KEY TO SPECIES OF WRANGELIA
1. Ends of thallus branches more or less terete; whorl-branchlets subdichotomously to unilaterally branched; cortical rhizoidal cells not producing an outer layer of branchlets | 2 |
1. Ends of thallus branches strongly flattened owing to greater development of lateral whorl-branchlets; whorl-branchlets alternately pinnate or subdichotomous; corticating rhizoid cells producing an outer layer of branchlets | 4 |
2. Terminal cells of whorl-branchlets mucronate, L/D | W. velutina |
2. Terminal cells of whorl-branchlets not mucronate, usually L/D more than 2 | 3 |
3. Thallus | W abietina |
3. Thallus (2–) | W. plumosa |
4. First- and second-formed whorl-branchlets of each whorl formed on opposite sides of the axis, strongly developed and reaching 3 mm long, other whorl-branchlets shorter, terminal cells acute; outer cortical branchlets terminating in acute cells | W nobilis |
4. Whorl-branchlets formed in alternating sequence with the first- and second-formed of each whorl on the same side of the axis, alternating on successive axial cells, villose and reaching 4 mm long, other whorl-branchlets much shorter with terminal cells mucronate; outer cortical branchlets terminating in large spherical cells | W australis |
