 though very abundant to the north, is quite rare in the county, except 

 in a cultivated state, where, in the ordinary form or in the changed 

 condition, under the name of "Snowball Tree," it is common. The 

 only native locality yet noticed, is that in the deep Wenham Swamp, 

 where there are several large plants. 



Virburnum lantanoides, il/ic/ix. (Hobble-bush.) The flowers 

 of this species much resemble those of the last, except perhaps that 

 they are larger. The shrub is more straggling, however, and it is 

 more abundant, growing in nearly all the old deep woods of the 

 county, from Rockport to the Merrimac River.

 this species has been often reported as being found within the county, 

 yet the writer has not seen authentic specimens.

 in low ground throughout. Particularly fine in the hollows of Plumb 

 Island.
