It reaches a height of 12–15 m, its leaflets are clustered, it is hermaphroditic but changes sex expressions as it grows older, and its pollination involves various insect species that depend on it for their survival (Voeks, 1988, 2002; Hen- derson et al., 1995).

  • Phytelephas Aequatorialis in PALM BEACH COUNTY
    GROWING Phytelephas aequatorialis IN PALM BEACH COUNTY Submitted by Charlie Beck Phytelephas aequatorialis is a large, solidary, pinnate palm. Its leaflets may be regularly arranged in a single plain, or they can be grouped and arranged in several planes. This is the tallest of the six Phytelephas species, it can grow 45’ tall but often tops out at 10’. This height refers to palms growing in its tropical, native habitat. In Palm Beach County it is a slow growing palm so don’t expect rapid vertical growth. In habitat fronds can measure up to 30’ long, even though stems only grow to one foot in diameter. Native habitat ranges from wet, coastal plain to 5000’ elevation on the western Andes slope in Columbia, Ecuador and Peru. Most often, P. aequatorialis is found in large stands along river banks. Seed is often dispersed by flood water. The common name for this palm is the Ecuadorean Ivory Palm. Its seed is white and very hard. P. aequatorialis is the source of vegetable ivory in Ecuador. Artisans carve figurines from this vegetable ivory. Buttons are also made from this seed. Being a dioecious palm only female plants produce vegetable ivory. Back in the 1990’s, the past president of our Society, Dale Holton, imported vegetable ivory carvings directly from Ecuador. Dale established a relationship with the exporter and eventually obtained some habitat collected seed for growing at Holton Nursery. Some of us palm enthusiasts were lucky to purchase this relatively rare palm from Dale. It was unknown if this tropical palm would grow in Palm Beach County.

  • A Review of Animal-Mediated Seed Dispersal of Palms
    Selbyana 11: 6-21 A REVIEW OF ANIMAL-MEDIATED SEED DISPERSAL OF PALMS SCOTT ZoNA Rancho Santa Ana Botanic Garden, 1500 North College Avenue, Claremont, California 91711 ANDREW HENDERSON New York Botanical Garden, Bronx, New York 10458 ABSTRACT. Zoochory is a common mode of dispersal in the Arecaceae (palmae), although little is known about how dispersal has influenced the distributions of most palms. A survey of the literature reveals that many kinds of animals feed on palm fruits and disperse palm seeds. These animals include birds, bats, non-flying mammals, reptiles, insects, and fish. Many morphological features of palm infructescences and fruits (e.g., size, accessibility, bony endocarp) have an influence on the animals which exploit palms, although the nature of this influence is poorly understood. Both obligate and opportunistic frugivores are capable of dispersing seeds. There is little evidence for obligate plant-animaI mutualisms in palm seed dispersal ecology. In spite of a considerable body ofliterature on interactions, an overview is presented here ofthe seed dispersal (Guppy, 1906; Ridley, 1930; van diverse assemblages of animals which feed on der Pijl, 1982), the specifics ofzoochory (animal­ palm fruits along with a brief examination of the mediated seed dispersal) in regard to the palm role fruit and/or infructescence morphology may family have been largely ignored (Uhl & Drans­ play in dispersal and subsequent distributions. field, 1987). Only Beccari (1877) addressed palm seed dispersal specifically; he concluded that few METHODS animals eat palm fruits although the fruits appear adapted to seed dispersal by animals. Dransfield Data for fruit consumption and seed dispersal (198lb) has concluded that palms, in general, were taken from personal observations and the have a low dispersal ability, while Janzen and literature, much of it not primarily concerned Martin (1982) have considered some palms to with palm seed dispersal.

ABSTRACT Introduction: Understanding the phenology of plant populations is vital for their conservation and management. We studied the vegetative and reproductive phenology of the endangered palm Ceroxylon quindiuense along an altitudinal gradient in the Central Cordillera of Colombia. Objective: We describe the leaf production rate, and flowering and fruiting cycles, and calculate food offer for the fauna, as a tool for the proper management of the palm. Methods: At each sampling site (2 400, 2 600, 2 800, 3 000 m.a.s.l.), we marked 40 adult individuals (20 pistillate, 20 staminate), which we followed bimonthly for 24 months.

The flowering behaviour of palm species may be a useful indicator of phylogenetic relationships and therefore evolutionary events. This paper presents a detailed histological study of reproductive development in coconut (Cocos nucifera L.), from initiation up to maturation of staminate and pistillate flowers. Reproductive development in coconut consists of a sequence of individual events that span more than two years. Floral morphogenesis is the longest event, taking about one year, while sex determination is a rapid process that occurs within one month. The inflorescence consists of different ultimate floral structural components. Pistillate flowers are borne in floral triads that are flanked by two functional staminate flowers.

E-mail: [email protected] Abstract A taxonomic revision of the Neotropical palm genus Leopoldinia based on morphological data and morphometric methods was carried out. One hundred and sixteen herbarium specimens were scored for seven qualitative and 24 quantitative variables. Qualitative variables were divided into six characters and one trait. Using the Phylogenetic Species Concept, the six characters were used to recognize three species. These are widely distributed in the central Amazon region of Brazil and adjacent Venezuela and Colombia. Nomenclature, descriptions, illustrations, and distribution maps are provided for each taxon. Key words: Palmae, morphometrics, Neotropics, Rio Negro Introduction The small, Neotropical genus Leopoldinia Martius (1823–1837: 58) comprises just three species confined to the central Amazon region. So different is the morphology of the genus from related genera, especially the elaborate leaf sheaths and trilocular, triovulate gynoecium, that the genus has been placed in its own tribe of the Arecoideae, the Leopoldinieae (Dransfield et al. 2008). This tribe, along with the Areceae, Euterpeae, Geonomateae, Manicarieae and Pelagodoxeae, make up the ‘core arecoid clade’ (Dransfield et al. 2008), although relationships amongst these tribes are not well resolved (Baker et al. 2009, Baker et al. 2011). While there have never been any problems with generic delimitation, there are doubts over species boundaries in Leopoldinia. Martius described two species, L.
