CATALOGUE of the GRASSES of CUBA by A. S. Hitchcock
CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. -

Rajapaksha1, C. de Alwis1 1Butterfly Conservation Society of Sri Lanka, 762/A, Yatihena, Malwana, Sri Lanka 2 E-mail: [email protected] Abstract Larval food plants (LFPs) of Sri Lankan butterflies are poorly documented in the historical literature and there is a great need to identify LFPs in conservation perspectives. Therefore, the current study was designed and carried out during the past decade. A list of LFPs for 207 butterfly species (Super family Papilionoidea) of Sri Lanka is presented based on local studies and includes 785 plant-butterfly combinations and 480 plant species. Many of these combinations are reported for the first time in Sri Lanka. The impact of introducing new plants on the dynamics of abundance and distribution of butterflies, the possibility of butterflies being pests on crops, and observations of LFPs of rare butterfly species, are discussed. This information is crucial for the conservation management of the butterfly fauna in Sri Lanka. Key words: conservation, crops, larval food plants (LFPs), pests, plant-butterfly combination. Introduction Butterflies go through complete metamorphosis 1949). As all herbivorous insects show some and have two stages of food consumtion. -

Taxonomic Enumeration of Angiosperm Flora of Sreenagar Upazila, Munshigang, Dhaka, Bangladesh
J. Asiat. Soc. Bangladesh, Sci. 43(2): 161-172, December 2017 TAXONOMIC ENUMERATION OF ANGIOSPERM FLORA OF SREENAGAR UPAZILA, MUNSHIGANG, DHAKA, BANGLADESH ZAKIA MAHMUDAH, MD. MUZAHIDUL ISLAM, TAHMINA HAQUE AND MOHAMMAD ZASHIM UDDIN1 Department of Botany, University of Dhaka, Dhaka-1000, Bangladesh Abstract The present article focuses the status of angiosperm flora of Sreenagar upazila under Munshiganj district. The study was done from July 2015 to June 2016. A total of 219 plant species of angiosperms was identified belonging to 165 genera and 70 families. Among them 38 species were monocotyledons and 181 plant species were dicotyledons. Herbs were the largest life forms among the angiosperms and contained about 58% of total plant species occurring in this area. Trees and shrubs occupied 23% and 12% respectively. Climbers were 6% but epiphytes (1%) were very negligible in number in the study area. About 51 medicinal plants were recorded from this study. The following species viz. Lasia spinosa, Calamus tenuis, Tinospora crispa, Passiflora foetida and Calotropis procera were recorded only once and hence considered as rare species in Sreenagar upazila. An invasive poisonous plant Parthenium hysterophorus was also found in Sreenagar. Key words: Diversity, Angiosperm flora, Sreenagar, Munshiganj district Introduction Sreenagar is an upazila under Munshiganj district situated on the bank of ‘Padma’ river. It is a part of Dhaka division, located in between 23°27' and 23°38' north latitudes and in between 90°10' and 90°22' east longitudes. The total area is 202, 98 square kilometer and bounded by Serajdikhan and Nawabganj upazilas on the north, Lohajong and Shibchar upazilas on the south, Serajdikhan and Nawabganj and Dohar upazilas on the west. -

Homalopoa has diversified extensively in the Americas. Over half of the species in the supersection are diclinous; most of these are from the New World, while a few are from South-East Asia. Diclinism in Homalopoa can be divided into three main types: gynomonoecism, gynodioe- cism and dioecism. Here the sampling of species of New World Homalopoa is expanded to date its origin and diver- sification in North and South America and examine the evolution and origin of the breeding system diversity. Methods A total of 124 specimens were included in the matrix, of which 89 are species of Poa supersect. http://aob.oxfordjournals.org/ Homalopoa sections Acutifoliae, Anthochloa, Brizoides, Dasypoa, Dioicopoa, Dissanthelium, Homalopoa sensu lato (s.l.), Madropoa and Tovarochloa, and the informal Punapoa group. Bayesian and parsimony analyses were conducted on the data sets based on four markers: the nuclear ribosomal internal tanscribed spacer (ITS) and exter- nal transcribed spacer (ETS), and plastid trnT-L and trnL-F. -
Four Master Teachers Who Fostered American Turn-Of-The-(20<Sup>TH

Petersen Department of Ecology & Evolutionary Biology, University of Tennessee Knoxville, TN 37919-1100 Correspondence to: [email protected] Abstract—The Morrill Act of 1862 afforded the US states the opportunity to found state colleges with agriculture as part of their mission—the so-called “land-grant colleges.” The Hatch Act of 1887 gave the same opportunity for agricultural experiment stations as functions of the land-grant colleges, and the “third Morrill Act” (the Smith-Lever Act) of 1914 added an extension dimension to the experiment stations. Overall, the end of the 19th century and the first quarter of the 20th was a time for growing appreciation for, and growth of institutional education in the natural sciences, especially botany and its specialties, mycology, and phytopathology. This paper outlines a particular genealogy of mycologists and plant pathologists representative of this era. Professor Albert Nelson Prentiss, first of Michigan State then of Cornell, Professor William Russel Dudley of Cornell and Stanford, Professor Mason Blanchard Thomas of Wabash College, and Professor Herbert Hice Whetzel of Cornell Plant Pathology were major players in the scenario. The supporting cast, the students selected, trained, and guided by these men, was legion, a few of whom are briefly traced here. Key words—“New Botany,” European influence, agrarian roots Chapter 1.

PART II PERSONAL PAPERS AND ORGANIZATIONAL RECORDS Allen, Paul Hamilton, 1911-1963 Collection 1 RG 4/1/5/15 Photographs, 1937-1959 (1.0 linear feet) Paul Allen was a botanist and plantsman of the American tropics. He was student assistant to C. W. Dodge, the Garden's mycologist, and collector for the Missouri Botanical Garden expedition to Panama in 1934. As manager of the Garden's tropical research station in Balboa, Panama, from 1936 to 1939, he actively col- lected plants for the Flora of Panama. He was the representative of the Garden in Central America, 1940-43, and was recruited after the War to write treatments for the Flora of Panama. The photos consist of 1125 negatives and contact prints of plant taxa, including habitat photos, herbarium specimens, and close-ups arranged in alphabetical order by genus and species. A handwritten inventory by the donor in the collection file lists each item including 19 rolls of film of plant communities in El Salvador, Costa Rica, Honduras, Nicaragua, and Panama. The collection contains 203 color slides of plants in Panama, other parts of Central America, and North Borneo. Also included are black and white snapshots of Panama, 1937-1944, and specimen photos presented to the Garden's herbarium. Allen's field books and other papers that may give further identification are housed at the Hunt Institute of Botanical Documentation. Copies of certain field notebooks and specimen books are in the herbarium curator correspondence of Robert Woodson, (Collection 1, RG 4/1/1/3). Gift, 1983-1990.
