Re: [Aroid-l] Please help me with Arum IDs

Hi Paige
 
Glad that I was able to be of help.
 
To tackle your points one-by-on:
 
dioscorides: The main problem is that in cultivation what folks are calling, e.g., cyprium, mostly do NOT match the original A. cyprium (which has a yellow-green spathe with discrete very deep purple spots and no spathe staining/flushing) and thus there is a double problem with scientific names are being misused as cultivar tags AND are being misapplied!The neatest answer with A. disocorides will be to recognize cultivars for the more distinct & stable colour expressions.
 
elongatum: when I looked yesterday there were no images of true elongatum on your web - the images under nigrum  were nigrum. The crucilal elongatum character is that the spadix appendix reaches to the tip of the spathe.
 
 orientale: Most on-line images are NOT orientale. Some are besserianum, some are gratum, a few are maculatum, one or two are cylindraceum (the new name for alpinum), yet others are italicum...
 
I get about a dozen identification requests a week by email and about the same a month by letter. I LOVE doing ids. Keep 'em coming!
 
Very best wishes
 
Pete
