About plant names...
The rattlesnake plant's flowerlike yellow spike looks a great deal like a rattler's tail. The plants
are native to regions between Nicaragua and Ecuador. It is naturalized in Hawai‘i now.
I see this plant variously called Calathea crotalifera S. Watson, Calathea insignis,
and Calathea lancifolia. But these plants differ significantly, and only C. crotalifera
has the distinctive yellow rattler flowerheads.
Identification: The yellow spike that is this plant's
namesake is a set of bracts (modified leaves)—the true flowers are small and purple, poking out
of the sides of the leaves.
