Scapania irrigua, like most of the Scapaniaceae, has complicate-bilobed leaves with a distinct keel and a dorsal lobe that is smaller than the ventral lobe. There are no underleaves. The dorsal lobe has a pointed apex and both dorsal and ventral lobes are entire. The ventral lobes are broad. Oval, 2-celled gemmae can be present. Scapania irrigua is said to be common in the Western US and is found near standing water. Thanks to John Brinda for confirming the ID of this liverwort! Please click on an image for a larger file.
