CERAMIUM CLAVULATUM Ag. A well developed, not much branched 
form.! 
The five species starred above are additions to Dr. Howe's list for 
Peru. I much regret not being able to learn any more about the 
collector, nor as to whether any other specimens of her collecting are 
in existence. The character of these specimens is far above the 
standard of the ordinary "moss collector." "There are two species 
of Gigartina, each represented by a single specimen in full cystocarpic 
fruit; a single specimen of Gracilaria, with both cystocarpic and 
tetrasporic plants; two specimens of the Plocamium, one cystocarpic, 
the other tetrasporic. Very few collectings average as well as does 
this, for the scientific usefulness of the specimens. 
In conclusion, my thanks are due to Prof. Chrysler for the oppor- 
tunity to re-examine the specimens; to Dr. Howe for his examination 
of them and his notes; and to all who have helped me in the search 
for information as to the collector.

TWO VARIATIONS OF SILENE ANTIRRHINA. 
M. L. FERNALD. 
SILENE ANTIRRHINA L., forma Deaneana, n. f., internodiis non 
glutinosis.— Occasional throughout the range of the species. TYPE: 
recently cleared land near Winter Pond, Winchester, Massachusetts, 
June 22, 1913, Fernald & Long, no. 9494 (herb. New England Botani- 
cal Club). 
This form, discussed in some detail by Mr. Walter Deane in Rao- 
DORA, xii. 129-131 (1910), is so constant in the colonies where it occurs 
that it merits some designation; but differing from the typical form 
of the species only in the absence of the glutinous band found on some 
of the upper internodes in true S. antirrhina and apparently not hav- 
!In this connection I would note that an authentic specimen of Ceramium 
miniatum Suhr in my possession shows that the Peruvian plant mentioned by Howe, 
p. 157, is different; Dr. Howe agrees with me as to this, and expects to take up the 
matter later.
