1923] Svenson,—Plant Notes from Squam Lake, N. H. 183 
In cultivation the flowering season of this showy plant, much like 
R. hispida, is prolonged. It has the same habit as hispida and becomes 
a symmetrical treelike shrub, 1.3 to 2 m. high. 
Robinia boyntonii Ashe,' as described, is an aggregate though the 
major part of the description was based upon a single and well known 
plant. The description of the fruit was drawn from an herbarium 
specimen which was later recognized as being different from the 
flowering plant. Groups of R. boyntonii examined for several years 
have not been known to produce fruit. It is probably one of the 
forms which does not produce fruit. 
Robinia longiloba Ashe? was described largely from a plant which 
is now in cultivation, but the description of the fruit was drawn from 
an herbarium specimen originally included in R. boyntonti. More 
recently living plants which agree in all particulars with this fruiting 
specimen have been located and are now in cultivation. These 
plants differ so strikingly from R. longiloba that they have been 
separated from it as R. pedunculata Ashe? in allusion to the elongated 
peduncles. In cultivation it fruits freely. R. longiloba, as cultivated, 
or in two groups of wild plants numbering several hundred stems, 
has not been known to fruit.

PLANT NOTES FROM SQUAM LAKE, NEW HAMPSHIRE. 
H. K. SvENSON. 
Squam LAKE lies in the foothills of the White Mountains, and is one 
of the group of lakes which extends from central New Hampshire 
to southwestern Maine. Its area is about fifteen square miles, in- 
cluding numerous coves, islands, and little bays. "These plant notes 
refer to a small area at the northwestern corner of the lake, in the 
town of Holderness, Grafton County, and were obtained during the 
summer of 1921 in connection with work at Camp Algonquin. Rattle- 
snake Mountain, a hill rising from the lake to the height of about 
thirteen hundred feet, is probably the most interesting single locality. 
Composed of a rapidly disintegrating granitic rock, it is marked by
