A Contribution to our Knowledge of the Wild and Cultivated Flora 



of Delaware — I 



Harold N. Moldenke 



The present paper comprises an annotated list of 66 collections of Delaware 

 plants, representing 60 species and subspecific entities in 53 genera and 27 

 botanical families. It is one of a series by the same author on the flora of each 

 of the states of the United States and several foreign countries. 1 The sequence 

 of families followed is that of the author's preliminary classification of the 

 Plant Kingdom, 2 which, in turn, is based, with modifications, on the latest 

 available studies of the various groups — the systems of Engler & Diels and of 

 Hutchinson being followed in major part. 



It is a pleasure to acknowledge the generous and valuable assistance ren- 

 dered the author by Mrs. Agnes Chase, who identified the material of Era- 

 grostis and Panicum, the late Kenneth K. Mackenzie, who identified Carex, 

 and Dr. Francis W. Pennell, who identified Penstcmon. 



The first set of specimens herein cited is deposited in the Britton Her- 

 barium at The New York Botanical Garden ; other sets are in the herbaria 

 of the University of Pennsylvania, University of Illinois, Missouri Botanical 

 Garden, Duke University, Carthage College, Cornell University, Carnegie 

 Museum, Naturhistoriska Riksmuseum in Stockholm, Royal Botanic Gardens 

 in Kew, Botanisches Museum in Berlin, Botaniska Tradgard in Goteborg, 

 Conservatoire Botanique in Geneva, Jardin Botanique de l'Etat in Brussels, 

 British Museum (Natural History) in London, Jardin Botanique de 1'Uni- 

 versite Jagellonienne at Krakow, Vaclav Skrivanek herbarium at Vyskov, 

 and elsewhere. The collection numbers, for citation purposes, are all H. N. 

 Moldenke collection and citation numbers, although the material of numbers 

 7503 to 7516, inclusive, was actually collected by Dr. Charles Edward Mol- 

 denke 3 in 1933, the material of numbers 6680 to 6682, inclusive, was collected 

 by Dr. C. E. Moldenke and his wife, Mrs. Sophia Meta Moldenke, who col-
