A mysterious Syagrus

A mysterious Syagrus

Fifteen years ago, I bought a Syagrus vagans seedling at the FTG, growing up it became clear that it was something else. The palm has three uncommon characteristics among the Syagrus (see Noblick L. R. – A Revision of the genus Syagrus): long pseudopetiole and petiole (the latter 51.9 ± 5.8 cm long), fruits (L = 4.5 ± 0.42 cm; Ø = 3.3 ± 0.2 cm) with split tips and endosperm with internal cavity. No species, as far as I know, has these characteristics at the same time, from the name given by the seller and the long petioles it is likely a hybrid of the vagans, the only known is the x matafome, but it does not seem to correspond. The species that present at the same time split fruits at the apex and hollow endosperm that are similar in other characteristics to my palm are S. kellyana and S. picrophylla.

Thanks for any suggestions.

You might try contacting Larry Noblick directly. I believe he is still at Montgomery Botanical.

Thanks Kim,  I will, although I think he is very busy in his research work.

Very nice documentation indeed. Fine work. I looked a those two mentioned ( Kellan, picrophylla) and see differences. One is what I think you mean by pseudopetiole. Just to be clear, what is a 'pseudopetiole'?

Thanks! I meant the part of the stem of the leaf with the fibrous margins, but it seems that now we prefer to call the whole stem petiole.

It was a great surprise for me to receive a very kind reply from Dr. Noblick after a few hours, which I sincerely thank. For the long peduncles of the inflorescences, the fibrous mesocarp, the splitting fruits and the central cavity of the endosperm, he believes it is Syagrus lorenzoniorum.

I felt sure, with your detailed examination and documentation, that Larry would respond to you. He is a very kind person and generous with his knowledge.

Actually this term is frequently in use for the definition of the leaf rachis on Phoenix spp, which is equiped with acanthoPHYLLS  aka spines. People commonly do not consider the spines as simply modified leaflets and therefore they do not consider this part of the rachis to be strictly such. But technically it neither part of the petiole and hence the term pseudopetiole.
