Abstract

Dianthus koreanus sp. nov., from Gyeongsangbuk-do, Republic of Korea, is described and illustrated. It is a chasmophyte

growing on the rocks on the seashore in the eastern coast of Korea. The new species is similar to D. chinensis by its vegetaꠓtive and floral morphology. Differential characters refer to the leaves (oblanceolate to oblong and greenish-gray coriaceous),

and the bracts (3 pairs, each bract being elliptic to obovate with apex acute). The conservation status of D. koreanus was

assessed according to the IUCN Red List criteria.

Key words: East Asia, Dianthus chinensis, endemic species, IUCN

Introduction

Dianthus Linnaeus (1753: 409) is one of the largest genera of Caryophyllaceae Juss. consisting of approximately 300

species of herbaceous annuals, biennials, and perennials plants, that are common in Europe, Asia and North Africa,

whereas some species occur in North America and South Africa (see e.g., Reeve 1967, Mabberley 2008, Vaezi et al.

2014). This genus is easily distinguished from the other genera beloning to Caryophyllaceae by its epicalyx scales

(bracts), tubular calyx, and peltate seeds (Bittrich 1993, Bacchetta et al. 2010, İlçim et al. 2013).

An important center of diversity for Dianthus is the central Mediterranean area (Sardinia, Corsica, Sicily, Italian

Peninsula, and Croatia) where the number of taxa is high (Conti et al. 2005, Peruzzi et al. 2015), while only 10 taxa

are recorded in NE-Asia (Charkevicz 1996, Dequan & Turland 2001, Akiyama 2006, Hong 2007).

Recent field investigations carried out in the eastern coast of Korea allowed us to discover an unusual and rather

isolated population of Dianthus, which appears to be morphologically well different from the other known taxa. After

examining the various floras and herbarium specimens of Korea and adjacent countries, we concluded that the collected

specimens could be proposed as a new species for Science, named Dianthus koreanus.

Taxonomic treatment

Dianthus koreanus D.C. Son & K. Lee, sp. nov. (Figs. 1, 2)

Type:—KOREA. Prov. Gyeongsangbuk-do, Uljin-gun, Giseong-myeon, Mangyang-ri, Giseongmangyang beach, elevation 30 m,

36.83455°N, 129.44336°E, 16 July 2015, Lee 2453 (holotype KH-1460258!, isotype KH-1460259!).

Diagnosis: Herbs perennial, 25–50 cm tall. Roots woody. Stems laxly caespitose, ascending at base, often somewhat

woody towards base, densely pubescent. Leaves sessile, coriaceous; cauline leaves opposite, oblanceolate to oblong

(2.5–4.5 × 0.5–1.5 cm), mid-vein prominent, apex acute to obtuse, base cuneate to attenuate, base amplexicaule,

margins short ciliate, both surfaces densely pubescent, greenish-gray coloured; sterile shoot leaves similar to cauline

ones, developing at flowering season. Flowers solitary or in dense cymes; pedicel 0.5–1.4 cm long; bracts 3 pairs,

elliptic to obovate, about 1/4–1/2 as long as calyx, margin membranous-ciliate, apex acute. Calyx gamosepalous,

cylindrical, 1.5–2.5 cm long, 5-toothed, with many parallel veins. Petals limb bright red, purple-red or pink-coloured,

obovate-triangular (1.3–1.5 cm long), apex irregularly toothed; throat spotted and laxly bearded. Stamens 10, exserted,

versatile; filaments long, slender; anthers blue-colored. Ovary 1-locular, on a short gynophore, with chartaceous cap;

ovules many on free central placenta; styles 2, linear, longer than ovary, pubescent. Capsule cylindrical, 2.0–2.5 cm

long, surrounded by calyx, apex 4-toothed. Seeds black, flat, orbicular
