Utricularia grandiflora

Utricularia grandiflora is not a current name. Persoon's U. grandiflora (1805) is a superfluous name for U. alpina, and Martens's later homonym (1841) is a synonym of the North American aquatic U. macrorhiza. This profile follows U. alpina, a large-flowered, tuber-forming bladderwort of wet montane forest in the Lesser Antilles and northern South America that grows on the ground or as an epiphyte.

Where it grows wild

As U. alpina, it grows in moss on trunks and in wet humus in cloud and montane forest on the volcanic islands of the Lesser Antilles and in the northern Andes and tepuis.

No records under this name. U. alpina's localities suggest mainly mid-elevation wet montane forest, roughly 500–1500 m.
