Leaf of Pavetta gardeniifolia

Summary

edit
Description
Afrikaans: Nabyskoot van 'n Kersbruidsbos-blaar (Pavetta gardeniifolia subsp. gardeniifolia) te Krokodilrivierreservaat, Gauteng. Die plant was binne 'n boomgroepie met Karee (Searsia lancea) wat die baldakyn vorm, in andersins oop grasveld. Hierdie subspesie het haarlose blare en kan daaraan uitgeken word. Die spesie, soos naverwante, het bakteriese knoppies in die blare, wat opval as verspreide donker kolle in die blaarblad as dit teen die son gehou word. Die knoppies bevat 'n spesie-spesifieke bakterie (Burkholderia sp.). Hierdie Pavetta-spesie besit egter nie domatia soos sekere naverwante nie, nóg enige sekreetholtes wat vlugtige olies vrystel.
English: Close-up of a leaf of a Christmas bride's bush (Pavetta gardeniifolia subsp. gardeniifolia) at Crocodile River Reserve, Gauteng. It was growing in undergrowth of a bush clump, with Karee (Searsia lancea) forming the canopy, in otherwise open grassland. This subspecies has glabrous leaves, and can be identified thereby. The species, like near relatives, has bacterial nodules in the leaves, which show up as scattered dark dots on the leaf blade when held up against the sun. The nodules contain a species specific bacterium (Burkholderia sp.). This Pavetta species does not have domatia like some near relatives, nor any pellucid gland dots that secrete volatile oils. Observed during an outing of the Tree Society of South Africa.
