SOME MAINE RUBI. THE BLACKBERRIES OF THE 

 KENNEBUNKS AND WELLS,— II. 



W. H. Blanchard. 



Ten species and one variety are considered in this paper and the 

 Hispidns and Setosu.'i classes must be left for a third paper. The 

 first six of the following species are erect " high" blackberries belong- 

 ing to four distinct classes two of which are new; and the remaining 

 four are recurving and tipping, forming three equally distinct new 

 classes. 



* Erect Blackberries, recurving .slight h' or not at all; never tipping. 

 H- The Nigrobaccus class. Inflorescence a long tapering open raceme. 



RuBUS NIGROBACCUS, Bailey. This is abundant and fruits well in 

 parts of Wells, but is generally occasional only, though it occurs in all 

 situations down to the edge of the ocean. Wherever found it has 

 plainly the distinguishing characteristics of the species, and does not 

 seem to intergrade with or into anything else as Prof. L. H. Bailey 

 has taught. It is very pubescent and hairy \\-ith stalked glands on 

 all parts often even on the surfaces of the leaves. The new canes 

 have strong furrowed stems, often branched, with stout straight 

 prickles set on the ridges at a right angle, and 5-foliate light yellow- 

 green leaves, the leaflets mostly ovate and long-stalked. The old 

 canes are pyramidal in outline, the leaf branches closely resembling 

 new canes. * The inflorescence is a long tapering raceme nearly leaf- 

 less, very loose and open, the pedicels set at a great angle to the axis. 

 The petals are long and narrow, the fruit long and tajiering; a good 

 fruit having from 6() to 100 small drupelets each about | in. in diameter; 

 very aromatic but very seedy. 



Rubus orarius, n. sp. Plants large and very erect, pyramidal in 

 outline with stout furrowed stems, (rlabrous or somewhat pubescent; 

 glandless or somewhat glandular on the inflorescence. Leaflets 

 broad; fruit large and useful, in large open racemes.
