Re: [Aroid-l] Syngonium

From: "D. Christopher Rogers" <branchiopod at gmail.com> on 2018.09.14 at 14:29:43(24076) 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 HTML +More On 14 September 2018 at 08:52, George Yao wrote: Thank you very much, Eduardo! It is quite a weed here in the Philippines. It can cover a wall in no time. I appreciate your shedding light on this long-standing misidentification. 👍 George Yao Metro-Manila Philippines On Sep 14, 2018, at 9:02 PM, Eduardo Gonçalves wrote: Dear George, Like all material people say is S. podophyllum, you are a proud owner of a S. angustatum.

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.

On Tue, 11 Sep 2018 at 22:26, Eduardo Gonçalves wrote: 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.

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.
