ABSTRACT: To follow-up the article in ‘Aroideana’ vol. 35, we want to document further attempts and progress in hybridizing Amorphophallus. We present more new crosses which have been successfully undertaken recently. Amongst them: Amorphophallus boyceanus 3 Amorphophallus ‘John Tan’ (see ‘Aroideana’ 35), the first Amorphophallus hybrid involving three species.

2014 37(1) 72-79 Cyrille Claudel, Ralph D. Mangelsdorff Hybridization of Amorphophallus — State of the Unions (Buy)
ABSTRACT: Following the articles in Aroideana vol. 35 and vol. 36 (referred to as vol. 35 or 36 in the further text) we document further attempts in hybridizing Amorphophallus. Although still far from being conclusive a few further observations are presented concerning the compatibility and the heterozygosity. Besides we want to add a new category in the ‘‘fail’’ and ‘‘success’’ column: the ‘‘albino’’.
