had now largely disappeared. Both at this time and at the earlier 
visit on June 4 no examples of the Peridermium were found more than 
3 dm. above the ground, and the infection was mostly on very small 
trees, or on small branches near the ground. 
The three previous collections of this Peridermium were also on small 
branches. 'Two of them were made by Mr. J. B. Ellis at Newfield, 
N. J., one in 1882 on Pinus virginiana Mill., distributed in his N. 
Am. Fungi no. 1021, and the other in 1890 on P. rigida Mill. "The 
third collection has little import, as it was made in the Missouri Botani- 
cal Garden, and if it really belongs to this species, was doubtless 
brought to the Garden on plants obtained in the eastern states. ‘The 
rust on Comptonia is common in the region about Newfield, N. J. 
Of the common forms of Aecidiwm and Roestelia many have been 
definitely associated with their corresponding telial forms. But of 
the twenty-seven known species of Peridermium in North America, 
which number doubtless represents not more than half the full number 
that exists, only three have yet been connected by cultures with their 
telial forms, hence one element of interest in the observations of Dr. 
Thom. The publication of this note is intended to supply the clue to 
any one who may be fortunately situated, and inclined to undertake 
cultures of this rust, which can best be made during the month of May.

Tue RECORD or COLOR VARIETIES OF GRATIOLA AT WESTFIELD, 
A CLERICAL Ennon.— On page 123 of the current volume of RHODORA 
it was stated that the white and light yellow forms of Gratiola aurea 
had been found at Westfield, Massachusetts. Miss Emily F. Fletcher 
has called our attention to the fact that this was probably a clerical 
error and that the station where the plants were found was in reality 
Westford, which is in Middlesex County, and not Westfield as stated. 
Reference to Dame & Collins’s Flora of Middlesex County, Massa- 
chusetts, shows that Miss Fletcher is quite right and that in fact the 
station was Westford and not Westfield as quoted through some over- 
sight.— Ep.
