D. déversa var. tarapotensis Ros. Fedde, Repert. 7: 298. 1909 from Peru, Ta- 

 rapoto, Spruce nr. 4066 pt (RR) is a peculiar form with distant pinnæ, the lowermost 

 pair much reduced; it belongs scarcely to the var. déversa (Kze.) as here under- 

 stood, but may be named Ü. patens var. tarapotensis (Ros.). It is densely glandu- 

 lose beneath, 



var. lanosa n. var. 



A large form of the macroura-type; characterized by its very dense pubescence 

 of the veins and indusia; the hairs are very long and the indusia are perfectly 

 concealed by a dense mass of long white hairs.

 L'Herminier (Herb. Cosson, Mus. Paris!) is probably a form of D. patens. The 

 specimen seen does not agree perfectly with Fee's figure but appears to be a young 

 plant with very thin leaves and crenate segments. Certainly the general habit of 

 the plant and the scales resemble more D. normalis than D. patens, but the rhi- 

 zome is erect. It must provisionally stand among the species dubice. 



191. Dryopteris Goedenii Rosenst., Fedde, Repert. 4: 296. 1907. 



Type from Rrazil, Sta. Catharina, Rlumenau, G. Goeden (R! also CC). 



A rather |)roblematic species, resembling very much small forms of D. Bangii, 

 but the rhizome is erect and the lamina not so decidedly narrowed downwards. 

 The scales of the rhizome is like those of D. mollis.

As type of this species I take the Jamaican form, well described by Jen- 

 man and first rightly understood by him. He says (loc. cit.): "this is distinguished 

 absolutely from all its . creeping under-ground root stock, upon which the fronds 

 are arranged in a bi-linear series". To this must be remarked that D. augescens 

 has a similar rhizome. 



U. nornialis is in general habit very near small forms of Ü. patens, and spe- 

 cimens without rhizome can not always be determined with certainty. Besides 

 the rhizome the scales show a constant specific character. The scales of the rhi- 

 zome and the basal part of the slipe are few, mainly confined to the growing apex
