56 THIRTY-FOURTH ANNUAL REPORT OF THE 
occur in Lower Saranac lake. In this lake are,also P. amplifolius, 
P. Claytonii, P. gramineus, P. hybrideus, P. compressus, P. perfolia- 
tus and P. natans. In the inlet between this lake and Round lake, P. 
amplifolius, P. Claytonvi and P. gramineus v. heterophyllus abound in 
a luxuriant growth. Pond-weeds, water-lilies and aquatic plants gene- 
rally are more abundant in and near the inlets of the lakes of this re- 
gion than in other parts of the waters. Probably the sediment brought 
down by the streams and accumulating in the parts of the lakes adja- 
cent to their inlets affords a soil especially favorable to the production 
and support of water-plants. 
Trillium erectum vy. declinatum, Gr. Long Island. Coles. Some 
of the flowers are white, others are variously tinged with pink. In one 
specimen two flowering stems grew from the same rootstock. 
Lilium Philadelphicum, Z. This commonly has but one or two 
flowers on a stem, but in rare instances as many as five flowers occur. 
Carex flava, Z. A large form with three or four fertile spikes and 
the staminate spike, nearly all fertile, was collected at Millerton. The 
numerous large fertile spikes give the plant an unusual appearance. 
Sometimes the lowest spike is compound. 
Carex triceps, Mz. A form with oblong spikes. Mt. Defiance. 
Carex gynandra, Schw. Not rare in the Adirondack region, but 
passing into C. crinita by such insensible gradations that it is difficult 
to keep them separate. 
Carex scoparia, Schk. Of this species we have three forms. In one, 
the spikes are arranged in a somewhat racemose manner. This is 
usually found in dry, sandy soil. In another the spikes are more 
or less aggregate in a cluster or head. This is the common form 
usually found in wet places. In the third form, the var. minor, the 
spikes are small and aggregate. This occurs in the Adirondack moun- 
tains. ‘The whole plant is smaller than usual. 
Carex debilis, Mz. A large, thrifty form is found in the Adirondack 
region. It hag five fertile spikes, the lowest one usually bearing near 
its base a branch about an inch in length. 
Carex tentaculata, M/uhi. At Edmonds ponds starved specimens 
occur which have but a single short subglobose fertile spike. They 
were in company with var. gracilis. 
Carex oligosperma, Mz. Stony ponds. A slender form with the 
fertile spikes but three or four-flowered. 
Agrostis scabra, Willd. In thin woods in the Catskills there is asmall 
leafy form of this grass with green panicles. 
Muhlenbergia Mexicana, Trin. A very variable grass. A tall,slen- 
der, slightly branched variety was found on damp shaded cliffs in Stony 
Clove. A much branched form with short erect leaves and a rigid 
aspect occurs on the banks of the Hudson near Albany. Growing with 
it and scarcely to be distinguished from it, except by the awned flowers, 
is a very similar form of Muhlenbergia sylvatica. 
Glyceria fluitans, &. Br. Edmonds ponds. In this locality the 
spikelets are short, three to four lines long, and usually about five- 
flowered. 
Setaria viridis, Beawv. A singular form was found at West Albany 
on the banks of the railroad, ‘he spikes are more slender than usual,
