The SEM study has allowed us to better study the nematophore number and structure of the cauline apophyses. These are relatively short and strongly directed upwards, which makes it really difficult to observe the axillary nematophores. This justifies, for example, that

, however, the presence of collar-shaped nematothecae is not constant. There are examples where it is absent, or not completely developed, in one or more of the axillary nematophores. On the other hand, the ‘mamelons’ of the cauline apophyses are sometimes little marked or even absent.

Concerning the number of nematophores of the cauline apophyses, there were three axillary nematophores emerging through simple holes in perisarc, but there was no collar-shaped nematotheca, perhaps related again to the bad condition of the material. In addition, there were up to two extra nematophores, each emerging through a ‘mamelon’, although they were sometimes absent.

(1997: 364) characterized the species by the presence of two “mamelons”, but pointed out that “towards distal part of the stem ‘mamelons’ of apophyses tend to become reduced or even absent”. However, they also indicated that circular perisarc holes were always present. In the present study, the variability in the number and development of the ‘mamelons’ has been confirmed. What would be characteristic for the species is the presence of two well-marked ‘mamelons’ (
