Hypericum minutum P.H.Davis & Poulter
|
Hypericum minutum is a species of flowering plant in the St John's wort family Hypericaceae. It is a small perennial herb that grows in tufts. It has slender and brittle stems, flowers in clusters of one to three, yellow petals with black and amber glands, few stamens, and a seed capsule with narrow grooves. H. minutum is closely related to H. huber-morathii and H. sechmenii and resembles a smaller form of the latter plant. The plant is endemic to Turkey, and is found among limestone rocks in a limited region of southwestern Anatolia. Originally excluded from a comprehensive monograph of Hypericum, the species' placement within the genus is unclear. It has been placed in both section Adenosepalum and section Origanifolium.
Etymology

Description
Hypericum minutum is a small
The flowers are usually clustered in groups of one to three. The
Hypericum minutum can be told apart from its closest relatives, H. sechmenii and H. huber-morathii, by several characteristics. These include its shorter stems, fewer flowers per cluster, bracts with tooth-like edges, many amber glands on the petals, and later flowering time in July.[9] In general, it resembles a smaller form of H. sechmenii.[7]
Taxonomy
The species was first
- Hypericum subg. Hypericum
- Hypericum sect. Adenosepalum
- Huber-Morathii Group
- H. decaisneanum - H. formosissimum - H. huber-morathii - H. minutum - H. sechmenii
- Huber-Morathii Group
- Hypericum sect. Adenosepalum
The name was accepted again in 2010 in a cladistic analysis of the genus, and in a review of the taxonomy of Hypericum by Robson and Sara Crockett in 2011, though no clarification was given as to its classification within the genus in either report.[11][12]
Distribution, habitat, and ecology
Hypericum minutum is one of eight species of Hypericum sect. Adenosepalum that are native to Turkey.[14] Its holotype was collected outside the village of Bozdağ in the direction of Acıpayam, in the coastal Aegean region of Anatolia.[15] The species is rare, and can be found in the crevices of limestone rocks at altitudes of 1,800–2,000 meters,[15] where it grows alongside Globularia dumulosa,[15] a small shrub that is also endemic to southwestern Anatolia.[16]
Hypericum minutum was listed as a rare species globally and in Turkey by the 1997 IUCN Red List.[17] A 2011 review of Turkish Hypericum species reported it as endemic to the country, and labelled it as an endangered species according to the IUCN's rating system.[1]
