Bauhinia lingua
Taxonomy
Bauhinia lingua is a very polymorphous species like B. semibifida and some of its variations approach B. aherniana. We have separated two varieties based on formerly proposed species but a number of other species described are less easy to maintain. It is evident that isolated populations to some extent have become recognizable. Thus small-flowered specimens from N Luzon have been dealt with as B. pinchotiana, similar appearance is found among collections from the Moluccas. Large-flowered plants from various localities in the central Philippines have been treated as B. warburgii; other large-flowered plants from Celebes have been described as B. minahassae. A collection from Butuan City, Philippines (.PNH 98205) with almost glabrous leaves and flower buds may represent a undescribed taxon; the material, however, has no fully developed flowers.
It is possible that, when a much larger amount of material is available and extensive field studies undertaken, some of these variations could be recognized formally; but at the present moment we find it safer to avoid further splitting.
Still Bauhinia lingua is most easily distinguished on its narrow tubular hypanthium, gradually tapering towards the pedicel.
