Diagnosis |
Escal bulb without membranous anterior crest. Distal escal appendage compressed, transversely fan-shaped, bearing three bony escal hooks along posterior margin, without elongate prolongation emerging from bases of escal hooks. Posterior escal appendage cylindrical, tapering to a point (Ref 27827). Length of illicium 43-44%SL in small specimens, 47-50%SL in large specimens (8 to 11.2 cm); posterior escal appendage 0.5-2.5%SL, emerging from below escal pore; thin edge of distal appendage behind and between bases of escal hooks more or less folded; length of distal appendage, measured from surface of escal bulb to bases of escal hooks, 1.3-2.8% SL (Ref. 86949). |
