The paphiopedilum is difficult because the pollinia are in an awkward place behind the staminode and the stigmatic surface; the plate at an angle to the column with three lines radiating from it at an angle of 120 degrees is even more inaccessible.
The procedure by which man pollinates an orchid is mechanically identical to that by which an insect pollinates it, except that man has advantages.
The process of germination varies considerably with different genera and species.
In the case of Dendrobium, such as Dendrobium nobile, the task, for an insect, is much simpler and less hazardous.
The fertilization of paphiopedilums is slightly different from the other various methods by which the continuance of the rase is ensured.
