Research on distichous vs rosette arrangement of leaves

Post by MatDz »

Hey all! After Sean's remarks during the recent convention about both distichous and rosette forms being observed among mature specimens of the same genera, sometimes separated geographically, and sometimes mixed up, I started wondering whether there are any studies on this topic? What makes individual specimens or populations go one way or the other? Also, why younger plants tend to be distichous, but later very often start spiralling?

PS: Sean didn't know the answer :mrgreen:

Late edit: I should have added, that the talk was addressing Gasterias, but the same phenomenon can be observed in e.g. Sansevierias (at least between juvenile and mature forms).

A tough one this is, I see (read it in Yoda's voice?).

I'll bump this one as I'd really love to understand this subject a bit better.
