Subject: Re: [aroid-l] Xanthosoma "roseum"
Dear Tom,
Yes, X. robustum is the only big Xanthosoma widespread in Mexico. I have
seen it from Mexico City to Chiapas and probably it ranges down to Costa
Rica. Xanthosoma roseum is not the older name. Xanthosoma robustum were
described in 1853, whereas X. roseum was described in 1858. I am treating
them as synonims, since the stated differences between them are within the
variation range of X. robustum. Many species were determined as X. roseum,
only because they have a pinkish spathe or a pinkish sterile portion of
spadix. The feature is known for X. robustum, X. blandum, X. mafaffa and X.
sagittifolia, so it is not a good diagnostic feature.
Very best wishes,
Eduardo.
