Herendeen1,* and Fabiany Herrera* *Chicago Botanic Garden, 1000 Lake Cook Road, Glencoe, Illinois 60022, USA Editor: Michael T. Dunn Premise of research. Fossil leaves from the early Eocene Green River Formation of Wyoming and late Eo- cene Florissant Formation of Colorado have been studied and described here as two species in the monospe- cific extant genus Arcoa (Leguminosae, subfamily Caesalpinioideae). The single living species of Arcoa is en- demic to the Caribbean island of Hispaniola. The species from Florissant has been known since the late 1800s but has been incorrectly treated as several different legume genera. Methodology. The compression fossils were studied using standard methods of specimen preparation and microscopy. Fossils were compared with extant taxa using herbarium collections at the Field Museum and Smithsonian Institution. Pivotal results. The fossil bipinnate leaves exhibit an unusual morphological feature of the primary rachis, which terminates in a triad of pinnae, one terminal flanked by two lateral pinnae, all of which arise from the same point at the apex of the rachis. This feature, combined with other features that are diagnostic of the family Leguminosae or subgroups within it, allows the taxonomic affinities of the fossil leaves to be definitively deter- mined as representing the extant genus Arcoa, which is restricted to the Caribbean island of Hispaniola today. -

We determine the karyotype and the chromosome morphometry in five Caesalpinia s.l. spp., and we describe the heterochromatin pattern in four of them. The diploid chromosome number of 24 was reported for the first time in Caesalpinia calycina, Caesalpinia microphylla and Caesalpinia pluviosa var. peltophoroides, and confirmed in Caesalpinia ferrea var. leiostachya and Caesalpinia pulcherrima. Different karyotype formulae were obtained for each of these five species. -

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer. -
Biodiversity in Forests of the Ancient Maya Lowlands and Genetic
Biodiversity in Forests of the Ancient Maya Lowlands and Genetic Variation in a Dominant Tree, Manilkara zapota (Sapotaceae): Ecological and Anthropogenic Implications by Kim M. Thompson B.A. Thomas More College M.Ed. University of Cincinnati A Dissertation submitted to the University of Cincinnati, Department of Biological Sciences McMicken College of Arts and Sciences for the degree of Doctor of Philosophy October 25, 2013 Committee Chair: David L. Lentz ABSTRACT The overall goal of this study was to determine if there are associations between silviculture practices of the ancient Maya and the biodiversity of the modern forest. This was accomplished by conducting paleoethnobotanical, ecological and genetic investigations at reforested but historically urbanized ancient Maya ceremonial centers. The first part of our investigation was conducted at Tikal National Park, where we surveyed the tree community of the modern forest and recovered preserved plant remains from ancient Maya archaeological contexts. The second set of investigations focused on genetic variation and structure in Manilkara zapota (L.) P. Royen, one of the dominant trees in both the modern forest and the paleoethnobotanical remains at Tikal. We hypothesized that the dominant trees at Tikal would be positively correlated with the most abundant ancient plant remains recovered from the site and that these trees would have higher economic value for contemporary Maya cultures than trees that were not dominant. We identified 124 species of trees and vines in 43 families. Moderate levels of evenness (J=0.69-0.80) were observed among tree species with shared levels of dominance (1-D=0.94). From the paleoethnobotanical remains, we identified a total of 77 morphospecies of woods representing at least 31 plant families with 38 identified to the species level. -
Karyomorphology and Karyotype Asymmetry in the South American Caesalpinia Species (Leguminosae and Caesalpinioideae)
Karyomorphology and karyotype asymmetry in the South American Caesalpinia species (Leguminosae and Caesalpinioideae) P.S. Rodrigues, M.M. Souza and R.X.

Corrêa E-mail: [email protected] Genet. Mol. Res. 13 (4): 8278-8293 (2014) Received May 7, 2013 Accepted June 10, 2014 Published October 20, 2014 DOI http://dx.doi.org/10.4238/2014.October.20.4 ABSTRACT. With the purpose of addressing the pattern of karyotype evolution in Caesalpinia species, chromosome morphology was characterized in five species from Brazil, and karyotypic asymmetry was analyzed in 14 species from South America. All accessions had the chromosome number 2n = 24, which was first described here for Caesalpinia laxiflora Tul. and Cenostigma macrophyllum Tul. The karyotype formula of C. laxiflora, Caesalpinia pyramidalis Tul., and C. macrophyllum was 12 m. The formula varies amongst the populations of Caesalpinia bracteosa Tul. (11 m + 1 sm) and Caesalpinia echinata Lam. (10 m + 2 sm and 9 m + 3 sm). The intra- and interspecific variations in chromosome length were significant (analysis of variance, P < 0.05). Analyzing the asymmetry index (AI), revealed that Caesalpinia calycina Benth. had the most asymmetrical karyotype (AI = 10.52), whereas Caesalpinia paraguarienses (D. Parodi) Burkat. and Caesalpinia gilliesii (Hook.) Benth. had the most symmetrical karyotypes (AI = 0.91 and 1.10, respectively). There has been a trend to lower AI values for the Caesalpinia s.l. species assigned in Libidibia and intermediate values for those combined into Poincianella. -

Libidibia Paraguariensis, Fabaceae
Bol. Soc. Argent. Bot. 52 (1) 2017 A. M. Giménez et al. - Ecoanatomía de Libidibia paraguariensisISSN 0373-580 X Bol. Soc. Argent. Bot. 52 (1): 45-54. 2017 Ecoanatomia del ébano sudamericano: “guayacán” (Libidibia paraguariensis, Fabaceae) ANA M. GIMÉNEZ1, GRACIELA BOLZON MUNIZ2, JUANA G. MOGLIA1 y SILVANA NIGOSKY2 Summary: Ecoanatomy of southamerican ebony, ‘guayacán’ (Libidibia paraguariensis, Fabaceae). The wood of Libidibia paraguariensis (D. Parodi) G. P. Lewis, “guayacan” is homologous to that of Diospyros ebenum J. Koenig “ebony”. It is a wood with technological and organoleptic characteristics that give excellent quality and significant future potential. For this reason study objectives were: (1) deepen the knowledge of anatomical qualities of the wood and bark; (2) analyze sapwood-heartwood ratio, and (3) characterize the growth rings. The study was conducted using samples from Guasayán, Santiago del Estero, and Villa Rio Bermejito, Chaco (Argentina). Six trees from each site were selected randomly. A wood disk from the main shaft of each individual, at a height of 1.3 m was achieved. The description of the wood and bark was performed. The relevant anatomical character with high diagnostic value was full stratification of radios. The rings are demarcated, with an average radial increment (RI) average 3.57 mm, the growth is slow-medium, with thick sapwood. The xylem has corresponding features to a mesomorphic species. The outer bark with one or two accumulated periderms, presents dehiscence in thin plates, which is a diagnostic element for field determination. Key words: Libidibia paraguariensis, bark, growth rings, heartwood, sapwood, xylem. Resumen: La madera de Libidibia paraguariensis (D. -
Trees in Singapore in 2017 GRAHAM BAKER Visited Singapore; the Following Are His Notes on Some of the Trees He Admired There
Trees in Singapore In 2017 GRAHAM BAKER visited Singapore; the following are his notes on some of the trees he admired there. A city in a garden In June 1963, Lee Quan Yew planted a Mempat tree (Cratoxylum formosum), a pink flowering, medium-sized, native tree, marking the start of his initiative to transform Singapore into a garden city. Since then, so many trees have been planted that his dream has become a reality. High rise condominiums, hotels and offices are enveloped in a green forest comprised principally of two species: the magnificent Angsana Pterocarpus( indicus) a tall, awe inspiring tower of green, billowing elm-like at the top, a southeast Asia species; and the spreading South American rain tree (Samanea saman) festooned in a clothing of epiphytes. A variety of other species complete the ‘forest’ including Singapore’s native favourite, the Tembusu (Fagraea fragrans). This tall, neat tree flowers in spring and late autumn (although there are no seasons in Singapore!) with small- ish, cream, highly scented flowers. Yellow flame (Peltophorum pterocarpum) is here too: a tall, spreading, southeast Asian tree, with pinnate leaves and yellow flowers. Tropical trees, to flower spectacularly, need a spell of dry weather which 210 Singapore doesn’t have. So flowering is sporadic, a branch here, a tree there, at random times. So flowering was sparse when I visited: some yellow flame trees had a partly yellow crown, whilst tropical shrubs coloured the pavements, particularly the lovely red Caesalpinia pulcherrima (from tropical America) and yellow Cassia species. To see avenues of rain trees arching over the highway is a magnificent sight. -
