Diagnosis
ReferenceDiagnosis
S. Stouge and G. Bagnoli 1999The apparatus is sexi- to multimembrate with distinct elements in P positions, nine 5 elements, one axial and four pairs, and a pair of elements in the M position. Morphologically, the P elements may be pastiniscaphate, pseudostelliscaphate, angulate or bipennate. 5 elements are alate, paired dolabrate to bipennate, paired tertiopedate and paired quadriramate. The element in the M position is paired, geniculate to tertiopedate.
