Figure 9. In this filament no conjugation was discovered 
in any part of it, but the cells a and b have each sent out a tube 
at their adjoining ends, as ¢ and dare also beginning to do, while 
ce has sent out an additional tube at the other end. 
Figure 10 is doubtless a later stage of the last, the two tubes 
together conjugating with a third and lower cell. ‘ 
Figure 11 is another phase of polygamous conjugation, while 
Figure 12 shows strong inclinations in that direction. 
GENERAL NOTES. 
Acer pseudo-platanus is a common shade-tree about our streets. The 
fruit is now forming and in every raceme I find one or more of the samaras 
composed of three or four carpels, instead of the normal number, two. 
Catalogue of New Brunswick Plants.—We are indebted to Mr. George 
U. Hay, of Carleton, N. B., for the Bulletin of the Natural History Society 
New Brunswick, No. 1v. This contains “ A preliminary list of the plants of 
New Brunswick,” by Prof. James Fowler, M.A. The Rey. Mr. Fowler was for 
a long time a resident of New Brunswick, and has been the most active col- 
lector of the region. He now resides at Kingston, Ontario. We are surp i 
to find how recently botanical observation began in this province, and feel ” 
if we could almost rank ourselves among the early collectors. The earliest 
published information dates back only to 1862, and in 1864 the writer collected 
largely about Fredericton, St. Stephen, and Campo Bello, continuing bis bina 
in the years 1866, 1868 and 1872. Unfortunately he has preserved very little 
material from those explorations. To return to Mr. Fowler’s list, it is an & 
tremely interesting one in many ways; its author was indefatigable in his re- 
searches. He has found some curious cases of extra-limital distribution. Fe 
instance at Eel River, Restigouche County, Collomia linearis occurs. “ If it 
not native, it is at least thoroughly naturalized.” Mr. G. F. Mathew, of & 
John, has elsewhere pointed out how the river St. John affects the distributio 
of plants. Indeed, the whole district is well worth further study. There #¢ 
rich collecting grounds already familiar, like the marshes of the Kennebeck- 
osis, but the flora of much the larger part of the province remains practic lly 
unknown. The members of th geological survey record what they find, but ‘ ir 
attention is too much engaged upon other work to allow careful exploration: 
Not the least interesting part of the list is the appended catalogue of ballast 
plants gathered around St, John, Portland, etc. The list is well edited and 
printed, and will repay careful perusal. 
Utricularia cornuta.—On Decoration Day it has been my habit eye 
long time to take an excursion in the woods. This year I was — ie

seeing a most magnificent display of Utricularia cornuta, a mass of yel
