Identifying Narcissus species

Rodger makes some excellent points. There seem to be similar phenomena in
epiphytic rhododendrons and bromeliads, where disturbance such as road
building or logging creates light gaps that alter the behavior of
pollinators and modify opportunities for the plants. Some vireyas are
relatively uncommon in closed-canopy forest but roadsides in the same
forest can create ideal secondary habitat for them to thrive and meet with
congeners they would otherwise be more isolated from. The case is probably
more dynamic with bromeliads like Guzmania species since their seeds are

Regarding Narcissus, it's too bad there is not a formal taxonomic rank of
"species complex" for a suite of closely allied taxa that may intergrade
with one another-- or may be actively diverging from one common ancestor.
