Wolden Emmett County, Iowa Plant project

From 1917 to 1951(?) B.O. Wolden collected plants through out Emmett County, especially around High Lake. These plants were stored (but uncatalogued) at the Ada Hayden herbarium, but are now stored (and cataloged) in the Iowa Lakeside Laboratory Herbarium (ILH) and are listed in the attached excel sheet. He also produced a map of where he collected the specimens, which is the purpose of this documentation.

1917年至1951年（时间存疑）期间，B.O.沃尔登（B.O. Wolden）在埃米特县全境采集植物标本，采集区域尤以海伊湖周边为重。
这批标本最初被存放于埃达·海顿标本馆（Ada Hayden Herbarium），但未进行编目；如今它们已移交至爱荷华湖滨实验室标本馆（Iowa Lakeside Laboratory Herbarium，简称ILH）并完成编目，相关标本信息已收录于随附的Excel工作表中。
此外，沃尔登还绘制了一份其标本采集地点的分布图，这正是本文档的编制初衷。
