A Contribution to our Knowledge of the Wild and Cultivated Flora 



of Massachusetts — I 



Harold N. Moldenke 



The present paper comprises an annotated list of 223 collections of Massa- 

 chusetts plants, representing 192 species and subspecific entities in 155 genera 

 and 72 botanical families. It is one of a series by the same author on the flora 

 of each of the states of the United States, with the primary purpose in view 

 of recording county records for each species for the use of future compilers of 

 state Floras giving the distribution of each species in the state by counties. 1 

 The sequence of families followed is that of the author's preliminary classifica- 

 tion of the Plant Kingdom, based on the systems of Engler & Diels and of 

 J. Hutchinson. 2 



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

 dered the author by the following renowned specialists, who have examined 

 material of the groups noted after their names: Mr. E. J. Alexander (7m- 

 patiens), Dr. C. H. K. Blom (Stachys), Dr. Wendell H. Camp (V actinium), 

 Dr. Henry A. Gleason (Echinochloa) } Dr. Francis W. Pennell (Verb as cum), 

 Dr. John H. Pierce (Sagittaria) , and Dr. Henry K. Svenson (Carex). Each 

 collection cited on the following pages which was examined by one of these 

 specialists has the name of the specialist following the number in the list. 



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, Naturhistor- 

 iska 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, the herbaria at Krakow and Vyskov, and elsewhere. The 

 collection numbers, for citation purposes, are all H. N. Moldenke collection 

 and citation numbers, although some of the material was actually collected by 

 other collectors and turned over to the author of this paper for identification 

 and distribution. These other collectors, with the numbers of their collections 

 and the dates when they collected in Massachusetts, are as follows : Miss Ellys 

 T. Butler, 1934 (8246) ; Mr. Stanley Conyes, 1942 (13313) ; Miss Alma L. 

 Ericson, 1932, 1938, 1939, 1941, 1942 (10750,, 11690—11708, 11776—11779,
