I always hesitate to identify a plant from one photo only. Anyway, the
Chinese A. engleri and the Japanese A. kuratae are close to each other,
but I doubt Ronken's plant is A. kuratae for the following reasons:

- 2. the spadix is cylindric and clavate in both species, ending in a
white apex, sometimes with some red dots. It is also more or less
exserted from the spathe-tube. The extremity of the spadix is not
capitate as much as in A. sikokianum, and A. sikokianum, itself is not
always that capitate!
- 3. No, in A. engleri the inner side of the tube can be white. I join a
photo of A. engleri that shows a spathe-tube whitish inside.
- 4. In both species, there is a white annulus at the base of the spathe-tube.
- 5. If A. engleri has leaves that are often denticulate, I saw
specimens with entire leaflets margins.
- 6. A. kuratae has a mouth-margins nearly straight.
The main differences are:
A. kuratae has a spathe with a wide, white central stripe along the
spathe-limb (see photo page 251, bottom left); it is very conspicuous as
seen from the outside. The spathe is always held well below the foliage
because the peduncle is much shorter than the petiole (see photo page
151).
