Intermediate Bladderwort
Utricularia intermedia agg.
Lus borraigh gaelach
Family: Lentibulariaceae

Flowering August-September. Insectivorous aquatic perennial. Native.

Pale-yellow flowers with long, pointed spur, but the flowers are very rarely produced. Both floating and submerged stems are present, the leaves with toothed segments and bristle points on tips. Small, transluscent bladders that trap and digest small aquatic insects occur on separate branches, often buried in mud. Over-wintering buds.

Mainly found in the north-west and west of Ireland in shallow peaty water and on bare wet, acidic peat.
