Introduction

This is the striking fern long known as Cheilanthes aurantiaca. Plastid DNA data, however, demonstrate that it is not closely related to Cheilanthes and is instead embedded within Notholaena (Rothfels et al., 2008), within which it has recently been given this name (Yatskievych and Arbeláez, 2008).

This species occurs in much of central Mexico, from Sinaloa to Oaxaca, where it prefers dry forests (usually oak or pine), and is typically found on or among rocks.

Characteristics

Notholaena ochracea has vibrant orange farina, a feature that is otherwise only seen in one or two species of African Cheilanthes (C. welwitschii; C. mossambicensis—in the hemionitids) and in the rare scaly Notholaena aurantiaca. The leaves of N. ochracea are elliptic or lanceolate, and tend to be pinnate-pinnatifid, with broad blunt leaf segments. This silhouette is distinctive, but surprisingly reminiscent of the otherwise very dissimilar Cheiloplecton rigidum var. lanceolatum.

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.
