Sliding crops · olive trees
One leaf, two faces
On the half slopes of Cabeceiras, the municipal portrait includes olive trees. The cultivated olive tree has grey-green leaves on top and silver-gray under it, where there are hair. The small flowers feature four white petals attached to the base. The fruit is olive, an oil-rich drupa. The description of the University of Évora follows the change from green to reddish and dark shades during maturation, but refers to variants that remain green even mature. Color alone doesn't tell the whole story of the fruit. From the tree to the olive oil, there is a link that can continue in reading about the Ramil mill. The record distinguishes the cultivated olive tree from the wild variety, the zambujeiro. The latter describes smaller leaves and fruits and thorny lower branches. The comparison shows why a single feature, such as the silvery leaf tone, does not solve all the differences. The olive tree is perennial: it maintains foliage throughout the year. This allows you to return to the same tree at different times and compare leaves, flowers and fruits without expecting all to be present simultaneously.

Vamos experimentar?
- Observes the photograph: draw the contour and the central nerve of the sheet.
- The image does not show the two sides of the same sheet. Separate what you see from what the text explains on the lower face.
- If you observe an olive tree throughout the year, record separately leaves, flowers and fruits, without taking off material.
