Dryopteris sylvicola C. Chr. Ind. 297, 1905. 
The type-specimen of P. sylvicolum Bak. from Colombia, Prov. Antioquia, 
KALBREYER nr. 1807 (Kew!) is nearly exactly identical with the type from Ecuador. 
It is not so deeply cut, but the segments are similarly falcate and broadly crenate- 
repand, and the sporangia are intermixed with brown articulate paraphyses just 
as in the type.

The specimens on which Baker founded his two first named species are 
rather typical S. alloéoptera. P. heterophlebium from Costa Rica, leg. HARRISON 
(Kew!) has narrower pinnz and approaches S. longicaudata, from which it differs 
by its shorter and broader pinnz with many veins anastomosing. — P. oligophlebium 
from Peru, Tarapoto, Cerro de Guayrapurima, Spruce nr. 4653 (Kew!) is that form 
with few but very broad pinnz, which I have figured. In general habit and cutting it is 
nearly identical with S. opaca. The long stipe is clothed with several large, brown scales. 
P. coalescens Bak. was founded on a most wonderful mixture of different things 
collected by Soprro in Ecuador (Kew!) The type-specimen (a single sheet) con- 
sists of three young sterile plants and one fertile pinna. The latter is no doubt a 
pinna of S. alloéoptera, and two of the young plants are probably belonging to the 
same species. The third plant is entirely different and does not belong to Stigma- 
lopleris; what it may be, I dare not decide. I should not hesitate to make P. 
coalescens Bak. a synonym of S. alloéoptera, had Sopiro (Cr. vase. quit. 302) not de- 
scribed the species more fully, and his description does not agree perfectly with 
the specimen seen; thus he describes the stipe and rachis as pulverulento-pubescent, 
both surfaces pubescent and lamina impari-pinnate with the terminal pinna stalked, 
broader and shorter than the 5—7 pairs of lateral ones. These characters do not 
correspond to any species of Stigmatopteris. On the other hand his description 
very well agrees with the fertile pinna seen in other characters: size and shape 
of the pinne, venation and position of the sori.
