Peconha

For trees smaller than ten centimeters in diameter, a climber can use an adjustable loop called a peconha in Brazilian Portuguese. A peconha was traditionally made of bark fiber, but is now made of canvas.The climber places it around his feet, grips the tree with both hands and his looped-together feet, and essentially hops up the tree.

Thus, everything from the calyx to the articulation and from the articulation to the rachis is called the pedicel/hypanthium. |

Pedicel/hypanthium tapered to articulation
|
The pedicel/hypanthium is tapered gradually to the ariculation such that a true pedicel appears to be present |

Pedicel/hypanthium truncate at articulation
|
There is no clear cut pedicel in this type of pedicel/hypanthium |
