I will be using some botanical terminology from time to time to discuss the physical characteristics of these orchids, so I thought it would be appropriate to provide a post that outlines some of this terminolog.
|Stanhopea anfracta flower|
The column in orchids is the organ where the reproductive parts are placed, is the union of both male and female structures, and is the innermost structure. In Stanhopeas, the column is an elongated cylindrical organ that creates a tight space between the horns and epichile that allows the pollinating insect to be positioned so that the pollen cap is removed, and the pollen sac deposited on the back of the insect. This action also opens access to the stigma to allow pollination to occur by the next insect carrying a pollen sac.
Stanhopea graveolens pseudobulb
Stanhopeas have pseudobulbs that sit at the surface of growing medium and are often rounded or egg shaped. These storage organs are used to store water and nutrients for the plant. The larger the pseudobulb, the more mature the plant is, and the more likely that the pseudobulb will produce an inflorescence (flower stalk). At the top of the pseudobulb is the cylindrical base of the leaf called a petiole, and at the top of that is the blade of the leaf. Below the pseudobulb, roots are produced to allow the plant up take up nutrients and water.
