Notes on the Spinulose Wood-Ferns

Abstract

lowlands of southeastern Missouri. This is in accordance with our previous record, for the only locality known for it in the state was in Butler County, over two hundred miles eastward. So its discovery in a rocky upland station in western Missouri only a few miles from the Kansas border is of unusual interest. The collection record is as follows: E. J. Palmer, no. 53158, wet springy ground below sandstone ledge, along Horse Creek, 3 miles northeast of Milford, Barton Co., September 22, 1951, alt. approximately 270 meters. A second collection was made at the same locality, under no. 53205, September 25, 1951. Collections of the plants discussed above are to be found in the Chicago Natural History Museum Herbarium, and it is planned to send duplicate material to Gray Herbarium, Missouri Botanical Garden Herbarium, and the United States National Herbarium. The Marsilea and Woodwardia collections are also to be found in the private herbarium of the senior author. WEBB CITY, MISSOURI, AND CHICAGO NATURAL HISTORY MUSEUM AND MISSOURI BOTANICAL GARDEN.
