H. pallens is similar in appearance to Hypericum ternatum, but it is less woody and more procumbent. Additionally, the range of H. pallens is to the east of H. ternatum, and their ranges do not overlap. In addition, the inflorescence of the species is also similar to the inflorescence of several species in the section Campylosporus, especially Hypericum revolutum.[2]
Taxonomy
H. pallens was first published as Hypericum cuneatum by Alfred Russel Wallace in the journal Nat. Hist. Aleppo in 1794. The species was later described as H. pallens by Joseph Banks and Daniel Solander.[3] A variant of the species dubbed H. pallens var. maximum has been proposed, which would consist of the members of the species with much larger and broader leaves that are found near Antioch, but the subdivision of the species has not been accepted.[4]
Distribution and habitat
The species is found in Southern Turkey in Cilicia and Amanus, Syria in Latakia, and Lebanon along the coastal plain. It is found among hard limestone rocks at elevations of 50–1700 meters.[2]
