Re: Identify this Amorph

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2000.09.07 at 14:26:58(5352) Miguel, The size of the leaflets of yuor plant is not a relevant distinction in paeoniifolius, of which this size varies considerably. I think your plant IS paeoniifolius after all. You ran into one of the few clones/cultivars that through the long ages of domestication of this species, has developed smooth petioles. In olden days, such forms were identified as "var. hortensis" and should represent clones with a lower amount of irritating oxalates in the tuber, making it more easy to refine for food production. The colour of the petiole is also not a relevant character, although, also in the past, the green colour was part of the identifiers of "var. hortensis'. However, there are numerous examples of green petioles with a very rough surface.
