Zygodon viridissimus forma australis 
Correns. 
In this form the brood-bodies are 
numerous and almost all sprouted, as 
in all the species of Zygodon which have 
been investigated, being borne on much 
branched rhizoids which are clustered in 
the axils of the leaves. The brood- 
bodies are shorter and less divided than 
in figure 70, the form which Correns 
calls Zygodon viridissimus f. australis 
occid. from the Voges and Departments 
of Lot and Garonne, France. The 
Northern form which ours most resem- 
ble, Fig. 71, which Correns calls Zygo- 
don viridissimus (genuinus) f. borealis 
Correns came from Neuruppin, Ger- 
many, and has 4-6 septate brood-bodies 
which are much simpler than the South- 
ern forms. Thus far this is the only 
form we have found in America, as our 
specimens all came from elevations vary- 
ing from 2200 to 5000 feet and are 
distinctly boreal in distribution.
