Description
Shrub 0.08-0.2 m tall, erect, bushy, rounded, with branches tortuous. Stems 2-lined when young, soon terete; bark greyish brown to whitish grey. Leaves sessile or with pseudopetiole up to c. 0.7 mm; lamina 6-15 x 3.5-9 mm, elliptic or oblong-elliptic to obovate, somewhat paler but not or scarcely glaucous beneath, midrib and reticulate venation prominent on both sides, chartaceous, deciduous during second year; apex obtuse or subapiculate to rounded, base cuneate to angustate or shortly pseudopetiolate; venation: 3-6 pairs of major and minor laterals, distinct from tertiary reticulation. Inflorescence l-3(-9)-flowered, from 1-2 nodes, rounded-corymbiform when several-flowered; pedicels 4-7 mm; bracteoles triangular-subulate, margin entire. Flowers c. 15-18 mm in diam.; buds ellipsoid, rounded. Sepals 2-4 x 1.3-1.7 mm, unequal, shortly united, oblong to ovate, subacute to rounded, margin entire, glands submarginal, veins 3-5, not prominent. Petals bright? yellow, 10-12 x 4-5 mm, 3-4 x sepals, oblong-lanceolate, unequally retuse; laminar glands linear to punctiform. Stamens c. 20, longest c. 11-12 mm, about equalling petals. Ovary c. 2.5 x 1.5mm, narrowly ovoid-ellipsoid; styles 8-9 mm long, c. 3-4 x ovary, narrowly curved-ascending; stigmas narrow. Capsule (immature) ovoid. Seeds not seen.[2]
H. vacciniifolium is closely related to the Libano-Syrian H. nanum, differing essentially from it in the thinner leaves with prominent venation and angustate to pseudopetiolate base and the smaller number of stamens, and usually in the fewer (often only 1) -flowered inflorescence and relatively broader, less acute sepals.[2]
Distribution
H. vacciniifolium is found only in the East Cilicia region of Southern Turkey. The species appears to be confined to a small area of the Taurus Mountains. It can be found on limestone cliffs at altitudes of 1000-1500 meters.[2]

Uses
H. vacciniifolium, along with other Turkish species of Hypericum, is used in local folk medicine. It is specifically used to help treat eczema, swelling, bruises, and minor wounds. In lab conditions, the species has been proven to have antibacterial properties against Staphylococcus aureus.[4]

gollark: I prefer the set dictionaries.
gollark: ``` A language based on the idea of communism. There would be only one great editor (a wiki or similar) and all programmers would write only one big program that does everything. There would be only one datatype that fits everything, so everything belongs to one single class. Functional programming is clearly based on the idea of communism. It elevates functions (things that do the work) to first class citizens, and it is a utopian endeavor aimed at abolishing all states. It is seen as inefficient and unpopular, but always has die-hard defenders, mostly in academia. Besides, ML stands for Marxism-Leninism. Coincidence? I think not. It should be called Soviet Script and the one big program can be called the Universal Soviet Script Repository or USSR for short. And they put all the packages together in one place (Hackage). It already exists and is called 'Web'. It already exists and is called 'Emacs'. Emacs is the one great editor, and the one big program (Emacs can do almost anything). The language is Emacs Lisp, which is functional, and almost everything is a list (the one great datatype/class). Unfortunately```
gollark: It's pronounced Piephoon, by the way.
gollark: Owwww, my eyes.
gollark: I personally use LineageOS, microG and the Yalp play store thing.
