Calliarthron Manza, 1937 |
Calliarthron is a genus containing two species of thalloid intertidal [1] alga. Specimens can reach around 30 cm in size. The thalli take a crustose form. The organisms lack secondary pit connections. Calliarthron reproduces by means of conceptacles; it produces tetraspores, dispores and carpospores. The genus has lignin and contains secondary cell walls, traits which are normally associated with the vascular plants. [1] It is similar to the genus Bossiella. [2]
Calliarthron is calcified, but also has uncalcified joints that allow it to flex in response to the waves to which it is subjected. [1] These joints start out calcified, and decalcify as they grow older. [1] After decalcifying they grow much longer, then fatten themselves up in the same way as xylem formation, resulting in secondary walls. [1]
The 2 species currently recognised are: [3]
