Two, Delphinium Consolida and Viola tricolor, were manifestly garden 
escapes. My own list covers Eastham only, about seven square miles. 
His list covers a much greater area in a more fertile region; as a slight 
offset may be reckoned that the climate at Eastham is milder than 
that at Boston; in the autumn of 1914 the Dahlias here were in ex- 
cellent condition after those at Boston, and even on the Buzzard’s 
Bay shore of the Cape, were destroyed by the frost. In the list I have 
put a star (*) at the left of the name in each case where a species 
reported by him is not to be expected in my region, and a dagger (1) 
to indicate the reverse. Of these species, it will be seen, there are 
twenty and two respectively. This leaves seventy species that 
might be expected in both regions; of these he found twenty-one 
that I did not, I found eighteen that he did not; thirty-one species 
we both found, a sufficiently large proportion, it seems to me, to show 
that certain species have the capacity to continue flowering as long as 
weather conditions permit, while others, whose flowering season begins 
no earlier, have a definite time for getting through, with little regard 
to conditions of temperature. No grasses were included in Mr. 
Torrey’s list and I do not know whether he noticed grasses. I found 
three species, one native and two introduced; Spartina patens, Bromus 
tectorum and B. hordeaceus were in flower in Eastham in November, 
1914. 
That these lists are by no means complete may be judged from the 
fact that in going over my “bicycle” list, referred to above, I find that 
I noticed three species that do not appear in the table I have given; 
Trifolium arvense, Cichorium Intybus and Artemisia caudata. If lists 
could be made out for other localities, a comparison might lead to 
definite conclusions; it is to be hoped that the opportunity may come 
to some readers of RHopora, and be improved by them.
