Plants

Castanea sativa sheds its leaves in the unfavourable season and can grow into a large tree. The Castelo Branco Polytechnic profile describes narrow yellow flowers in long hanging spikes. Later, chestnuts develop together inside a prickly burr: the chestnut is the fruit, while the burr encloses the cluster.

Notice the layers: the shiny brown covering belongs to the fruit; inside there is usually one seed, with a yellowish skin. The tree also had a place in workshops: the source mentions wood used in carpentry, cabinetmaking, basketry and woodturning. These are general characteristics and uses, without attributing a workshop or individual tree to the municipality.

Flowers come before the burr. UTAD’s Digital Flora gives May and June as the species’ flowering period. This is a general botanical reference, not a prediction for a tree in Cabeceiras: compare photographs of the same tree on different dates to learn its rhythm. A tree without chestnuts on a spring visit tells a different story from an open burr in autumn.

Chestnut belongs to the Fagaceae family, the same broad botanical family as oaks. Comparing their fruits shows that kinship does not mean identical appearance: return to the oak story and look for what surrounds the acorn, then revisit the chestnut’s layers.

The Betula celtiberica profile describes a deciduous tree with a silvery-white trunk and leaves ranging from oval to triangular, with toothed edges. The species is associated with moist environments, including watercourse banks, and needs plenty of light.

The Gulbenkian Garden presentation places flowering in April and May and describes small winged fruits dispersed by wind. Bark, leaves and reproductive structures offer different clues throughout the year. This information concerns the species; it does not confirm its presence in a parish or guarantee the same dates everywhere.

Male and female flowers occur on the same tree but in different structures. Gulbenkian describes male flowers grouped in greenish-yellow catkins and female structures that are upright at first. A flower does not always have large, showy petals: observing a tree may require attention to discreet structures.

The profile also highlights shallow, horizontally spreading roots and the ability to produce shoots from the stump. The visible trunk is only part of the plant; growing from seed and producing new shoots are distinct processes. These are features from the Betula celtiberica profile, without attributing a particular tree to Cabeceiras.
