“…Anatomical characteristics of the leaf petiole are considered to be useful in angiosperm (Howard, 1979; Hussin et al ., 2000) and fern (White, 1974; Lin & DeVol, 1977) systematics. Especially in ferns, the number of vascular strands and the arrangement and configuration of xylem elements in each leaf trace have been considered to be informative characters (Ogura, 1972; Lin & DeVol, 1977, 1978).…”

In ferns, leaf traces in the petioles are sometimes surrounded by a circumendodermal band (CB), a cell layer of varying structure and arrangement. We studied the CB of 89 fern species from 53 genera and 28 families, and its correlation with leaf trace configuration, leaf dissection and life form, to explore its anatomical diversity, possible origin and suitability for fern systematics. The cells of the CB always contain tannins in their lumina and their walls, but lack lignin and suberin. Cell wall thickness varies among species and may prove to be useful for fern systematics. The occurrence of the CB correlates with a larger number of vascular strands in the leaf trace and a lower degree of leaf dissection, but not with life form. Cystopteridaceae is the earliest branching family with a CB. The exclusive presence of the CB in nine of the most derived fern families supports the hypothesis of a single origin before the divergence of the two major clades of eupolypods. The discontinuity or absence of the CB in some species of derived families (e.g. Polypodiaceae, subfamily Polypodioideae) is interpreted as a secondary loss. Possible functions of the CB are discussed. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 596–610.

Chemical and genetic diversity of ginger germplasm (Zingiber officinale) Plant genetic resources exhibit a true and potential value for agriculture due to their importance in breeding and conservation programs. This study aimed to characterize the genetic and chemistry diversity of ginger germplasm of Genetics Department of the ESALQ/USP, through 18 phenotypic descriptors, 13 AFLP markers combinations and chemical composition analysis of essential oil. The germplasm was combined by accessions coming from diferent Brazilian states, along with some accessions introduced from Colombia. During the collection, 34 farmers were interviewed in three states: São Paulo (SP), Espírito Santo (ES) and Paraná (PR). Ginger is mainly cultivated by small farmers whose main income source is agriculture. In the chemical composition analysis, a total of 61 compounds were identified. The accessions presented chemical variability according to the analysis of variance. The essential oil was rich in monoterpenes (82.35%), being the geranial (20.41%) and the neral (13.36%), both referred to as citral, the most abundant compounds. The α-zingiberene, 1,8-cineole, linalool and β-phellandrene compounds were relevant in the chemical diversity analysis of the accessions, while the dendrogram based on the complete linkage method (LC-VD) classified the germplasm into two groups: landraces and cultivars accessions. In the agromorphologic characterization, qualitative traits showed little variation, while moderate to low variability was observed for quantitative traits, although some divergent accessions were identified. The principal component analysis explained 82% of the total variation in the first three components, wherein the accessions distribution on the scatter plot was consistent with the groups formed by the Tocher method, with the Gen-18, Gen-24, Gen-65 and Gen-42 accessions as the most divergent ones from the phenotypically germplasm. In the molecular characterization, 13 AFLP markers combinations generated an average of 113.5 polymorphic loci, with a ratio of 96.85% of polymorphism in the overall collection. Estimates of Nei genetic diversity (H j), Shannon index (I) and alleles effective number (n e) were higher in Colombian accessions (0.501; 0.396 and 1.508, respectively). The AMOVA showed that most of the variation (63%) occurs between the two countries and the F ST =0.153 index suportted this result, indicating high genetic differentiation between Brazilian and Colombian accessions. The groupings provided by Structure and the dendrogram based on Jaccard coefficient complement were consistent with each other and showed that Brazilian accessions are genetically similar. In general, there is no influence of the accesses geographic origin in the chemical, phenotypic and molecular grouping pattern. The introduction of new genetic materials in Brazil, will certainly contribute to a broader genetic basis of this species.

2005. Comparative leaf anatomy of AIpinia species (Zingiberaceae) in Malaysia. -Nord. J. Bot. 23: 463-483. Copenhagen. ISSN 0107-055X.The leaf anatomy of 22 Alpinia species from the Malay Peninsular was investigated. Results show that a combination of characters such as outlines of midribs, petioles, leaf margins and their relative sizes in transverse sections as well as the presence of hypodermal fibres in the lamina, midribs and petioles can be used in the identification of species. All four species of subsection AIIughas possess similar characters such as the presence of abaxial and adaxial fibres in the midrib and petioles and the absence of hypodermis in the lamina while the reverse is true for all species of subsection Catimbium. AIpinia conchigera and A. galanga appear to be closely related while A. oxymitra is distinct from all the species studied.
