Schlechter from plants collected in Costa Rica by Karl Werckle is presented. Lectotypification is provided for 60 of the 84 species. Previously lectotypified species, based on syntypes, including collections by Werckle, and neotypified taxa, are recorded, and bibliographical references to the designations of lectotypes and neotypes are provided. Neotypes are selected for eight species, for which no isotypes, paratypes or other material associated with the protologue are known to exist. Illustrations of most of the lectotypes are provided. Epidendrum amparoanum, Pachystele densa and Trigonidium amparoanum are not typified because of lack of appropriate material and because of taxonomic uncertainties.

Epidendrum fulfordianum is compared with E. chlorocorymbos, from which it can be distinguished by the much larger flowers, the wider petals and entire, subrectangular, retuse-mucronate midlobe of the lip. Similar to E. barbeyanum, the smaller E. pseudobarbeyanum can be easily distinguished by the short and straight, few-leaved stems, the few-flowered inflorescence, and the distinctly smaller flowers. A third species, Epidendrum villotae, is recorded and illustrated on the basis of a Costa Rican specimen.1 aPupulin, Franco1 aKarremans, Adam  u<Go to ISI>://BCI:BCI20100052704000574nas a2200157   4500008004100000022001400041245015100055210006900206300001200275490000800287100001900295700002400314700002200338700001800360856003800378       2010                        eng d  a0024-407400aThe incidence of crassulacean acid metabolism in Orchidaceae derived from carbon isotope ratios: a checklist of the flora of Panama and Costa Rica0 aincidence of crassulacean acid metabolism in Orchidaceae derived  a194-2220 v1631 aSilvera, Katia1 aSantiago, Louis, S.1 aCushman, John, C.1 aWinter, Klaus  u<Go to ISI>://WOS:00027915800000603009nas a2200145   4500008004100000022001400041245010200055210006900157300001000226490000800236520253000244100002802774700002302802856003802825       2010                        eng d  a1385-023700aThe nutrient status of epiphytes and their host trees along an elevational gradient in Costa Rica0 anutrient status of epiphytes and their host trees along an eleva  a25-370 v2073 aVascular epiphytes are a conspicuous and highly diverse group in tropical wet forests; yet, we understand little about their mineral nutrition across sites. In this study, we examined the mineral nutrition of three dominant vascular epiphyte groups: ferns, orchids, and bromeliads, and their host trees from samples collected along a 2600 m elevational gradient in the tropical wet forests of Costa Rica. We predicted that the mineral nutrition of ferns, orchids, and bromeliads would differ because of their putative differences in nutrient acquisition mechanisms and nutrient sources-atmospherically dependent, foliar feeding bromeliads would have lower nitrogen (N) and phosphorous (P) concentrations and more depleted delta(15)N values than those in canopy soil-rooted ferns because canopy soil is higher in available N, and more enriched in delta(15)N than the atmospheric sources of precipitation and throughfall. We also predicted that epiphyte foliar chemistry would mirror that of host trees because of the likely contribution of host trees to the nutrient cycle of epiphytes via foliar leaching and litter contributions to canopy soil. In the same vein, we predicted that epiphyte and host tree foliar chemistry would vary with elevation reflecting ecosystem-level nutrients-soil N availability increases and P availability decreases with increasing elevation. Our results confirmed that canopy soil-rooted epiphytes had higher N concentrations than atmospheric epiphytes; however, our predictions were not confirmed with respect to P which did not vary among groups indicating fixed P availability within sites. In addition, foliar delta(15)N values did not match our prediction in that canopy soil-rooted as well as atmospheric epiphytes had variable signatures. Discriminant function analysis (DFA) on foliar measurements determined that ferns, orchids, and bromeliads are statistically distinct in mineral nutrition. We also found that P concentrations of ferns and orchids, but not bromeliads, were significantly correlated with those of host trees indicating a possible link in their mineral nutrition's via canopy soil. Interestingly, we did not find any patterns of epiphyte foliar chemistry with elevation. These data indicate that the mineral nutrition of the studied epiphyte groups are distinct and highly variable within sites and the diverse uptake mechanisms of these epiphyte groups enhance resource partitioning which may be a mechanism for species richness maintenance in tropical forest canopies.1 aCardelus, Catherine, L.1 aMack, Michelle, C.  u<Go to ISI>://WOS:00027421180000300505nas a2200097   4500008004100000245011000041210006900151300001200220100003100232856014400263       2010                        eng d00aA new species of Zamia (Zamiaceae) from Costa Rica.
