Summary
| Description | This closer view of Pentagramma pallida shows the frond architecture as delimited by the whiteness of the rachis and the costae (pinna midribs) conferred by an exudate ("farina") produced by the plant. Note that the pinnules on the lowermost pinnae are much larger and more divided on the side pointing to the frond base (towards the top in the image) than the corresponding pinnules that point towards the apex. This is a common feature in some genera in this family (Pteridaceae) and other families such as Dryopteridaceae. Photographed in Sequoia National Park, California, on a trail near Hospital Rock at about 2,700 feet elevation. Image imgl0188, March 28th 2017, | |||||||||||||||||
