Vanda sanderiana is a species of orchid. It is commonly called waling-waling[1] in the Philippines and is also called Sander's Vanda,[2] after Henry Frederick Conrad Sander, a noted orchidologist. The orchid is considered to be the "Queen of Philippine flowers" and is worshiped as a diwata by the indigenous Bagobo people.Script error: No such module "Unsubst".
The erect inflorescence bears 8–12 flowers[3] with broad, flat sepals and petals.[4]
Taxonomy
It was first published as Esmeralda sanderiana Rchb.f. by Heinrich Gustav Reichenbach in 1882.[5][6] It was transferred to the genus Vanda R.Br. as Vanda sanderiana (Rchb.f.) Rchb.f. published by Heinrich Gustav Reichenbach in 1882.[6] It is placed in Vanda sect. Roeblingiana.[4]
Varieties
The Philippine Orchid Society, which incorporates an image of the flower in its logo, states that the species has three varieties:[7]
Vanda sanderiana var. albata Reichb. f. in Gard. Chron. ser. 3.2 (1887) 9. Esmeralda sanderiana var. albata Will
Vanda sanderiana var. froebeliana Cogn. in Dict. Icon. des. Orch.Vanda t. 12 a (1903)
This variety has bright rose flower stalks and has very large flowers compared to the species. The lateral sepals are bright yellow, with rose coloration towards the margins and densely covered with large purple reticulated veins. The dorsal sepal and petals are rose-colored on the upper half, while the lower half has brownish-purple spots.
Vanda sanderiana var. labello-viridi Linden & Rodigas in Lindenia 1:85, t (1885) 40. Esmeralda sanderiana var. labello-viridi Will
This variety is similar to the species, with the exception that the lip or labellum is green with crimson stripes.
Distribution
Vanda sanderiana is endemic to Mindanao in the provinces of Davao, Cotabato, and Zamboanga where it is found on the trunks of dipterocarp trees at elevations below 500 meters. Over-collected, the plant is considered rare in nature. It is often used in hybridization.[8]
Use
Symbolism
In 2004, a motion was filed in the House of Representatives of the Philippines to declare the waling-waling as the country's national flower, replacing the sampaguita.[9][10] In 2013, a bill was passed by the Philippine Senate declaring the waling-waling as a national flower alongside the sampaguita.[11] However, the House Bill 5655 was vetoed by President Benigno Aquino III citing that other means were available to promote the protection and preservation of the orchid without declaring it a second national flower.[12]
