Odd question but....
Does anyone happen to have legal access to Lemna Obscura duckweed (NOT Lemna minor, which is what most aquarium duckweed is)? I have a lot of L. minor, which I give to the birds sometimes as a treat, but my understanding is that L. obscura has over twice the protein, so I'd like to look into getting some to propagate in my tanks instead. The only place I've found that has it is for research, grown on agars and expensive as heck, but I know it grows wild in the southern US.

Fat Duckweed (Lemna gibba)
Family: Arum Family (Araceae)
IUCN Conservation Status: Least Concern
A tiny aquatic plant found in slow-moving or stagnant freshwater habitats across much of Africa, Europe and the Americas, Fat Duckweed floats freely on the surface of the water, respiring and carrying out photosynthesis through a buoyant leaf-like “main body” called a thallus while its single submerged root hangs down and absorbs inorganic nutrients such as nitrogen (which plants need to produce chlorophyll) from the water around it. Although they do occasionally produce flowers (particularly when exposed to intense sunlight and low water levels,) members of this species primarily reproduce asexually, with the thallus developing bud-like offshoots that split of into new but genetically identical offspring, and through this method of reproduction (which can occur every few days) Fat Duckweeds can quickly spread over vast areas, potentially near-totally covering the surface of the body of water they inhabit under ideal conditions. The root of an adult Fat Duckweed is sticky, allowing members of this species to compensate for their limited ability to spread their rarely-produced seeds by adhering to semiaquatic animals such as ducks, allowing them to be carried between bodies of water and colonise new areas (hence the name, “duckweed.”) If an individual should fall from the animal that was carrying it before reaching a suitable body of water, it may also be able to survive in sufficiently damp soil.

A well known river hag from English folklore. Tales of her presence were used as a deterrent to prevent drownings in dangerous waters such as those choked by duckweed or algae.

had my first day of plant systematics today and man. I'm so excited for this class. Day one and I received two pieces of information that blew my socks off in two different ways:
1. We will be going to see Isoetes in the field! and
2. Duckweed (Lemna) is in the freakin' ARACEAE family?!?!? Yknow. Corpse flower and skunk cabbage? Calla lily? Thermogenesis? Stinky? LARGE and in charge? And this is why morphological classification is on such thin fuckin ice. Man. I'm reeling. I love learning new things about plants because they will ALWAYS surprise me.

Duckweed is growing into such a handsome snake. These guys are becoming some of my favorite animals I work with. They're incredibly docile, inquisitive, and active (at night!). Easy feeders with very simple husbandry needs too.
