into one another through many gradations. Also an agreeable blood-red 
shade occurs. 
The fruit appears on the ends of the stems, where it often remains unde- 
veloped. It comes, however, in respect to its structure and development, 
nearest to Jungerma 7 inia veniricosa. One chief difference lies, to be sure, 
in the structure of the perianth, which in J. alpestris is longish, almost 
cylindrical, without keels, obtuse, while in J. ventricosa it is short, swollen, 
plicate above, and with sharply toothed mouth. 
Remarks on the differences of the two species. 
Remark 2. The hollow form of the leaves on the fruit-bearing stem, 
while on the fertile Jungermannia veniricosa they stand out flat. 
Remark 4. Jnnger 7 na 7 inia ve 7 itricosa is almost always grass-green. 
Remark 6, The brown, not yellow gemmae of the plant, which other- 
wise resembles Ju 7 iger 77 ia 7 i 7 iia veniricosa.'' 
Stephani ^ refers to it as follows; “ Leaves extraordinarily different in 
form, as broad at the apex as at the base, yet also often narrower, tips acute 
and unequal, somewhat bent inward; the leaves on one and the same stem 
hardly resemble each other in form, and from this the plant is easily recog- 
nizable, One of the species that is oftenest confused.’’ 
However, its identification should offer but little difficulty after reference 
to the above-mentioned peculiarities, and it may even penetrate as far south 
as Mt. Greylock, Mass.
