 Inflorescence Terminology (Part 1)
The spadix is the characteristic inflorescence of the remarkable arum family (Araceae).
In some species in which the upper part of the spadix is sterile (flowerless), the heat mechanism appears to be in the cells of this sterile tissue.
Spadix: A thick, fleshy spike of unisexual, apetalous flowers, often surrounded by a vase-shaped or funnel-like modified leaf or spathe which is often brightly colored.

 Pollination of Philodendron solimoesense
The pistillate flowers occupy the lower portion of the spadix and take up ~20% of the total length of the inflorescence, whereas the male flowers are located on the upper portion and occupy ~30% of the total length.
In the median portion of the spadix, there is a prominent intermediate zone (~50% of the total length of the inflorescence) consisting of sterile male flowers (picture 3).
The spathes opened in the middle of the morning of the "first-day", revealing the spadix, and were wide-open during the afternoon with an extremely curved white spadix (about 45° towards the exterior, Figure 4).

 spadix
Flowers lack a perigon and are closely arranged on a more or less cylindroid spadix with the staminate flowers comprising the upper 2/3 to 4/5 of the spadix and the pistillate flowers comprising the remaining basal portion.
The average length of the longest spathe for is 16.5 cm while the average length for the longest spadix is 15.8.
The differences in the length of the adaxial and abaxial surfaces of the pistillate spadix depend on the angle at which it is attached to the spathe.

In monoecious aroids (possessing separate male and female flowers, but with both flowers present on one plant), the spadix is usually organized with female flowers towards the bottom and male flowers towards the top.
In aroids with perfect flowers the stigma is no longer receptive when the pollen is released, thus preventing self-fertilization.
