Potamogeton marinus, 



A little above Niagara Falls on the Canadian side. Rev. 

 Thomas Moron.;. 



Habenana fimbriata, Gray. 



One plant, with pure white flowers, deliriously fragrant, found 

 al Poinl Vbino, Ont. 1882. 



Epipactis Helleborine, var. viridens, Inn. 



Neai Scajauquady's Creek, Buffalo: — The second known sta- 

 tion of the species on the American continent. Here first 

 found by Miss Edna M. Porter, July, 1882. Equivalent, 

 according to Gray, to£. latifolia. The plant answers ex- 

 ceedingly well to the following generic description of Epi- 

 pactis, (transcribed from Watson's Botany of California), 

 pi as noticed in our specific description below. 

 " EPIPACTIS, Haller. 

 " 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, [£. gigantea, 

 " Dough], 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 Jiffy), in color varying from 

 a light, greenish yellow to a dark, dull purple. The spoon- 

 shaped lip very dark, covered with a viscid secretion. Ofa- 

 ries, 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, viri- 

 dens, has no stability of character.
