Petiole – The little stalk that holds the main blade of the leaf or leaflets. Rachis – The point at which all of the leaflets meet. They can also get a little stretched and look like little petioles themselves. Stem – The part of the plant that supports and gives rise to leaves and flowers; it joins the root system at the soil level.

The petiole develops last in the leaf and sometimes may not develop at all. A leaf with a petiole is petiolate (mango, etc.) and one without any is sessile (Calotropis, etc.). A petiole or leaf-stalk is usually solid and cylindrical but may be more or less flatt­ened, grooved and spongy as in banana or it may be hollow as in papaw (Carica papaya).
