A. sazensoo

From: jrenfroe at nvinet.com (Jan Renfroe) on 1997.01.02 at 21:27:06(32) Aroiders, I need help understanding something. I have spent a lot of time looking at the Arisaema Web Site and enjoying the beatiful pictures of Arisaema included there. Two of my favorites are A. sazensoo and A. sikokianum and I have spent a lot of time looking for sources of these two arisaema. Now I get my new Herswood catalog and find that in the description for A. sazensoo it says that their references list A. sazensoo is synonomus with A sikokianum. Now these two plants do not look anything alike to me from the pictures at the Arisaema Web Site. So I am really confused! The description given in the Heronswood catalog does seem to match the picture of A. sazensoo. So why would it be considered synonomus with A. sikokianum? -- Thanks, Jan Renfroe +More jrenfroe@nvinet.com

A hundred years ago some taxonomist equated A. sazensoo with A. sikokianum and his mistake gets quoted every so often. If you look at your Arisaema species list that you received in the Arisaema Enthusiasts information packet, you can answer your own question. you will see: A. sazensoo (Blume) Makino (in bold print signifying a valid species name with 2 valid forms) f. sazensoo +More f. viride others = f. sazensoo A. sikokianum Franchet & P.A. Savatier (in bold print signifying a valid species name with 3 forms) v. serratum (Makino) Hand. -Mazz. v. sikokianum Franchet & P.A. Savatier v. henryanum (Engl.) H. Li v. integrifolium = sikokianum It is not surprising that they don't look alike. They are entirely separate species. Jin Murata placed them as follows in his revision of the Japanese species (also available here) 24. Spathe blade widely ovate, ovate to oblong-ovate, fornicate, acute to acuminate, distinctly declined 25. Spathe blade longer than tube..........................................................A. sazensoo Blume ex Makino 25. Spathe blade shorter than tube........................................................A. kuratae Serizawa 24. Spathe blade obvate, not fornicate, cuspidate, erect or ascending.......A. sikokianum Fr. et Sav. Since he is the reigning expert on Japanese species, we have a definitive separation of the two. I'm not sure which keys you ordered. There are keys for Japanese, Chinese, Burmese, American, Himalayan, and Indian species all available to members for the postage. Ray GRSJr@Juno.com

Since we grow and have flowered both here, I can assure you that they are very different. The primary difference appears that the spathe tip hangs far down over the pitcher in A. sazensoo, while the spathe tip in A. sikokianum is held upright. There should finally be enough A. sazensoo in the country for all the patiently waiting collectors. -tony avent +More plant delights nursery raleigh, NC Tony Avent Plant Delights Nursery 9241 Sauls Road Raleigh, NC 27603 USA USDA zone 7, 0F-100F
