??????????From Hacienda La Ciénega, near Cotopaxi, Ecuador.

This calla lily (Zantedeschia spp.) from the gardens of La Ciénega sports a yellow spadix, which is an inflorescence of small flowers on a fleshy stem.  The white part of the calla, called the spathe, is actually a bract or modified leaf, which acts like a petal to guide pollinators to the spadix.
