  • 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.

  • 1/22 Hygroscopic Awns of Two Prairie Grasses, Andropogon Gerardii And
    1/22 Hygroscopic awns of two prairie grasses, Andropogon gerardii and Sorghastrum nutans A THESIS SUBMITTED TO THE FACULTY OF THE PROGRAM IN PLANT BIOLOGY AND CONSERVATION BY JOSHUA MICHAEL DRIZIN IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN PLANT BIOLOGY AND CONSERVATION FROM NORTHWESTERN UNIVERSITY AND THE CHICAGO BOTANIC GARDEN May 16, 2013 2/22 3/22 Abstract The prairie grasses Andropogon gerardii and Sorghastrum nutans have seeds with awns that twist in response to changes in humidity. The humidity-sensitive, or hygroscopic, part of the awn twists, moving the bent, passive portion in an arc. This trait has been demonstrated to improve seedling recruitment in other grass species by dispersing the seeds to superior microsites. Hygroscopicity was defined as the time taken for the awn to complete one rotation. The goals were to 1. estimate heritability of hygroscopicity, 2. assess population-level differences in hygroscopicity, and 3. examine the relationship between hygroscopicity and seed movement. Two sets of seed were used. Seeds were collected in west-central Minnesota from individual maternal plants in remnant and restoration populations and were grown out to collect a second seed generation, used to assess heritability. To assess population differences and unidirectional movement, seeds were purchased from conservation seed suppliers from across the species' range. Time-lapse photography and humidity manipulation were used to characterize seed movement. I found a weak trend of heritability in Andropogon but not Sorghastrum. Northern populations of Sorghastrum spun more slowly than those of southern populations. There was no difference in rotation time among Andropogon populations.

S. Hitchcock, revised by Agnes Chase (1951). iii PREFACE The first part of our Annotated Checklist, covering the 2001 species of Ferns, Fern Allies, Gymnosperms, and Dicotyledons native or naturalized in the Washington-Baltimore Area, was published in March 2000. Part II covers the Monocotyledons and completes the preliminary edition of the Checklist, which we hope will prove useful not only in itself but also as a first step toward a new manual for the identification of the Area’s flora. Such a manual is needed to replace the long- outdated and out-of-print Flora of the District of Columbia and Vicinity of Hitchcock and Standley, published in 1919. In the preparation of this part, as with Part I, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. As with the first part, we are distributing this second part in preliminary form, so that it can be used, criticized, and updated while the two parts are being readied for publication as a single volume.

I would like to extend my thanks to the authorities of both institutions, and their staff, who offered help in many ways. My collection of living material was cared for by Messrs Billy Adams and Bob Astles. I wish to thank them for their help. My thanks also go to members of the photographic unit of ICMB, particularly John Anthony, Dave Haswell and Frank Johnston, for their help. Mr. John Findlay (Botany Department) gave me guidance with my SEM work, for which I am grateful. I am indebted to the Directors of various herbaria who loaned me specimens. Helen Hoy and Marisa Main were in charge of the Edinburgh side of these loans.

  • Lopsided Indiangrass (Sorghastrum Secundum)
    Lopsided indiangrass (Sorghastrum secundum) For definitions of botanical terms, visit en.wikipedia.org/wiki/Glossary_of_botanical_terms. Lopsided indiangrass is a robust and unique perennial bunchgrass. It occurs naturally in pinelands, sandhills and flatwoods, and typically blooms in late summer through fall. It is the larval host plant for the Delaware skipper, Dusted skipper and Swarthy skipper. Throughout most of the year, Lopsided indiangrass is rather indistinct. But in late summer, it produces tall, dramatic flower spikes. Each tiny flower is wrapped in bracts that are covered in soft, bronze to brown hairs, and bears a long, twisted, reddish- brown awn and bright yellow anthers. When Photo by Katherine Edison lit by the sun, the colorful flowerheads flicker and flash. The entire inflorescence occurs on one side of the rachis, hence the common descriptor “lopsided.” Leaves are dark green with long, tapering blades up to 18 inches long. Leaf sheaths are covered in fine hairs. The genus name Sorghastrum literally translates to “poor imitation of Sorghum.” It is a combination of the genus Sorghum and the Latin suffix astrum- , meaning “expressing incomplete resemblance.” The species epithet secundum is from the Latin secundus, meaning “following,” “next” or (loosely) “in a row” and refers to the formation of flowers on one side of the rachis. Family: Poaceae (also called Gramineae or true grasses) Native range: Mostly throughout Florida To see where natural populations of Lopsided Indiangrass have been vouchered, visit www.florida.plantatlas.usf.edu. Hardiness: Zones 8A–11 Soil: Moist to dry, well-drained soils Exposure: Full sun to minimal shade Growth habit: 2–3’ feet; up to 6’ tall when flowering Propagation: Seed, division Garden tips: Lopsided Indiangrass is primarily recommended for naturalistic landscapes and habitat restorations.
