Translation:

29. Among Talh trees with flowers (or fruits) piled one above another

Notes (Tafseer)

5238. Talh: some understand by this the plantain or banana tree, of which the fruit is borne in bunches, one tier above another; but the banana tree does not grow in Arabia and its ordinary Arabic name is Mauz; perhaps it is better to understand a special kind of Acacia tree, which flowers profusely, the flowers appearing in tiers one above another.
