Conference Paper
Full-text available
The diversification of angiosperms poses an intriguing evolutionary puzzle that has been attributed to the origin of the flower. Pollinator-mediated selection stands as a key force driving the astonishing diversity of floral forms observed in angiosperms, but its role in the diversification of Urticalean rosids has been neglected. Utilizing the Mor...

Question
Hola! I'm having some issues interpreting 22.1 and 22.2 articles. From what I've read if the type species of a subdivision of a genus is NOT "listed" in the autonym subdivision, then that makes that group not validly published.
For example, if I have among the binomials LISTED under Protea subgen. latina sect. dubia, Protea ficticia (type species of Protea subgen. latina), that would make Protea subgen. latina sect. dubia invalid. The correct name should be Protea subgen. latina sect. latina.
When dealing with these articles is it enough that the binomial was "listed" to these to apply?
Question
The Shenzen Code in his several articles treats the way botanists should move around nomenclature. It is interesting to read all the several examples that the Code brings for each case. However, there is nothing (as far as I´ve read) that states what to do when the description does not fit the features of the holotype designated. In other words, a name could be rejected when the description or diagnosis does not resemble what is seen on the holotype designated?. I mean (again), what happens when someone decides to propose a name based on a description and diagnosis with invented features that are obviously not found on the holotype designated?! any thoughts?
Question
Hello colleagues! im actually revising some Peruvian Stelis (Orchidaceae) and I encounter with a confusing issue. Maybe someone here could help me. On his latest work, Luer described S. miranda a newly species from Colombia. His notes mention its resemble with three Bolivian species: S. antennata, S. saltatrix and S. ballatrix. Here comes the problem! I was unable to find any reference to the last two species mentioned. Apparently S. saltatrix or S. ballatrix non-exist either on Tropicos or IPNI. Does anyone know where this two species were published?
Thanks!!!
