In some cases, orchids and their pollinators have become so interdependent that their existence is mutually exclusive. [4] Pollination mechanisms resulting from this coevolution generally benefit both parties: pollinators obtain nectar from the flowers, while orchids gain pollen transfer.
Stanhopea orchids are mostly pollinated by large Eulaema bees, Euglossa species often being too small for the purpose. [12] In more primitive species in the genus Eulaema, the orchid pollinium, a packet of pollen, adheres to the male bee as it reverses out of the flower having collected the fragrance. In more advanced species, there is a fall ...
In some orchids ombrophily occurs, and rain water splashes cause the anther cap to be removed, allowing for the pollen to be exposed. After exposure, raindrops causes the pollen to be shot upward, when the stipe pulls them back, and then fall into the cavity of the stigma.
Kondrat recommends watering an orchid every 7 to 10 days when it’s potted in orchid mix. Orchids potted in moss need less frequent watering because the moss retains water longer.
All orchids fall into one of two general types based on their growth patterns, and you need to know an orchid’s growth pattern to prune it correctly. Monopodial orchids grow on a single stem ...
Orchids have developed highly specialized pollination systems, thus the chances of being pollinated are often scarce, so orchid flowers usually remain receptive for very long periods, rendering unpollinated flowers long-lasting in cultivation. Most orchids deliver pollen in a single mass.
Here’s what plants, flowers, trees and shrubs to avoid if you have allergies and preventative steps to take so that you can still enjoy gardening.
A pollinium (pl.: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. [1] [2] This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen ...
