LIST OF TREES AND SHRUBS. 299 



between the lobes are rounded, and the lobes themselves are 

 shorter, though the lamina of the leaf is cut to within a short 

 distance of its base. The European V. opuhis has generally 

 obtuse sinuses, and a less deeply cut lamina, but the lobes also 

 short. Pursh, who separated V. oxycoccus from edide, de- 

 scribed the bases of the leaves of the one as acute and of the 

 other obtuse ; but, as there seems to be no difference in that 

 respect, it is probable that he meant the sinuses. 



Diervilla trifida vel canadensis) bush honeysuckle, has a 

 herbaceous aspect, and is one of the most common underwoods 

 on the portages. It occurs in all the woody districts of the 

 Saskatchewan basin up to the acclivities of the Rocky Moun- 

 tains, but is rare to the north of Cumberland House. It grows 

 also on Lake Superior, in Wisconsin, Nova Scotia, and the 

 Northern States. Lonicera parviflora, small honeysuckle, has 

 a conterminous range with the preceding. L. douglasii gathered 

 on Saskatchewan is considered by Dr. A. Gray to be merely a 

 variety produced by cultivation. L. Jiirsuta, hairy honey- 

 suckle, is a coarse-leaved climber, common in moist rocky woods 

 of the Northern States, and Canada as far as Lake Huron,. L. 

 ciliata, fly honeysuckle, grows at Pictou, on the Catskill Moun- 

 tains, in Ohio, AYisconsin, generally throughout the rocky woods 

 of the Northern States ; also on Lake Superior, and northwards 

 along the whole Saskatchewan basin. L. ccerulea, the mountain 

 fly honeysuckle, extends northwards to the arctic circle ; it like- 

 wise ranges from the Labrador coast and Newfoundland to the 

 Rocky Mountains, and we should suppose also to the Pacific 

 coast, since it is both a European and a Siberian species ; but it 

 is not named by Mertens or Bongard among the Sitka plants, 

 nor does it appear to have been found by Douglas, Tolmie, or 

 Scouler in Oregon. It grows in Wisconsin, New Hampshire, 

 Massachusetts, and New York. 



Symphoricarpus racemosns, snow-berry, and S. occidentalis, 

 wolf-berry, range from Vermont, Michigan, and Wisconsin, over 

 the St. Lawrence and Saskatchewan basins, to the 60th parallel 

 on the Mackenzie. They also occur in the Oregon valley, Van- 

 couver's Island, and doubtless much further along that coast.
