Introduction

This small fern has highly divided leaves, with small involute ultimate segments, and is more reminiscent of species of Argyrochosma than it is of most species of Notholaena. However, it has the chromosome base number (x=30) of Notholaena, farina on its gametophytes, and is well embedded within core Notholaena II based on plastid DNA sequence data (Rothfels et al., 2008). It is a gypsum specialist, endemic to the Chihuahuan Desert of northern Mexico.

Characteristics

Notholaena bryopoda most closely resembles N. greggii. The two species can be distinguished by their rhizome scales (evenly colored and bright brown in N. bryopoda; black with brown margins in N. greggii) and their leaf-stalk scales (linear in N. bryopoda; lanceolate-ovate in N. greggii).

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.
