Wrangelia nob ills Hooker et Harvey. 
Fronds 15 cm. to 30 cm. long, corticated from base upwards, 
branches patent, irregularly pinnate. Young fronds are clothed 
with very delicate rosy-red ramelli, 4 mm. in length, giving a 
feathery character to the branches ; this tomentum is close pressed 
and silky. In older fronds the rosy ramelli become much less 
abundant, and eventually are confined to the tips of the smaller 
ramuli, while the tomentum becomes more shaggy and uneven. 
Finally the rosy ramuli fall off entirely, and at this stage the 
fruits are produced. Cystocarps typical for the genus, borne on 
longish pedicels issuing from the older branches. Tetraspores 
densely aggregated in grape-like clusters, surrounded by involucral 
ramuli, borne on little pedicels rising from the branches.

Wrangelia balloides J. Agardh. 
Fronds to 40 cm. high, corticate with dense filaments from the 
base ; pinnately branched, with verticillate ramelli at the nodes ; 
vegetative branches plumose, with the verticils distinct, approxi- 
mating ; verticils of branches heteromorphic, the one long, 
subdistiehous, diverging, alternately pinnate and much branched, 
the other short, leaf -like on both sides; above incurved, subcon- 
verging, cylindrical ; all apices obtuse, slightly attenuated ; 
articulations of ramelli about three times as long as broad. Tetra- 
spores on upper incurved ramelli, triangularly divided.
