BICKNELL : FERNS AND-FLOWERING PLANTS OF NANTUCKET 61 
* ACTAEA RUBRA (Ait.) Willd. 
This woodland ‘species occurs along Rattlesnake Bank, where, 
in favorable seasons, it forms patches of luxuriant growth and fruits 
prolifically ; a small colony was found also in a dense thicket in 
Quaise and a single sterile plant in Polpis. Bearing green fruit 
June 11, 1909; fruit matured Aug. 7, 1906. 
* AQUILEGIA CANADENSIS L. 
Discovered in full flower June 2, 1909, near Acquidness Point, 
growing on a prominent knoll near the shore under a close 
thickety growth, mainly of bear oak, beach plum, and wild thorn 
(Crataegus). The colony consisted of perhaps thirty plants scat- 
tered over a space of about ten yards by three yards in general 
area. As this bright-flowered plant has never been reported from 
Nantucket it seems probable that it occurs at no other place on 
the island and, since the thicket which protects it is wholly isolated 
and almost surrounded by salt marshes, there is little chance of 
its ever being able to spread elsewhere. 
ANEMONE QUINQUEFOLIA L, 
Common in thickets and open low grounds. In full flower 
June I, 1909; a few flowers remaining June 9. 
* RANUNCULUS DELPHINIFOLIUS Torr. 
In Squam, near Wauwinet, Sept. 5, 1904, —a nearly dried-out 
pot-hole covered with a dense tangle of leafy runners, no flowers 
remaining ; a few plants in a similar situation about half a mile 
distant ; some young plants in a muddy pot-hole near Tristram 
Coffin’s Homestead, Sept. 12, 1907. 
RANUNCULUS oBTUsIUSCULUS Raf. 
In two small pools near the Orange Street railroad crossing, 
where it was long ago discovered by Judge J. R. Churchill and 
Mr. Walter Deane; also in a pool east of the Creeks. First 
leaves appearing May 30, 1909; in full flower in August and 
some flowers remaining at the middle of September. 
RanuncuLus Acris L. 
Abundant, conspicuously so when in full flower in the fields 
and meadows in and near the town. Generally in flower May 30, 
1909, but not yet at its height of bloom; few or no flowers left 
by the second week in September.
