terminadas en una puntita. Las fructificaciones solitarias en dos lineas immediatas al 
nervio principal de las pinulas secundarias. Los puntos son redondos como igualmente 
sus tegumentos. Don Luis Née la encontró junto à Chalma, pueblo de la Nueva-Espana. 
The best character of the species, the position of the sori, was clearly described 
by CavaANILLEs. FEE renamed the species of MARTENS and GALEoTTI, referring it to 
Athyrium, because the indusium is sometimes subhippocrepiform. A. agatolepis is 
the same according to specimens so named by FourniER (BouRGEAU nr. 1164). D. 
cinnamomea is exélusively a Mexican species and is very variable. "The typical 
form can shortly be described thus: Rhizome oblique, like stipe densely clothed 
with large (up to 2 em. long), ovate-acuminate, concolorous, red-yellow, thin and 
glossy, entire scales. Stipe stramineous, 10—15 cm. long. Lamina lanceolate or 
subdeltoid, firmly herbaceous or membranous, without hairs but more or less 
finely glandular on both sides by minute, glossy, whitish glands, especially on the 
coste beneath, fully tripinnate, about 20 cm. long by 10 cm. broad; the pale rachis 
and the green coste beneath with some few small scales. Pinnz opposite, the 
lower somewhat shortened, the longest 5—8 cm. long, 2—3 cm. broad, deltoid-oblong, 
mostly equal-sided or somewhat reduced on the lower side at base. Pinnules 
oblong or subdeltoid, the lower ones free, the upper decurrent; free pinnules 
equal-sided, fully pinnate at base; segments III entire or toothed, acute, ascending. 
Veins indistinct, forked in the segments. Sori nearly always solitary in the segment 
close to the secondary midrib, furnished with a large, flat, greyish, finely glandulose 
indusium, which is as a rule truly reniform but sometimes subhippocrepiform. 
In mature leaves the indusium appears often to be lateral (cystopteroid), because 
the sporangia come out at one side only, viz. that opposite the sinus. 
This typical form seems to be well-marked and not easily to confound with 
the much larger and less finely cut D. patula mexicana; the best characters are 
the position of the sori and shape of indusium, the equal-sided free, lower pinnules 
and the finely glandular surfaces. — The following specimens seen are typical:

A very doubtful species based on three imperfect leaves. It may be a form 
of D. cinnamomea. HikRoNvMus describes (Hedwigia 46: 346. 1907) a var. obtusa 
from Colombia, SrüBEL nr. 110, which I have not seen.
