Ichthyothere pastazensis is a species of flowering plant belonging to the family Asteraceae (the sunflower or daisy family). It is primarily found in South America, specifically in the tropical regions of Ecuador.
Taxonomy and Discovery The species was formally described in 1987 by the American botanist Harold Robinson in the scientific journal Phytologia. It is classified under the genus Ichthyothere, which is situated within the tribe Heliantheae. The specific epithet pastazensis refers to the Pastaza Province in Ecuador, the geographic area from which the type specimen was collected.
Characteristics and Distribution As a member of the genus Ichthyothere, the species is a perennial herb or subshrub. Plants in this genus typically exhibit opposite leaves and small, white or yellowish flower heads (capitula) arranged in clusters. Ichthyothere pastazensis is native to the moist lowland forests of the Ecuadorian Amazon. Detailed morphological descriptions beyond those in specialized taxonomic literature are limited, and its specific conservation status has not been widely evaluated by the IUCN.
Etymology and Cultural Context The genus name Ichthyothere is derived from the Greek words ichthys (fish) and thera (hunt). This name refers to the traditional use of several species within the genus by indigenous peoples in the Amazon basin as ichthyotoxins. These plants often contain chemical compounds, such as ichthyothereol, which can stun fish when placed in water, making them easier to harvest. While the genus is well-known for these properties, specific ethnobotanical applications or chemical analyses for Ichthyothere pastazensis in particular are not extensively documented. Accurate information regarding its specific chemical composition compared to other members of the genus is not confirmed.
