Lowermost frond branches further branched; veins fusing to form regular arches close to the branch rib but others free and forked. A variable species needing further study; very similar to P. pacifica. Pteris tricolor Painted Brake, is a name of no botanical standing. It is a fern that has new fronds that are bronze at first, the main stems and veins retaining a purplish colouration. This is probably a cultivar of P. biaurita and best recognised under the cultivar name 'Tricolor'.
