COS RIOD o 
THE FLORA OF PENIKESE ISLAND. 
_ BY PROF. D. S. JORDAN. 
I etve here a list of the plants found on the Island of Penikese, 
and in the waters of Buzzard’s Bay in the neighborhood of the 
island, during the late session of the Anderson School of Natural 
History. This list is probably complete in the flowering plants 
and measurably so as regards the higher algæ.. The lichens, 
fungi, diatoms, etc., I have not o to identify and they are 
therefore omitted. 
The island as it now appears is absolutely treeless and Sois 
shrubless, and it is scantily covered with pasture grasses which 
furnish subsistence to flocks of sheep. Altogether it is about as 
_ barren looking a pile of rock and stone as one could well imagine. 
When Penikese was first known it was covered with a growth 
_ of trees said to'be similar to those now found on Martha’s Vineyard 
and Naushon. -Among these may be mentioned the red cedar, 
pitch pine, red maple, shag atk; shad, poplar birch, hornbeam 
and two or three species of sumach. Of this growth there is now 
No trace left save the rotten roots of a solitary beech stump and a 
_ few branches of red cedar and red maple (?) found buried in the 
a small swamp.
