Re: [Aroid-l] Syngonium

From: "D. Christopher Rogers" <branchiopod at gmail.com> on 2018.09.14 at 14:29:43 I have found S. angustatum to be common in Guam, Thailand, Laos, and Taiwan . . . but I also thought it was S. podophyllum. Thanks for the corrections and explanations Eduardo!! Happy days, Christopher On 14 September 2018 at 08:52, George Yao <geoyao@gmail.com> wrote: Thank you very much, Eduardo!

I don=E2=80=99t have pictures of synandria in S. podophyllum, but I am attaching a exert of Schott=E2=80=99s 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.=C2=A0 If you google S. podophyllum, all you see is S. angustatum!!!=C2=A0 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 =C2=A0in Mexico and once in Costa Rica. They can be common locally, but I doubt someone have the real S. podophyllum in cultivation.=C2=A0 Very best wishes,=C2=A0 Eduardo.=C2=A0 <PastedGraphic-1.tiff>=C2=A0 On 12 Sep 2018, at 08:41, The Silent Seed <tylus.seklos@gmail.com> wrote: Good morning Tom, Thank you very much!

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=E2=80=99s 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.=C2=A0 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 - =C2=A0climber like crazy and have softer leaves.=C2=A0 By the way, I have checked my S. auritum in my backyard and they have exactly the same aspect as that on Peter=E2=80=99s picture.=C2=A0 Very best wishes,=C2=A0 Eduardo.=C2=A0 On 11 Sep 2018, at 02:50, Peter Boyce <phymatarum@gmail.com> wrote: here in cultivation auritum has leathery glossy leaf blades while podophyllum has thin matte leaf blades. This is auritum (not my image) On Tue, 11 Sep 2018 at 09:27, Jason Hernandez <jason.hernandez74@yahoo.com> 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.
