Description.
The colony is
12 cm
long and
2.5 cm
wide, and sparsely branched (
Fig.
13
g). No calyces are present, polyp openings closely set to each other, and situated all around the branches.
The polyps have no sclerites.
Surface layer of coenenchyme with thornscales and unilateral spinose bodies, up to
0.50 mm
long (
Fig. 30
a).
Inner layer of coenenchyme has spindles, capstans, and capstan derivatives (
Fig 30
b–c); the capstans and derivatives are up to
0.10 mm
long, the spindles up to
0.35 mm
.
Colour.
The colony and sclerites are yellow.
Remarks.
Without thorough revision of the genus
Paraplexaura
we consider it impossible to identify species of this genus with any certainty.
