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

From: "Pacific Rim" paige at hillkeep.ca> on 2005.08.25 at 21:16:27(13322) Hello again, Pete. If the plant in my "elonagatum" slot is not elongatum, what is it, please? For that matter, are the top picture and bottom one in that slot of the same taxon? I was very surprised when the beautiful purple creature in the lower picture emerged from the ground. The spadix reaches almost to the top of the spathe in the upper photograph. I have some young plants from seeds collected wild at several sites in Turkey, sent by a generous stranger who had seen my web page. I will happily submit pictures to you for ID as these plants mature. Having blithely put your book on my Christmas list, I discover that it is very hard to come by. I will inquire about this in a separate email.

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!

I received your answer this evening, Peter. Thank you for your help. Group, what do you think? Many horticultural selections of A. dioscoridis have lost their taxonomical distinction and been wrapped into one variable species. Fine. But given that so many of the arums in horticulture are clones, is it not perhaps useful to repeat their former names, e.g. "This is the plant formerly known as var. spectabile"? Or does that just defer understanding that variation is the norm? As for my elongatum glitch: Thank you for confirming it, Peter. It's interesting how the mind keeps sifting. Already by this morning, my sleeping brain had signalled, "Ah-ooga, ah-ooga!" Looking at my web page, I realized that I had mixed up the images of nigrum and elongatum, and reposted the page. Peter, do other growers plague you with requests for names? If my orientale is orientale, some of the other orientales online must be something else. I spent months in Borneo in the early 1980s, but was focused elsewhere. Failed to differentiate the orchids or the Araceae. Thought of them all as plants.

Yes, "The Genus Arum" is on my Christmas list. But meanwhile, if anyone would like to comment, on or offline, about the identity of any of the Arums on my website at http://www.hillkeep.ca/bulbs%20arum.htm, I would be grateful. I am open to corrections on every ID, but the ones that particularly worry me at the moment are: -- "Arum aff. concinnatum." Should this be concinnatum? -- all the A. dioscoridis group. -- A. orientale. The photo is of the plant. But does it look like orientale? If not, what do you think it is?
