The distribution of the native orchids of Iowa was determined through herbarium and field studies. Twenty-five species have been collected in Iowa: Aplectrum hyemale (Muhl. ex Willd.) Torr., Calopogon tuberosus (L.) BSP., Coeloglossum viride (L.) Harem. var. virescens (Muhl.) Luer, Corallorhiza maculata Raf., Corallorhiza odontorhiza (Willd.) Nutt., Cypripedium calceolus L. var. pubescens (Willd.) Correll, Cypripedium candidum Muhl. ex Willd., Cypripedium reginae Wale., Galearis spectabilis (L.) Raf., Goodyera pubescens (Willd.) R. Br., Liparis lilifolia (L.) L. C. Rich., Liparis loeselii (L.) L. C. Rich. , Malaxis unifolia Michx., Platanthera clavellata (Michx.) Luer, Platanthera flava (L.) Lindl. var. herbiola (R. Br.) Luer, Platanthera hookeri (Torr.) Lindl., Platanthera hyperborea (L.) Lindl., Platanthera leucophaea (Nutt.) Lindl., Platanthera psycodes (L.) Lindl., Pogonia ophioglossoides (L.) Ker-Gawl., Spiranthes cernua (L.) L. C. Rich., Spiranthes lacera (Raf.) Raf., Spiranthes romanzoffiana Cham., Spiranthes vernalis Engelm. & Gray, and Triphora trianthophora (Sw.) Rydb. Two natural hybrids have also been collected in Iowa: Cypripedium x andrewsii Fuller (C. calceolus var. pubescens x C. candidum), and Spiranthes lacera x S. cernua. A distribution map and the location of herbarium specimens is given for each species.
