1915] Beal,— Weeds growing in Amherst 29 
from those of M. uniflora (in European material of which they measure 
from 1.8-3.1 mm. in length). Nor are the larger fruits ascribed to 
M. reticulata shown by the specimens examined, for these have cap- 
sules only 6-6.5 mm. in diameter, smaller than the minimum given 
by Rydberg for M. uniflora. Furthermore the reticulated venation 
so apparent in M. reticulata is by no means confined to it, but occurs 
frequently in specimens from both Europe and America which can 
only be referred to M. uniflora. Since M. reticulata can only be 
distinguished from M. uniflora by its more ovate less orbicular acute or 
acutish leaves serrate-dentate rather than crenate, characters by no 
means constant, the plant seems better treated as a variety than as a 
species. I have seen specimens (in the British Museum) of M. 
uniflora (L.) Gray var. reticulata (Nutt.) Blake from the following 
localities: ALASKA: Sitka, Bongard; British CorvuMBIA: Banks 
Island, Menzies; Observatory Inlet, Scouler 52; Vancouver Island, 
district of Renfrew, 1902, Rosendahl 876; near Emerald Lake, alt. 
1336 m., 1904, Heacock (Shaw 87a); Roger Pass, alt. 1372 m., 1904, 
J. Macmillan (Shaw 476); Howser Lake, alt. 762 m., 19 June 1905, 
Shaw 724a; WasHINGTON: upper valley of the Nesqually, Cascade 
Mts., 16 June 1894, O. D. Allen 67; OREGON: dark woods of the 
Columbia, Nuttall (Types); CALIFORNIA: near Mt. Shasta, July,

WEEDS GROWING IN AMHERST. 
W. J. BEAL. 
THREE years ago I bought a little over an acre of land from the back 
end of the Brigham Farm fronting on the north side of Amity Street. 
Later Sunset Avenue was extended along the front on the east of the 
lot referred to. I built a house and seeded to grass the east half and 
occupied the house during the years 1913 and 1914. 
In this time I have identified one hundred and nineteen species of 
weeds growing in the lawn, and on extending my search for about a 
block beyond this area I have added eleven others, making one hundred 
and thirty in all.
