Taxonomic note
According to Leliert & Coppejans (2003: 61-2) "Hoek (1982: 169) proposed to synonymise C. rugulosa with C. prolifera,
based on descriptions and illustrations of C. rugulosa by Papenfuss (1943), Jaasund
(1976), Egerod (1975), Womersley & Bailey (1970), Sakai (1964) and Taylor (1945).
Other authors had differentiated the two species. Papenfuss (1943: 80) distinguished
C. rugulosa on the basis of longer cells, more prominent main axes, and more
pronounced annular constrictions in the cells. Papenfuss & Chihara (1975: 313)
argued that small rhizoid-like processes at the proximal end of the basal cells are
only present in C. rugulosa. van den Hoek (l.c.) rejects the above arguments because
rhizoid-like processes are also occasionally present in some C. prolifera plants and
cell dimensions are too variable in C. prolifera to split off the coarser C. rugulosa.
We compared the South African specimens with C. prolifera from Europe, Kenya
and Australia. Based on our observations two species, C. prolifera and C. rugulosa,
both occurring in South Africa, are not identical owing to completely different modes
of attachment. C. prolifera is characterized by the presence of rhizoids with annular
constrictions developing from the lower part of the basal cells, growing down along
the cells below where they entangle with one another to form a conspicuous %u2018stipe%u2019
(figs 5B, 6C, D). In C. rugulosa this kind of rhizoids is absent (Martens 1868: Pl. 2, fig. 3); here the plants are attached by basal branching rhizoids developing from the
base of a conspicuous stipe cell with annular constrictions. The rhizoids form a basal
clump giving off numerous, densely clustered stipe cells (fig. 5H). The South African
C. prolifera also differs from C. rugulosa by its smaller cell diameters, but since the
cell diameter of C. prolifera is shown to be very variable, this character is less useful
in distinguishing both species (Table 2)." - (16 February 2013) - M.D. Guiry
