I was shocked to see so many such species in what I thought was virgin forests around Lae. =C2=A0 Tom =C2=A0 From: aroid-l-bounces@www.gizmoworks.com [mailto:aroid-l-bounces@www.gizmoworks.com] On Behalf Of Eduardo Gon=C3=A7alves Sent: Tuesday, September 11, 2018 9:23 AM To: Discussion of aroids <aroid-l@www.gizmoworks.com> Subject: Re: [Aroid-l] Syngonium =C2=A0 Dear aroiders,=C2=A0 =C2=A0 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=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 =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 =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 =C2=A0 Very best wishes,=C2=A0 Eduardo.=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 On 11 Sep 2018, at 02:50, Peter Boyce <phymatarum@gmail.com> wrote: =C2=A0 here in cultivation auritum has leathery glossy leaf blades while podophyllum has thin matte leaf blades. =C2=A0 This is auritum (not my image) =C2=A0 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. =C2=A0 Jason Hernandez _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l <6850591_13153.jpg>_______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l =C2=A0 _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l -- The Silent Seed Rare and Unusual plants from around the world.=C2=A0 thesilentseed.com --000000000000815aa005759d112b-- --000000000000815aa305759d112d
