Description
Summary:Fig. 5. Candelabrum phrygium, histological sections of blastostyles, oriented vertically, males and females originate from different, unisexual individuals, all Kam09. (A) Mature female sporosac with a young polyp (yp); ep = epidermis of sporosac. Note, the layers of the juvenile are inverted, the tentacles (te) directed towards the inside. This inversion is also known to take place in other Candelabrum species. (B) Youngest female sporosac observed, oc = oocyte. A part of the distal epidermis is lost. (C) Epidermis of a male sporosac with a nematocyst button (nb). (D) Two advanced male sporosacs, note the absence of a pedicel or stalk, the sporosacs arise within the epidermal layer, bs = blastostyle. (E) Mature male sporosac. ...
