270 BICKNELL: FERNS AND 
*BIDENS FRONDOSA L. 
Frequent in low grounds and waste places about the town; 
sometimes on pond shores. In early flower at the end of August, 
1904; in full flower September 10, 1907. 
*BIDENS VULGATA Greene. 
Frequent in yards and waste places and by streetsides in the 
town; Shawkemo. Just in flower in early September, 1904; in 
full flower September 16, 1907. 
 *Galinsoga aristulata sp. nov. 
Galinsoga parviflora var. hispida DC. not G. hispida Benth. 
A few plants on Easton Street in full flower September 13, 
1907; Fair Street, September 19, 1914; specimen in herbarium of 
Miss Grace B. Gardner. 
This now widespread weed wherever I have met with it has 
not failed to prove itself always readily distinguishable from the 
true G. parviflora Cav., even without reference to the constant 
and pronounced differences in the pappus scales. Nevertheless 
I do not discover that it has ever received an available specific 
name. Insome European gardens of today it is evidently known as 
G. brachystephana Regel, since it has been grown at the New York 
Botanical Garden from seeds received from Europe under that 
name. There are before me specimens raised from such seeds 
that, noting their similarity to our plant known as G. parviflora 
var. hispida, 1 took from the herbaceous beds at the garden 
September 11, 1898. Although the close counterpart of these 
specimens has not been found in any example of our common weed 
met with since that time their divergencies, however obvious, are 
not greater than might well be expected to mark a long established 
garden form of so variable a plant. In any case, however, there need 
be no doubt that the name G. brachystephana in its use for this plant 
has been mistakenly applied. I have not been able to consult the 
rare pamphlet (Ind. Sem. Hort. Turic, 1846) that contains the orig- 
inal description of G. brachystephana, which species, if we may 5° 
understand its history, came from seeds received in Europe about 
the year 1846, from what country does not appear. Nor do I 
find any descriptive text in the different issues of that period of In-
