Philodendron fragrantissimum (Hook.) G.Don - Araceae - shortstem philodendron

Hemiepiphyte native to the New World Tropics; rosettes at maturity; petioles green, fleshy, concave above and convex below , 30-70cm long; leaf limbs obovate-triangular, base round or cordate, green, 22-60cm long; inflorescence peduncle pink, 5-8cm long; spathe purplish-red at the base (below the constriction) and cream or light pinkish in its upper portion; fleshy fruits (berries) bright red when ripe.

"The inflorescences of P.fragrantissimum are composed of an 8-11cm white spadix and a 10-13cm spathe which is white-coloured above the constriction and reddish below. The spadix is composed of a zone of pistillate flowers within a floral chamber and another of staminate flowers, separated by sterile staminate flowers... 
During the female phase of anthesis, the spadix heat production was synchronized with the emission of volatile organic compounds (VOCs) perceived by the untrained human nose as a pleasant and intense white floral fragrance." \\
Main components of the floral scent of Philodendron fragrantissimum from four inflorescences collected with two different sampling methods (dynamic headspace/SPME fiber) were methyl benzoate (71.7/24.7%), dehydrojasmone (21.2/37.2%), and (Z)-jasmone (6.3/27.4%). Minor components were e.g. benzylalcohol (0.06/0.05%), methyl salicylate (0.13/1.04%), and methyl jasmonate (0.29/9.04%). \\

"Finally, the floral scent of P.fragrantissimum is dominated by methyl benzoate (~72%), also identified as a minor constituent in four other investigated species, and isojasmol [(Z)-3-methylene-2-(pent-2-en-1-yl)cyclopentan-1-ol] (~21%), a jasmone derivative exclusive to this species. Due to a typing error, this compound was misidentified as dehydrojasmone in a recent published characterization of the floral scent chemistry of P. fragrantissimum (Gibernau et al. 2021)." \\
