Additions To The Pteridophyte Flora Of Iowa-Iv, James H. Peck, Jeffrey C. Nekola, William Thomas
Journal of the Iowa Academy of Science: JIAS
This report updates field collection records and summarizes nomenclatural changes of genera and binomials of species of Iowa pteridophytes based on the Flora of North America project. Botrychium simplex var. compositum, Gymnocarpium jessoense (Koidz.) Koidz. spp. parvulum Sarvela, Gymnocarpium Xhrittonianum (Sarvela) Pryer & Haufler, and Gymnocarpium Xintermedium Sarvela were recently added to the state flora. The flora now consists of 66 species, plus 7 hybrids, and 1 distinct form, for a total of 74 taxa. With the addition of 81 new county occurrence records, the Iowa pteridophyte flora now consists of 1754 county occurrence records. A data matrix of species/county …

A Potential Understory Flora For Oak Savanna In Iowa, Karl T. Delong, Craig Hooper
Journal of the Iowa Academy of Science: JIAS
Oak savanna occurred in Iowa until the time of settlement and then was degraded rapidly. There were no scientific studies of savanna prior to, or after, settlement, and now no high-quality examples exist within the state. To identify those vascular plants adapted to live in the understory of savanna we examined regional and local flora for species that occurred in both prairie and broken woodland, and for species that occurred m both openings and forest. We then compiled a detailed description of the ecological range of habitats for each of these species. We identified 252 species (39 graminoids, 183 forbs, …

Additions To The Iowa Pteridophyte Flora - Iii, James H. Peck
Journal of the Iowa Academy of Science: JIAS
To prior reports on the studies of the Iowa pteridophyre flora, five taxa (Botrychium campestre Wagner & Farrar, Botrychimn matricariifolium A. Braun, CyJtopterislragilis (L) Bernh., Cystopteris laurentiana (Weath.) Blasdell, and Lycopodium inundatum L.) are added, along with 215 new county occurrence records for 39 taxa. Currently, the Iowa preridophyte flora consists of 70 taxa, supported with 1656 county occurrence records; only 72 (4%) of these records are based solely on collections made before 1950.
