BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 73 
TRIFOLIUM PROCUMBENS L. 
Gravelly and sandy fields and dry grassy slopes, mainly in the 
more settled parts of the island, usually growing in close beds or 
smaller isolated patches. Very common in the neighborhood of 
the town and from Reed Pond to the county fair grounds, extend- 
ing as far east as Shawkemo; common in Madequet and about 
Siasconset. First flowers May 30, 1909; just in flower June 7, 
1911; blooming abundantly during June. Some flowers Sept. 16, 
1907. 
*TRIFOLIUM DUBIUM Sibth. 
Roadsides, fields, and grassy places. Abundant throughout 
the north side of the island from Madequet to Squam; abundant 
also in the southwest quarter and about Siasconset. Apparently 
beginning to bloom rather earlier than T. procumbens and having a 
briefer flowering period. First flowers May 30, 1909; much of it 
past flowering June 18, 1908, and June 26, 1910. Mr. Floyd’s 
notes contain a reference to this species on Nantucket as far back 
as 1889, when it was collected by Miss Elizabeth S. Kite. 
*“TRIFOLIUM INCARNATUM L. 
Occasional in old fields, persisting where it has been sown, but 
apparently never becoming permanently established. Siasconset 
1899. In full flower May 30, 1909, and late in September. North 
Beach Street—meadow—evidently introduced in grass seed, 1895, 
FP. G. Floyd; yard in town, 1896, Mrs. Mabel P. Robinson, fide 
F. G. Floyd. 
TRIFOLIUM ARVENSE L. 
Abundant in dry sterile soils. When almost in flower it often 
remains a long time without coming actually into bloom. Appear- 
ing to be in flower June 15, 1910, but no flowers fully opened until 
June 27. In September many young plants often come into bloom 
among others that had completely dried up long before. 
TRIFOLIUM PRATENSE L. 
Very common. In early June it is conspicuous from its 
luxuriance and profuse bloom in low-lying grassy lots in the town. 
First flowers May 30, 1909. 
Trirotium uysripum L. ) 
Common in and about the town; less frequent at more distant
