Today’s photos focus on the inner portions of the beautiful Phalaenopsis orchid flower which we received as a gift. The innermost parts of the Phalaenopsis orchid flower have various names – such as column, lip, and throat. The meanings for the labels on the photo of the orchid flower above, are as follows:
Column . . . . the finger-like structure or column-like extension between the two largest petals. It is the central reproductive organ of the orchid flower.
Anther Cap . the cap-like structure which terminates the column and covers the pollinia (mass of pollen grains).
Throat .. . . . . . the inner portion of a tubular orchid lip, often quite colorful.
Callus . . . . . . . the raised, fleshy or plate-like structure found on the labellum.
Labellum . . . or Lip, is the lower petal that is used by the orchid to provide a ‘landing platform’ for its pollinator.
The next couple of photos below show the anther cap with pollinia resembling two eyes of an insect. I read here that the Phalaenopsis orchid is also called the Moth orchid since it boasts long arching sprays of flowers that sort of resembles a flight of pale moths in moonlight. The Phalaenopsis orchid normally flower once each year, initiating the new bloom spike in autumn. It may have 15 or more orchid flowers per spike, and its flowers remain open for six weeks or longer.
Here are a few more photos of looking down the throat of this beautiful and popular orchid. The final photo is another labelled diagram of the Phalaenopsis orchid or Moth orchid.
