Clubbing is an enlargement of the ends of the fingers and a downward sloping of the nails. Although it's not caused by chronic obstructive pulmonary disease (COPD), it can be a sign of coexisting lung cancer or other lung disorders in patients with COPD. Clubbing is sometimes called digital clubbing. It can affect the fingers and/or toes.

Kapok Tree (Ceiba pentandra). A giant in the rainforests, the kapok tree can reach up to 200 feet in height, sometimes growing as much as 13 feet per year.Due to its extreme height, the kapok, or ceiba tree, towers over the other rainforest vegetation. The trunk can expand to nine or 10 feet in diameter.In the nooks and grooves of this huge plant live a diverse number of species including frogs, birds and bromeliads.he kapok tree is deciduous, shedding all of its leaves during the dry season. As its seeds are easily blown into open areas, kapok trees are some of the first to colonize open areas in the forest. The white and pink flowers of the kapok tree emit a foul odor that attracts bats.
