Fruit & Flowers

The Virola pavonis tree bears a ellipsoidal fruit, 36-42 mm long and 30-34 mm in diameter.. The fruit appears to be nut like, with an outer shell with a reddish colored fruit inside. Before the fruit gets to this stage, it is a green unripe nut

 like in appearance. The Virola pavonis also is a flowing tree, having small reddish yellow flowering bud.

Leaves

The leaves of the Virola pavonis tree are in an alternate pattern, meaning the leaves spring one node at different levels of the stem. The veins of the leaf are pinnate
Pinnate
Pinnate is a term used to describe feather-like or multi-divided features arising from both sides of a common axis in plant or animal structures, and comes from the Latin word pinna meaning "feather", "wing", or "fin". A similar term is pectinate, which refers to a comb-like arrangement of parts...

. There is one main stem or midrib from which the other stems source from. The leaf is elliptically shaped with smooth margins (or edges). Also, the leaves of the Virola pavonis are stalked meaning the leaves have a petiole
Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

s of this fruit contain various neolingnas.
According to an abstract written by Marcia O.M. Marquesa, Massayoshi Yoshidaa and Otto R. Gottlieba for the Instituto de Química, Universidade de São Paul in March 1992,
"Virola pavonis was found to contain in the arils of its fruits 8.O.4′,7.O.3′-neolignans (eusiderins A, C and K) and a 8.O.4′-neolignan (of the β-propenylaryloxy-arylpropane type) and in the seed coats of its fruits 8.5′-neolignans (carinatone, carinatol) and 8.5′,7.O.4′-neolignans (dihydrocarinatin, carinatin). Some previous 13C NMR assignments for the latter four compounds are corrected."


The leaves of the Virola pavonis also bear some complex compounds such as DMT

as well as Pavonisol according to Pedro H Ferria and Lauro E.S Barataa;

"Pavonisol, a new C-1/C-2 oxygenated phenylpropanoid, together with the known eusiderin-E and an 8,4′-oxyneolignan, were isolated from Virola pavonis leaves. Their structures were established by spectroscopic methods and chemical transformations."
