The specimens from Juan Fernandez (== H. semiteres Colla, 
Mem. Ac. Torino 39: 32 tab. 61) differ from the Chilean ones 
seen by me by being less divided, generally tripinnatifid, ra- 
rely quadripinnatifid with broad lobes and a wing 2 mm. 
broad to the rachis. This form has fully the same aspect 
as H. caudiculatum, but the sori are widely different. 
Juan Fernandez: Masatierra, forest by »El Yunque», 
24.28. 1908. 
A much divided (quinquepinnatifid) and narrew-lobed 
form with a very narrow wing to the rachis (scarcely 1/2 
mm. broad) was collected by P. DusÉN in West-Patagonia, 
Aysén valley, 3. 1. 1897. 
Sterile specimens of ZH. caudiculatum and H. fuciforme 
are often confounded in the herbaria; the two species can, 
however, easily be recognized by their different rhizome, which 
in H. caudiculatum is very slender, wide-creeping and produces 
leaves at large intervals, in H. fuciforme short, thick, almost 
bulbose with subfasciculate leaves and densely clothed with 
peculiarly looking hairs at the base of the stipes. They are 
of a deep red colour, cylindrical with an acute point and 
distinctly articulate by 6—10 transversal walls. Similar hairs 
are found by the base of the stipe of H. caudiculatum, but 
in this species they are much fewer and shorter. 
Hymenophyllum tunbridgense (L.) Sm. 
Juan Fernandez: Masafuera, by a stream, 1,200 m. 
2i s OOS. 
The first sure record of this species for the islands. It 
was enumerated by JoHow on the authority of PHILIPPI and 
Gay although it was not found in the collections from the 
islands known to him. The specimens were found growing 
with H. cuneatum and are very typical.
