Redalyc. TWO NOVELTIES in GENUS PLATYSTELE (ORCHIDACEAE

Lankesteriana International Journal on Orchidology ISSN: 1409-3871 [email protected] Universidad de Costa Rica Costa Rica Karremans, Adam P.; Bogarín, Diego TWO NOVELTIES IN GENUS PLATYSTELE (ORCHIDACEAE: PLEUROTHALLIDINAE) FROM COSTA RICA Lankesteriana International Journal on Orchidology, vol. 17, núm. 2, 2017, pp. 215-221 Universidad de Costa Rica Cartago, Costa Rica Available in: http://www.redalyc.org/articulo.oa?id=44353160009 Abstract Two new species of Platystele allied to the P. oxyglossa complex are described from Costa Rica. Platystele carl-lueriana can be distinguished from P. catiensis and P. oxyglossa by the compact inÀorescence that barely exceeds the leaf, from P. pedicellaris by the large plants with long leaves and small Àowers, and from P. tausensis by the yellowish sepals and petals ( vs . purple stained) and the minutely glandular ( vs. apically hirsute) lip. The second species, Platystele jane-lueriana, can be easily distinguished by the glabrous Àowers, and the conspicuously inÀated, bulbous lip, with an incurved apex. Among the other members of the complex, it is most closely resembles P. pedicellaris in the compact inÀorescence that is subequal to the leaves, but is distinguished by tail-less sepals and the linear-ligulate petals. With these additions, the total number of Costa Rican Platystele reaches twenty species. Keywords Flora of Costa Rica, new species, Platystele carl-lueriana, Platystele jane-lueriana, taxonomy.

Systematics and evolution of the genus Pleurothallis R. Br.

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind.

Wita Stwosza 59, 80-308 Gdańsk, Poland. [email protected] Abstract. The floristic, geographical and ecological analysis of the orchid flora of the department of Valle del Cauca are presented. The study area is located in the southwestern Colombia and it covers about 22 140 km2 of land across 4 physiographic units. All analysis are based on the fieldwork and on the revision of the herbarium material. A list of 572 orchid species occurring in the department of Valle del Cauca is presented. Two species, Arundina graminifolia and Vanilla planifolia, are non-native elements of the studied orchid flora. The greatest species diversity is observed in the montane regions of the study area, especially in wet montane forest.

A New Species of Jaltomata (Solanaceae) from Northwestern Peru
Brittonia,43(3), 1991, pp. 181-184. O 1991, by the New York Botanical Garden, Bronx, NY 10458-5126 A NEW SPECIES OF JALTOMATA (SOLANACEAE) FROM NORTHWESTERN PERU Knapp, Sandra (Institute for Botanical Exploration, Box EN, and Department of Biological Sciences, Box GY, Mississippi State, MS 39762), Thomas Mione (Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT 06269), and Abundio Sagdstegui A. (Universidad Antenor Orrego de Trujillo, Caqueti 280, Trujillo, Perl). A new species of Jaltomata (Solanaceae) from northwestern Perl. Brittonia 43: 18 1-184. 199 1. - Jaltomata whalenii, a rare species endemic to the Rio San Benito drainage in the department of Caja- marca, Perl, is described and illustrated. The delimitation and relationships of the genus Jaltomata are briefly discussed. Key words: Jaltomata, Solaneae, Solanaceae, Peru. Jaltomata includes about 25 species of tropical and subtropical herbs distrib- uted from the southwestern United States to Bolivia (Davis, 1980; Davis & Bye, 1982), on the islands of the West Indies (1 species; Adams, 1972) and on three of the Galapagos Islands (1 species; D'Arcy, 1982). The genus is characterized by: 1) basally articulated pedicels, 2) filaments inserted on the ventral face of the anthers, 3) basal enlargement of the filaments, 4) well developed nectariferous disk, 5) valvate corolla lobes, and 6) fruits with an accrescent calyx and juicy mesocarp (Hunziker, 19 79). The genus Jaltomata Schldl. has only recently been segregated from Saracha Ruiz & Pavbn, to which it is probably not closely related (Gentry, 1973). It includes all the herbaceous and suffrutescent species formerly included in Sar- acha (Gentry, 1973) and all species formerly known as Hebecladus Miers (Mac- bride, 1962; Hunziker, 1979).

This spe- cies is unique in that it has characteristics typical of both subgenera Scopula and Ancipitia. The plant has narrowly lanceolate leaves with a near-apical fascicle of single-flowered peduncles, previously only seen in Scopula. And, it has flowers with a minute, pubescent, tri-lobed lip in which the basal lobes are modified into ‘horns’, and an apical orifice in the central lobe, a feature previously only seen in Ancipitia. This intermediate morphology supports the previous suggestion that, at least based on morphology, the two subgenera should be combined.

Lepanthopsis Kayi (Pleurothallidinae, Orchidaceae), a New Species from Eastern Ecuador
LepaNTHOPSIS kayi (PLEUROTHALLIDINAE, ORCHIDACEAE), A NEW SPECIES FROM EASTERN ECUADOR LISA THOERLE1,2 AND XAVIER CORNEJO3 Abstract. Lepanthopsis kayi, a new species from the Amazonas region in Ecuador, is described, illustrated, compared with similar species, and its generic placement discussed. Lepanthopsis kayi is distinguished from all other species in the genus by the combination of ramicauls shorter than the leaf, with glabrous sheaths with the ribs and ostia thickened, and a very congested inflorescence bearing many overlapping, simultaneous flowers arranged in two opposite-facing ranks, the flowers with a proportionally very large, densely pubescent lip, ca. 50 percent longer than the lateral sepals. Keywords: Amazonas, Ecuador, Lepanthopsis, Orchidaceae, Platystele, Pleurothallidinae The genus Lepanthopsis (Cogn.) Ames contains ca. 44 the middle, emerging from a node below the apex of the species (Karremans, 2016), ranging in distribution from ramicaul; floral bracts thin, acuminate, 1–1.25 mm long; southern Mexico and southern Florida (U.S.A.) to the north, pedicels 0.75 mm long, bending sharply after emerging from through Central America and the Greater Antilles, and to the floral bract; ovary ribbed, 0.3 mm long, bent sharply Brazil and Bolivia in the south. The species are nearly evenly near the base. Flowers with sepals and petals translucent split between the American continents and the Greater yellow-green, glabrous, sepals with external, irregular, Antilles, where many are Hispañola endemics. In this paper, red blotches; sepals externally carinate, broadly elliptical, we describe a new species of Lepanthopsis, known from obtuse, 1-veined, dorsal sepal 1.25 mm long, 1 mm wide, the province of Pastaza in the Amazonas natural region of lateral sepals 1.2 mm long, 0.75 mm wide, connate 0.2 mm; Ecuador.
