Stan. posadae 'Kennedy' photo by Doug Pulley

This is a very attractive stanhopea! The large flowers are tawny gold with nicely overlapping sepals and petals. The lateral sepals are broad and unspotted; the petals and dorsal sepal have large chocolate brown or reddish spots. The lip is white; small chocolate-brown speckles on broad epichile (midlobe), with the appearance of oreo cookie crumbs.

The species is named in honor of Colombian orchid grower, Juan Felipe Posada, Medellín.

The original specimen upon which the recently published description was based, was collected by Rudolf Jenny on 22 July 1993. The holotype was filed in Geneva at the herbarium of the Conservatoire et Jardin botaniques de la Ville de Genčve.

Photomicrograph of Stanhopea posadae seed taken from a green pod, at right, by Lacey Powell, Meyers Conservatory, Jan. 2004. Her comments: "Seed is pale yellow to the naked eye, and lightweight and easily becomes airborne. Medium sized seeds are balloons, sometimes curved, and have moderately small sized egg-shaped dense embryos centrally located which are 1/5 the length of the seed. 96% of the seeds appear to have good embryos."
