 fronds, tertiary anticous lowest veins reaching to the callose 

 sinuses of the segments or to a little al)ove the margin of 

 the sinus, carina rather broad or very narrow, involucres sub- 

 glabrous or long and densely setose." — Aspidiurn macrou-

 very <lifficnlt a group as § Lattrea of Nephrodium, that to which the present 

 Fern belongs, and of which A'. (Lastrea) patens may be considered the type, I 

 rely much pn the views of Dr. Mettenius, who has the best opportunity of know- 

 ing the species of the German botanists. I make use therefore of his specific 

 character here as upon some other occasions, and I shall only further remark, 

 that the individuals 1 consider belonging to this species scarcely differ from iV. 

 patens, except iu their generally larger and more luxuriant fronds, and more rigid 

 texture.
