Itaya amicorum LC Taxonomic Authority: H.E.Moore. Global Assessment Regional Assessment Region: Global Endemic to region Upper Level Taxonomy Kingdom: PLANTAE Phylum: TRACHEOPHYTA Class: LILIOPSIDA Order: ARECALES Family: PALMAE Lower Level Taxonomy Rank: Infra- rank name: Plant Hybrid Subpopulation: Authority: General Information Distribution Itaya amicorum is confined to the western amazon region in Colombia (Amazonas), Peru (Loreto) and Brazil (Amazonas) (Henderson et al. 1997). Range Size Elevation Biogeographic Realm Area of Occupancy: Upper limit: 300 Afrotropical Extent of Occurrence: 60574 Lower limit: 0 Antarctic Map Status: Depth Australasian Upper limit: Neotropical Lower limit: Oceanian Depth Zones Palearctic Shallow photic Bathyl Hadal Indomalayan Photic Abyssal Nearctic Population Number of individuals is not known. It has been reported as uncommon in the understory and has a patchy distribution (Henderson et al. 1997). From recent surveys of the type location along the Rio Itaya in Peru, Stauffer (pers. comm. 2009) reports that the species was rare. From several transects taken in 2006, Balslev et al identified populations upstream from Negro Urco, Peru. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology Palm with a solitary stem, up to 4m tall. Occurs in lowland rain forest below 300m, growing both in non-inundated areas and in wet places along rivers (Henderson et al. 1997). System Movement pattern Crop Wild Relative Terrestrial Freshwater Nomadic Congregatory/Dispersive Is the species a wild relative of a crop? Marine Migratory Altitudinally migrant Growth From Definition Tree - large Large tree, also termed a Phanerophyte (>1m) Threats General threats to the habitat in which I. amicorum resides include: logging, cattle ranching, large–scale agriculture such as coca (Erythroxylum coca) production, mining and industrial development. These threats have damaged huge tracks of land and recently are advancing on the relatively stable/intact ecoregions such as the Solimoes-Japurá moist forest (WWF 2001). Past Present Future 1 Habitat Loss/Degradation (human induced) 1.1 Agriculture 1.3 Extraction 1.3.1 Mining 13 None Conservation Measures The conservation status of I. amicorum was assessed in the 1997 Red List as Rare, Endangered and Rare, respectively in Brazil, Colombia and Peru (Walter and Gillett 1998). It was assessed in the The World List of Threatened Trees as Data Deficient (Bernal 1998). Subsequently is has been assessed in Colombia as Least Concern (Bernal & Galeano 2006). I. amicorum is protected in Colombia as it is known from a remote locality in a national park (Bernal 1998). It is not listed on CITES and seeds from this species are not present in the Millennium Seed Bank, UK. Monitoring of the population is encouraged to better understand the status of this species at each sub-population. Although no specific plans exist to conserve species I. amicorum, there are ongoing International Tropical Timber Organization (ITTO) projects in the Non Timber Forest Products in the Amazon. A project entitled "Non-timber Production and Sustainable Development in the Amazon" is in place and has a budget of US$387,185 and the implementing agency is the University of Brasilia. The mission of ITTO is "to facilitate discussion, consultation and international cooperation on issues relating to the international trade and utilisation of tropical timber and the sustainable management of its resource base" (Hwan Ok Ma 2002).

Possibly Extinct Candidate? Rationale for the Red List Assessment The Colombian and Brazilian subpopulations of I. amicorum reside in relatively stable/intact ecoregions and in Colombia this palm is reported to be present in a remote locality in a national park (Bernal 1998). The Peruvian subpopulation however, resides in the vulnerable Napo moist forests and the Vulnerable Iquitos varzea ecoregions, which are threatened by ongoing human activities such as logging, cattle ranching, large–scale agriculture such as coca (Erythroxylum coca) production, mining and industrial development (WWF 2001). At present I. amicorum does not meet the criteria for a threatened category. However, the Peru subpopulation appears to be under some threat and in decline, especially in the Rio Itaya region. Monitoring of populations should be carried out in all three subpopulations to better determine its status.

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.

  • Itaya Amicorum in PALM BEACH COUNTY

    Itaya Amicorum in PALM BEACH COUNTY

    GROWING Itaya amicorum IN PALM BEACH COUNTY Submitted by Charlie Beck Itaya amicorum is native to restricted areas of Columbia, Peru, and Brazil. It grows in wet areas along rivers and streams, and also grows away from water courses at elevations up to 1000 feet. This is a tropical rainforest palm which was discovered and named in 1972. This palm is critically endangered due to land clearing. Itaya amicorum is a solitary, palmate palm. Its leaves resemble large pinwheels similar to those of a large Licuala peltata although the petioles are unarmed. The leaf undersides are silvery gray or white. There is only one species identified in the genus Itaya. This palm is most closely related to Chelyocarpus but can be easily distinguished by its split petiole bases similar to palms in the genus Thrinax. Itaya amicorum is a monoecious palm with showy white, hermaphroditic flowers. In habitat these palms top out at 15’ tall on stems which measure 3-4” in diameter. Six foot diameter leaves are held on 7-8’ long petioles. More than 20 years ago I was shopping for palms at a South Florida Palm Society Sale located at Fairchild Tropical Botanic Garden. I was there at the sale opening early Saturday morning. I was with all of the other palm enthusiasts, running from booth to booth trying to locate the rarest of rare palms. I overheard two of the vendors talking about someone was selling a small Itaya amicorum for $350. At that time I didn’t know this palm, nor was I willing to pay $350 for such a small specimen.

    Cacao and Its Allies

    CACAO AND ITS ALLIES A TAXONOMIC REVISION OF THE GENUS THEOBROMA Jose Cuatrecasas Introduction "Celebrem etiam per universam Americam multique usua fructum Cacao appellatum." Clusius, 1605. "Cacao nomen barbarum, quo rejecto Theobroma dicta est arbor, cum fructus basin sternat potioni delicatissimae, Baluberrimae, maxime nutrienti, chocolate mexicanis, Euro- paeis quondam folis Magnatis propriae (ffpotfta rwf 8&av, Vos Deos feci dixit Deus de imperantibus), licet num vilior fact a." Linnaeus, Hort. Cliff. 379. 1737. Theobroma, a genus of the family Sterculiaceae, is particularly noteworthy because one of its members is the popular "cacao tree" or "cocoa tree." The uses and cultivation of this outstanding tropical plant were developed in the western hemisphere by the Mayas in Central America a long time before Europeans arrived on the con- tinent. The now universally used name cacao is derived directly from the Nahuatl "cacahuatl" or "cacahoatl," just as the name of the popular drink, chocolate, is derived from "xocoafcl" or "chocoatl." The economic importance of cacao has given rise to great activity in several fields of development and research, especially in agronomy. Historians and anthropologists have also been very much interested in learning the role played by cacao in the economy and social relations of the early American populations. There exists today an extensive literature devoted to the many problems related to cacao. I saw cacao for the first time in Colombia in 1932, but became actually interested in the genus in 1939 and the years following, when I found cacao trees growing wild in the rain forests of the Amazonian basin. I was fascinated by the unique structure of the flowers of the cocoa tree, and its extraordinary fruit.

We detected HCN production in only two species of one genus, Drymophloeus. Additional smaller surveys of shoot meristems and roots revealed cyanogenesis only in the shoot meristem of one species of Dypsis. Our results indicate that cyanogenesis is rather rare in the family.

Introduction Cyanide production is a widespread phenomenon in plants, with cyanogenic compounds present in many species across the plant kingdom (Hegnauer, 1977). These compounds are often ecologically signi"cant and can be hazardous to human health when they occur in crop plants. Although cyanogenesis has arisen indepen- dently in several lineages, it is a good taxonomic marker for several groups of plants (e.g., Passi#oraceae; Olafsdottir et al., 1989). Cyanogenic plants typically store cyanide in the form of cyanogenic glycosides. These plants release HCN only after tissue damage brings apoplastic {-glucosidases into contact with vacuolar glycosides. Some phenotypically acyanogenic plants * Corresponding author.
