The adventitious roots of a mature vanilla vine serve both as supports and as absorptive organs. The supportive aerial roots are short, glabrous and unbranched. They adhere strongly to the supports by means of short epidermal hairs formed opposite them. The terrestrial roots are long, hairy and branched and grow in the leaf litter. The short supportive roots and the aerial portions of the terrestrial roots have thick-walled dermal tissues to limit evaporation. The terrestrial portions are relatively thin-walled. The persistent epidermal hairs of the uniseriate epidermis function as a velamen. Crystal-bearing idioblasts are most conspicuous near the root tip where they may have a protective function in limiting fungal and other infections.
