis prophetarum and “C. figarei” but he cautiously stated that these two species are perennial, whereas C. anguria is a typical annual. A. de Candolle (6) pointed out that although C. anguria was generally assumed to be a native of the Antilles, more particularly of Jamaica, two facts plead against this idea.

Read Full License Page 1/21 Abstract Background This is the rst study on seed germination of Cucumis prophetarum in the Arabian Peninsula. Light and temperature as the main environmental factors and seed storage conditions greatly affect the germination of many Cucurbitaceae species. C. prophetarum is the perennial prostrate with woody rootstocks that grow throughout the year in the arid Arabian deserts. We examined the effects of seed storage conditions and sterilization by sodium hypochlorite (NaOCL) on germination of C. prophetarum seeds. Matured, fresh and eld stored seeds were collected in March of 2016 and 2017 from a population in the United Arab Emirates. Fresh and the stored seeds (eld, freeze, and room temperature) were germinated at three temperature regimes (15/25, 20/30 and 25/35°C) in both continuous darkness and alternating 12 h light/12 h darkness. Results The fresh and freeze stored seeds had higher germination percentage than the eld and room temperature stored seeds.

Author for correspondence: Judith X. Becerra, [email protected] Abstract Bursera is one of the most diverse and abundant groups of trees and shrubs of the Mexican tropical dry forests. Its interaction with its specialist herbivores in the chrysomelid genus Blepharida, is one of the best-studied coevolutionary systems. Prior studies based on molecular phylogenies concluded that Bursera is a monophyletic genus. Recently, however, other molecular analyses have suggested that the genus might be paraphyletic, with the closely related Commiphora, nested within Bursera. If this is correct, then interpretations of coevolution results would have to be revised. Whether Bursera is or is not monophyletic also has implications for the age of Burseraceae, since previous dates were based on calibrations using Bursera fossils assuming that Bursera was paraphyletic. We performed a phylogenetic analysis of 76 species and varieties of Bursera, 51 species of Commiphora, and 13 outgroups using nuclear DNA data. We also reconstructed a phylogeny of the Burseraceae using 59 members of the family, 9 outgroups and nuclear and chloroplast sequence data. These analyses strongly confirm previous conclusions that this genus is monophyletic.

    ON THE DRY SIDE OCTOBER 2018 CENTRAL COAST CACTUS & SUCCULENT SOCIETY OCTOBER SPEAKER OF THE MONTH: GENE SCHROEDER Ferocactus: The Fantastic Barrel Cacti of the Southwest & Mexico During General Kearney’s 1846 Mexican-American War expedition to Santa Fe and the later conquest of California, Lt. Emory, an officer in his force, collected and sketched several large cacti. In 1849, now Major Emory, became director of the Mexican-American Boundary Survey tasked with making a compre- hensive survey of the natural history of this newly acquired region. Large collections of cacti were made and sent to Dr. George Engelmann who later published several papers including the 1859 “Cactaceae of the Boundary.” All were amazed by the giant barrel cacti of the new territories. They were as striking and unusual then as now. For his work, Engelmann drew from botanists and explorers of these expeditions and surveys as well as professional colleagues of that era. Their names are commemorated in current species names within the genera Ferocactus erected by Britton & Rose as part of their classic 1922 work “The Cactaceae.” Big, up to 4 feet or more in height, protected by fierce thorns, topped with large flowers and edible fruit they earned the awe and respect of all who saw them. Native usage as emergency water sources and cattle food earned them the nickname, ‘traveler’s friend.’ Ranging across approximately 30 species, they now can be found in most botanic gardens and a growing number of xeric landscapes where their size and presence make them landmark plants that are tough, long lived and generally easy to grow.

We report chromosome counts for ten taxa of Vincetoxicum sensu stricto (s. str.) (Apocynaceae) from Turkey (of which two are endemic), including the first chromosome counts for V. canescens subsp. pedunculata, V. funebre, V. fuscatum subsp. boissieri, V. parviflorum and V. tmoleum. Two taxa of V. fuscatum proved to be tetraploid (2n=44) and the remaining eight taxa diploid (2n=22). Molecular phylogenetic analyses based on nrDNA (ITS) and cpDNA (trnT-trnL) (including 31 newly generated sequences) confirm the position of the TurkishVincetoxicum in the Vincetoxicum s. str. clade. Vincetoxicum fuscatum, V. parviflorum, V. speciosum, as well as the Turkish endemic V. fuscatum subsp. boissieri, were clearly resolved as species-level clades, whereas the delimitation of the rest of the Turkish taxa was less clear based on molecular data.

INTRODUCTION In 1962 Bally described Rhvtidoeaulon to accommodate two species with very distinc- tive vegetative parts and small, but structurally rather different flowers. These had been discovered in Ethiopia and Somalia in 1955 and 1944 respectively. The first collection of a Rhxtidocaulon that I have been able to locate was made in Somaliland on 27 November 1894 by A. Donaldson Smith (# 278 (BM)). This plant lacks flowers, so that it cannot be assigned to any of the known species, but the stem indicates that it clearly belongs to Rhytidocaulon. In 1897 Theodore Bent sent a plant to Kew which flowered on 13 September of that year. N.E. Brown noted that the stems were 'remarkably rugulose from irregular furrows' and he later described it as Carallwna torta. Leach (1970) thought that it was probably a Ceropegia and it was only in 1990 that Gilbert moved it to Rhytidocaulon, where it clearly belongs. Since Bally's description, several species have been added so that there are now eight names (including Caralluma torta) in Rhytidocaulon. Plants have rarely been collected and consequently few herbarium records exist so that it is very difficult to assess the true variability of the species or plot their distributions accurately.

    ii Quick Guide This book is divided into two sections: the first part provides descriptions of some common trees and shrubs of Botswana, and the second is the complete checklist. The scientific names of the families, genera, and species are arranged alphabetically. Vernacular names are also arranged alphabetically, starting with Setswana and followed by English. Setswana names are separated by a semi-colon from English names. A glossary at the end of the book defines botanical terms used in the text. Species that are listed in the Red Data List for Botswana are indicated by an ® preceding the name. The letters N, SW, and SE indicate the distribution of the species within Botswana according to the Flora zambesiaca geographical regions. Flora zambesiaca regions used in the checklist.
