REVISION OF EPILOBIUM. 89 
New Brunswick to Alaska and the northwestern islands, south 
to lower Canada, the mountains of Colorado, and Washing- 
ton; also in Europe and Asia, extending into India: —a 
boreal plant, so far as our continent is concerned. — Speci- 
mens examined from many parts of Canada and British 
America, Alaska, Bering Straits, Washington (Suksdorf, 
1881, as EZ. coloratum), and Colorado. — Plate 13. 
Forma Eabradorica, Hausskn. — A span or two high; 
leaves oblong-lanceolate to broadly lanceolate, more diver- 
gent; flowers solitary or few, very nodding. — Monogr. 
131.— Wet places and bogs, Labrador to the White 
Mountains of New Hampshire, in the former locality, es- 
pecially, passing into the usual western form. — Plate 13. 
E. anagallidifolium, so far as the Eastern States are 
concerned, seems to rest upon this form, which in a dwarfed 
state considerably resembles it, but may always be recog- 
nized by its revolute leaves, very cinereous inflorescence, 
long, papillate seeds, and (when obtainable) filiform bulb- 
iferous shoots. 
+ + Innovations unknown: habit of Z. palustre, but the leaves more 
alternate, sparingly toothed, and not revolute: seeds obovoid, beakless, 
slightly papillate. 
E. PsEUDO-LINEARE, Hausskn. — Slender-stemmed, firm, a span to a 
foot high, pubescent with very short subappressed hairs; leaves as 
much as 20 mm. long, linear, abruptly callous-pointed, mostly promi- 
nently undulate-toothed, sessile, cinereous on both faces, rather thick 
and firm and without conspicuous lateral veins; petals 6 mm. long, 
purple; capsules 60 mm., slender, on rather long slender peduncles; 
immature seeds obovoid, rounded at top, .6 x 1 mm.— Monogr. 253, pl. 
16, f. 73.— California, at the Russian Settlement (specimen in Hb. 
Petropol.), jide Haussknecht. 
Unknown to me, and suspected by Professor Haussknecht to be a 
hybrid of uncertain parentage. 
+ + + Producing at baseof stem in late summer and autumn, rosettes 
of foliage leaves, sessile or ending short scaly shoots: leaves not 
revolute, more or less toothed: seeds papillate. 
++ Habit of E. palustre: stems terete or with occasional low decurrent 
lines: seeds fusiform, prominently beaked.
