Senecio vulgaris L. 
The common groundsel is sometimes a troublesome weed in 
gardens. It begins to flower early in the spring and in wet 
Seasons successive crops spring up and continue the production 
of seed till cold weather stops their growth. In poor soil it will _ 
flower when but two or three inches high, in rich soil it may grow — 
12 inches high and bear many branches. It grows rapidly and 
requires but a few days in which to develop from seed to maturity. 
The soil sometimes becomes so filled with its seeds that as fast 
as one crop of the plants is destroyed another takes its place. 
Sisymbrium altissimum L. 
The tall sisymbrium is an introduced plant which has proved 
to be quite troublesome as a weed in some of the northwestern 
states. The past summer it appeared in the vicinity of Albany. 
It was probably brought here either from the north or the west 
where it has become firmly established. By destroying such 
troublesome weeds when they first appear much future labor and 
trouble may be saved. 
Solidago canadensis glabrata Porter 
Generally the early goldenrod, Solidago juncea, is the 
first species to blossom in our latitude. It begins to flower in July, 
The past season, which is notable for its peculiar influence on 
some plants, seems to have hastened.the time of flowering of some 
species. On July 24, S.juncea, S. canadensis glab- 
rata, S. arguta and S. rugosa were all found growing 
near each other at North Creek and ail were nicely in flower. The 
glabrate Canada goldenrod is a northern variety and perhaps in 
its effort to meet the requirements of the short northern seasons 
it has acquired the habit of blooming early. 
Viola cucullata Ait. . 
In the cold bogs and wet places of the Adirondack region where 
this blue violet delights to grow, it is not unusual to find it with 
flowering scapes 6-9 inches long. The flowers much surpass the 
leaves, often standing twice as high. Such specimens were col-
