84 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
* PETROSELINUM HORTENSE Hoffm. 
A weed in a garden, 1897, Mrs. Nellie F. Flynn. Possibly merely 
persistent after cultivation. A specimen received from Mrs. 
Flynn was collected Aug. 16, bearing mature fruit. 
* CICUTA MACULATA L. 
Capaum Pond, May 30, 1909, a single tuft 14 inches high on 
the west side of the pond back of the beach. Not seen since. 
Met with at two localities on Marthas Vineyard. 
* CICUTA BULBIFERA L. 
Mrs. Nellie F. Flynn has sent me for examination a specimen 
of this species collected Aug. 18, 1899, in a ditch near Shawauk- 
emmo spring. It is a stout plant, 8.5 dm. tall, in full flower and 
bearing many clusters of young bulblets. Mrs. Flynn has now 
no recollection of having seen more than this one plant, the only 
one known ever to have been collected on Nantucket. 
SIUM CICUTAEFOLIUM Schrank. 
Common about the borders of fresh water ponds and in swamps 
and ditches. The leaves are well developed at the end of May. 
First flowers July 11, 1912. 
PTILIMNIUM CAPILLACEUM (Michx.) Raf. 
Abundant in damp places in either fresh or brackish soils. 
The seedling plants become visible early in June and are in full 
flower and fruit in September. 
* AETHUSA CynapPium L. 
Occasional about the wharves and by street sides in the town. 
On every visit to Nantucket I see it somewhere, but never more 
than a few plants, and usually at some new locality. Umbels 
showing white June 4, 1911; first flowers June 10, 1909; in full 
flower and fruit in September. 
* ANETHUM GRAVEOLENS L. 
Mrs. Flynn has sent me specimens of this plant collected by 
her from a large clump growing in a waste spot among the Scallop 
houses near the harbor shore.
