When a rust's life-cycle involves two different host species it is described as?
Answers:
Heteroecious - life cycle alternating between two different hosts.
Puccinia graminis is heteroecious and is widespread on grasses in its uredinial and telial states, when it forms brown (uredinia) or black (telia) stripes on stems and leaf-sheaths. The grasses are the main, or primary, hosts.
The aecia and spermogonia occur on species of Berberis (barberry) and Mahonia (oregon-grape). Berberis and Mahonia are the alternative, or secondary, hosts.

I think it is called "heterodemicycyclic" but I wouldn't swear on it.
(Oh how sad the things we remember from University degrees that we never use again).
