664 DRUMMOND’S NORTH AMERICAN MOSSES. 
nomenclature, I have no doubt that it will be acceptable to 
all who possess Drummond’s collection. I have translated 
in almost every case the German text literaliy, to avoid 
making the authors say in English what they may not have 
intended to say in German.

10. Phascum serratum var. stolon. valde remotis, is a 
young state of P. crispum, bearing the first fruit: the cap- 
sules are immature. It is extremely doubtful whether the 
accompanying Pseudocotyledones really belong to this 
species, 
11. Phascum crispum. The specimen marked B is the 
true plant : that marked A is Phasc. cuspidatum, and the same 
form as No. 7. 
12. Gymnostomum phascoides, is a Hymenostomum, differ- 
ing from H. microstomum var. capsula subglobosa, only in 
its shorter stems, and in the perichætial leaves, which ex- 
ceed in length the fruit-stalks. It may, therefore, be merely a 
variety cf the last species. 
13, 14, 15. Gymnostomum Heimii var. 1, 2, 3,—are forms 
which also occur in Europe, 
16. Gymnostomum latifolium, is Ptychomitrium acumi- 
natum, Bryol. Europ.—The leaves are only slightly broader, 
and more shortly acuminated. 
22. Gymnostomum pusillum, differs in no character of im- 
portance from G. Donianum, the plants being smaller, and 
the capsules rather shorter than usual. 
23. Gymnostomum tortile, is Gymn. rupestre var. tenellum. 
A perfectly similar form grows on the walls built of * Mo- 
lupe,” near Berne, and on the “ Nagelfluh,” near Munich. : 
30. Anictangium imberbe How; is Hedwigia ciliata var 
gracilis. um
