Re: [Aroid-l] Intrageneric crossing?

From: "Peter Boyce" botanist at malesiana.com> on 2006.01.21 at 08:40:18(13748) Hi Julius I've looked at the Aglaonema/Dieffenbachia cross and am suspicious. I posted onto aroid-l but it's not popped up as yet. What I wrote was: +More "FolksI'm inclined to agree with Wilbert about the top and bottom image; certainlythe leaf emergence of the top image and the venation on the bottom look'wrong'. In fact, I'd go so far as to say the bottom image reminds mestrongly of a member of the Rosaceae, Photinia x fraseri.The middle image I'm not so sure about - to my eyes there are two 'aroidish'inflorescence/infructescences in the middle of the leafy crown. I've triedenlarging the image but he quality is too poor to reveal anything definite.Aglaonema and Dieffenbachia are a fair distance apart in terms ofrelationship. Curiously, if someone posted a claim of a Aglaonema x Anubiasor Aglaoneama x Nephthytis hybrid (or indeed Dieffenbachia x Gorgonidium!(sorry Eduardo!) I'd be a lot less sceptical.Pete" ----- Original Message ----- To: Sent: Saturday, January 21, 2006 7:59 AM Subject: Re: [Aroid-l] Intrageneric crossing? > >>From : Peter Boyce > Reply-To : Discussion of aroids > Sent : Friday, January 20, 2006 10:49 PM> To : "Discussion of aroids" > Subject : Re: [Aroid-l] Intrageneric crossing?> > I know that you are speaking about a Colocasia X Alocasia cross, not the > other shown in the photos.
