412 ~ POLPYI. 
DisricopHora, Lam. 
Where the more strongly marked pores are arranged on two 
sides of the branches(1). Of those in which the pores are equally 
distributed, we distinguish 
Mitierora, Lam. 
Or Milleporz proper, which are solid, and variously ramous(2). 
When their pores are not apparent, as is sometimes the case, they 
are called Nu Lirrora(3). 
Then we have the 
Esouara, Lam. 
Which are furnished with flattened, foliaceous expansions(4). 
Rerepora, Lam. 
Which are Eschare, pierced with meshes(5). 
Aperona, Lamour. 
Escharz borne on an articulated stem; some are entire, and others 
pierced with meshes(6).
