Dear Eduardo,

Ah HA - great stuff and MANY thanks for the clarification. Wooo it means that angustatum is a pestilential weed here on Borneo!

Very best wishes

Dear Pete, 

To me, those on your picture are quite retuse. I don’t have pictures of synandria in S. podophyllum, but I am attaching a exert of Schott’s S. vellozianum, which is quite similar to S. podophyllum except for the red-yellow fruit issue. The furrows between individual stamens are almost indetectable in S. podophyllum. 

If you google S. podophyllum, all you see is S. angustatum!!!  In fact, I have cultivated S. angustatum, S. erythrophyllum, S. auritum, S. chiapense, S. crassifolium and S. yurimaguense, but only saw S. podophyllum twice, once  in Mexico and once in Costa Rica. They can be common locally, but I doubt someone have the real S. podophyllum in cultivation. 

Very best wishes, 

Eduardo.

Hello Eduardo

So are these (see attached)  flat or retuse?

Dear aroiders, 

As far as I have observed, the Syngonium which is broadly cultivated is Syngonium angustatum, not S. podophyllum. The main easy-to-observe difference is on male flowers, which are retuse (shallowly lobate, like a molar teeth) on apex on S. angustatum and truncate (blunt) on S. podophyllum. I took this in Tom’s revision of the genus (1981). All naturalized Syngonium I have seen in Brazil and around Miami are S. angustatum. Pictures I have seen from Southeastern Asia are S. angustatum as well. 

Syngonium auritum has subcoriaceus and pretty shiny leaves and is a lazy climber, seeming to prefer to be lurking around on topsoil. Material I have seen of S. podophyllum - only in Chiapas-Mexico and around San Jose in Costa Rica -  climber like crazy and have softer leaves. 

By the way, I have checked my S. auritum in my backyard and they have exactly the same aspect as that on Peter’s picture. 

Very best wishes, 

Eduardo.

here in cultivation auritum has leathery glossy leaf blades while podophyllum has thin matte leaf blades.

This is auritum (not my image)

As long as we are on the subject of Syngonium, is there a reliable way to distiguish in the field between S. podophyllum and S. auritum? It matters because in the Dominican Republic, S. auritum is native, S. podophyllum is naturalized.
