'''''Euanthe  sanderiana''''' is a flower of the [[Orchidaceae|orchid family]]. It is commonly called '''Waling-waling'''<ref>{{cite web | title =Euanthe  sanderiana(Waling-waling Orchid)  | url=http://zipcodezoo.com/Plants/E/Euanthe__sanderiana/ | accessdate = 2009-08-23}}</ref> in the [[Philippines]] and is also called '''Sander's Euanthe''',<ref>{{cite web | title =Euanthe sanderiana [Rchb.f] Schlechter 1914 | url=http://www.orchidspecies.com/euanthesanderiana.htm | accessdate = 2009-08-23}}</ref>  after [[Henry Frederick Conrad Sander]],<ref name="tacio">{{cite web | last=Tacio | first=Henrylito D. | title =Waling-Waling: Magnificent Yet Endangered | url=http://cache.zoominfo.com/CachedPage/?archive_id=0&page_id=1776723333&page_url=%2f%2fwww.bansalan.com%2fhenry%2fwaling-waling.htm&page_last_updated=4%2f1%2f2009+9%3a00%3a44+AM&firstName=Domingo&lastName=Madulid | accessdate = 2009-08-26}}</ref> a noted [[orchidologist]]. The orchid is considered to be the "Queen of Philippine flowers" and is worshiped as a ''[[diwata]]'' by the native Bagobo people.<ref name="tacio"/>

[[Heinrich Gustav Reichenbach]] originally named ''Euanthe sanderiana'' as ''[[Vanda]] sanderiana''. 

It has two forms, pink and white, also referred to as [[White|''alba'']]. M. Roebelin discovered the original pink variety in the Philippines in 1881 or 1882. [[Rudolf Schlechter]] separated ''Euanthe'' from ''Vanda'' in 1914 due to structural differences in the flowers.<ref>{{cite web | title =Plant of the Week 01/07/2002 Euanthe Sanderiana alba Schlechter  | url=http://www.killerplants.com/plant-of-the-week/20020107.asp | accessdate = 2009-08-23}}</ref> For breeding purposes and registration by the [[Royal Horticultural Society]], however, it is still treated as a Vanda.<ref>{{cite web | title =Vanda Sanderiana at Fender's Flora Orchids  | url=http://www.fendersflora.com/Vanda/sanderianagood.asp | accessdate = 2009-08-23}}</ref>

''Euanthe 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.<ref name="ESC"/> It is often used in [[Hybrid (biology)|hybridization]].<ref>{{cite web | title =Vanda sanderiana (plant) | url=http://www.britannica.com/EBchecked/topic/622886/Vanda-sanderiana | accessdate = 2009-08-23}}</ref>

Studies have shown that when raised at high [[altitude]], the plant bears flowers early.<ref>{{cite web | last =Ramasasa | first =Cris | title =Waling-Waling Orchids Bears Flowers Early When Raised At High Altitude: Says Study | url=http://www.articlesbase.com/gardening-articles/walingwaling-orchids-bears-flowers-early-when-raised-at-high-altitude-says-study-924466.html | accessdate = 2008-03-19}}</ref>

:Described by [[Heinrich Gustav Reichenbach]] in [[The Gardeners' Chronicle]] in 1887, the plant's flower  size is  smaller than that of the species. Its lateral [[sepal]]s are yellowish-green with white margins. Its dorsal sepal and [[petal]]s are white with purple spots at the base. The [[labellum]]  has purple dots. This plant was reported from [[Davao del Sur]] and [[South Cotabato]] on Mindanao Island where it grows as an [[epiphyte]] at elevations to 500 meters. This variety is now extremely rare in its natural habitat.
