Re: A. sazensoo


Jan,

Some mistakes die hard. 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
      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.
