Inflorescences sciadioidal, convex, of 5–15 flowers, with peduncles extra-axillary, positively geotropic, unbranched, one at each node, producing flowers subsequently a few times, terete, 10–15 × 1.5–2.5 mm, green, sparsely pubescent when very young. Flowers with terete pedicels 2.5–3 cm × 0.06–0.08 mm, pale green, glabrous. Calyx lobes triangular, apex round, 1.5–2 × 0.5–0.6 mm, sparsely pubescent outside or glabrous, inside glabrous, ciliate; basal colleters 0.15–0.25 × 0.15–0.2 mm, one at each calyx sinus, ovoid. Buds globose, 5-ridged, dark brown or deep purple when young, turning green. Corolla shallowly campanulate, 20–23 mm in diameter; tube 9–11 mm long, creamy white, glabrous outside, pilose inside, basally densely pubescent; lobes 2–3 × 11–12 mm, very broadly triangular, valvate in bud, creamy white, glabrous outside, very sparsely pubescent inside, tip glabrous. Corona staminal 4–5 mm high, 10–12 mm in diameter, stiff and waxy-looking, white; lobes 4.5–5 × 2.3–2.5 mm, spreading, ovate, attached at the back of the anthers, inner process apiculate, not touching in the middle, outer process acute with a rounded tip, lobes with revolute margin underneath. Anthers ca 0.7 × 0.5 mm, ovate, with apical round membranaceous appendage covering the style-head apex. Pollinia 550–650 × 220–270 μm, oblong, with a round base and an obliquely truncated apex; pellucid margin present all along the outer edge; caudicles ca 280 × 180 μm, broadly triangular, almost transparent; corpusculum 300–350 × 100–120 μm, oblong; style-head 5-angled in cross section, with five spreading lobes alternating with the stamens, style-head depressed with a central raised conical apex ca 0.5 × 0.5 mm broad at the base, apex rounded; ovary 1.4–1.6 mm high, 0.3–0.4 mm in diameter, narrowly conical, apex acute. Fruit and seed not observed. Distribution and habitat Hoya danumensis subsp. amarii subsp. nov. is only known from the type locality in northern Sumatra, Indonesia, ca 900 m a.s.l. Conservation status Known only from a single collection and lacking information on the distribution area, the population size and the possible threats to the habitat, H. danumensis subsp. amarii is considered as Data Deficient (DD) (IUCN 2012). Notes Hoya danumensis subsp. amarii subsp. nov. can be separated from H. danumensis Rodda & Nyhuus (2009) subsp. danumensis because of the shape and size of the corolla that is shallowly campanulate, 20–23 mm in diameter and deeply campanulate, vs 25–35 mm in the latter; in the shape and size of the corona lobes that are ovate-oblong and 5.5–6 × 2.4–2.6 mm in H. danumensis subsp. danumensis vs ovate and 4.5–5 × 2.3–2.5 mm in the new subspecies.Published as part of Rahayu, Sri & Rodda, Michele, 2019, Hoya of Sumatra, an updated checklist, three new species, and a new subspecies, pp. 1-23 in European Journal of Taxonomy 508 on pages 4-7, DOI: 10.5852/ejt.2019.508, http://zenodo.org/record/261287

Flower buds globular, white. Flowers weakly sweetly scented (lasting about one week in cultivation), from the base of the corolla lobes to the inner apex of the corona 7–10 mm long, corolla 9–12 mm in diam. Sepals (Fig. 1d) ovate, ca. 2.5 × 1.0 mm, apex round, alternating with single glands, glabrous, a few long hairs at the junction between the sepals and the pedicel. Corolla revolute, white; lobes lanceolate, 9–11 mm long, acute at apex; free portion of lobes 7–8 × 4.5–5.5 mm, distance between each sinus 3.5–4.0 mm, abaxially glabrous, hirsute adaxially, hairs up to 0.3 mm long, lobe apex (ca. 1 mm long) glabrous, margins ciliate. Corona staminal (Fig. 1a,b,c) fleshy, dull white to light yellow, laterally spreading, ca. 3 mm high, 6.5–7.5 mm in diameter; corona lobes held at 30–40 degrees to the filament tube, outer process rounded to obtuse, flattened, only partially folded beneath (Fig. 1c), inner process acute, held at about the same height as the anther appendages. Distance between center and outer corona process 3.3–3.6 mm; distance from center to corona sinus 1.5–1.8 mm; beneath corona, distance between filament tube and anther skirt (beneath guide rail) 0.6–0.8 mm. Pollinaria erect, ca. 830 × 430 µm; pollinia elongated, compressed, 660 × 220 µm, with a lateral pellucid margin; retinaculum 260 × 160 µm; translator 70–100 µm long. Ovary lanceolate, about 1.7 mm long, light green. Fruits and seeds not seen. All measurements from fresh type material.</p> <p> <b>Phenology:</b> — <i>Hoya rotundiflora</i> is commonly seen flowering in cultivation during the summer months, which is consistent with the flowering periods of plants from a monsoonal area such as south Myanmar. A similar flowering season has been observed for <i>Hoya pandurata</i> Tsiang (1939: 125) and <i>H. chinghungensis</i> (Tsiang & P.T.Li) Gilbert <i>et al.</i> (1995: 9) both originating from this geographical area (personal observations).</p> <p> <b>Habitat and distribution:</b> —Little is known about the original habitat of this species. It has been observed to be difficult to grow and flower in constantly warm areas such as Bangkok (S. Somadee, personal communication) and therefore it is likely to inhabit higher elevated areas where winter temperatures are lower and where there is a greater disparity between day and night temperatures.</p> <p>The type plant can be traced back to a market in Sangklaburi in Kanchanaburi province, Thailand, where it was first found in 2005. The plant was collected near the border in neighboring Myanmar but the exact locality has been kept secret by the seller.</p> <p> <b>IUCN Red List category:</b> —Population size and distribution range of <i>Hoya rotundiflora</i> cannot be estimated, as it is so far known from only a single collection. Due to the high horticultural interest in <i>Hoya</i> it is surprising that no further collections belonging to this taxon have been made since its first introduction into cultivation in 2007. This may suggest that the species may have a very restricted distribution range and small population size containing a limited number of mature individuals or its habitat may be inaccessible, for example being on steep karst formations. Further, <i>Hoya</i> populations are often under pressure because of frequent collection to supply the horticultural trade and therefore <i>H. rotundiflora</i> is hereby suggested as vulnerable according to IUCN Red List criteria (IUCN 2001).</p> <p> <b>Additional specimen examined:</b> — <i>Ex Hort.</i>, 15 June 2010, <i>Rodda Hort 2010/1</i> (L, SING, TO).</p>Published as part of <i>Rodda, Michele & Simonsson, Nadhanielle, 2011, Hoya rotundiflora (Apocynaceae, Asclepiadoideae), a new horticulturally important species from Myanmar, pp. 37-43 in Phytotaxa 27</i> on pages 37-41, DOI: 10.11646/phytotaxa.27.1.4, <a href="http://zenodo.org/record/4894182">http://zenodo.org/record/4894182</a>

Inflorescences 3.5–4 cm in diameter, of 20–25 flowers, sciadioidal, convex; peduncles 15–30 × ca 3 mm, terete, extraaxillary, laterally held, one at each node, producing flowers over an extended period of time, brownish, sparsely pubescent. Flowers with terete pedicels 13–17 × 0.7–1 mm, pale brownish yellow, minutely papillose. Calyx lobes ovate or round, apex rounded, 1–1.5 × 0.8–1 mm, minutely papillose outside, glabrous inside, ciliate; basal colleters 250–300 × 120–150 µm, ovoid, one at each calyx sinus.

Corona staminal, 1.2–1.4 mm high, 3.7–4.2 mm in diameter, white; lobes 2–2.3 × 1.1–1.2 mm, attached at the back of the anthers, held at a ca 80º angle, ovoid, slightly carinate above, inner process acute, erect, outer process rounded, spreading, with a basal revolute margin. Anthers ca 0.7 × 0.6 mm, ovate, including a thin apical round membranaceous appendage. Pollinia 350–400 × 130–150 μm, oblong, with a round base and an obliquely truncate apex; with a pellucid margin along the outer edge; caudicles ca 40 × 20 μm, much reduced; corpusculum 120–140 × ca 50 μm, oblong; style-head 5-angled in cross section, with five spreading lobes alternating with the stamens, style-head apex depressed with a central conical acute tip ca 200 µm high; ovary 0.8–0.9 mm high, ca 0.35 mm in diameter at the base, conical, lightly curved, apex acute. Fruit and seed not observed. Distribution and habitat Hoya rigidifolia sp. nov. is only known from the type locality in the lowland forest of Pulau Siberut, southern Sumatra, Indonesia. Conservation status Known only from a single collection and lacking information on the distribution area, the population size and the possible threats to the habitat, H. rigidifolia sp. nov. is considered as Data Deficient (DD) (IUCN 2012). Notes Hoya rigidifolia sp. nov. flowers only open for a single day. The flowers of H. finlaysonii are also open for a single day and have a similar flower morphology (rotate corolla, ovoid corona lobes of similar size). Both species are, however, easily separated based on leaf characters. Hoya finlaysonii has lanceolate to oblong leaves with pinnate venation, usually darker than the rest of the lamina; H. rigidifolia sp. nov. also has pinnate venation, but additionally it has two basal secondary veins running along the entire length of the lamina. The leaf venation of H. erythrina Rintz (1978) is similar to that of H. rigidifolia sp. nov.; however, both species can be separated based on flower charaters: H. erythrina has flowers with corolla> 15 mm in diameter when flattened, long-pubescent inside, and lasting> 2 days, while H. rigidifolia sp. nov. has flowers with corolla <12 mm in diameter when flattened, glabrous inside, and lasting one day.Published as part of Rahayu, Sri & Rodda, Michele, 2019, Hoya of Sumatra, an updated checklist, three new species, and a new subspecies, pp. 1-23 in European Journal of Taxonomy 508 on pages 12-13, DOI: 10.5852/ejt.2019.508, http://zenodo.org/record/261287

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
