Assessment rationale/justification
There is limited information regarding Chesneya parviflora and its distribution within the UAE. Although this species has been recorded from the southern edge of the Ru'us al-Jibal and the Dibba zone, detailed distribution data is lacking. Furthermore, the threats to this species are currently unknown and there is more to learn about its habitat and ecology. Therefore, this species is currently assessed as Data Deficient.

Taxon distribution as listed in assessment
Within the UAE, this species has been recorded from a single locality at low altitude in the southeast of the Ru'us al-Jibal (Feulner 2011). There are reportedly other scattered specimens within the adjacent Dibba zone, although the plant does not seem to generally occur in the Hajar Mountains (Feulner 2011). Present in northern Oman at c. 2,500 m (Ghazanfar pers. comm. 2019). Globally, this species occurs from Pakistan to Iran (Board of Trustees, RBG Kew 2019). Plants of the World Online does not list the UAE as a native country of occurrence for this species, but its occurrence in the Hajar Mountains is consistent with an Oman-Makran distribution, characteristic of many other species of regional plants and animals.

Habitat details as listed in assessment
The original records of this species by A.S. Gardner were from natural sites within the zone of mixed sedimentary rocks southeast of Dibba. It was subsequently recorded growing in silt at the base of a cliff, adjacent to cultivation (Feulner 2011). It is described as a perennial species (Board of Trustees, RBG Kew 2019).
