Stanhopea quadricornis from Illustrations of Orchidaceous Plants
Stanhopeinae is a subtribe of plants in the Orchid family.
The subtribe in the strict sense, have viscidia and stipes that are thin and strap-like, they are adapted for attachment to edge of the bee's scutellum or to a leg. Pseudobulbs are usually ribbed/four-angled or flattened. Leaves are generally thicker than Coeliopsidinae. Roots are smooth, without prominent root hairs. The column foot is lacking or not distinct. Unpollinated flowers quickly abscise and fall from the inflorescence, unlike members of Coeliopsidinae which include Coeliopsis, Lycomormium & Peristeria. Stanhopeinae and Coeliopsidinae are now considered closely related sister subtribes.
The genus Archivea is only known by a watercolor painting by T. Duncanson in the herbarium archives of the Royal Botanic Gardens, Kew. No pressed specmins or living material is known, so it can not be grouped into a specific clade.
All species in this subtribe are exclusively pollinated by male euglossine bees, which are attracted to the floral fragrances, and collect them. One orchid species may attract only one or a few species of bees from dozens of species in the habitat.
