Parentocirrus
- Parentocirrus hortualis Voss, 1997 (ref. ID; 7423)
Remarks
This species shows two ways of N1 anlagen development. The usual way for rows 4-6 is shown in the left computer graphic. The seldom occurring way similar to developments in Kerona polyporum is shown in the frame. Different from K. polyporum is the development of proter's row five, which is in P. hortualis generated by an anlage within the old row five and in K. polyporum by the N1 anlage in row four. In some rare specimens of P. hortualis the unused row six is not resorbed during cytokinesis, but is passed on to the next generation (old row between row six and seven). (ref. ID; 7423)
