Utricularia cornigera
Utricularia cornigera is a large perennial bladderwort from the summit of Pedra do Sino (about 2,100 m) in the Serra dos Órgãos, Rio de Janeiro, Brazil. It was split from U. reniformis by Studnička in 2009, after being grown for years as U. reniformis 'Big Sister'. It has larger kidney-shaped leaves than U. reniformis and two distinct types of bladder trap. It is a cool-growing, high-altitude plant: it needs bright light, constantly moist ground and cool nights, and warm conditions or tropical lowland care will make it fail.
Where it grows wild
All known collections are from Pedra do Sino at about 2,100 m, in the park's high-altitude zone of open grassland and shrub (campos de altitude) above the cloud forest. Its close relatives grow in wet moss, boggy soil and seepage among grasses, and this species probably does the same. Detailed microhabitat notes were not found.
Known collections are from about 2,100 m on Pedra do Sino, the highest peak in the Serra dos Órgãos at 2,263 m.
