Name Origin:
Out of gratitude, Claudel chose to name this particular cultivar in honor of a friend and his encouraging help.
Growth Habit:
Tuber depressed globose, to at least 24 cm in diam. and to 15 cm in height, weighing ca. 6 kg, surface whitish-brownish with many raised areas, no offset development.
Leaf Blade:
Leaf solitary; cataphylls to 50 cm long,brownish, with white lichenlike spots; petiole to 1.45 m. long, to 8 cm in diam. (base), turgid, smooth, dark green or brownish, with large, whitish lichen-like spots similar to the ones on the petiole of A.titanum; lamina to 1.20 m in diam., poorly dissected in young plants, resembling a young A. titanum lamina, highly dissected in mature plants, showing more resemblance with a typical A. variabilis leaf; leaflets elliptic-lanceolate, to 20 cm long, to 7 cm in diam., acuminate, leathery, upper surface slightly glossy.
Bloom and Fruit:
Inflorescence solitary; peduncle to 55 cm long, ca. 6 cm in diam., coloured as petiole but darker altogether; spathe campanulate, triangular, to 45 cm long, limb spreading, rim-shaped, margin slightly plicate similar to A. titanum but not as strong as in the latter, veins of the limb strongly raised, outside base dirty greenish yellow with whitish spots, base
inside verrucate and slightly purple at the base, with abroad yellowish band above and rich purple-red in the upper part. Spadix sessile, longer than spathe, ca.1 m long; female zone 6 cm long, flowers congested; male zone slightly obconic, 8 cm long, flowers congested like in A. variabilis; appendix elongate fusiform, obtuse, ca. 80 cm long, ca. 9 cm in diam.,base truncate and expanded overarching the male zone, similar as in A. titanum, dirty yellowish white, slightly rugose. Ovaries ovate, ca. 5 mm in diam., 3 mm high, orbicular, base yellowish, turning purple in the upper part; style 5 mm long, blackish purple; stigma elliptic, 1–2 mm in diam., ca. 1 mm high, orange, strongly bilobate. male flowers producing abundant pollen. Pollen fertility unknown. Propagation by vegetative means.
Distinguishing Characteristics:
A rare hybrid between Amorphophallus titanum and Amorphophallus variabilis, combining the bold scale and mottled petiole of titanum with the finer, highly dissected foliage and dense floral structure of variabilis.
