Re: [Aroid-l] Syngonium

From: Tom Croat <Thomas.Croat at mobot.org> on 2018.09.12 at 04:56:19(24068) Dear Jude: I have to assume that this variegated form is just an unusual form of Syngonium podophyllum Schott. I think that most of the cultivars have arisen from that species but the juvenile forms of all Syngonium are somewhat subject to doubt since one never really knows who creates these thing and from what source.

Best, Jude On Tue, Sep 11, 2018 at 12:43 PM, Tom Croat wrote: I agree with Eduardo. Syngonium angustifolium is much more of a weed than S. podophyllum. I remember that it was adorning the trees of the public circle in Balboa when I was working on my Revision of Syngonium and I had not found it anywhere in the wild at that time in Panama. Many neotropical aroids have been introduced in to the natural forests of Papua New Guinea. I was shocked to see so many such species in what I thought was virgin forests around Lae.

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.

This is auritum (not my image) On Tue, 11 Sep 2018 at 09:27, Jason Hernandez wrote: 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.
