For the description and discussion see Holý (1977b, p. 131). After the revision in 1977 some larger specimens from the Kristina Mine were identified by Holý (in scheda) as M. venosa (C. PRESL in STERNBERG) HOLÝ (1984). A definite solution of this problem would require a detailed study of the material from Podlesí and Počerny (the latter site being the type locality of M. venosa ).

Recently, a very similar type of fruits has been recognized in the modern species D. stachyanthus HANDEL-MAZZETTI from SE China and N Vietnam and D. vietnamensis AVERYANOV et T.H.
