62 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
The later leaves, as well as those which are produced by a 
second growth following the mowing of the fields or other injury, 
are usually less deeply and narrowly cleft than those of the spring 
and early summer and have broader segments [var. Stevent 
(Andrz.) Lange]. This is the common state of the plant in the 
autumn, but, in its extreme form, is scarcely to be found in the 
spring, when the typical state of the plant prevails. 
RANUNCULUS BULBOSUS L, 
Common throughout, preferring a drier, poorer soil than X. acris, 
and much less noticeable in the late summer and autumn, the 
branching parts appearing to wither earlier in the season. In full 
flower May 30, 1909; no flowers remaining by September. 
RANUNCULUS REPENS L, 
In luxuriant abundance everywhere in low meadows and springy 
places in the neighborhood of the town and often growing about 
yards and along street-sides ; sometimes in out of the way bogs. 
In full flower May 30, 1909; a few flowers may be found as late 
as the middle of September. 
OxyGRAPHIS CyMBALARIA (Pursh) Prantl. 
Common on damp sandy levels about some of the south shore 
ponds; Capaum Pond; salt marshes along the Creeks ; Polpis 
Harbor. First flowers June 8, 1909; some flowers as late as the 
middle of September. 
* THALICTRUM REVOLUTUM DC, 
Rattlesnake Bank, not abundant, but growing with great vigor, 
some plants becoming nearly eight feet tall; Watt’s Run Bank; 
thicket by shore pond east of Pocomo Head. Panicles well devel- 
oped but not yet in flower June 11, 1908; well fruited Aug. 7, 
1906. 
THALICTRUM POLYGAMUM Mulhl. 
Mrs. Owen's catalogue records, on the authority of Mr. Dame, 
‘‘a few depauperate specimens in swamps in Squam.” 
Note.— The barberry (Berderis vulgaris L.) is admitted to Mrs. 
Owen’s catalogue upon the occurrence of a single plant found by 
Mr. Dame by the roadside near Siasconset. This was doubtless 
only a transient waif.
