Afrikaans: Sekreetholtes op die blaar van 'n Kaapse kastaiing wanneer dit teen sonlig gesien word, in die tuine van die Uniegebou, Pretoria. Die holtes staan uit as helder ronde ligkolletjies in die middel van die blaarpoligone. 'n Vlugtige aartappel-geurige bestanddeel word vrygestel wanneer die blaar gebreek word.
English: Secretory cavities (not secretory cells) on a Cape chestnut leaf held against sunlight, in the gardens of the Union Buildings, Pretoria. The cavities show up as round lucid dots in the centers of the leaf polygons, and in this species' case they produce a potato-like smell when crushed. Such leaves are described as "pellucid gland dotted", "pellucid punctuate", or "glandular punctuate".
