but smaller and more ovate-lanceolate and divergent scales. Margins ciliated with 
articulated hairs; surfaces glabrous the midribs excepted that are rusty-pubescent 
like other species of § Ctlenitis. Veins in ultimate lobes pinnate, c. 3-jugate, simple, 
somewhat pellucid, that of the posterior basal adnate lobe springs out from the 
costula above its base and is often pinnate on the upper side only. Sori medial 
on the vein, generally distributed over the whole lamina, small. Indusia subpersistent, 
reddish, glanduloso-pubescent and ciliate. 
_ METTENIUs united into a single species, A. catocarpum, two species described 
by Kunze, A. nemophilum and A. catocarpum, both Peruvian, and since the name 
nemophilum has been entirely forgotten. Unfortunately Merrenius used the name 
eatocarpum, although it is evident that A. nemophilum is the fully developed state 
of the species, and morover, it is the species first described. It is probable that 
METTENIUS has seen the original specimens of KuNnze’s two species, and I have 
. come to the conclusion that he was right 
in uniting them; his description is drawn 
up after specimens from Venezuela and 
Colombia, which I have examined and 
which agree rather well with the origi- 
nal description of A. catocarpum. When 
I prefer the specific name nemophila, it 
is not caused by the reasons mentioned 
above only, but also because I have a 
specimen from Peru (Ruiz nr. 69), which 
is determined A. nemophilum by KuNzE

of f. fuscata (Linden n. 1020); c. ditto of f. catocarpa §™en correspond perfectly some others 
from N. Argentina, all nat. size. from Ecuador, collected by Sopiro and 
i . MILLE (Nephr. amplum Sod. part.). They 
represent the form described above. This form is easily distinguished from D. ampla 
by its much larger size, its very obtuse terliary segments with close, falcate lobes, 
and by the subpersistent, reddish indusia. The colour of the scales are different 
but in shape and structure similar to those of D. ampla, the brown colour of the 
dried leaf that is less glandular is very characteristic. 
The main-difference between the described typical form and the form described 
as Aspidium furcatum Klotzsch is the smaller size and less divided leaves of the 
latter ; the tertiary segments being scarcely more than faintly dendate. Aspidium 
catocarpum Kze. is still smaller and less divided; its longest pinnz are 20—30 cm 
long a shorter, most secondary pinnulze sessile, decurrent at base, obtuse and in- 
cised till more than halfway to the costule into oblique, oblong, obtuse entire, often 
falcate lobes. A secondary pinnula of this form resembles in size and cutting a
