A revision of Calyptrocalyx and the New Guinea species of Linospadix (Linospadicinae: Arecoideae: Arecaceae) is provided. For Calyptrocalyx, twenty-six species are recognised, and two for Linospadix. Three species, Calyptrocalyx amoenus, C. awa, and C. yamutumene are described as new. The following new combinations are made: Calyptrocalyx arfakianus, C. caudiculatus, C. flabellatus, C. geonomiformis, C. hollrungii, C. julianettii, C. lepidotus, C. merrillianus, C. micholitzii, C. multifidus, and C. pusillus which were formerly species of Paralinospadix. Neotypes are proposed for C. laulerbachianus, C. laxiflorus, C. pachystachys, C. pauciflorus, and C. polyphyllus. Linospadix has two species in New Guinea, L. albertisiana and L. canina.

A resistência de plantas jovens de açaí (Euterpe oleracea Mart.) à deficiência de água foi determinada em plantas de quatro meses de idade cultivadas em sacos plásticos perfurados contendo 7 kg de terra. O experimento foi conduzido em casa de vegetação e a irrigação foi suspensa até as plantas atingirem fotossíntese zero, quando, então, foram reidratadas. Durante este período foram feitas medidas diárias da fotossíntese líquida, condutância estomática e transpiração. Pequenas reduções na condutância estomática, transpiração e fotossíntese foram observadas a partir do décimo dia e se acentuaram com o tempo. A taxa de fotossíntese reduziu-se à metade da fotossíntese máxima quando o potencial de água atingiu -1,9 MPa. O estresse hídrico atingiu nível...

A palmeira Syagrus coronata, licuri, nativa do sertão baiano, é importante fonte de alimento para pessoas e animais. Sua amêndoa é usada como substituta do milho para a alimentação das aves. A composição nutricional indicou que o fruto é altamente calórico. Os principais constituintes das amêndoas são lipídeos e proteínas. Na polpa, o beta-caroteno é um importante constituinte. Discute-se a utilização dos frutos como complemento vitamínico de escolares da área rural da caatinga baiana.

It has been shown that the local extinction of large-bodied frugivores may cause cascading consequences for plant recruitment and overall plant diversity. However, to what extent the resilient mammals can compensate the role of seed dispersal in defaunated sites is poorly understood. Caviomorph rodents, especially Dasyprocta spp., are usually resilient frugivores in hunted forests and their seed caching behavior may be important for many plant species which lack primary dispersers. We compared the effect of the variation in seed mass of six vertebrate-dispersed plant species on the caching decision by the red-rumped agoutis Dasyprocta leporina Linnaeus, 1758 in a land-bridge island of the Atlantic forest, Brazil. We found a strong positive effect of seed...

We investigate palm species distribution, richness and abundance along the Mokoti, a seasonally-dry river of southeastern Amazon and compare it to the patterns observed at a large scale, comprising the entire Brazilian territory. A total of 694 palms belonging to 10 species were sampled at the Mokoti River basin. Although the species showed diverse distribution patterns, we found that local palm abundance, richness and tree basal area were significantly higher from the hills to the bottomlands of the study region, revealing a positive association of these measures with moisture. The analyses at the larger spatial scale also showed a strong influence of vapor pressure (a measure of moisture content of the air, in turn modulated by temperature) and...

El acopio esparcido ha recibido singular atención en las últimas décadas, y muchos estudios se han centrado en semillas de palmeras dispersadas por Dasyprocta. Nuestro objetivo fue identificar las especies consumidoras de frutos de Mauritia flexuosa, evaluar la importancia relativa de esas especies y el destino de las semillas dispersadas. Utilizamos experimentos de campo para evaluar el destino de las semillas removidas por frugívoros, en la Reserva de la Biosfera Pilón Lajas, Bolivia. Predijimos que las semillas enterradas por Dasyprocta tendrían menor mortalidad que las no enterradas. Colocamos 6-16 estaciones de frutos, con 15-50 frutos cada una, en cinco periodos de muestreo cubriendo un año. Los principales dispersores de M. flexuosa fueron D....

ABSTRACT The Brazilian Atlantic Forest is a global biodiversity hotspot, but most of what remains are small fragments. Small fragments are often harsh environments for forest plant recruitment due to edge effects and the loss of frugivorous animals that provide seed dispersal. We recorded the one-year reproductive phenology of the keystone palm Syagrus romanzoffiana in small (<2.5ha) Atlantic Forest fragments in southeastern Brazil. We tested the Janzen-Connell hypothesis with seed-removal experiments and followed the five-year survival of recruits in relation to the distance from parental plants. Palms produced many fruits throughout the year (mean 2,600/plant). More seedlings were found away from parental plants than near them, thereby supporting the...

Abstract The jelly palm plant [Butia capitata (Martius) Beccari] is a native palm of the Cerrado biome used for many purposes in northern Minas Gerais State, Brazil. Dormancy is common in palm seeds, resulting in slow and uneven germination that may take years to complete. Modification in the growth pattern, anatomical parameters, physiological and biochemical characteristics of the plant can be verified due to changes in the light spectrum transmitted through colored shade nets used. Therefore, the objective of this study is to evaluate the effect of colored shade nets on the leaf and root anatomy of the jelly palm plant. The experiment was performed in a completely randomized design, with five treatments, ten replicates and eight plants per replicate,...

The distinction between Butia capitata and B. odorata is based only on a few morphological characteristics, therefore there is a need for additional studies for supporting the separation of the species. As lamina anatomy characteristics are relevant in circumscribing Arecaceae taxa, this work aimed to describe B. capitata lamina anatomy and compare it with B. odorata. Samples from the middle portion of the pinnae were collected and processed in accordance with standard plant anatomy techniques. The epidermis is uniseriate and composed of a thick cuticle and epicuticular waxes into like hooked filaments. The subsidiary cells that arch over the guard cells are located at the hypodermis. The mesophyll is isobilateral and compact. The vascular bundles are...

Unlike other arboreal monocotyledons, the secondary growth of palms has for the past 100 years been described as diffuse. Solely cell enlargement and random parenchyma divisions, without the activity of a meristem, characterize such growth. Some previous works of the early 20th century have, however, mentioned the presence of a secondary meristem in the stems of palms, but this information was forgotten since then. Addressing to this question, we analysed palm stems of four species, with the aim to understand the possible presence of such secondary growth. We found that a meristematic band occurs between the cortex and the central cylinder and gives rise to new vascular bundles and parenchyma internally, producing parenchyma and fibres externally. It...

This study examines aspects of the stem density and growth of two large arborescent palms Attalea maripa and Astrocaryum aculeatum and discusses their implication for the palm trees distribution in Amazonia. Stem density and growth were investigated through both laboratory measurements and field estimates of growth rates. The densities of stem samples collected within one individual of each studied species were very distinct. The samples of A. maripa stem were more homogeneous in density than those of A. aculeatum, both from the internal to the external, and from the lower to the upper parts of the stem. Field estimates of stem growth rates revealed that A. maripa growth is also more constant through development in height. Short A. aculeatum palms had...
