Orthotrichum diaphanum Bridel

Family: Orthotrichaceae

Status: Native

Synonyms:
Orthotrichum garretti Grout & Flowers

Orthotrichum diaphanum was found growing on an Alligator Juniper at 6,700 feet elevation. The capsules have 8 pairs of widely spreading teeth. The leaves are mostly ovate-lanceolate to a broadly acute apex but sometimes quite slenderly acute. The distal leaves have a hyaline awn that is easily broken off and may not be present on younger leaves. The papillae are low, indistinct and sometimes missing on the leaf cells. Many thanks to Ricardo Garilleti for identifying this specimen for us.
