Syagrus emasensis?

Dr. Larry Noblick is who you want to ask--you can get his email from the Montgomery Botanical Center website or even the IPS website, I am sure. He is a wonderful person and is the #1 expert when it comes to Syagrus. He also speaks Portuguese, fluently.

Dear All

In this region of Brazil, among the short-stemmed or dwarf species, I would expect to find Syagrus emasensis or Syagrus procumbens, both of which have been collected from the Parque Nacional das Emas. Both have spike inflorescences. 

My guess is that this specimen is most likely Syagrus procumbens. It has a leaf rachis or mid-rib that is clearly much shorter than its leaflets. The palm is also about the right size for that species, growing typically larger than Syagrus emasensis.

P.S. You can check this for yourself in my revision of Syagrus, which is well illustrated and is a free download from the following link:

very interesting download thank you

UPDATE:

Mauricio sent me a leaflet sample and anatomically his Syagrus is most closely related to Syagrus menzeliana. It is not S. emasensis nor S. procumbens. Syagrus menzeliana is from the same region, but has only been collected south of Mineiros and south of the Parque Nacional das Emas.  

For now I can only say that it is closely related to S. menzeliana, which is an acaulescent species that is larger than either S. emasensis or S. procumbens..
