CARL CHRISTENSEN AND CARL SKOTTSBERG 



The remarks on fertility refer to my observations in 1908 1 and 1916— 17; 

 where I have reason to believe that a species occurs with ripe sporangia also 

 at other seasons, these remarks are put in brackets. 



We have adopted the nomenclature followed by CHRISTENSEN in his 

 > Index Filicum , where also explanations of the abbreviated book titles will 

 be found.

T. dichotomum Phil, was described from specimens collected by Germain (!). 

 No locality except >Juan Fernandez» was stated. In Herb. Kew is a specimen 

 collected by Reed(!) and labelled »Valdivia», probably in PHlLlPPl's handwriting 

 (HEMSLEY, 1. a). It is possible that this locality is false: Reed made ex- 

 tensive collections in both places and the localities may have been confounded. 

 Until further investigations can be made, the species should be listed as 

 endemic. 



T. Philippianum is one of the most distinct species of the genus. It has 

 been described and figured in details by VAN DEN BOSCH, but his description 

 and figure were not published until lately by GODDIJN. The numerous spe- 

 cimens at hand correspond fairly well with this description, but the species 

 grows much larger than his figure shows. The largest leaves are over 7 cm 

 long including the 2 cm long stipe. 



The filiform, wide-creeping rhizome and the basal part of the stipes are 

 sparsely furnished with reddish hairs, the plant otherwise being perfectly 

 glabrous. The leaves are either scattered or fasciculate in small tufts of 2 — 7 

 on short branches from the rhizome. The lamina is exceedingly thin, yellowish 

 green, the cells larger than in any other species of the genus, clearly seen
