Rydberg in the North American Flora (xxii. 474, 475) assigns B. 

 procumbent Muhl. a range from "Maine to Virginia," etc., but treats 

 B. recurtieaulis, which is common in Nova Scotia and Newfoundland, 

 as B. pergratus x procumbent. In view of the fact that neither R. 

 pergratus nor ft. procumbens is known in either Nova Scotia or New- 

 foundland B. recurtieaulis would seem, by H yd berg's interpretation, 

 to be one of the absent treatment hybrids so popular with many stu- 

 dents of Rubus. Rydberg includes other such supposed hybrids on 

 the same page (in view of the fact that B. procumbent is unknown 

 from east of southern Maine): " It. canadensis X procumbent . 

 Nova Scotia and Maine" and "It. kispidus X procumbent .... 

 Nova Scotia to Vermont and Long Island, New York."
