56 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
AIZOACEAE 
MoLiuGo VERTICILLATA L, 
Very common, especially so on sandy levels about some of 
the south shore ponds. In full flower in August and September. 
Nothing was seen of it in June although in the same latitude it 
commonly begins to flower before the end of May. 
PORTULACACEAE 
PoRTULACA OLERACEA L. 
Frequent in cultivated fields and occasionally elsewhere ; 
apparently nowhere common. Noticed in flower as late as 
September. 
* PoRTULACA GRANDIFLORA Hooker. 
Along aneglected roadway at Siasconset in September, 1899, 
in full flower; not observed since. 
ILLECEBRACEAE 
SCLERANTHUS ANNUUS L. 
Abundant in sterile soil, doubtless flowering at all seasons. 
CARYOPHYLLACEAE 
AGrostemMMA GitHaco L. 
Apparently uncommon. Mrs. Owen mentions it as seen 
occasionally in fields. I observed it only once, on June 9, 1908, 
not yet in flower-bud. In midsummer its conspicuous flowers 
might well show it to be more common. 
SILENE VULGARIS (Moench) Garcke. 
Observed at four places, by street-sides and in waste spots in 
the town, and also in an old field on the Benjamin Coffin farm. 
In fresh flower June 9, 1908 ; still in bloom Sept. 10, 1904. 
* SILENE ANTIRRHINA L, 
A scattered group of very small plants on a bank near Acquid- 
ness Point, June 2, 1909, the flower buds just appearing. 
SILENE ARMERIA L, 
An occasional garden escape into waste ground, not observed, 
however, since August, 1906.
