Notes on Iowa Vascular Plants

Recent collecting and studying in herbaria have called forth the following notes on some of the rarer plants of Iowa. The writer\u27s collections have been, or will be, deposited in the herbaria of Iowa State Teachers College (ISTC), Iowa State College (ISC), the State University of Iowa (SUI), and, for Dickinson County plants, the Iowa Lakeside Laboratory at Lake Okoboji (ILL). Accordingly, herbarium citations are not given for the writer\u27s collections. This article contains notes on 16 species of monocots and 26 of dicots, with one conifer, a total of 43 species, representing 17 families, principally Lemnaceae (5), Orchidaceae (10), Rosaceae (4), Leguminosae 7), and Campanulaceae (3) . There are treated two new albino color forms (Linum sulcatum and Campanula americana) , notes on three other color forms, one new state record ( Petalostemon villosus), 16 range extensions with summaries of distribution, 11 descriptions of recent collections of rare plants with summaries of distribution, and 9 other distributional items
