Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Introduction

Danaea simplicifolia is one of the few species in Danaea that has simple leaves in adulthood. This retention of a juvenile character (neoteny) can also explain why sometimes the plants get a few extra pinna protruding from its single node. It has been suggested (Christenhusz, 2007; Christenhusz et al., 2008), that the once pinnate leaves of Danaea and Angiopteris (clades "Archangiopteris" and "Macroglossum") can also be explained by neoteny.

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.
