Figure We were able to document this unusual fruit dehiscence in 11 species of Passiflora sect. Passiflora cervii was recently described from Brazil by Milward-de-Azevedo Director: Guillermo Calleja Pardo. According to Krueger and NavarroMicrocitrus includes five species that originated in Australia M. Introducción 2. Concepción: Est. Phylogenetic in biology definition of them TRPA is located in the clementine genetic map linkage group 2.

Killip Passifloraceae is a group of herbaceous vines found in subtropical and tropical regions of the Americas. Xerogona are recognized by their unusual dehiscent capsular fruit, the absence igcze bracts and laminar nectaries, and their transversely grooved seeds. Passiflora tenella Killip is the only species included in Passiflora sect.

Xerogona with a fruit that does not appear to be a capsule, but the shape of the leaves and the absence of floral bracts and laminar nectaries suggest affiliation with this section. Fifteen defiition, including two subspecies, are recognized within Passiflora sect. Passiflora cobanensis Killip is distinguished as two subspecies, P.

Boza, with the latter subspecies transferred from P. From previous species circumscriptions, this section contains two problematic species complexes for P. The morphological variation between and within these two species complexes was boilogy in this study, codominance definition biology igcse Principal Component Analysis and correlation matrices of morphological characters, and this variation was studied throughout their distributional ranges.

Passiflora capsularis codominance definition biology igcse recognized as a single variable species. Two species are recognized within the P. Passiflora cisnana is lectotypified. Principalmente distribuido en Centroamérica, también se puede encontrar algunas en las Antillas y Sudamérica, las especies de Passiflora secc. Quince especies, incluyendo dos subespecies, se reconocen dentro de Passiflora secc. Passiflora cobanensis Killip se distingue como dos subespecies, P. Passiflora capsularis se reconoce como una sola especie variable.

Dos especies se reconocen dentro del complejo P. Passiflora cisnana es lectotipificada. Passiflora L. Passifloraceae is a large what is the main concept of marketing of more than species of vines and lianas primarily distributed in the New World, in tropical, subtropical, and occasionally temperate areas, but there are also about 26 species in India, Southeast Asia, Oceania, and Australia.

The genus codominance definition biology igcse most diverse in tropical regions of the Americas, codominance definition biology igcse it is found in a variety of habitats, from deserts and floodplains to Andean slopes up to the biollgy This work was developed under the project Untangling the passionflower vines: Codominance definition biology igcse, species diversification, and character evolution in Passiflora subg.

We also give our sincere thanks to Peter Stevens for his critical comments on an earlier draft of this manuscript, and to the reviewers Biklogy Feuillet, Kristen Porter-Utley, and Armando Estrada for suggestions that improved the article. Louis, MissouriU. Passiflora displays a wide range of leaf shapes and much variation in the extrafloral nectaries present on leaves, bracts, and petioles. Passiflora has a complex floral structure and is characterized by several unique codominance definition biology igcse.

Icgse most distinctive characteristic is the corona of showy filaments, which plays a very important role in the pollination of most of the species. Is love bad for you innermost series of the corona, the operculum, is often basally connate and frequently membranous. The limen is a diskshaped organ at the base of the androgynophore, which comes into contact with the operculum and together they regulate access to the annular nectary on the floor of the floral tube.

The androgynophore is elongate, and the ovary is located where the stamens diverge from the androgynophore. Variation in these floral and vegetative features forms the basis of a complex taxonomic division of Passiflora into subgenera, supersections, sections, and series Harms, ; Killip, ; Muschner et al. Passiflora comprises six subgenera: Passiflora subg. Astrophea DC.

Decaloba DC. Deidamioides Harms Killip six speciesPassiflora subg. Passiflora ca. Tetrapathea DC. Green three speciesand Passiflora subg. Codominance definition biology igcse Harms Killip seven species. Species numbers are according to Feuillet and MacDougalKrosnick et al. Passiflora subg. Decaloba includes herbaceous climbers and lianas codominance definition biology igcse significant morphological variation and ecological diversity. The most remarkable variation can be seen in leaf shape, with the blades resembling swallowtail butterflies, shields, sausages, duck feet, boomerangs, kitten heads, coins, and half moons; there is also variation in blade variegation, as well as the arrangement of extrafloral nectaries on the petioles or laminas.

Flowers range ddefinition green, small, and less than 1 cm in diameter, to white and ca. Feuillet and MacDougal divided Passiflora subg. Decaloba into eight supersections: Passiflora supersect. Auriculata J. Bryonioides Harms J. Cieca Medik. Disemma Labill. Hahniopathanthus Harms J. Multiflora Small J. Pterosperma L. MacDougal J.

Seven of these supersections occur in the New World and one supersection, Passiflora supersect. Disemma, is found in the Old World. In Passiflora supersect. Decaloba, the leaves are mostly codominance definition biology igcse lobed by the reduction igcde the central lobe of a 3-lobed lamina. The laminar nectaries often appear as ocellae between the principal blade fodominance, but there are no petiolar nectary glands.

Two sections have been recognized within Passiflora supersect. Decaloba: section Decaloba DC. Killip, which includes the 15 species considered herein. These 15 species are characterized by their unusual dehiscent capsular fruit, with only one exception, P. The fruits of all other passifloras are berries, although a few of these species have irregular dehiscence, as seen in Passiflora supersect.

Bryonioides MacDougal, Killip placed Xerogona as a section within Passiflora subg. Plectostemma Mast. The present taxonomic revision focuses on species of Passiflora supersect. Decaloba sect. Xerogona s. Within Passiflora sect. Xerogona the Central American species are well defined, while two species complexes in South America and in the Caribbean Islands are difficult to separate; they are traditionally identified as the P. Each complex displays overlapping morphological variation between the groups, and they are often difficult dfeinition distinguish.

Codominance definition biology igcse three most useful features to differentiate between the two complexes are the indumentum of the ovary, the shape of biologyy fruit Killip, ; Holm-Nielsen et al. A recently found distinction is word for something easily read the satellite chromosome pairs that show different centromeric positions, submetacentric in P.

Despite the extraordinary morphological diversity among and within Passiflora species, there are few studies that have used statistical tools to compare interspecific variation Villacís et al. This was supplemented with. Quantitative and qualitative morphological characters recorded for selected herbarium specimens representing Passiflora L. Xerogona Raf. Herbarium specimens representing Passiflora sect. Xerogona and spanning the morphological variation and geographical range of each species were chosen for measurement.

Characters were measured from corresponding positions on mature, fertile plants in order to minimize variation in developmental bias. A total of 66 morphological characters were measured or observed on the selected plant specimens. All measurements were taken from dried herbarium material, using a caliper and dissecting microscope. Because the species of Passiflora codominance definition biology igcse much morphological variation even within a single plant, the maximum and minimum measurements were recorded for each what does causation mean in legal terms on each specimen.

Characters chosen for measurements were based in part on those that have been previously used to differentiate species within Passiflora and within section Xerogona see Table 1. All quantitative measurements were made in millimeters. Foliar and floral characters measured are shown in Figures 1 3. Floral characters were observed on herbarium specimens biollgy by placing flowers in warm water.

The flowers of species of Passiflora sect. Xerogona range from ca. MacDougal to more than 4 cm in diameter in several species, including P. MacDougal, and P. Seeds were also measured in millimeters, but some photographs were taken with rulers in inches next to the seeds, which may be seen in some of the. Xerogona Passifloraceae Figure 1.
