Term used to name compound leafs with several leaflets that open like a fan from a common point, with the format of a flat hand. E.g., buckeyes.

Generally the most showy part of the flower. Petals product the core of the flower and, when colorful, serve to attract pollinating insects towards the stamens and pistils. A flower can present few petals, like the flowers of several dayflowers, with only 3 petals) or several (like roses). The group of petals in a flower is called a corolla.

Connecting stalk between the leaf blade and its point of insertion in the stem or branch.
Symbol to express the level of acidity, on a scale of 0 to 15, in which 7 represents neutrality (equilibrium between acid and alkaline). Values higher than 7 represent increasing alkalinity, and below increasing acidity. To have an idea, vinegar has a pH around 3 and sodium bicarbonate a pH around 8. Ornamental plants usually require a pH between 6 and 7.5 (each unit of Ph represents an acidity or alkalinity 10 times greater: a soil with pH 5 is ten times more acid that a soil with pH 6; a soil with pH 8 is 10 times more alkaline that a soil with pH 7).
Phalaenopsis is one of the most refined orchids, also known as Moth Orchid, or by the abbreviation Phal.

Got its name in homage to the Greek god Proteus.

Part of an epiphytic orchid’s stem with a bulbous aspect.
Pseudofruit (or Accessory fruit)
Structure that develops from flowers, but in fact does not develop from an ovary. Cashews, apples and quince are pseudofruits because they are not derived from the ovaries; strawberries, because they are derived from the several ovaries of a single flower; pineapple, raspberries and figs develop from different parts of several flowers.
