Pithophora Kewensis. W. G. DeWitt. (Journ. N. Y. Micros. 
Soci, pe 218;) 
This Alga, originally discovered in the Water Lily tank at 
Kew Gardens, was supposed by Wittrock to have been an im- 
portation from Brazil, but Mr. A. D. Balen has found it in several 
places near Plainfield, New Jersey, so its distribution is not alone 
tropical. Mr. DeWitt states that it grows well in his aquarium, 
where it has fruited during the past two months. 
Quercus prinoides, Willd. Thomas Meehan. (Proc. Acad. Nat. 
Sci. Phil., 1885, p. 365.) 
Mr. Meehan exhibited a series of fruiting branches of this 
oak, showing remarkable variation in leaf-forms, which in some 
were orbicular, in others lanceolate; some had lobed and wavy 
margins, while others were quite entire. The plants all grew 
within a few feet of each other.

since devised.
