The Morphology Of The Pine Cone, Charles E. Bessey

Papers in Systematics and Biological Diversity

So much has been said in regard to the morphology of the cone of the pine and its near allies that it would seem impossible as well as unnecessary to suggest anything further. However, the recent excellent summary in Coulter and Chamberlain's “Morphology of the Spermatophytes" of the many theories hitherto advanced to clear up the matter, and the conclusions reached by the authors named, show that it is by no means settled, and perhaps warrant me in presenting an interpretation which I have used in lectures before my own classes for half a dozen years or more.

The Modern Conception Of The Structure And Classification Of Diatoms, Charles E. Bessey

Papers in Systematics and Biological Diversity

In the revision of the Bacillariaceae for Engler and Prantl's “Pflanzenfamilien," Schutt has availed himself principally of the studies of Otto Muller and has given us the first clear conception of the meaning of the diatom cell, and its relation to the diatom filament. Starting with the filament, we regard it as the typical condition, from which the unicellular diatoms have been derived by the solution of the filament and the adaptation of the separate cells to an independent life. Diatoms are thus regarded as typically filamentous algae, and are no longer to be placed among unicellular plants. Accordingly their …

Botanical Specimens (Herbarium) By Helen J. Monahan, 1899, Helen J. Monahan

Botanical Specimen Books

This botanical specimen book was collected and curated by Helen J. Monahan in 1899 for a Botany course taught by John M. Holzinger at the Winona Normal School in Winona, Minnesota. Helen Josephine (Monahan) Rowekamp (1885-1967) was born in Witoka, Minnesota. She attended the Winona Normal School. In 1916 Helen (Monahan) Rowekamp married Julius Rowekamp and they farmed in the Lewiston area until 1947 when they moved to Winona. Mrs. Rowekamp's death was announced in The Winona Daily News on Sunday, March 05, 1967.

The Phytogeography Of Nebraska, Roscoe Pound, Frederic E. Clements

Papers in Systematics and Biological Diversity

From the preface we learn that this work is the result of nearly five years of active study of the floral covering of Nebraska, carried on by the members of the Botanical Seminar in the Botanical Survey of the State of Nebraska. The systematic study of the vegetation of Nebraska was begun by Dr. Bessey in 1884, and has since been carried on by him and his students, all previous collecting having been more or less desultory and unreliable. The Botanical Survey was organized in 1892, and its work has been directed to the collecting of specimens and observations for …

Observations Of The Adaptation Of The Leaves Of Kalmia Latifolia To Environment, Grace Ellen Wilson

Student and Lippitt Prize Essays

Samples taken from the plant for observation are from two different locations (high dry land with full sun/low moisture and a swamp) and show that the leaves of the plant flourish more in sunlight than in dark, swamp areas.

Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey

Papers in Systematics and Biological Diversity

It is unnecessary for me to state at the outset what is evident to every botanist, that it is as yet impossible to present a complete phylogeny of the angiosperms. Phytopaleontology is too young a science, and the materials with which it deals are yet far too scanty to have given us direct evidence as to the phylogeny of all families of plants. No one can trace with great certainty from the fossil remains of plants yet discovered the genealogy of any considerable portion of the vegetable kingdom. It will be many a year before the direct evidence we so …

Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893, Per Axel Rydberg

School of Biological Sciences: Dissertations, Theses, and Student Research

Rydberg (1860–1931) was born Sweden and emigrated to the United States in 1882, first to mining camps in upper Michigan and eventually to Wahoo, in Saunders County, Nebraska, where he taught mathematics from 1884 to 1893 at now defunct Luther Academy. In the summers of 1891-1893, 1895, and 1896 he was a field agent for the United States Department of Agriculture and collected plants in Nebraska, South Dakota, Montana, Idaho, Wyoming, and Colorado, and specimens from those and other trips are in the Bessey Herbarium at the University of Nebraska–Lincoln, which house what is now known as the Charles E. …

A Study Of The Forage Plants Of South Dakota With Their Fungous And Insect Enemies, David Griffiths

Electronic Theses and Dissertations

The main object of this study being a better acquaintance with fungous parasites, the work on the host plants has been considerably abridged in order that the discussion might be shortened. It was the plan at first to include in this paper a carefully written description of each of the principal forage plants of the state. The futility of such a plan, however, soon became apparent, and it was accordingly decided to omit the description and include simply Distribution,

Habitat, Value as Forage, and the Fungous Parasites of each host. There are, therefore, several of our best forage plants omitted …

A Second Report Upon The Native Trees And Shrubs Of Nebraska, Charles E. Bessey, Robert Bolin , Depositor

School of Biological Sciences: Faculty Publications

Dr. Bessey was then Nebraska State Botanist and “Professor of Botany, State University, Lincoln Nebraska.” The State University is now called that University of Nebraska–Lincoln. This document was published as a contribution to the knowledge of the native woody plants of the state. Several reports had been published previously each containing additions and corrections. This report contains a “Special Request” that asked readers around the state to send samples of native trees and shrubs to the author.

The report contains a classification list of the various trees and shrubs along with information about where they can be found. A table …

A Meeting-Place For Two Floras, Charles E. Bessey

Papers in Systematics and Biological Diversity

About half-way across the northern part of Nebraska, a few miles east of the 100th meridian, there is a very interesting botanical locality. A small stream starts at a point about twenty or twenty-five miles south of the Niobrara River, and runs northward through a deep and winding canyon to the river mentioned. The surrounding country is absolutely treeless. and the surface is in many places thrown up into rounded hills of what must have once been drifting sand. The canyon sides are very abrupt, and they descend in many places fully two hundred feet before the bottom is reached. …

The Pinetum Britannicum, Edward Ravenscroft

Archives & Reprint Series (imprint)

The Pinetum Britannicum: A Descriptive Account of Hardy Coniferous Trees Cultivated in Great Britain was authored by Edward James Ravenscroft (1816-1890) during the time period of 1863 through 1884.

This first edition Pinetum Brittanicum is regarded as an important British study of pines. Edward James Ravenscroft’s exquisitely detailed illustrations exemplify the widely embraced enthusiasm for the art and science of capturing and classifying conifers during the 19th-century. Ravenscroft was a master in the field of natural history illustration, which is often called “art in the service of science.”

The Asparagus For Histological Study, Charles E. Bessey

Papers in Systematics and Biological Diversity

I have for several years been wanting a good Monocotyledon for histological study in the botanical laboratory, one which should be for its sub class what the pumpkin is for the dicotyledons. The indian corn, which is commonly used, is too difficult, and too greatly specialized a type, exhibiting as it does the peculiar nodal structure of the stem of the Grarninex, rather than the structure of the stem of monocotyledons in general. A good representative stem. and one which can be obtained everywhere in good condition, from early spring until the end of the season, is the asparagus. …

A Single Dendrometer, Charles E. Bessey

Papers in Systematics and Biological Diversity

A dendrometer is constructed essentially as follows: A tube, t, about two inches in diameter, and nearly or quite a foot in length, is supported in a vertical position by two pins, pp, near its upper end; and these pins rest upon a ring, r forming a simple gimbal which allows the tube by its own weight to assume an exactly vertical position. In the lower end of the tube two mirrors, A and B, are placed side by side, each occupying one half of the section of the diameter of the tube. One of these mirrors …

The Supposed Dimorphism Of Lithospermum Longiflorum, Charles E. Bessey

Papers in Systematics and Biological Diversity

The plant under consideration is a common herbaceous perennial of the prairies and great plains of North America. In the latter part of April and during the month of May it produces flowers with bright yellow salver-shaped (hypocraterimorphous) corollas, whose tubes are about thirty mm. (one and one-fifth inch) long, and from two to three mm. in diameter. About the first of June, in central Iowa, these large flowers suddenly disappear, and from this time forward until the autumn frosts, they produce only small cleistogamous flowers. The corolla lobes of the latter cohere somewhat, and remain closed, and …
