Polypodium calirhiza--Polypody Fern
This fern looks so lush and lovely now at the UC Botanical Garden. It is at its best in the rainy season, and dies back in the summer. I love the bright yellow spores under the leaves (I guess they are actually sporangium, but who says that?). It grows in Oregan, California, and Mexico, sometimes in the ground and sometimes in trees. The name comes from P. californicum and P glycyrrhiza because it is a hybrid of the two and recognized as a separate species in 1991. It likes growing in the shade, under oaks and other trees.
The Polypody ferns look so lush and lovely now, after all the rain.
