Vanda lamellata was collected in 1838 by Hugh Cumin near Manila , he sent live plants to the Loddiges nursery in England. The first description was also published in 1838 by John Lindley . The boxallii variety was not found until 1879, also in the vicinity of Manila. Further described varieties are Vanda lamellata var. Calayana and Vanda lamellata var. Remediosae , which, however, are used as synonyms for the aforementioned.
