Report of the State Botanist.
Galium pilosum Ait.
A small form six to nine inches high, with short internodes,
leaves about half an inch long and flowers crowded in small
dense chisters was collected on the north slope of Skylight
mountain, one of the Adirondacks. It might be called variety
parvum.
Galium circsezans Mx. var, glabrum Britton.
Leaves and stems nearly glabrous ; corolla glabrous. "White-
hall, New Scotland and Sandlake. July.
Solidago bicolor L.
A branching form, both of this and its variety concolor, is
quite common. Each branch is terminated by a spike-like
panicle of flowers.
Solidago humilis Pitrsh.
Top of Bald mountain, near Third lake, Herkimer county.
Four distinct forms of this species occur in this limited station.
First, a very leafy dwarf form, four to six inches high with a
short dense panicle one to two inches long. Second, a very
leafy form eight to twelve inches high, with an oblong leafy
interrupted but dense panicle. The margins of the lower leaves
are often wavy toward the base. These forms make a very close
approach to the Western var. nana. Third, a still taller form
in which the stem is less leafy, the leaves are smaller, more narrow
and scattered, and the panicle is elongated, narrow and
spike-like, but commonly interrupted either in its entire length
or toward the base only. This is one to two feet high. The
upper leaves are entire, the lower and radical ones more or less
bluntly serrate. The stem is either green or purple and is gla-
brous below. This is the most abundant form. The fourth
form is like this in all respects except that it has a broader, more
branched panicle The panicles in all the forms are so glutinous
that they adhere to the drying papers when placed in press.
It is a little remarkable that this species should exhibit such
a variety of forms in such a limited locality. All the forms
appeared to be growing under the same conditions of soil, tem-
perature, moisture and exposure. I suspect this is the plant
which in Paine's Catalogue is referred to Solidago speciosa var.
angustata. It is separable from that species by its glutinous
