There are also three more lichens, all collected under the 
number 1521. at Cumberland Uav, December i, i()i_', of which 
Dr. H. E. Masse, in a letter to Dr. R. H. Howe, Jr., says 
"Caloplaca callopisiiia ( Ach. 1 Th. Kr., Biicllia sa.vafilis

in the books: and Caloplaca unironnii (Hoffm.) Th. Fr. var.

Dr. Skottsberg. in his paper on the vegetation of South 
Georgia, which forms ])art of the reports of the Swedish South 
Polar Expedition, has applied the methods of Raunkiaer in 
studying the relation l)etween the climate and the plants of the 
island. Wv grouping the s]iecies according to Raunkiaer's so- 
called "Crowth Forms," an c.v f^osf facto method of determin- 
ing climate from the amount and kind of Inid ])rotection exhib- 
ited by the plants during winter, he gets some interesting sta 
tistics. Of cJiamccphytcs (])lants perennating on the surface i>f 
the ground and thus ])rotected b\- the snow ])Ianket ) there are 
47/(: ; of hcmicr\[^topIi\'tcs ( plants having dormant buds in the 
upper crust of the soil ) , there are 40'^' ; cryptopliytcs ( plants 
with dormant parts subterranean ), 7'' ; tlicrophxtcs (annuals), 
7%. These figures are based, of course, on the species of the 
island and not on the indixidual^, and to this extent the results 
are fatilty, as an\- method of correlating climate and vegeta- 
tion must be. For instance, the three most widely distributed 
and most frequent phanerogams, Fcstiica crccfa, Foa Habcllata 
and Acacna adscciidciis are all channvpliyfcs and would verv 
seriously upset the above jiercentages if an individttal census 
were the basis of calculation. The figures are of chief interest 
as related to similar figures for other regions, a. comparison 
which lies outside the scope of this paper. 
The expedition made a brief stop at Ca])e \"erde Island-, 
where Mr. Murphy picked u]) Zy;^ophylluiii si'iif^lcx L. ( Xo. 
1517) and Jciiaii :'ir;^aftim I... l)oth collected at St. \"ineent.
