Spigelia genuflexa

Another new species from Brazil today! BPotD reader Gary Zamzow alerted me to the recently-described Spigelia genuflexa, published (as of yesterday) in the peer-reviewed, open-access journal PhytoKeys: Popovkin AV, Mathews KG, Santos JCM, Molina MC, Struwe L (2011). Spigelia genuflexa (Loganiaceae), a new geocarpic species from the Atlantic forest of northeastern Bahia, Brazil. PhytoKeys 6:47-65. doi: 10.3897/phytokeys.6.1654.app4 .

First discovered by José Carlos Mendes Santos, a handyman in rural northeastern Bahia of Brazil, these diminutive plants on the property of amateur botanist Alex Popovkin were photographed and collected by Mr. Popovkin over the course of the past couple years. All of today's photographs are courtesy of Alex, via Flickr (his photostream: Alex Popovkin, Bahia, Brazil@Flickr). Original images for today's posting are here, here, and here, and these are part of a much larger set of images by Alex: Spigelia genuflexa.

In the course of trying to determine what species this might be, Alex communicated with taxonomic experts from around the world. The evidence seemed to suggest this was perhaps a new species. With the aid of taxonomists from Universidad Rey Juan Carlos and Rutgers University, the work in establishing it as a new species (through comparisons with previously described species, including phylogenetic analyses), Spigelia genuflexa was recognized and published.

Spigelia genuflexa is unique among the known members of its genus for being geocarpic: (from the article) "During fruit maturation, the basal infructescences bend down towards the ground, depositing the fruit on the surface (and burying it in soft kinds of ground cover, e.g., moss), whereas the upper ones do so slightly but noticeably." I can recall only one other species with this property previously featured on Botany Photo of the Day, Pseudotrillium rivale.

Only a few small populations are known for this species, all restricted to the sandy leaf litter- or moss-covered soils of the Atlantic tabuleiro forest of Bahia. Growing to 25cm (though initially discovered with plants only 3cm tall), it is a short-lived annual.

To read the press release surrounding the discovery, see "Amateur botanists in Brazil discover a genuflexing plant".

Very sweet plant and a wonderful story (here and at the link). The kind of story that makes me very hopeful. And another botanical term learned. Great post.

Mary Hamilton commented:

The pictures are great,but!
How does one enlarge the text? to be legible???

Jean Hoffmann commented:

To Mary Hamilton,

I'm not a computer expert, but I have learned that pressing the Ctrl and + keys together enlarges any text on the internet. Each time you press the keys together the text enlarges again, so you can do this as much as you need.

To get the text back to the original, press Ctrl and -, the same number of times.

Hope this helps!

And thanks for the sweet plant posting.

Connie commented:

I laughed when it seems like the plant plants its own seeds. Plants are so amazing!

Irma in Sweden commented:

to Connie
I thougt it was a cyclamen which also has the habit of burying its seeds

sergioniebla commented:

Qué hermosura de planta y muy buena foto!! ... Felicidades José Carlos Mendes Santos....

*rob* commented:

inflorescences that flower and then bend down to bury their seeds also sounds like what peanuts do, right?

Daniel Mosquin commented:

That's right, but peanuts have yet to be featured on BPotD!

elizabeth a airhart commented:

if we but look we shall see bravo to one and all
will the little darling's seeds go into a seed bank somewhere?
thank you for shareing with us

Stassia Samuels commented:

Scoliopus bigelovii, "fetid adder's tongue", a very cool, foul smelling relative of Pseudotrillium rivale found in northern California, does the same thing. Wonderful!

Diana Ferguson commented:

This is beautiful and so exciting to see a new species. Thank you so much for this one!

Deb Lievens commented:

I can't live without BPotD for botanical reasons, but you never know what you'll find. Jean's computer hint "control + " will probably make a greater impact on my life than some of the botanical education. Thanks. But learning the term "geocarpic" does still rank amongst the best.

Dana commented:

I LOVE this site! You are supposed to Learn Something New Everyday, and I learned the term for what peanuts do to make fruit is "geocarpic" - It makes sense, geo=earth and carp=fruit.
Shame on you Daniel for not highlighting something as cool as a peanut yet! Oh wait, they grow in Georgia in the US and you are in British Columbia, not exactly a peanut's favorite choice in climate...

elizabeth a airhart commented:

i live in the usa the little peanut seeds go right in side
little glass jars where they grow into peanut butter
how did you think you could have peanut butter
off your grocers shelves

phillip commented: quit tellin those tall tales...every knows that the only thing grown in a jar is a tomato..that's where we get catsup..

swamprose commented:

This is a wonderful story, as well as a terrific new botanical discovery. High five for amateur botanists! and the internet.

Ruth commented:

New favorite plant! Looking forward to the peanut story and the shocking news about its masquerade! GO BPotD!!! from Melbourne, Australia.
