(Orchidaceae: Pleurothallidinae) from Península De Osa, Puntarenas, Costa Rica
A NEW LEPANTHES (ORCHIDACEAE: PLEUROTHALLIDINAE) FROM PENÍNSULA DE OSA, PUNTARENAS, COSTA RICA ISLER F. CHINCHILLA,1–3 REINALDO AGUILAR,4 AND DIEGO BOGARÍN1,5,6 Abstract. Lepanthes is one of the most species-rich genera of orchids in the Neotropics, with most of the species found in medium to high elevation forests and few species in lowlands. We describe and illustrate Lepanthes osaensis, a new species from the very wet lowland forest of Península de Osa, Costa Rica. It is similar to Lepanthes cuspidata but differs mostly in the vinous leaves; smaller sepals; the narrower, bilobed petals; and the smaller lip with triangular blades. Notes on its distribution, habitat, flowering, and conservation status, as well as discussion of a taxon with similar morphology, are provided. Keywords: Lepanthes cuspidata, orchid endemism, Pleurothallidinae taxonomy, twig epiphytes, very wet lowland forest Lepanthes Sw. is one of the most species-rich genera of Jiménez and Grayum, 2002; Bogarín and Pupulin, 2007; Pleurothallidinae (Orchidaceae), with over 1200 species Rakosy et al., 2013) and the continued long-term fieldwork from southern Mexico and the Antilles to Bolivia and by the second author (RA). A possible explanation is the northern Brazil (Pridgeon, 2005; Luer and Thoerle, 2012; marked seasonality between dry and wet seasons from Vieira-Uribe and Moreno, 2019; Bogarín et al., 2020). the north toward the central Pacific, contrasting with Lepanthes comprises plants with ramicauls enclosed by the prevailing wet conditions in the Caribbean throughout several infundibular sheaths, named “lepanthiform sheaths,” the year (Kohlmann et al., 2002). The most suitable areas racemose inflorescences of successive flowers, subsimilar, for lowland Lepanthes in the Pacific are the tropical wet glabrous sepals, petals wider than long, frequently bilobed forests from Carara in the central Pacific to Península with divergent lobes, the lip usually trilobed with the lateral de Osa and Burica. -

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al. -

Floristic Inventory of One Hectare of Palm-Dominated Creek Forest in Jenaro Herrera, Peru

M. PRICKETT1 , 2 ,E.N.HONORIO C.3 ,Y.BABA1 ,H.M.BADEN1 , C. M. ALVEZ V.2 &C.A.QUESADA4 A floristic inventory was carried out in an area of palm-dominated creek forest in Jenaro Herrera, in the northeast of Peru. All trees $ 10 cm dbh were surveyed in a one-hectare permanent plot using the standard RAINFOR methodology. There were 618 individuals belonging to 230 species, 106 genera and 43 families. The results showed that the total basal area of the trees in the plot was 23.7 m2. The three species with the highest importance value indexes were Iriartea deltoidea Ruiz & Pav., Oenocarpus bataua Mart. (Arecaceae) and Carapa procera DC. (Meliaceae). The five most dominant families in order of importance were Arecaceae, Fabaceae, Meliaceae, Euphorbiaceae and Sapotaceae. Although the soil of this plot was poorly drained, the number of trees and the diversity of the plot were typical for terra firme forest in the western Amazon. Keywords. Amazonia, diversity, floristic composition, permanent sample plot, terra firme forest. Introduction The neotropical Amazon rainforest covers 757 million hectares in total (Eden, 1990). This rainforest is a rich, heterogeneous patchwork of distinct forest types, and its floristic variability is affected by a combination of climatic, edaphic and ecological variables (Gentry, 1988; Pitman et al., 2001; Vormisto, 2002; ter Steege et al., 2003; Macı¤a & Svenning, 2005; Haugaasen & Peres, 2006; Honorio et al., 2009). -

388 Desiccation tolerance of Tapirira obtusa seeds collected from different environments1 Wilson Vicente Souza Pereira2*, José Márcio Rocha Faria2, Olivia Alvina Oliveira Tonetti2, Edvaldo Aparecido Amaral da Silva3 ABSTRACT – This study was aimed at evaluating the desiccation sensitivity in seeds of the tree Tapirira obtusa (Benth.) J. D. Mitchell collected from three different environments and subjected to two distinct drying speeds. Seeds were collected from a rocky area, in the “Cerrado”, and in a riparian forest area, in the region of municipality of Lavras, State of Minas Gerais. The seeds were subjected to drying with magnesium chloride (slow drying) or silica gel (fast drying), into closed environment, until moisture contents of 40%, 30%, 20% and 10%, considering as control, the percentage of germination at the initial moisture content in each environment, which varied from 47% to 50%. Percentages of germination and normal seedlings as well as germination speed index were assessed. For the three environments studied, there was no effect of slow drying on seed germination. Seeds from area of Cerrado, however, have shown a slight reduction on germination when subjected to fast drying. Oppositely, seeds from rocky area had germination increased when subjected to fast drying. Seeds from riparian forest area had no reduction on germination percentage, independent of drying speed. Results suggest that seeds of T. obtusa are not sensitive to desiccation. Index terms: drying, germination, sensitivity, dehydration.

V., Mesones, I., García-Villacorta, R., Arévalo, F. R. R. and Baker, T. R. 2017. Peatland forests are the least diverse tree communities documented in Amazonia, but contribute to high regional beta-diversity. – Ecography doi: 10.1111/ecog.03126 Supplementary material Appendix 1 Non-peatland forest type dataset descriptions Seasonally-flooded forest plot data came from the published dataset of Honorio Coronado et al. (2015). These 11 plots were 0.5 ha in area and based on the RAINFOR protocol (Phillips et al. 2009), whereby all trees with a diameter at breast height (dbh) ≥ 10 cm were measured and identified. White-sand forest data came from a number of data sources. Data from 16 white-sand forest plots came from the published dataset of Fine et al. (2010). Thirteen of these plots consist of 0.1 ha forest plots in varillal type forests (defined by a canopy height 10-20 m [García Villacorta et al. 2003]), where all trees ≥ 5 cm dbh were identified and specimens collected. A further three 0.025 ha plots were established by Fine et al in extremely stunted chamizal type forest (defined by a canopy lower than 5 m [Encarnación 1985, García Villacorta et al. 2003]). Due to the small size classes found in these chamizal forests, all trees ≥ 2.5 cm dbh were identified and specimens were collected. A further eight plots completed the dataset from white sand forest: four were 0.1 ha plots established by O.
