Further Notes on the Pteridophytes of San Diego County, California

The recent contribution of Ira L. Wiggins on the of San Diego County, California, 1 forms another link in the series of papers dealing with the California ferns and fern allies. This chain was first started in the Fern Bulletin by Parish,2 later continued by Parish3 and Munz and Johnston4 for Southern California and now localized by Wiggins for San Diego County. Miss Kimball in 19115 published in the Fern Bulletin a short article on the San Diego County ferns but due to the difficulty of field trips she was unable to report on our mountain and desert species. Wiggins, when one considers that the Pteridophytes were only a small part of his research work on the San Diego County Flora, has covered the county in a very satisfactory manner. Any one who has ever had the pleasure of collecting in this region can well appreciate the work that he has done. The following additional stations (all easily reached by car) are now added to those already recorded by Wiggins, together with several species new to his checklist. Specimens examined are either in our local Natural History Museum, in Miss Kimball's collection or in my own personal herbarium. Thanks are due to Miss Kimball for her assistance in identification of the species.

The Pteridophytes of Muskogee County, Oklahoma

A list of the pteridophytes of an Oklahoma county will emphasize the relative scareity of ferns in the grassland interior of the country. Although more than fifty species have been collected in the state, many of these are restricted to the eastern forested parts and several others are western species of limited distribution in Oklahoma. In a detailed study of the flora and vegetation of Muskogee County made by the writer' from 1925 to 1929, a list of the pteridophytes was included. The collection of Muskogee County specimens has been deposited in the Herbarium of the University of Oklahoma. Although about 800 species of seed plants were collected, only 11 ferns and fern allies were noted. This is probably a greater number of pteridophytes than can be found in most counties in central and western Oklahoma. Muskogee County, having an area of 826 sq. mi., is located in northeastern Oklahoma in the transition zone between the oak-hickory forest on the east and the grassland on the west. Ferns do not grow in the commonest type of native vegetation, the tall grass prairie. Low hills of sandstone in the county are covered with the oakhickory forest and support ferns on the rock outcrops and rocky soil. One sandstone hill, appropriately named Fern Mountain, has a variety of ferns. It is the only known station in the county for two species and one of two stations for a third fern. Limited outcrops of limestone, which have a mesophytic maple-oak forest, occur on hillsides at the western border of the Ozark plateau.

Ferns and Fern Allies of Missouri

This paper is based primarily upon material in the herbarium of the Missouri Botanical Garden, the University of Missouri, and the private collections of Mr. John H. Kellogg and of the author. After each specific name reference is given to the original publication; this is followed by reference to the two standard manuals and to an illustrated monograph covering the fern-flora of the region concerned, where the species or variety is treated under the same or a different name. These are: Gray, 'New Manual of Botany,' ed. 7, 1908; Britton and Brown, 'Illustrated Flora of the Northern States and Canada,' ed. 1 1896, and ed. 2, 1913; and Eaton, 'Ferns of North America,' vol. 1, 1879 (plates 1-45) and vol. 2, 1880 (plates 46-81). Time of fruiting, the general distribution for North America, and the habitat for Missouri in particular precede the specific description. The names of the principal collectors whose material was examined are listed, and definite citations made when the plant is rare. KEY TO FAMILIES

Ferns and Fern Allies of Lancaster County, Pennsylvania, 1931 and 1932

During the years 1931 and 1932 the following ferns and fern allies have been found in Lancaster County, Pennsylvania, by a group of half a dozen fern students, beginners all. Lancaster County, an area of over 960 square miles, is a very beautiful region of varied topography and soil belts and consequently has a rich and diversified flora. The great Susquehanna River valley, along its southern edge, in which the rocks are predominantly mica-gneiss, is rich in the rare Aspleniums. The lovely river glens, moist and shady, with a deep accumulation of rich leafmold, contain a greater number of species than any other section. To the north is a mountainous region of red sandstone soil. The great central basin is a limestone region, comprising some of the richest farm land in the country. To the southeast is a serpentine belt. The whole offers a remarkable inspiration and challenge to the botanist. OPHIOGLOSSUM VULGATUM L. One station, a swampy field near the Dillerville swamp. BOTRYCHIUM MATRICARIAEFOLIUM A. Braun. Two stations. About twenty-five plants in a ravine at Martic Forge and one plant, very large and healthy, in the Muddy Run ravine. BOTRYCHIUM OBLIQUUM MAuhl. Common. BOTRYCHIUM DISSECTUM Spreng. Common. BOTRYCHIUM ANGUSTISEGMENTUM (Pease and Moore) Fernald. Two stations. Five plants in a ravine at Martic Forge and nine in the Muddy Run ravine. BOTRYCHIUM VIRGINIANUM (L.) Sw. Common. OSMUNDA REGALIS L. Common. 13

Additions to the Fern Flora of New York State

New York State has been rather thoroughly explored for interesting and rare specimens of the ferns and fern allies by botanists in general and fern students in particular. Hence the discovery of two species new to the fern flora of the State constitutes an event of some consequence to fern enthusiasts. ASPLENIUM VIRIDE Huds. Moist shale cliff in Whetstone Gulf, Lewis County, Neil Hotchkiss 2613, 1927. No attempt has heretofore been made to give undue publicity to this interesting find although it has recently been recorded by Mr. Hotchkiss in his Botanical Survey of the Tug Hill Plateau (N. Y. State Museum Bulletin 287, page 58, 1932). Only a few individual fronds and no roots were collected from the few sparsely scattered plants and it is to be sincerely hoped that others who visit the locality will be fully as considerate. WOODSIA OREGANA D. C. Eaton. Ledge overlooking Canandaigua Lake, South Bristol, Ontario County, E. H. Eaton, July 20, 1929, and July 15, 1931. First found there by Mr. Eaton in August, 1925. The first collection sent to me by Mr. Eaton was submitted to both Mr. C. A. Weatherby, of the Gray Herbarium, and Dr. William R. Maxon, of the National Museum. Dr. Maxon stated that the specimens were not satisfactory

The Ferns and Fern Allies of Missouri

The fern flora of eastern North America attains its maximum development in the number of species as well as in the luxuriant abundance of many of them, in the northeastern states and in the Appalachian Mountains. The number of species diminishes gradually westward, and most of them have disappeared in the plains states, although some few extend to the Rocky Mountains, where they meet many species from the west and south, and a few of the latter range eastward as far as the Mississippi Valley. The State of Missouri, situated about half-way between the northern and southern boundaries and somewhat east of the geographical center of the United States, embraces the western range limit of several species of ferns and fern allies. Both on account of its central geographical position and of the great diversity of its topography and of its rocks and soils, the fern flora of the state is somewhat richer and more diverse than that of most of the surrounding states. Three distinct topographical regions are found in the state, and several more or less well-marked subdivisions of these might be recognized on the basis of geological formations and soils. The three main divisions from

IN October 1929 the first volume of this important work made its appearance. It included all plants from Aa to Campanopsis. The editor, Dr. Stapf, and his collaborators have now brought their great task one stage further with the issue of Vol. 2, which appeared about Christmas 1929, but is dated 1930. It consists of 548 pages and is, therefore, of almost exactly the same size as Vol. 1. It comprises references to illustrations of all plants from Campanula to Dysphania inclusive. The Clarendon Press is once more to be congratulated on the excellence of the printing.
