The oncidium in the garden bloomed beautifully, attracting many visitors.
Oncidium is derived from the Greek word "onkos" (meaning swelling or mass) and the suffix "-idium" (a diminutive suffix in Latin). The term refers to a type of orchid characterized by its swollen pseudobulbs, hence the name.
Think of 'onkos' meaning swelling, which helps you remember that 'oncidium' refers to orchids with swollen parts.
