The discovery of H. chimantensis on Chimanta and its characteristics came as quite a surprise, as they clearly indicate that it is much more closely related to the southern H. tatei, than to any of the northern species known to be growing in the Gran Sabana. The flowers of all other species known from the Gran Sabana have 10-15 anthers, while Heliamphora tatei var. tatei and H. tatei var. neblinae from the Amazon, and Heliamphora chimantensis have about 20; however, while the anthers of H. tatei and H. tatei var. neblinae are 7-9 mm long, those of H. chimantensis just reach 5 mm in length.
