These Viscum seeds have gone through the digestive system of some fruit eating bird, maybe a mousebird. The seeds were dumped here, sticky enough to cohere among themselves and to adhere to the shrub branch, presenting a new growth possibility.
At least one new nutrient-transferring attachment may be formed by the parasite seeds to access the juices of the prospective host, the probability high given so many seeds present. One seed is produced per Viscum fruit.
The seeds may be those of Viscum rotundifolium fruits. There are a few Viscum parasite species growing on shrubs at Minwater, the Little Karoo farm where the photo was taken. At this time there is no certainty as to the species from looking at the seeds, the situation to change once there is new growth from one of them (Van Rooyen and Van Rooyen, 2019; Vlok and Schutte-Vlok, 2015; iNaturalist).
