Culberson, CF/ Culberson, WL/ Johnson, A 1990: A novel meta-depside from the Ramalina subfraxinea complex (Ascomycotina, Ramalinaceae). - The Bryologist93(2): 193-196. [RLL List # 140 / Rec.# 3736] Keywords: RAMALINA/ CHEMISTRY/ NEW CALEDONIA/ 4-O-METHYLOXOCRYPTOCHLOROPHAEIC
Abstract: 3 figures. 2 tables. ["The chemical structure of the new meta-depside supports a recently proposed scheme for the biogenetic relationships of orcinol-type lichen products in which meta-depsides are derived by 3'-hydroxylation and rearrangement of para-depsides." Collections of the Ramalina species were from New Caledonia.]
