Have knowledge of USDA Noxious weeds and regulations?
My husband grows aquatic plants for aquarium hobbyists. He has recently learned that two of the plants he grows, limnophila sessiflora, and hygrophila polysperma, are designated as “noxious plants” and their transport is regulated here in the US. What we need to know are three things…
1. Would all subspecies of these plants be included as noxious weeds even if the specific subspecies is not specified by the USDA noxious weed list? Specifically, he grows the “tropic sunset” variety of hygrophila.
2. What are the penalties for selling and transporting these plants within the US?
3. Is it difficult to obtain permits for plant transport for private sale for aquarium use?
We have already tried searching the USDA website and cannot find answers to these questions.
To Amy L. – thanks for the additional information despite the condescending attitude and off-base assumptions you have made. My husband bought his plants from a reputable dealer – they did not tell us that these plants were restricted, and we incorrectly assumed that if he was selling them, they were legal. My husband only sold two batches of plants before finding out they were on the noxious weed list, he has since stopped selling until we are more educated on the policies, and receive a permit for transport. I asked of legal consequences in case those two previously sold batches came back to haunt us, NOT to skirt the law for future sales.
He pays taxes on his income. And he knows the environmental consequences of noxious weeds and has NEVER disposed of any plant in an irresponsible manner. We are asking these questions not to evade the law or work around the system, we are asking so that we can be responsible plant growers and sellers.
But thanks for assuming the worst!

Elaborate Carnivorous Plants Prove To Be Kin
1. The Venus flytrap has a muddled family history. Charles Darwin thought this elegant bug eater from
the southern United States had close ties to a European aquatic weed called the waterwheel. A
century later, researchers decided that the waterwheel’s closest kin was not the Venus flytrap but the
terrestrial sundew, which also dines on insects. Now a DNA analysis of these botanical carnivores
suggests that Darwin’s hunch was right after all.
2. In many ways, this revised family history makes sense, comments Mark Chase, a plant systematist at
the Kew Royal Botanical Gardens in Surrey, U.K., even though he once suggested otherwise. Of all
the plants that feast on animals, waterwheels and Venus flytraps “have taken carnivory to the
extreme,” he notes. Each has leaves reshaped into traps that snap shut. Now that their close
relationship is “nailed down, it sets the stage for people to ask more intelligent questions about how
these mechanisms evolved,” Chase points out.
3. Carnivorous plants have come up with a variety of ways to snare their prey: pools of water for
drowning unlucky visitors, sticky surfaces that work like flypaper, or “snap traps” that clam down on
morsels in milliseconds. Sundews are flypaper predators; waterwheels and Venus flytraps depend on
snap traps. All use their prey not as a food source but to provide minerals.
4. Evolutionary biologists have long speculated about how these features evolved. In the late 1800s,
Darwin picked up on similarities in the stamens and pistils – a flower’s reproductive parts – of
waterwheels and the Venus flytrap and suggested that these two plants were closest kin. However, in
the early 1990s, Chase and his colleagues threw a fly in the ointment, so to speak, when they
compared the DNA of about a dozen carnivorous plants and took a closer look at their morphology.
They had no DNA from waterwheels and so relied solely on morphology (Science, 11 September
1992, p. 1491).
5. The 20th century study led researchers to conclude that they should lump the sundew in with the
waterwheel and push the Venus flytrap out of the tight-knit group. This family tree had evolutionary
implications, says Richard Jobson, a plant systematist at Cornell University in New York. Snap traps
might have evolved twice, once in the waterwheel and once in the Venus flytrap.
6. Now a 21st century DNA analysis tells a different evolutionary story. Jobson, Kenneth Wurdack of
the Smithsonian Institution in Maryland, and Kenneth Cameron of the New York Botanical Garden
have compared four genes instead of the one studied in the 1990s. They conclude that even though
the Venus flytrap is terrestrial and the waterwheel aquatic, the world’s only two snap-trapping plants
are nonetheless siblings. The sundew is no closer than a cousin, sharing a common ancestor much
earlier in time, the group reports in the September issue of the American Journal of Botany.
7. Cameron and his colleagues contend that this evolutionary arrangement suggests that snap traps
evolved only once. Moreover, “our results demonstrate that snap traps evolved from flypapertrapping
plants,” he says. They also think that among snap trappers, the Venus flytrap came first.
8. Chase thinks the snap-trap story might be more complicated than it now looks. The two species “don’t
live in the same parts of the world,” he explains, and although fossils show that the waterwheel was
once common throughout Eurasia, the Venus flytrap is known to grow only in North and South
Carolina. That leaves open the question of where the snap-trap plants got started and how they
spread.

Conver MC105-10 Aquatic Weed Harvester
Conver MC105-10 aquatic weed Harvester I have come across several of these machines in Europe. Very special equipment to remove submerged and floating vegetation from watercourses and lakes. A special twin anti coiling auger makes sure the machine does not get stuck in weeds and a switching system makes it possible to both load and discharge on the front of the harvester. No more sore necks for the operators. I got the video from the Dutch manufacturer. Check out their site if you are interested in other very special machines for watercourse maintenance. www.conver.com
