Milde says of it that the capsules are long-stalked with unmis- 
takable indications of a lid. These specimens were collected at 
* Blankenburg in the Harz Mountains by Hampe. 
Schimper, Hampe, Lindberg, Braithwaite, Husnot, Sullivant 
and Lesquereux and James (our American authorities probably 
cited the European) all state that P. patens may have the cap- 
sules either immersed or exserted, and Boulay states that it is very 
variable and that the different forms may be found growing 
“ pell-mell” in the same locality. 
Limpricht, in a foot note to his description of P. Hampei, says 
that Lindberg claims to have seen this form in the axils of the 
leaves of P. patens but that he has never seen it. 
_ We havea slight addition to make from our own observations, 
for in the Jeger Herbarium we find authentic specimens of 
Hampe’s labelled: “ Ephemerum patens var. anomalum. Seta 
exserta. p. Blankenburg. Ex. herbar. E. Hampe, 1865.” These 
specimens show what Limpricht says he has not seen, two kinds 
of capsules on the same plant. 
One plant which we have mounted has two capsules; the 
lower one small, immersed, with thin walls and characteristic large 
apical cells of Physcomitrella patens. The other is exserted on a 
thick seta 2 mm. long, with regular distinct cells in the walls of 
the capsules and a differentiated lid. The exserted capsules are 
almost all either young or aborted, so that no spores have been 
seen, but one old capsule has been found with the lid off, showing 
the mouth bordered with an orange-colored rim of cells and a dis- 
tinct annulus. The immersed capsules are on the lower part of 
the plants, as in our hybrid; most of the capsules are older and 
have perfected their spores with measure .024~.027 mm. and are 
rough.
