156 Rhodora [Jury 
material representing the Clementon station, however, consists of two 
plants on the sheet, and both are of the same form. 
A suggestive point, however, comes out when the distribution and 
habitat of the typical form, and of the variety, in the Philadelphia 
region, is looked into. All our typical S. Smithit comes, so far as I 
know, from the immediate shores of the main course of the Delaware 
River, commonly within tide-water limits, and frequently submerged 
at high-water; while the three stations for the variety are a considerable 
distance back from the river,— in the case of Clementon about eleven 
miles — and naturally have a habitat distinctly different, the Clemen- 
ton station being a fresh-water pond. This may all be coincidence, 
however, but it would seem to show that there are interesting points 
still to be solved concerning the distribution and habitat of species and 
varieties of this class.

TETRAPLODON AUSTRALIS IN Massacauserrs.— While collecting 
lichens near a small pond in the vicinity of North Brookfield, Mass., 
in June, 1908, I found in the sphagnum near the edge of the pond, a 
moss which I did not recognize. Later this proved to be Tetraplodon 
australis Sull. & Lesq. So faras I know this moss has not before been 
reported from Massachusetts, possibly not from New England.—

NOTE ON SCHEUCHZERIA PALUSTRIS L.— The records in the hands 
of the Local Flora Committee show that this is a rare plant in the Bos- 
ton District — partly from lack of mossy peat-bogs, perhaps. I found 
a good station for this species in Sharon, Massachusetts, June 27, 
1909. Back of Billings Pond is a smaller pond surrounded by woods, 
but with a wide margin of peat-moss. In this moss was the Scheuch- 
zeria, along with such other bog-lovers as Decodon verticillatus (L.) 
Ell., Andromeda glaucophylla Link., and Gaylussacia dumosa (Andr.) 
T. & G. The last was still in blossom, but the Scheuchzeria was 
already well fruited. This record was accidentally omitted from the 
list. — C. H. KNowrrow, for the Local Flora Committee.
