"According to Arisaema specialist dr. Jin Murata, this plant represents Arisaema bockii. They are certainly what Pampanini published as Ar.engleri. Murata puts Ar. engleri as a synonym to Ar. bockii. In that case, this plant is a purple form of Ar. bockii." W. Hetterscheid, 4/20/99
"According to Arisaema specialist Dr. Jin Murata, this plant represents Arisaema bockii. Guy Gusman thinks it is Ar. amurense, looking like Korean forms of this species he himself collected. Whatever it is, it seems to be a green form of the purple spathed Ar. bockii/engleri elsewehere on this page. Murata doesn't agree with Gusman's opinion that this is Ar. amurense but has yet to explain why. Gusman thinks Ar. bockii cannot be reprresented by this plant for several reasons. It all boils down to a taxonomic interpretation of the rather incomplete holotype specimen of Ar. bockii." W. Hetterscheid, 4/20/99
