and the coste above strigose by longer setz, still less so in D. honesta and D. yungensis 
(which perhaps are identical). 
The only more divided species that I place here is D. flexuosa, described below ; 
it seems related to D. defleca and I cannot find any other natural position for it. 
, I have nothing to add to my former treatment of the bipinnatifid species 
belonging here.

Type from Brazil, near Rio Janeiro, leg. Guaziou nr. 2458 (H!); also nr. 
4668 (B, H = Ph.. camptocavion Fée). 
A most remarkable species of § Ctenitis, in several important characters totally 
different from all other decompound species but perhaps related to the bipinnatifid 
D. deflexa (KIf.) C. Chr. It was described separately both by F&r and Baker under 
the same specific name and well illustrated by Fe&re. FEE described it again as 
Ph. camptocavlon, which may be explained by the circumstance that he had an 
upper, less divided pinna only; lower and larger pinnz (of the same frond) in B and 
H are typical. Fér’s illustrations give a fair idea of the species, and I add to his 
descriptions some supplementary notes: I have like other authors seen pinne only. 
Primary and secondary rachises often zigzag. Pinne up to 35 cm long, acumi- 
nate. Pinnulz distant, nearly all stalked, the upper.ones not decurrent, the lower 
often reflexed, up to 10 em long, 2—3 cm broad, pinnatifid '/e—*/s of the way down 
with somewhat arcuate, obtuse lobes ‘/2 em broad; basal posterior lobe often 
somewhat reduced and nearly free, the anterior one very small or often quite absent 
(conf. Fée’s tab. 98). Rachises and midribs beneath rather scaly; scales ovate or 
lanceolate, fimbriate, very thin bright-yellow (not unlike those of D. deflexa), inter- 
mixed with long and very thin woolly hairs; margins, midribs and veins above with 
dark-brown Ctenitis-hairs’; surfaces otherwise glabrous, the under one finely and 
sparsely glandular. Veins simple or sometimes fureate, 6—8-jugate, arcuately ascen- 
ding, reaching the margin, the anterior basal one ending in the leaf-tissue below 
the sinus. Sori a little inframedial. Indusia not found.
