15. Galium decaisnei Boiss., Diagn. Ser. 1. 6: 69. 1846. Fl. Or. 3: 77. 1875; Pobed. in Schischkin, Fl. URSS 23: 31. 1958.


  • Galium setaceum subsp. decaisnei (Boiss.) Ehrend.
  • Galium setaceum var. leocarpum Boiss. ex Post
  • Galium setaceum var. longipedicellatum Post

    Annual, erect herb. Stem slender, circular, young branches usually puberulous, otherwise glabrous. Leaves 6 in a whorl, 6-8 x 1-3 mm, narrowly linear, basal leaves obovate-oblanceolate, base of the upper leaves setaceous, revolute, glabrous-puberulous. Inflorescence of axillary and terminal cymes; peduncle 10-20 mm long, few-flowered; pedicel 3-6 mm long, filiform, glabrous. Flowers minute. Corolla white, lobes shortly apiculate or submuticous. Fruit subglobose, c. 1 mm in diameter, brownish, covered with short appressed white hairs, rarely glabrescent, mericarps mottled.

    Fl. Per.: Feb.-July.

    Syntypes: Hab. in Persia australis in fissusis rupium prope Gere, Kotschy 66; in regno Mascatensi, Aucher-Eloy 4660; in monte Sinai, Bove; Schimper. (GBOIS).

    Distribution: S.E. Mediterranean, extending up to Central Asia through Iran, Afghanistan and Pakistan.

    Ehrendorfer (l.c.) has treated this taxon as a subspecies of Galium setaceum Lamk. However, in view of the clear cut differences in the shape of the corolla-lobes and the type and the density of the hairs on the fruit, Galium decaisnei Boiss. and Galium setaceum Lamk. are treated as two distinct species. Ascending up to 1500m.
