Abiotic Pollination - uses a nonliving vector - Usually considered to be a metabolically wasteful process Two types: 1. Anemophily- “wind lover”= wind pollination 2. Hydrophily- “water lover” = water pollination
Image of page 2
Anemophily -major type of abiotic pollination Usual Floral Morphology -incomplete flowers that often lack perianth -color and scent lacking -flowers in inflorescences elevated above the vegetation -flowers often open before leaves are produced -large quantities of smooth, dry pollen produced

Hydrophily -rarer type of abiotic pollination Usual Floral Morphology -color and scent lacking -perianth reduced -pollen often floats or have filaments in submerged species that act like grappling hooks
Image of page 10
Example of Families with Hydrophily Ceratophyllaceae (Coon-tail) Pg 529-530 SMIFNCT -mostly asexually reproduces by fragmentation -during sexual reproduction, anthers break off and float to surface releasing pollen that sinks to the female flowers that grow under the water -rare pollination in one of the most primitive groups magnoliophytes

Hydrocharitaceae (Waterweed) Pgs 1166- 1172 SMIFNCT Vallisnera (ribbonweed) or Egeria (Elodea is used as common name but is actually genus name of another plant that does not occur in Texas) -common aquarium plants introduced into streams and lakes of Cross Timbers. Vallisnera is native in some E and SE Texas waters -Female flowers float on surface and male flowers break off at surface (great fish food) and float to female. Once pollinated long peduncles recoil pulling flowers underwater to form fruits Example of Families with Hydrophily

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
