214 Rhodora [NOVEMBER 
The Zechia minor, var. racemulosa of Bennett’s Catalogue of Rhode 
Island Plants, appears to rest upon wrongly-named material. The 
Acer saccharinum, var. nigrum of the same list is probably an error. 
The Zechea major of Professor Jesup’s Catalogue of Plants of Han- 
over, N. H., proves to be Z. intermedia. 
Rhus Cotinus, L., is reported by Dame & Collins, Fl. Middlesex Co., 
as “ often found escaped ” in Middlesex county, Massachusetts. 
Aesculus Hippocastanum, L., the horse-chestnut, so commonly planted, 
has been reported in several local lists as “ escaped,” “ self-sown,” etc., 
but more exact data as to its persistence in a wild state are lacking. 
Similar reports could be made of Acer Psuedo-platanus, A. platanoides, 
and in fact many other plants of cultivation. 
Cardiospermum Halicacabum, L., has been found by Mr. C. E. 
Perkins as a casual plant on waste ground at Somerville, Massachu- 
setts. 
A form of Acer Saccharum, Marsh., resembling at least in the con- 
tour of the leaves, the var. darbatum of Trelease, has been found in 
Maine and southern New Hampshire by Mr. M. L. Fernald, but its 
genetic affinity to the thickish-leaved plant of Tennessee and Arkansas 
is at best doubtful. 
Polygala Nutallit, was reported by Mr. W. S. Harris ' as a character- 
istic plant in the flora of Windham, N. H., but the species on further 
examination proved, according to Mr. Harris, to be P. sanguinea. 
The record of Polygala brevifolia, Nutt., from Rhode Island rests 
upon a simple specimen collected long ago by Stephen T. Olney and now 
preserved in the herbarium of Brown University. 
Polygala polygama, var. abortiva, Chodat (Monogr. Polygal. 280), 
is a variety or perhaps rather a state in which the upper as well as the 
basal racemes bear chiefly or exclusively cleistogamous flowers. This 
plant is worthy of field study and probably has a much wider distribu- 
tion than is now known. 
The desiderata of the above lists which may be sought with greatest 
confidence of success are Hudsonia ericoides in southeastern New 
Hampshire, LE/atine americana in Vermont, and Rhus canadensis in 
northwestern Massachusetts.
