than in the preceding. It can easily be distinguished by the sharp 
tips to the scales of the involucre, and by the prominent spinose tips 
to the chaff, on the disk. 
Lefroy did not distinguish the two species, but both are figured by 
Hemsley in Voy. Challenger, Bot., i, pl. 1, ii. 
Sea-side Golden-rod. (Solidago sempervirens L.) 
This fine golden-rod, which is the same as the common one of the 
New England coast, is very common about high-water mark, and a 
little beyond it. It is not injured by the partial daily immersion of 
its roots in sea-water, nor by salt spray. Found also in the Azores. 
Dog-bush ; Groundsel Tree. (Baccharis glomerulifiora Pers.=B. 
heterophylla in Lefroy’s list.) 
This composite shrub is abundant and apparently native in Pem- 
broke Marsh and probably elsewhere. It is found on the salt 
marshes of the American coast, as far north as North Carolina. 
Flowers white, appearing at Bermuda in December (Lefroy). The 
ripe seeds have a long downy pappus. 
Black Berry. (Scevola lobelia L.)

This native shrub is one of the most important plants for binding 
the drifting sands on the sand-dunes close to the sea, as at Tucker’s
