Received: 10 January 2019; Accepted: 22 February 2019; Published: 26 February 2019 Abstract: The lotus (Nelumbo Adans.) is a perennial aquatic plant with important value in horticulture, medicine, food, religion, and culture. It is rich in germplasm and more than 2000 cultivars have been cultivated through hybridization and natural selection. Microsporogenesis and male gametogenesis in the anther are important for hybridization in flowering plants. However, little is known about the cytological events, especially related to the stamen, during the reproduction of the lotus. -
Leaf Epidermal Studies of Three Species of Acalypha Linn
Available online a t www.pelagiaresearchlibrary.com Pelagia Research Library Advances in Applied Science Research, 2012, 3 (5):3185-3199 ISSN: 0976-8610 CODEN (USA): AASRFC Leaf epidermal studies of three species of Acalypha Linn. (Euphorbiaceae) 1* Essiett Uduak Aniesua and 1Etukudo Inyene Silas Department of Botany and Ecological Studies, University of Uyo, Uyo _____________________________________________________________________________________________ ABSTRACT Leaf epidermal studies of three species of Acalypha are described. The mature stomata were laterocytic, staurocytic, anisocytic, paracytic and diacytic. The abnormalities noticed include unopen stomatal pore, two stomata sharing one subsidiary cell, one guard cell, parallel contiguous and aborted guard cell. A. godseffiana can be distinguished by parallel contiguous on both surfaces. Curved uniseriate non-glandular trichomes were restricted to A. wilkesiana. Two stomata sharing one subsidiary cell occurred only on the lower surface of A. hispida. The shapes of epidermal anticlinal cell walls, guard cell areas, stomata index and trichomes varied. The differences are of taxonomic importance and can be used to identify and delimit each species by supporting other systematic lines of evidence. Keywords: Acalypha species, Epidermal, Stomata, Nigeria, Euphorbiaceae. _____________________________________________________________________________________________ INTRODUCTION Euphorbiaceae, the spurge family of the flowering plants with 500 genera and around 7,500 species.

S. M. El Naggar & N. Sawady Pollen Morphology of Malvaceae and its taxonomic significance in Yemen Abstract El Naggar, S. M. & Sawady N.: Pollen Morphology of Malvaceae and its taxonomic signifi- cance in Yemen. — Fl. Medit. 18: 431-439. 2008. — ISSN 1120-4052. The pollen morphology of 20 species of Malvaceae growing in Yemen was investigated by light (LM) and scanning electron microscope (SEM). The studied taxa belong to 9 genera and three different tribes. These taxa are: Abelmoschus esculentus, Hibiscus trionum, H. micranthus, H. deflersii, H. palmatus, H. vitifolius, H. rosa-sinensis, H. ovalifolius, Gossypium hirsutum, Thespesia populnea (L.) Solander ex Correa and Senra incana (Cav.) DC. (Hibiscieae); Malva parviflora and Alcea rosea (Malveae); Abutilon fruticosum, A. figarianum, A. bidentatum, A. pannosum, Sida acuta, S. alba and S. ovata (Abutileae). Pollen shape, size, aperture, exine structure and sculpturing as well as the spine characters proved that they are of high taxonom- ic value. Pollen characters with some other morphological characters are discussed in the light of the recent classification of the family in Yemen. Key words: Malvaceae, Morphology, Yemen. Introduction Malvaceae Juss. (s. str.) is a large family of herbs, shrubs and trees; comprising about 110 genera and 2000 species. It is a globally distributed family with primary concentrations of genera in the tropical and subtropical regions (Hutchinson 1967; Fryxell 1975, 1988 & 1998; Heywood 1993; La Duke & Doeby 1995; Mabberley 1997). Due to the high economic value of many taxa of Malvaceae (Gossypium, Hibiscus, Abelmoschus and Malva), several studies of different perspective have been carried out, such as those are: Edlin (1935), Bates and Blanchard (1970), Krebs (1994a, 1994b), Ray (1995 & 1998), Hosni and Araffa (1999), El Naggar (1996, 2001 & 2004), Pefell & al. -

Hollyhock Rust Caroline Jackson and Josephine Mgbechi-Ezeri
Sample of the week: Hollyhock rust Caroline Jackson and Josephine Mgbechi-Ezeri Have strange orange and brown bumps plagued your flower beds this year? The prolonged cool temperatures and heavy precipitation this spring have allowed fungal pathogens to flourish. Here is one heavy infestation of Hollyhock rust, a disease that is caused by the fungal pathogen Puccinia malvacearum. Common hosts include Alcea rosea, (hollyhock), Abutilon spp. (flowering maple), Malvaceae spp. (rose mallow), Figure 1. Yellow spots on upper leaf surface Photo Credit: and common weed mallow. It is Caroline Jackson, University of Missouri Plant Diagnostic Clinic one of the most common diseases of hollyhock. Symptoms of the disease include the yellow to red spots on upper leaf surface, and brown pustules that appear blister-like occur on lower leaf surface and stem. Leaves that are heavily infected often wilt, turn brown and die. This disease is the most common of hollyhock and can spread rapidly from leaf to leaf. The fungus overwinters in the infected plant materials, and in the spring produce spores that are dispersed by wind to initiate infection on new plants. Figure 2.

Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls). -

Chromosome Numbers in the Polemoniaceae Representatives Of
1937 171 Chromosome Numbers in the Polemoniaceae By Walter S. Flory Division of Horticulture, Texas Agricultural Experiment Station This family is divided by systematists into two subfamilies. Cobaeoideae is composed of the genera Cantua, Huthia, and Cobaea which are tall shrubs, trees, or vines. The approximately fourteen other (herbaceous or low shrubby) genera comprise the subfamily Polemonioideae. From the standpoint of number of included species the most important of these latter genera are Gilia, Phlox, Polemo nium, and Collomia. The genera Phlox and Polemonium are each quite distinct and their species are seldom confused with those of other genera, but the remaining twelve genera of this subfamily apparently do not have taxonomic boundaries of equivalent distinctness. Certain species have been placed in one genus by one author, and in one or more different genera by others. The genus Gilia has been ex tended by some writers to include practically all species of the Polemonioideae outside of the genera Phlox and Polemonium. This was first pointed out to me by Professor Edgar T. Wherry who is making a taxonomic and geographic study of the Polemoniaceae, and was increasingly emphasized as literature sources and herbarium specimens were consulted and examined. It has been the purpose of the work herein presented to secure data on all obtainable polemoniaceous species with respect to chro mosome numbers, size, and general morphology. Especial attention has been given to securing information of significance from a taxono mic standpoint. Since several factors combine to make the immedi ate completion of the original program impossible it seems desirable, meanwhile, to present the accumulated data, together with suggested conclusions.
