R. JeckyJanus belong to the Frondosus class. R. jrondosus seems 

 to deserve notice here. 



RuBUS FRONDOSUS Bigelow. This fine species, which was described 

 eighty years ago and which is very abundant about Boston, seems 

 never to have been recognized and there are few herbarium specimens 

 extant. One is a short undeveloped fruit branch in bud sent by Dr. 

 Bigelow to Dr. Torrey in 1823. In the letter accompanying it he 

 characterized it much as in his description published soon after in the 

 second edition of his "Florula Bostoniensis." This letter is preserved 

 at the New York Botanical Garden. A second specimen is a fruit 

 branch in flower collected recently by Mr. W. P. Rich. A third is 

 also a flowering branch collected recently on the Arboretum grounds 

 at Jamaica Plain. These two are preserved in the Arboretum her- 

 barium. The writer had assumed that the Boston botanists had se- 

 cured the common plants in that section and not till late in August 

 (1906) did he look around there. The species in question was soon 

 found at Cobb Corner in Sharon and near Sharon Heights. After- 

 wards it was observed at the following stations: Canton, Arlington, 

 Lexington, Medford, Winchester, Stoneham, Belmont, Sudbury, Fram- 

 ingham, Wayland, Clinton, and Milton. It is especially abundant on 

 the hill between Arlington village and Lake Mystic, and in Clinton two 

 miles south of the Wachusett dam in the pastures bordering the east 

 side of the reservoir near the Electric Railroad. It is to be distin- 

 guished at sight from the other "high bush" blackberries by its strong, 

 round stem, abundant long recurving branches which touch and lie 

 upon the ground but do not appear to tip, leaves thick, roughly pubes- 

 cent, leaflets very broad, the middle one only stalked. The old cane 

 j)reserves its leaves till autumn the fruit ripening early and falling 

 while all the leaves even on the inflorescence remain. The inflores- 

 cence is a close cyme with many of the pedicels subtended by broad 

 leaves. No name could be more appropriate. It is occasional in 

 Connecticut and Rhode Island. 



RuBus Alleghaniensis Porter. {R. nigrohaccus Bailey, R. villosus 

 Gray's Manual in part.) There are two very common, very char- 

 acteristic and very dift'erent species of high blackberries in the eastern 

 part of the United States. They constitute the bulk of the high 

 blackberries from Maine to New York and south to North Carolina. 

 They encroach very little on each other's territory. One is a northern 

 .plant with a delicious spicy flavor to be compared only with the straw-
