Is this Scrophulariaceae species practicing carnivory

Allen Lowrie and I have been working on breeding a large selection plant species, many of which do not always relate directly to this CP forum but if you grow carnivorous plants the majority of these plants do make fantastic companion plants.


This particular Scrophulariaceae species shows signs it maybe be practicing carnivory which will be of interest to Pinguicula and Drosera enthusiasts.
This Scrophulariaceae species is a leafy, very floriferous, compact, branching, Mexican Pinguicula-like plant with its leaves densely covered with glassy Drosera-like glands that are capable of capturing small flying insects. Its solitary flowers are numerous and positioned just above the leaves. Its flower shape is Pinguicula macroceras-like but without the spur and upper petals of that species.

Photo 05, photo 06, photo 07 & photo 08: This species can catch small insects on any glandular part of the plant. Principally the adaxial and abaxial surface of leaves, flower stalks and the abaxial surface of petals and tube.
The viscosity of mucus is not as strong as that found in Drosera species or even that of Byblis guehoi to which it has been compared. The size of the prey this species captures is therefore rather small.

We are not exactly sure just what purpose the glandular covering on this species is used for.
Could its purpose be a means of gathering nutrients from captured prey; to defend against insect attack; or is it a self-watering adaptation used during the dry season, to collect water droplets from the moisture laden air during the early morning humid periods? Or is it a combination of any or all of these three adaptations?

Note how the motion of the flower stalks continually search for a place to position their seed capsules. The DNA code of this species seems to be designed to search for suitable locations where it can lodge its seeds into nearby cracks, ledges and fissures of a cliff face thus colonizing its vertical habitat.
We have proved that selected clones of this species from our breeding trials are very suitable for pot cultivation. They make an ideal potted colour species for sales in the florist and nursery trades.
The species may also be suitable for landscaping projects as well. Especially in regard to the decoration of large areas of brick, rock and block retaining walls. Landscape architects of the world may find this species the solution to adding living colour to the bare walls of their garden designs. This species preference for cliff face habitats make it a suitable candidate to be incorporated in their landscaping designs as spectacular vertical wall gardens. We can see a big future for this species in the hands of the world’s leading landscaping architects and designers.

In the younger flowers it appears only the pistil with its bilobed stigmatic tip is mature and active. The anthers at this time are not active and are hidden within a two lobed protective housing.
When the pollinator enters the flower: it triggers the pistil to rapidly swing upwards; gathering pollen grains on its stigmatic tips from the pollinator in the same motion; and finally positioning itself horizontally and well away from the pollinator. If the pistil fails to scoop-up pollen from the pollinator's body, the pistil will within 24 hours, reset itself and hang as before at the flower entrance ready for the next pollinator visit.
Later as the flower matures, the anthers push their two lobed protective housing apart, pollen grains are release and gathered together in a clump. The pollen package is now visible and hangs between and just below the two door lobes. The pollen is now readily available for pollinator deposits and transportation.
It appears a fully mature flower will not only accept pollen from a pollinator, but will also deposit its pollen on to the same pollinator as it exists the flower.
Note the 2nd well matured flower in the video: This pistil action suggests that if a pollinator touches the pistil strongly, the stigmas may come into contact with its own pollen. It appears this species could self-pollinate, but its design has a preference for out-crossing.

Its certainly going to a lot of effort and expending some valuable energy into producing so much mucus.

It must be for a reason,it looks very ping like.If its not carnivorous/insectivorous is it to stop it being eaten by animals,i.e foul tasteing or poisonous?

Interesting article. Just missed to say that the genus/species is this plant?

Best regards,

Very interesting plant, really looking like something between Byblis and Pinguicula. Where it is from (and whats its name)? Does it grow on poor soils? What about some tests of carnivory (e.g. proteinase test)?

Carnivorous or not, It looks great, and I seriously want to grow it!

Konnichiwa!

I will write details including the botanical name as soon as possible.

Please be patient for a while.

Dear Zlatokrt-san and Daniel G-san,

This species is easy to grow!

Kind regards from the far East

I know I FIN want one! i deffiantliy want one. I would say since you cant tell what medium it is growing in if it is a desert dewlling plant. Jungle and so on. what type pf soil is it in. it seems to have the glands for bugs. is this a new type of species that has yet to be discovred?

Only time will tell

At least this one looks possible as a carnivore.

What complicates it is that so far nobody gives details of this carnivorous plant :( . Even know what genus / species it belongs :wacko: !

Best Regards,

Rodrigo

Aha!! Now I'm understanding the beautiful picture you sent me a few weeks ago Takai-san! :) What an amazing plant and those two videos you made are marvelous, thank you so much!!

Good luck growing new and beautiful cultivars!

Hey Hi

does nobody know the exact botanic name?

This is really a beautiful plant i`d like to grow this year.

Guys, don't get too excited. Take a close look at the trapped insects--in no photos do we see them being digested. Rather they just hang in place. Unless something else happens latter on, these plants aren't carnivorous plants.

I searched a little bit and found this plant "Eremophila hygrophana".

Could this be a distant relation to the plant on the picture?

Is this the right species?

Hi

 

thanks for the interesting Youtube Links.

Have you got more informations about the plant and its growing coditions? Where is the natural habitat? How do you got the plant? The name would be also nice.

I think they are just taking it slow, so Allen didn't have to include this plant in and thus further delay his new books from coming out.  If he works on this species, he'd have to include it Carnivorous Plants of Australia, as that is most likely where this plant is from.

 

No, I don't think it can be a shrub from Eremophila.  It appears to be an herb with a pinguicula-style habitat preference!  Not a woody bush that grows out in the open under full sun.  That right there would place it outside Eremophila.  But perhaps in a genera next to it?
