An hypothesis is presented suggesting the evolutionary derivation of this type of head through formation of flo...

Puccinia spegazzinii (Pucciniales: Pucciniaceae) from Peru for biological control of Mikania micrantha (Asteraceae: Eupatorieae) in India: evaluating susceptibility of host populations and confirming host specificity
