TYPE:— PERU. Dept. Amazonas: Prov. Bongará. Río Utcubamba, 12 km below Caclic, 1420 m, 21 March 1964, P.C. Hutchison & J.K. Wright 4473 (holotype USM, isotypes F, MO, NY, UC, US). Annual herb 20–60 cm tall, densely branched from base, branches basally decumbent, 2–6 mm thick near base, sparsely covered with yellowish-brown setae 1.5–2.0 mm long and densely covered with glochidiate trichomes, decorated with dark green stripes. Leaves petiolate, lower petioles 35–55 mm long, sparsely setose, upper leaves subsessile; lamina rhomboidal to widely ovate, 40–110 mm long, 35–60 mm wide, base cuneate, truncate to rounded, margin lobed with 2–(3–7) triangular lobes on each side, lobes ca. 5–15 mm long and 5– 12 mm wide, margin coarsely serrate; abaxial surface covered with few pale setae 1.0– 1.5 mm long and very densely covered with glochidiate trichomes 0.25–0.50 mm long, adaxial surface covered with reddish brown setae 2.0– 2.5 mm long, scabrid trichomes 0.50–0.75 mm long and shorter glochidiate trichomes. Flowers in a terminal mono- or dichasia up to 35 cm long overall, with 5–8(–15) deflexed flowers per branch; bracts narrowly ovate, serrate, approximately 5–10(–23) mm long, 2–3(–10) mm wide; pedicels ca. 5–8 mm long; calyx very densely covered with glochidiate trichomes and reddish brown setae, tube conical, 3–4 × 3 mm, calyx lobes ovate-acuminate, ca. 4 mm long, ca. 1.5–2.0 mm wide; petals deeply cymbiform, 8–11 mm long, 3–4 mm deep, bicolourous, distally off-white, proximally blushed with rusty yellow (Fig. 2), base unguiculate and abruptly widened into two small, triangular teeth 2–3 mm from base, densely covered with glochidiate hairs and uniseriate gland-tipped trichomes on back; nectar scales ovate in dorsal view, narrowed above, ca. 4 mm long, ca. 3 mm wide, base incurved, back with two elliptical, confluent nectar sacs at base, these distally red, neck conspicuously thickened, slightly recurved, without filaments, laterally protracted into two small erect wings ca. 1 mm long and 0.5 mm wide; staminodia 2 per scale, ca. 5 mm long, base slightly dilated, filiform above, sparsely papillose to epapillose, white; stamens with filaments 7–9 mm long, white, anthers ca. 0.5 mm long and wide, yellowish brown. Fruit a widely cylindrical capsule with persistent calyx lobes, pedicel erect, ca. 25 mm long, capsule 8–18 mm long and ca. 8 mm wide at apex, densely covered with scabrid and glochidiate hairs 0.5–1.0 mm long, opening with three apical valves; seeds numerous, testa reticulate, black. Distribution:—The species is so far known only from the Department Amazonas, Province Chachapoyas and the bulk of the collections are from the Utcubamba valley (Fig. 1). The type collection is some 30 km northwest of the town Chachapoyas close to the small village of Caclic. A single record is known from the Marañon valley, where the species was collected on the road between Balsas and Leymebamba, some 40 km south of Chachapoyas. Although herbarium collections are scarce so far, the taxon is likely present in suitable habitats throughout the valleys of the Río Utcubamba and Río Marañón in this region. Habitat:— Nasa sanchezii is found in open, often disturbed habitats as is typical for many species of Nasa. It has been collected along new road cuttings in fairly dry scree and gravel slopes at elevations of 1400– 2200 m, where it is the only species of the genus (in this region and at this elevation). The collections made by the authors where either along roadsides, or in adjacent dry-shrub forest. The type collections provides no annotations about the habitat. Affinities:—Although morphological variation within a taxon is sometimes high in Nasa, collections of N. sanchezii are all quite homogenous with only minor differences in diagnostic characters. The taxon is well distinguished from all other species of Nasa by its small flowers with the basally rusty-yellow petals (Fig. 2) and small leaves with typically two triangular leaf lobes on each side (Fig. 3). The collection here chosen as the type collection bears the original determination “ Loasa (Nasa) chenopodiifolia Desr. ”, which is a superficially similar species from Lima and neighbouring departments (Henning & Weigend 2009), however, N. sanchezii differs from that species in its widely branched habit (versus stiffly erect habit), triangular leaf lobes (versus narrowly ovate leaf lobes), much narrower, distinctly clawed and proximally rusty-yellow petals (versus wide, uniformly white petals) and shorter fruits (Fig. 2, 3). The affinities of N. sanchezii remain unclear at present. Etymology:—The species is named in honour of Isidoro Sánchez Vega (Cajamarca, Peru), eminent scholar of the flora of northern Peru.

ICE-T is a team effort of the German Alfred-Wegener-Institute for Polar Research, the Italian Universities of Padova and Perugia, the INAF Observatory Catania, and the Catalonian IEEC in Barcelona, Spain, and the AIP with collaboration from the University of New South Wales, Australia and the University of St Andrews, U.K
Depe Insichten: Plattdeutsche Fabeln
No full textNew publication of the 1964 "Das Fabelbook." This little book is inviting, and I took the invitation. Alas, Plattdeutsch remains a step beyond me, even though there is a pair of pages at the end, just before the T of C, titled "Een Hölp för den Leser." These seem to be invented fables, and they are certainly rich in dialect!. 50 fables on 83 pages. 4¼" x 7½".Language note: PlattdeutschHans Henning Hol

Fruit an erect, cylindrical capsule with persistent calyx lobes, pedicel erect, ca. 20 mm long, capsule 14–17 mm long and ca. 5 mm wide at apex. Distribution:—The species is so far only known from two, nearby (~ 16 km) collections from the Cordillera Urubamba northeast of the Urubamba-valley in the Department Cusco, Province La Convención (Fig. 1). Habitat:—Referring to the notes made by the collectors, N. urubambensis can be found in either disturbed primary forest (remnants) or secundary woodland. This and the elevation range of 2000–3000 m is typical for species of Nasa, as described above. Affinities:—At first glance, the two collections differ dramatically in terms of leaf shape and size and overall habit. One specimen is stifly errect with small thin leaves, whereas the other collection is a branched compact plant with larger and broader leaves. An identical flower and capsule morphology and the virtually same geographical origin indicate that these morphological differences are of little systematic value and are rather a result of different microclimatic conditions at the respective locations. Plants that are exposed to full sunlight and the resulting drought in the inner-Andean valleys tend to have smaller leafs and are less branched than individuals that grow in semi-shade under moister conditions. Nasa urubambensis seems to be able to complete its lifecycle at different, even disturbed sites (landslides/rockslides, road margins, crop plantations) which is typical for Nasa species in general and the N. poissoniana group in particular. Nasa urubambensis especially resembles N. ferruginea due to its small flowers and similarities in habit and leaf morphology. But, unlike N. ferruginea its nectar scales are uniformly pale yellow and the plants are only sparsely setose. In the province of La Convención, only two other species of the group are found, namely N. raimondii and N. vargasii. Both can easily be distinguished from N. urubambensis by their bicolorous nectar scales (white or yellow resp. with red markings) and divergent leaf morphology (see: Henning & Weigend 2009), with rhombic leaves, that are irregularly shaped and shallowly lobed (N. urubambensis) vs. widely ovate (N. vargasii, N. raimondii) with either a broader, subpalmately lobed lamina (N. vargasii) or an only shallowly lobulate, regular serrate lamina (N. raimondii). The latter differs even more dramatically by its broadly amplexicaul bracts which are always petiolate in N. urubambensis (Fig. 4). Etymology:—Species delimitation in Nasa is usually based rather on a unique combination of frequently observed characters than on clear morphological autapomorphies. Since the new Nasa shows no single striking character, but can easily be distinguished from the other species found in that region, we called it ‘urubambensis’ after the Cordillera where it has been collected twice. This area of course is named after the Urubamba-river and its valley, which is the natural limit of the Cordillera in the south and east. Additional specimen examined (paratype):— PERU. Dept. Cusco.

Keeping objects live
Full text linkIt is often assumed that museum exhibits are inert but, in contrast to artifacts in most mainstream institutions, those at the Museum of Witchcraft, The Valiant Soldier community museum, and the Dartmoor Prison Museum are felt to be fully functioning and, to some extent, potent or dangerous. In order to consider why this is the case, this essay investigates how museums are considered to “kill off” their exhibits and why this process does not occur in these small, independent organizations. Notably, the three venues have few or no paid members of staff and limited opportunities for gaining state funding. Operating largely independently of the public sector, they have no need to adopt official priorities and in consequence their modes of practice differ from those encountered in major institutions. They also have close links to their immediate location and communities. Focusing on these museums therefore raises the possibility that the “death” of objects is not a necessary condition but that their demise depends upon the specific character and circumstances of display
