The upper part of the former (not figured) resembles the lower part opinion that insects visiting the inflorescences only effect crossing, and do not serve as nourishment for the plant, as the necessary secretory organs are absent from the inflorescences, and the fly-larvae developing in it live for some time. 944.

Amorphophallus Blume. 2921. A. Rivieri Dur.—Pirotta (Nuovo Giorn. bot. ital., Firenze, xxi, 1889, p. 156) says that a plant of this species cultivated in the Rome Botanic Garden is necrocoleopterophilous, for 122 carrion-beetles were once found in the inflorescence, these belonging to nine species and six genera: Saprinus nitidulus F. (65) was the most numerous, and S. aeneus F. (30) came next. 2922. A. Titanum Becc. (Beccari, Bull. R. see. tosc. ort., Firenze, xiv,.
