Rubus cuneifolius Pursh. Sand Blackberry. 



Rubus cuneifolius Pursh, Fl. Am. Sept. 347. 1814 [New Jersey to Carolina]. 

 —Barton, Fl. Phila. I. 232. 1818.— Knieskern 14.— Willis 21.— Britton 

 94- — Keller and Brown 174. 



Common in sandy ground throughout our region and recorded 

 at but two points farther north in the State — South Amboy and 

 Rosemont. 



This is the characteristic blackberry of southern New Jersey. 

 It does not grow high, usually not over three feet, but frequently 

 covers a considerable area of ground. The fruit is seedy and 

 too sweet and is not picked to any extent. 



Fl. — Late May to early July. Fr. — Mid-July to late August

 Harbor City, Quaker Bridge (UP).

Rubus argutus Link. Tall Blackberry. 



Rubus argutus Link, Enum. Hort. Berol. 11. 60 [North America]. — Keller 



and Brown 174. 

 Rubus villosus Britton 94 (in part.) — Knieskern 13 (in part.). 

 Rubus nigrobaccus Keller and Brown 174 (in part). 



Fields and thickets of the Middle and Coast districts and Cape 

 May peninsula ; common. Probably also in the northern counties. 



So variable are the Blackberries and so unsatisfactory the 

 character of most of the supposed species, that it is difficult to 

 decide whether we really have more than one species besides R. 

 cuneifolius. According to Mr. Bicknell's views, which seem to 

 be the most logical so far advanced, R. argutus should be the 

 name of the most abundant species of our coastal plain region. 



Fl. — Mid-May to mid-June. Fr. — Mid- July to mid-August. 



Middle District. — New Egypt, Crosswicks, Delanco, Medford (S).
