The Gesneriaceae of Sulawesi I: an Introduction
EDINBURGH JOURNAL OF BOTANY 60 (3): 299–304 (2004) 299 DOI: 10.10M/S0960428603000258 THE GESNERIACEAE OF SULAWESI I: AN INTRODUCTION M. MENDUM*† & H. J. ATKINS* Sulawesi (Celebes) is the largest island in the biogeographic region of Wallacea. The Gesneriaceae of the island are represented by 11 genera, some of which show a very high degree of endemism. Knowledge of the origin and affinities of the flora of this island is important for an understanding of the biogeography of the area. The Gesneriaceae promise to be excellent models for phytogeographic analysis, but before this, basic taxonomic studies must be carried out. A list of the currently known genera and species is provided, and descriptions of new taxa will be published over the coming months. Keywords. Biogeography, Gesneriaceae, Indonesia, Sulawesi, Wallacea. The islands of SE Asia comprise one of the most geologically complex regions in the world (Audley-Charles, 1981; Hall, 1996, 1998), at the meeting point of three major tectonic plates. Its turbulent geological history and exceptionally high levels of biological endemism make this region of prime interest to biogeographers. Wallace’s line, one of the most important biogeographic boundaries in the world, bisects the archipelago, and was originally thought to mark the meeting point of the Oriental and Australasian fauna and flora. Since Wallace first drew his line in 1863, many others have been drawn, reflecting different hypotheses based on the distribu- tion patterns of different taxa (summarized in Scrivener et al., 1943; Simpson, 1977). The difficulty of agreeing on a single line eventually resulted in the identification of a zone of transition in the centre of Malesia (Dickerson, 1928). -
Litter Production and Decomposition in Cacao (Theobroma Cacao) and Kolanut (Cola Nitida) Plantations
ECOTROPICA 17: 79–90, 2011 © Society for Tropical Ecology LITTER PRODUCTION AND DECOMPOSITION IN CACAO (THEOBROMA CACAO) AND KOLANUT (COLA NITIDA) PLANTATIONS Joseph Ikechukwu Muoghalu & Anthony Ifechukwude Odiwe Department of Botany, Obafemi Awolowo University, O.A.U. P.O. Box 1992, Ile-Ife, Nigeria Abstract. Litter production and decomposition were studied at monthly intervals for two years in Cola nitida and Theo- broma cacao plantations at Ile-Ife, Nigeria. Three plantations of each economic tree crop were used for the study. Mean annual litter fall was 4.73±0.30 t ha-1 yr-1 (total): 3.13±0.16 t ha-1 yr-1 (leaf), 0.98±0.05 t ha-1 yr-1(wood), 0.46±0.12 t ha-1 yr-1 (reproductive: fruits and seeds), 0.17±0.03 t ha-1 yr-1 (finest litter) in T. cacao plantations and 7.34±0.64(total): 4.39±0.38 (leaf), 1.57±0.17 (wood), 1.16±0.13 (reproductive) and 0.22±0.01 (finest litter or trash) in C. nitida plantations. The annual mean litter standing crop was 7.22±0.26 t ha-1 yr-1 in T. cacao and 5.74±0.54 t ha-1 yr-1 in C. nitida plantations. Cola nitida leaf litter had higher decomposition rate quotient (2.00) than T. cacao leaf litter (1.03). Higher quantities of calcium, magnesium, potassium, nitrogen, phosphorus, sulfur, managenese, iron, zinc and copper were deposited on C. nitida than on T. cacao plantations. The low litter decomposition rates in these plantations implies accumulation of litter on the floor of these plantations especially T. -

Phylogeny of Southern African and Australasian Wahlenbergioids (Campanulaceae) based on ITS and trnL-F sequence data: implications for a reclassification Christopher N. Cupido , Jessica M. Prebble , and William M. M. Eddie Abstract The Campanulaceae: Wahlenbergioideae currently comprises 15 genera, one of which, Wahlenbergia, is widespread over the southern continents. Southern Africa is the region with maximum wahlenbergioid diversity with 12 genera and approximately 252 species. A second center is Australasia with 38 Wahlenbergia species. This study used a broad sample of wahlenbergioid diversity from South Africa, Australia, and New Zealand to reconstruct a phylogeny based on chloroplast trnL-F and nuclear ITS sequences. Data were analyzed separately and in combination using parsimony and Bayesian methods. The results suggest that for the wahlenbergioids to be monophyletic Wahlenbergia hederacea has to be excluded and that none of the South African, Australian or New Zealand lineages are strictly monophyletic. There are five species assemblages that are in some disagreement with current classification in the family. Wahlenbergia, Prismatocarpus and Roella are shown to be non-monophyletic and implications for a reclassification are presented. Careful consideration of morphological characters is suggested before the adjustment of generic circumscriptions can be accomplished. Recent family-wide molecular phylogenetic studies have supported the view that the Campanulaceae s.s. -

Cycad Leaf Physiology Research Needed 1 August 2017
Cycad leaf physiology research needed 1 August 2017 they contain close to 400 described species. Guiding principles are needed to improve the representation and relevance of these plants in contemporary research agendas. According to Marler, the addition of more descriptive research targeting cycad species is welcomed regardless of the approach. But the adherence to protocols that ensure species relevance would improve the outcomes. Since forest canopy traits define sunfleck qualities, the experimental protocols for studying sunfleck use by newly studied species should be defined from the natural habitats of each species. Moreover, the behavior of cultivated plants often differs from that Healthy juvenile plants of the endangered Cycas of plants in natural settings, and moving from the micronesica thrive in a deep understory habitat where current level of minimal knowledge to a level of they effectively utilize infrequent sunflecks. Credit: adequate knowledge may be reached most rapidly Thomas Marler by studying these plants within their native range rather than in botanic gardens. A phenomenon called context dependency is also pertinent to the needed expansion of cycad research. Do The living cycad species are among the world's environmental factors such as drought influence most threatened plant groups, but are also among how a cycad plant capitalizes on the ephemeral the world's least studied plant groups. The need for access to sunflecks? a greater understanding of basic physiology of cycads has been discussed for decades, yet to Attempts to link phylogenetic subsets of plants date the needed research is lacking. more closely to the broader global research agenda need to be accurate. -

Department of Biological Sciences, University of Agriculture, Abeokuta, Ogun State, Nigeria *Correspondence author: [email protected] ABSTRACT Foliar epidermal studies were conducted on ten species in the family Sterculiaceae in search of stable taxonomic characters that could be employed in order contribute to their classification and identification. In spite of the remarkable morphological differences, the results indicated that the species are relatively uniform in their quantitative macromorphological characters except for the leaf shape and base which varied from elliptic, lanceolate to palmate and leaf base from cordate, obtuse to cunneate. The epidermal characters such as number of cells, anticlinal wall pattern, cell wall thickness and the stomata size varied among the species. The epidermal cells varied from polygonal to irregular while the anticlinal walls varied from straight to straight\curve and slightly curved. All the species except Cola nitida (Vent) Schott, Malachanta alnifolia (Bak) Pierre, Mansonia altissima (A.Chev) R.Capuron, Theobroma cacao Linn and Waltheria indica Linn are amphistomatic. Stomata types included anisocytic in T. cacao, laterocytic in C. hispida, anomocytic in C. millenni Schum, Staurocytic in C. nitida and paracytic in W. indica, M. altissima and Malacantha alnifolia.

They are exclusively distributed in undisturbed habitats, and some have high ornamental value. The species are morphologically diverse, but face a problem of taxonomic delineation, which is further complicated by the presence of putative hybrids. -

Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear. -
