The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

Reproductive Biology of Aloe Peglerae
THE REPRODUCTIVE BIOLOGY AND HABITAT REQUIREMENTS OF ALOE PEGLERAE, A MONTANE ENDEMIC ALOE OF THE MAGALIESBERG MOUNTAIN RANGE, SOUTH AFRICA Gina Arena 0606757V A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, in fulfillment of the requirements for the degree of Master of Science Johannesburg, South Africa June 2013 DECLARATION I declare that this Dissertation is my own, unaided work. It is being submitted for the Degree of Master of Science at the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination at any other University. Gina Arena 21 day of June 2013 Supervisors Prof. C.T. Symes Prof. E.T.F. Witkowski i ABSTRACT In this study I investigated the reproductive biology and pollination ecology of Aloe peglerae, an endangered endemic succulent species of the Magaliesberg Mountain Range in South Africa. The aim was to determine the pollination system of A. peglerae, the effects of flowering plant density on plant reproduction and the suitable microhabitat conditions for this species. Aloe peglerae possesses floral traits that typically conform to the bird-pollination syndrome. Pollinator exclusion experiments showed that reproduction is enhanced by opportunistic avian nectar-feeders, mainly the Cape Rock-Thrush (Monticola rupestris) and the Dark- capped Bulbul (Pycnonotus tricolor). Insect pollinators did not contribute significantly to reproductive output. Small-mammals were observed visiting flowers at night, however, the importance of these visitors as pollinators was not quantified in this study. Interannual variation in flowering patterns dictated annual flowering plant densities in the population. The first flowering season represented a typical mass flowering event resulting in high seed production, followed by a second low flowering year of low seed production. -
Pogonia Subalpina (Orchidaceae): a New Species from Japan
Bull. Natl. Mus. Nat. Sci., Ser. B, 43(3), pp. 79–86, August 22, 2017 Pogonia subalpina (Orchidaceae): a new species from Japan Tomohisa Yukawa* and Yumi Yamashita Tsukuba Botanical Garden, National Museum of Nature and Science, Amakubo 4–1–1, Tsukuba, Ibaraki 305–0005, Japan *E-mail: [email protected] (Received 11 May 2017; accepted 28 June 2017) Abstract Pogonia subalpina T. Yukawa & Y. Yamashita (Orchidaceae) is newly described from marshy, subalpine grasslands of central and northern parts in Honshu, Japan. This species is simi- lar to Pogonia japonica Rchb. f. and P. minor (Makino) Makino, but can be distinguished in flower by its short hairy crests on the disk of the labellum mid-lobe, by its glabrous abaxial surface of the labellum, and by its single, broad, purplish pink band along the mid-vein of the petals. Nucleotide sequence divergences among the three entities in the nuclear ribosomal DNA ITS and the plastid trnK 5’ intron regions warrant independent species status of the new entity. Key words : Japan, new species, Orchidaceae, Pogonia, taxonomy. Introduction ica and P. minor has been generally recognised (Yukawa, 2015).

Thesis Outline
CHAPTER 3 Nectary structure and nectar presentation in Aloe castanea and A. greatheadii var davyana (Asphodelaceae) M. Nepi1, H. Human2, S.W. Nicolson2, L. Cresti1, E. Pacini1 1 Department of Environmental Sciences “G. Sarfatti”, University of Siena, Via Mattioli 4, 53100 Siena, Italy 2Department of Zoology and Entomology, University of Pretoria, Pretoria 0002, South Africa Paper published in Plant Systematics and Evolution 257: 45-55 (2006) 59 Abstract This paper deals with the nectary structure and nectar presentation of two species belonging to different sections of the genus Aloe: A. castanea (Anguialoe) and A. greatheadii var davyana (Pictae). The development of the nectary was studied by means of bright field and fluorescence light microscopy and scanning electron microscopy (SEM) in three flower stages (young, intermediate, old). Both species have septal nectaries. In A. castanea, a subsidiary tissue, not present in A. greatheadii var davyana, was found beneath the nectary epithelium. This tissue accumulated starch that was hydrolyzed during secretion. Starch was slightly accumulated around the nectary in A. greatheadii var davyana. The distribution of chlorophyll in the ovary was also different in the two species. These anatomical differences are not, however, correlated with greater nectar production in A. castanea. In this species, the nectary seems to degenerate after secretion, while in A. greatheadii var davyana no sign of degeneration was observed. Differences in nectar presentation among the two species may account for different pollinators visiting their flowers. 60 Introduction Fahn (1979) presented a topographical classification of floral nectaries, indicating nine different types. Among them, the “ovarial nectary” type includes nectaries that are placed in the septal region between adjacent carpels, the so-called septal nectaries or gynopleural nectaries as they have been more recently defined by Smets and Cresens (1988). -

Its identity was confirmed by morphological comparison and DNA extractions from herbarium specimens collected between 1914 and 1938. Results from the molecular phylogenetic analyses demonstrated that L. hostifolia belongs to the L. makinoana complex. In comparison with other members of the L. makinoana complex, the broadly ovate labellum, short dormancy period, and flowering from November to March are unique characteristics of L. hostifolia. Results from the molecular phylogenetic analyses also suggested that L. hostifolia has had a long-isolated history in the Bonin Archipelago and probably migrated from temperate East Asia. -

Antioxidant, Antifungal, Antibiofilm, and Cytotoxic Activities of Mentha
medicines Review Antioxidant, Antifungal, Antibiofilm, and Cytotoxic Activities of Mentha spp. Essential Oils Annarita Stringaro 1, Marisa Colone 1 and Letizia Angiolella 2,* 1 National Center for Drug Research and Evaluation, Italian National Institute of Health, Viale Regina Elena, 299, 00161 Rome, Italy; [email protected] (A.S.); [email protected] (M.C.) 2 Department of Public Health and Infectious Diseases, Sapienza University of Rome, P.le Aldo Moro, 5, 00185 Rome, Italy * Correspondence: [email protected]; Tel.: +39-06-4468-225 Received: 23 July 2018; Accepted: 15 October 2018; Published: 21 October 2018 Abstract: Since ancient times, plants have been used to preserve food, or for their health properties. Essential oils are complex mixtures of volatile compounds that are obtained from botanical material, specifically from aromatic plants. Lamiaceae is one of the most important families in the production of essential oils, as it has both antioxidant and antimicrobial properties. The essential oils of Mentha (the Lamiaceae family) have been extensively studied for their biological actions. In this review, we report the antioxidant, antifungal, antibiofilm, and cytotoxic properties of Mentha spp. essential oils. The first objective is to provide comprehensive information about the use of essential oils in the treatment of fungal infections, or as antioxidants and integrative anticancer therapy. The second is to explore the evidence supporting its effectiveness in treating diseases without causing any serious adverse reactions. Keywords: essential oil; Mentha spp.; antioxidant; antifungal; antibiofilm; toxicity 1. Introduction Plant essential oils (EOs) are produced predominantly using steam distillation, but can also be generated using fermentation, crushing, extraction, hydrolysis, and airing [1].
