Sertularia L. (exclusive of several species). Polyps funnel- 
shaped; tentacles hispid, numerous, arranged in a whorl at the 
base of the mouth. Polypary corneous, simple or ramose, with 
cup-shaped cells sessile, or subpedunculate, with short pedicle, 
distinct from the stalk. Polypiferous cells sterile; others fertile, 
oviferous, scattered over the stalk and branches, situated usually 
near the base. 
The Polyps of this genus do not differ from those of the former, 
but the cells are non-pediculate, or the very short pedicle is dis-
