A word remains to be said of the degree of completeness with 
which the flora of Nantucket is now probably known. The 
botany of many another region of even greater extent might be 
very thoroughly chronicled from far less investigation than has 
been bestowed on Nantucket. Here, as we have seen, are found 
conditions that ask for close work by the explorer and notwith- 
standing what has already been accomplished the island today 
remains a broad and an inviting botanical field. I do not in the 
least doubt that a systematic exploration continued through an 
entire season would bring to light many unexpected things and 
add materially to the list of Nantucket plants. Many a bog, or 
shrubby patch, or little space of open hillside or plain is alone the 
home of some noteworthy Nantucket species, and the difficult 
thickets, especially, cannot yet have yielded all their secrets. 
When we recall how easily, out of their particular season, many 
plants may miss the eye, and that there is already a long list 
of Nantucket species, each one having its single spot somewhere in 
the fifty square miles that make up the island’s area, the possibili- 
ties of new discoveries may well stir the later explorer with some- 
thing of the enthusiasm which animated those who were pioneers. 
I should suppose that it were well within the possibilities that 
IO per cent or more of the native flora remained to be brought to 
light, and that an addition of not less than 5 per cent to the 
number of plants already known might be confidently looked for. 
y own visits to the island have been never for more than brief 
periods and have wholly missed the important seasons of mid- 
summer in the last weeks of July and of August. Nor have I col- 
lected on Nantucket in mid-August since 1904, nor in the autumn 
since 1907, nor explored there at all since 1912. It may be further
