The general perception about orchid flowers is that of large flowers with spread open bilaterally symmetric sepals and petals. However, there are many orchid flowers that are tubular in characteristic. With either sepals or sepals and petals fused to form a tube like structure with only its apical ends free.
Botanically the process of fusion of like/similar parts is termed connation, and those fused parts are described as connate.
