Peña Cantero & García Carrascosa (1995) did not find any mesial inferior nematothecae when they examined this material, a pattern corroborated herein by SEM analysis.

Until now only two axillary nematophores in the cauline apophyses had been described for this species. However, we observed three with the central one being larger and sometimes with the appearance of being the result of coalescence of two central ones (
