Potamogeton marinus, é 
A little above Niagara Falls on the Canadian side. Rev. 
Thomas Morong. 
Habenaria fimbriata, Gray. 
One plant, with pure white flowers, deliciously fragrant, found 
at Point Abino, Ont. 1882. 
Epipactis Helleborine, var. viridens, Irm. 
Near Scajauquady’s Creek, Buffalo :—The second known sta- 
tion of the species on the American continent. Here first 
found by Miss Edza M. Porter, July, 1882. Equivalent, 
according to GRAY, to £. /atifolia. The plant answers ex- 
ceedingly well to the following generic description of Z/z- 
pactis, (transcribed from Warson’s Botany of California), 
except as noticed in our specific description below. 
‘“EPIPACTIS, Haller. 
3 ‘ 
‘‘ Perianth spreading, the sepals and petals nearly equal; 

‘lip free, deeply concave at the base, without callosities, nar- 
‘‘rowly constricted and somewhat jointed in the middle, the 
‘“ upper portion dilated and petaloid. Column short (equal- 
‘‘ing the anther). Anther sessile behind the broad, truncate 
‘stigma, on a slender jointed base, two celled, obtuse ; pol- 
‘‘len masses coarsely granular, becoming attached above to 
‘“the gland capping the small rounded beak of the stigma. 
‘‘Caulescent and leafy from creeping rootstocks; flowers 
‘few and pedicelled, rather large in our species, |Z. gigantea, 
‘‘Dougl.], with conspicuous bracts, divergent, and the 
‘‘ ovaries at right angles to the stem.” 
E,. Helleborine, Irm. Rootstocks not creeping. Stems, 
one to several. Height from twelve to twenty-four inches. 
Leaves broadly ovate, two to three inches long, pointed, 
plicate. Raceme, before flowering, recurved, pubescent. 
Flowers numerous (from thirty to fifty), in color varying from 
a light, greenish yellow to a dark, dull purple. The spoon- 
shaped lip very dark, covered with a viscid secretion. Ova- 
vies, as they approach maturity, reflexed. July and August. 
In our station certainly indigenous. About 200 individ- 
uals were counted, all growing within the space of a few 
hundred feet along a northerly hillside, from five to thirty feet 
above the creek. The diversity of color, which the flowers 
on different plants display, indicates that the variety, v777- 
dens, has no stability of character.
