1911] Hall and Massey,— Plants in Flower 91 
of Natural History. Friday evening, Feb. 24, Prof. K. M. Wiegand 
spoke on Character in Winter Buds, illustrating his talk with speci- 
mens of various twigs. Prof. J. F. Collins spoke of the six species and 
two varieties of Polytrichum known in Maine. Dr. L. W. Riddle 
described lichens, and talked of their distribution in Maine. The 
State furnishes a large field, in which comparatively few extensive 
collections of lichens have been made. 
Saturday morning, Feb. 25, the society took a three-mile walk on 
Cape Elizabeth. Among the species noted were Prunus maritima 
Wang., Cynanchum nigrum (L.) Pers., true Eupatorium. purpureum 
L. (new to Maine), an interesting Carya, and the prostrate shore form 
of Juniperus virginiana L. Dr. Riddle collected about 30 lichens, 
the most interesting of which were the coastal Cladonia reticulata 
(Russell) Wainio, and the southern Usnea trichodea Ach. 
Saturday afternoon Prof. M. L. Fernald showed specimens and 
described many recent additions to the Maine flora. Mr. C. H. 
Knowlton talked about the boreal flora of the Washington county 
coast, showing numerous specimens classified by habitats as woods 
plants, beach and marsh plants, species of the rocky headlands and 
of the peat bogs. 
Eight new members were elected to the society. The summer 
meeting will be held at Brunswick, Aug. 22-25. C. H. KNOWLTON, 
Hingham, Massachusetts. 
PLANTS IN FLOWER FEBRUARY 8, 1911, AT CLEMSON COLLEGE, 
SouTH CAROLINA.— Upon various collecting trips about Clemson 
College, South Carolina, about thirty miles from the main range of 
the Blue Ridge Mountains, in the western part of the state, the follow- 
ing plants were collected in flower upon the above date: Acer rubrum, 
Alnus rugosa, Arabis virginica, Capsella Bursa-pastoris, Hepatica 
triloba, Lamium amplexicaule, Prunus Persica, and Stellaria media. 
All of these with the exception of maple and peach have been in 
full flower for three weeks and more, and besides those mentioned there 
is a large number of exotic plants in flower out of doors. 
A more interesting observation than these, in all probability, is 
the occurrence of Hepatica, which grows only upon the northern or 
cooler slopes of the hillsides here, in flower upon November 12, 1910 
in this neighborhood. Of course the season for January here was much
