Notes. 
Table of the Results of cultivating Prothalli for a period of Two 
Years and a-half. 
[Note . — In every species normal embryos were produced when 
conditions permitted fertilization.] 
Names. 
Scolopendrium vulgare , Sm., var. 
ramulosissimum. 
var. marginale. 
Nephrodium dilatatum, Desv., 
var. cristatum gracile. 
Nephrodium Oreopteris , Desv. 
var. coronans. 
Aspidium aculeatum , Sw., var. 
multifidum. 
Results. 
Gametophytic budding. 
Development of archegonial projections. 
Development of cylindrical process usually 
from the apical region of the prothallus. 
,Tracheides in cylindrical process. 
Leaves, roots, and ramenta on 
process. 
Apogamy. J Sporangia on the process. 
Vegetative buds from tip of 
cylindrical process, or in place 
^ of an archegonial projection. 
Similar to var. ramulosissimum , but no spor- 
angia, isolated ramenta, or leaves found. 
Gametophytic budding. 
Development of archegonial projections. 
Development of cylindrical process, usually 
from the under-surface just behind the 
apex, which formed a ‘ middle lobe.’ 
I Tracheides in middle lobe and 
cylindrical process. 
Sporangia, sometimes associated 
with ramenta, on middle lobe 
and process. 
No vegetative buds. 
Gametophytic budding. 
Development of archegonial projections. 
Development of cylindrical process from apex 
of prothallus. 
S Tracheides in cylindrical process. 
Ramenta on cylindrical process. 
Vegetative buds (rare).
