Thanks Colin. 
Not sure if engleri has both bisexual and "female only" plants or not. Do you know?
The Gusman book has a reference to 7 leafed forms (as the illustration in the book shows on page 281, with leaves 6 and 7 being small) but evidently also there are 5 leafed forms of this species. Looking at the shapes of my leaves in the photo and comparing to the book illustration, these leaves shapes resemble engleri more than any other species in the large Pistillata Section.
And because it came from Chen Yi, very unlikely it would be anything except a Chinese species, as I now understand those plants were mostly wild collected. Most species in that section are Japanese while 2 are North American (triphyllum, quinatum).

Subject: [Arisaema-l] confirming ID of Chen Yi A-28  I have grown this plant since 2007, originally ordered from Chen Yi Nursery in China as A-28 (they IDd it as A. sikokianum var. serratum, but we know their IDs are often wrong).   The first picture taken April 7th is a bit out of focus on the bloom, but shows shape and color. Second one I took of the leaves today from above. The plant has finally decided to make what might be a viable seed pod if it survives till fall. I expect I might have enough to share with the AEG seed exchange but want to make sure of the ID.  I was told by a friend that this Chen Yi number is A. engleri, and that is consistent with the ID table that the group has where in 2000 Bonaventure Magrys posted some pictures of his A-28 blooming potted plants on the site and Guy Gusman confirmed that they were engleri.   At first I was hesitant that mine was engleri as my blooms (and this year's seed pod) are always held UNDER the leaves, unlike Bonaventure's picture,  but then I read in my Gusman book (p. 291) that the blooms are above the leaves in male plants, but at or under leaf level in female plants. To my knowledge, this is the only possible A. engleri I have. Would there need to be both male and female for seed production in this species? I know that this is not required for others.   Can anyone confirm that this is in fact Arisaema engleri? At the top of page 291 of the Gusman book he says it is sometimes called A. sikokianum, var. serratum.   Thanks.  Charles HunterSmyrna, Georgia USA
