Key characteristics

The following key to the varieties of P. coerulea has been adapted from Zizka et al. (2013)

+ Flower bracts shorter than the flower stalks = var. violacea

+ Flower bracts about as long as or longer than the flowers stalks

+ + Flower bracts exceeding the middle of the sepals = var. coerulea

+ + Flower bracts shorter than the middle of the sepals.

+ + + Inflorescence densely & persistently white-tomentose = var. intermedia

+ + + Inflorescence hairless during flowering = var. monteroana
