Introduction

This Mexican endemic has linear to oblanceolate leaf blades (leaves broadest above the middle) and is known from disturbed habitats (roadside and stream banks) from the states of Jalisco and Oaxaca. Reports of this species from Central America are based on specimens of the similar N. montieliae (Yatskievych and Arbeláez, 2008).

Cheilanthes x coruscans is likely a diminutive specimen of this species, although it is morphologically distinct (Mickel and Smith, 2004) and might warrant recognition.

Characteristics

The light-colored leaf stalks and axes are unusual among notholaenids and serve to distinguish this species from other white-farinose species, except for N. montieliae. Notholaena rosei is also unusual among core Notholaena species in its relatively strongly differentiated leaf margins (false indusia) arching over and protecting the sporangia. In this character N. rosei approaches some members of Cheilanthes (as currently defined, including members of both the hemionitids and the myriopterids).

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
