development of the plant was apparently due to the discouraging 
conditions under which it grew, for the 7: maritima above tide-limit 
grew tall and with the elongate racemes ordinarily expected in that 
plant. 
That the remarkable reduction of carpels in the periodically 
refrigerated plant was in any way due to its unfavorable habitat is 
not so clear, for under similarly adverse conditions, at the mouth of 
the Téte-a-Gouche River, in Gloucester County, New Brunswick, 
Triglochin maritima with the normal 6 carpels was later found by Mr. 
Williams and the writer fruiting when only 3 to 6 cm. high, while in 
warmer parts of the marsh tall plants often had only 5 carpels; and 
a sheet in the Gray Herbarium shows a specimen of characteristic 
T. maritima 6 dm. high, collected by David Lyall on the Kootenai 
River in Idaho or British Columbia, with only 3 carpels. It seems 
probable, then, that under ordinary circumstances the number of 
carpels in Z. maritima may vary from 3 to 6, and that this variation 
is unaccompanied by concomitant differences in size or habit of the 
plant. 
The Annual Meeting and Field Day of the Jossetyn BOTANICAL 
SOCIETY OF MAINE will be held at Skowhegan, June 29th to July 3rd, 
1903. For detailed information, apply to Miss D. H. Mou tron,
