Stipa klimesii M. Nobis

sp. nov.

Stipa klimesii M. Nobis   , sp. nov. ( Figs. 1–2 View FIGURE 1 View FIGURE 2 )

= Stipa basiplumosa var. longearistata Munro ex Hooker   f. (1896: 229). Type:— Tibet Occ., Thomson s.n. (holotype K!).

Type:— INDIA. NW India, Jammu and Kashmir State, Ladakh, Indus Vy : Zhung (Leh), Ganglas – upper part, springs with drinking water, 3880–4000 m a.s.l., 30 July 2001, 34°12.3’N / 77°36.8’E, L GoogleMaps   . Klimeš 1155, 1156 (holotype KRA!, isotype PRA!)   GoogleMaps   .

The new species is similar to Stipa roborowskyi   , but differs by its longer anthecium [(7–)8.3–9.5(–10.5) vs. (6–)6.5– 7.5(–7.7) mm], longer ligules of vegetative shoots [(2–)3.5–7.5(–9) vs. 0.5–1.5(–2) mm], longer hairs on seta [(1–)1.3–2(–2.3) vs. (0.3–)0.5–1.1(–1.4) mm], and shorter awn [(25–)35–45(–52) vs. (40–)47–60(–68) mm]. Stipa klimesii   is also similar to S. purpurea   , but differs by longer ligules of vegetative shoots [(2–)3.5–7.5(–9) vs. (0.5–) 1–3 mm], shorter awn [(25–)35–45(–52) vs. (55–)65–90(–120) mm], slightly shorter hairs on seta [(1–)1.3–2(–2.4) vs. 2–3 mm] and by the character of the panicle, which is compressed with straight branches in S. klimesii   vs. lax with flexuous branches in S. purpurea   .

Perennial plant, densely tufted, with a few culms and numerous vegetative shoots; culms 15–48 cm tall, with 1(–2) node in the lower part of culm. Leaves of vegetative shoots: sheaths glabrous or shortly pilose with white edge, glabrous at margins; ligules membranous, (2–)3.5–7.5(–9) mm long, acute or obtuse, the apex with very short cilia, and shortly setulose on the back; blades convolute, green to pale green, 10–20 cm long, 0.20–0.45 mm in diameter, adaxial surface covered by up to 0.15 mm long hairs, abaxial surface glabrous to slightly scabrous. Cauline leaves: sheaths glabrous or shortly pilose, the margins white and glabrous, upper sheath of culms uninflated; ligules (1.5–)2.5–8(–9) mm long, acute or obtuse, at the apex with very short cilia, and shortly setulose on the back; blades convolute, green or pale green, up to 10 cm long, adaxial surface shortly pilose and abaxial surface slightly scabrous. Panicle (5–) 8–20 cm long, contracted, with (5–)10–20 spikelets, exserted, branches erect, setulose, single or paired, the lower ones up to 50 mm long. Glumes subequal, pale green to purple, lower glume (12.5–)14–16(–18) mm long, upper glume (11.5–)13–15.5(–17.5) mm long, lanceolate, tapering into a long hyaline apex, glabrous or setulose at dorsal line. Anthecium (7–)8.3–9.5(–10.5) mm long, 0.6–0.8 mm wide. Callus 1.4–2 mm long, densely and long-pilose, hairs 0.6–1 mm long; base of callus dorsally flattened and long protruding, peripheral ring 0.15–0.20 mm in diameter, scar narrowly elliptic. Lemma pale green to purple, on dorsal surface completely covered by abundant hooks and ascending hairs 0.5–0.7 mm long, apex with abundant or scattered hairs 0.5–1.0(–1.3) mm long. Awn (25–)35–45(–52) mm long, bigeniculate; column (4–)5–10(–12) mm long, twisted, 0.2(–0.3) mm wide, green or straw-coloured, pilose, hairs (1.3–)1.5–2(–2.4) mm long, gradually decreasing in length towards geniculation; middle segment of awn 5–8 mm long, pilose, hairs (1–) 1.4–2 mm long, gradually decreasing in length towards geniculation; seta slightly arcuate or straight, (15–)20–30(–38) mm long, hairs in lower part of seta (1–)1.3–2(–2.3) mm long, gradually decreasing in length towards apex. Palea equal to lemma in length, with a dorsal line of hairs. Anthers yellow or purple, glabrous, 3.8–5.7 mm long. Lodicules 3. Ovary with 2 styles. Caryopsis 5–7 mm long.

Distribution and ecology:― Stipa klimesii   is known only from Jammu and Kashmir State in northern India (Western Himalayas). It is probable that the species may be found in the neighbouring areas of Tibet, where similar habits occur. The species grows in high mountain steppes and alpine mats, between 4200 and 5100 m a.s.l.

Etymology:―The name of the species honors the collector Dr. Leoš Klimeš, the eminent Czech botanist and researcher of the flora and vegetation of Ladakh (NW India), who went missing on expedition in 2007.

Note: ―Based on the detailed description of Stipa basiplumosa var. longearistata   prepared by Freitag (1985), and examination of the holotype (holotype in K!, digital image), this taxon is conspecific with S. klimesii   [not with S. roborowskyi   as it was treated by Cope (1982), Freitag (1985) and Tzvelev (1968)] and should be regarded as its synonym. The new taxon could not be named S. longearistata   , because this is the name of an Australian species, S. longearistata Steudel (1854: 127)   .

Morphological variation:―Based on variation in the pubescence of sheaths of culm leaves, two varieties of Stipa klimesii   can be distinguished: var. klimesii   with glabrous sheaths of culm leaves, and var. pubescens   with shortly pubescent sheaths of culm leaves. The latter taxon is known only from the type collection.
