| ABSTRACT In a Valdivian forest stand, we identified vascular plant species occurring as accidental epiphytes, and we determined the contribution of accidental epiphytism on their local abundance. Four species were found as accidental epiphytes, being the fern Blechnum mochaenum the species showing the higher abundance proportion as accidental epiphyte (40 %). Unexpectedly, individuals of this species occurring as accidental epiphytes did not differ in functional traits related to nutrient availability (LMA-leaf mass ratio- and leaf C/N ratio) from those that usually occur on the forest ground. As a shade tolerant and slow growing species, B. mochaenum apparently is not affected by the environmental restrictions of the epiphytic habitat. |

| ABSTRACT A new Chilean species, Asplenium patagonicum (Aspleniaceae, Pteridophyta), on the basis of the collections of vascular plants of South Chile is described. This Chilean fern has been reclassified from Asplenium monanthes L., given their differences in geographic distribution and morphological features. While A. patagonicum occurs in South Chile, A. monanthes presents a tropical distribution. The latter also is clearly distinguished from A. patagonium given its smaller size and different shape in their pinna; small, non-linear, and deltoid rhizome scales, and shorter general size. |
