Actually they are quite far away from orchides. The only thing they have in common, regarding to classification, is that they are in the clade of the angiosperms, which are the flowering plants in general ^^ but actually this special species of the Polygala looks really similiar to orchides.. Also the family of the Orchidaceae (orchides) are native everywhere in the world. The family of the Polygala is only there in South Africa 😉
