A Conversation Beyond Matter: Carolyn Kirschner
No full text“Artist and researcher Carolyn Kirschner will present her project ‘Iconoclash Slow Squeeze’ created during the Beyond Matter Residency program and answer related questions about, among others, the relationship between materiality, representation and physical stimulation in conversation with Dr. Cecilia Preiss, research associate at the ZKM Hertz-Lab.
With ‘Iconoclash Slow Squeeze’, the artist explores so-called Autonomous Sensory Meridian Responses, or ASMR for short – tinglingly pleasant reactions that can be triggered by auditory and visual stimuli that place the body into a state of deep relaxation. Incorporating well-known modernist artworks, recontextualizing them and simultaneously transferring them into a different material form, Kirschner questions the connection between art, fetish, pleasure and experience.
Immediately following, the world premiere of her audiovisual work will take place at the ZKM's Cube.
The Beyond Matter Residency was a fellowship program that took place within the framework of the international practice-based research and development project Beyond Matter, funding artists and theorists researching virtual worlds and their technical and theoretical implications between 2020 and 2022.
Beyond Matter is funded by the European Commission and the German Federal Commissioner for Culture and the Media.”

It grows in a mosaic of gravelly patches, substeppe grasslands with low vegetation coverage and subruderal places. Specimens examined:—[RUSSIA, Respublica Altay] SW.

No full text23. Taraxacum angarense Kirschner & Štěpánek, sp. nov. Type:—[RUSSIA] Sibiria merid., urbs Irkutsk, graminosis in urbis centro, prope ecclesiam haud procul a deversorio Angara [Irkutsk, grasslands in the city centre, near the church, in the vicinity of the Angara Hotel], 25 Oct 1985, J. Kirschner & J. Štěpánek, cultivated as JŠ 2692 (PRA, no. det. 35981, holotype; isotype: PRA, no. det. 36704). Etymology:—The name is derived from the fact that this species occurs at three mutually remote localities situated along River Angara. Exsiccates:— Taraxaca Exs., no. 1369–1371. Diagnosis:—Plantae inter sectionum Dissectorum et Borealiorum intermediae, foliis profunde pinnatisectis, lobis lateralibus foliorum remotis patentibus angustis, phyllariis involucralibus exterioribus erectis usque patentibus, anguste lanceolatis vel lanceolatis, marginibus pallidis, luto-viridibus, 0.5–0.6 mm latis, apice atrocornutis, cornibus brevibus obtusis, acheniis pallide stramineobrunneis, corpore in pyramidem subcylindricam subabrupte transeunte bene dignoscendae. Plants small to almost medium-sized, usually to 9–13 cm tall. Petiole narrow, unwinged, or narrowly winged in outer leaves, purple (rarely green), arachnoid; plant base with sparse yellowish hairs, tunic only slightly developed. Leaves deep green, sometimes dark green, sparsely arachnoid, mainly along the mid-vein, with interlobes bordered or blotched dark brown-purple, oblanceolate in outline, usually 6–11 × 1.5–3.5 cm, deeply pinnatisect, with lateral segments in (3) 4 (5) pairs, patent to ± forward-pointing, usually with broad base, on the distal margin abruptly narrowed in a linear to linear-lingulate distal part, entire or with 1–2 lobules or teeth on the broad basal part, concave, proximal margin straight to convex, entire or with a single subbasal tooth; terminal segment tripartite, with a linear-triangular distal part and patent to forward-pointing basal lobules, ± entire; interlobes often bordered or even blotched dark brown-purple, 2–3 mm wide, entire or sparsely lobulate and/or dentate; mid-vein usually purplish, sometimes pale green. Scapes brownish green, arachnoid, ± equalling leaves. Capitulum yellow or lighter yellow, 3–4 cm wide. Involucre dark green, 9–10 mm wide and rounded at base. Outer phyllaries quite numerous, usually 14–17, erect, erect-patent or almost patent, almost not imbricate, narrowly to broadly lanceolate, usually (5–) 6–7.5 (–8.5) × 1.8–2.6 mm, usually dark green to blackish green, marginal and distal parts usually suffused purplish, border sharply delimited, narrow, 0.1–0.2 (–0.3) mm wide, rarely, in the basal part of phyllaries, a yellow-green border to 0.5–0.6 mm wide, margin ± glabrous, apex almost blackish, usually suffused purple, with a black horn to ca. 0.5 mm high; inner phyllaries usually 14–15 mm long, flat to corniculate. Outer ligules flat, striped light grey-purple outside, inner ligule teeth faintly greyish-purplish. Stigmas darker discoloured, yellow-green, with dark pubescence outside. Pollen present, pollen grains irregular in size. Achenes light greyish stramineous-brown, 3.7–4.4 × 0.8–0.9 mm, body subsparsely but distinctly spinulose and squamulose (spinules erect-patent), subabruptly narrowing into a subcylindrical cone (0.7–) 0.8–1.0 (–1.1) mm, ca. 0.3 mm thick at base, 0.2–0.25 mm distally, often with 1–2 spinules on the proximal 1/3 of the cone; beak 9–10 mm, pappus 6–6.5 mm, white to yellowish white. – Agamosperm. – Fig. 26. Diagnostic notes:—The relatively narrow, lanceolate, dark and horned outer phyllaries may point to T. sect. Borealia but the horns are relatively short, obtuse, the cone is subcylindrical, and the leaves have a characteristic shape of T. sect. Dissecta. The character combination places this species in an intermediate position between the above two sections, closer to the latter. Distribution and habitat:—At several sites between Lake Baikal and Bratsk on the Angara River, Siberia. Gravelly and sandy shore habitats and dry grasslands on adjacent slopes, between 400 and 500 m a.s.l. Specimens examined:—[RUSSIA, Irkutskaya oblast] S.

Taraxacum pseudohoppeanum Kirschner & Stepanek 1985
No full text1. Taraxacum pseudohoppeanum Kirschner & Štěpánek (1985: 122). Type:— FRANCE. Alpes Maritimae, Prov. di Cuneo, Pian Tendasco, supra Val Casterino di Tenda, in pratis alpinis, solo calcareo, 2000 m, 21 Jun 1911, C. Bicknell & L. Pollini [Fiori et Béguinot, Fl. Ital. Exs., ser. II., no. 1995] (K, no. det. 2379, holotype). Note: — A part of the herbarium material cited by van Soest (1976) under the name of T. caespitosum van Soest (1976: 173), and by van Soest (1969) as T. plumbeum, belongs to T. pseudohoppeanum. See also the list of specimens examined. Description:— Kirschner & Štěpánek (1985:122–123). Illustrations:— Kirschner & Štěpánek (1985: 121 and Plate X). Exsiccates:—Fiori et Béguinot, Fl. Ital. Exs., ser. II., no. 1995; Taraxaca Exs., no. 199. Diagnostic notes:— Taraxacum pseudohoppeanum belongs to the group characterized by broadly ovate to ovate outer phyllaries with pale greenish proximal part of phyllaries, and by red-brown achenes. From the most closely related species, T. janchenii, it can be distinguished by its greenish stigmas, patent, subacute leaf lateral segments and the absence of the dominant, broadly obtuse terminal segment of leaves (Fig. 1). Taraxacum pseudohoppeanum is tetraploid, with 2n=32 (Krahulcová 1993). Note:—Contrary to the sectional conception in Kirschner & Štěpánek (1985), T. pseudohoppeanum represents the only member of T. sect. Erythrocarpa in the western part of the Alps. In the meantime, we modified and extended the circumscription of T. sect. Obliqua to include a group of taxa derived from the Pyrenean sexual populations of T. pyrenaicum (= T. andorriense Sahlin (1984: 113)), and the latter section therefore, in all likelihood, includes also T. aquilonare Hand. -Mazz. (see also the description and illustrations of T. aquilonare in Kirschner & Štěpánek (1985: 118–121)). Distribution and ecology:— Taraxacum pseudohoppeanum is confined to subalpine and alpine limestone rock crevices, gravel and stony meadows at (1000–) 1800–2200 (–2320) m in the Maritime Alps, Wallis, Piemont and South Tirol, i.e. in France (with the highest number of localities), Italy and Switzerland (Fig. 2).
