218 Rliodora [November 



berry, the plant that Dr. Porter named R. AUeglmnicnsls and Prof. 

 Baik'y hiter named R. nigroharcus. Its range is from northern New 

 England and New York (except at considerable elevations where R. 

 Canadensis holds sway, 7?. prrgratus in some places occurring also) 

 to the low coast (beginning near Boston) and the adjacent valleys 

 and sand plains. It extends to Northern New Jersey, occurs in spots 

 in Southeastern Pennsylvania, and seems to be frequent in the Pocono 

 Mountains. 



The other which is a more southern plant has its northern limit 

 at an elevation of about 200 feet in Connecticut and Rhode Island 

 occupying about one-fourth of Connecticut and one-half of Rhode 

 Island. It follows the coast and sand plains of Massachusetts to Bos- 

 ton. This is R. Andrewsianus described by the writer in Rhodora, 

 Jan., 1906. As it occurs in Southington, Connecticut, it bears very 

 poorly but nearer the coast and in Pennsylvania, New Jersey and 

 Virginia it is an abundant bearer. The fruit is large, the drupelets 

 loose and large. The fruit is sweet but not aromatic. AVhere the two 

 species overlap this is much the earlier and seems to be the parent of 

 most of the cultivated forms. 



This information the writer has obtained by personal search, though 

 an examination of several private herbaria and those of Brown Uni- 

 versity, Yale University, New York Botanical Garden, Philadelphia 

 Academy of Sciences and the National Herbarium at Washington 

 have confirmed it. 



It appears that when Dr. Porter found 7?. AJIeghanirnsis it was so 

 different from what he had called R. vi/losus — tlie plant now named 

 R. Andrciv.^-ianus- that he published it as a variety and later as a species. 

 Note his description. "It diffcM's from R. vi/losus in being less robust 

 and tall but especially in the character of the fruit which is smaller, 

 scarcely fleshy and [)()ssessed of a j)eculiar spicy flavor from i^ to 1 in. 

 or more in length and often oblong and tapering toward the end in 

 the manner of the little finger." Prof. Bailey would hardly have pub- 

 HsIumI R. nigrohaccus if he had known the plant Dr. Porter called R. 

 villosus. He hesitated, as it was, thinking Dr. Porter's name might 

 be correct. There seems, however, to be no doubt that Dr. Porter 

 was the first to segregate our spicy blackberry, and that its name 

 should be R. AUeghaniensis.
