Wood Anatomy of Polygonaceae: Analysis of a Family with Exceptional Wood Diversity
Botanical Journal of the Lirtneon Society. 2003. 141. 25—51. With 59 figures Wood anatomy of Polygonaceae: analysis of a family with exceptional wood diversity SHERWIN CARLQUIST FLS Santa Barbara Botanic Garden, 1212 Mission Canyon Road, Santa Barbara, CA 93105, USA Received May 2002; accepted for publication August 2002 Quantitative and qualitative data are presented for woods of 30 species of woody Polygonaceae. Wood features that ally Polx’gonaceae with Plumbaginaceae include nonbordered perforation plates, storeing in narrow vessels and axial parenchyma, septate or nucleate fibres, vasicentric parenchyma, pith bundles that undergo secondary growth, silica bodies, and ability to form successive cambia. These features are consistent with pairing of Plumbaginaceae and Polgonaceae as sister families. Wood features that ally Polygonaceae with Rhabdodendraceae include nonbor dered perforation plates, presence of vestured pits in vessels, presence of silica bodies and dark-staining compounds in ray cells, and ability to form successive cambia. Of the features listed above, nonbordered perforation plates and ability to form successive cambia may be symplesiomorphies basic to Caryophyllales sensu lato. The other features are more likely to be synapomorphies. Wood data thus support molecular cladograms that show the three families near the base of Caryophyllales si. Chambered crystals are common to three genera of the family and may indicate relationship. Ray histology suggests secondary woodiness in Antigonon, Atraphaxis, Bilderdyhia, Dedeckera, En ogonun-i, Hanfordia, Muehlenbechia, Polygonum, and Rumex. Other genera of the family show little or no evidence of secondary woodiness. Molecular data are needed to confirm this interpretation and to clarify the controversial sys tematic groupings within the family proposed by various authors. -
A Relict Species Restricted to a Quartzitic Mountain in Tropical America: an Example of Microrefugium?
Acta Botanica Brasilica 29(3): 299-309. 2015. doi: 10.1590/0102-33062014abb3731 A relict species restricted to a quartzitic mountain in tropical America: an example of microrefugium? Newton Pimentel de Ulhôa Barbosa1,2*, G. Wilson Fernandes1 and Arturo Sanchez-Azofeifa2 Received: August 29, 2014. Accepted: March 11, 2015 ABSTRACT We examined the distribution of Coccoloba cereifera, a tropical endemic species that occurs in a small area in the Espinhaço mountain range, southeastern Brazil. It is hypothesized that its narrow distribution is strongly related to the spatially scattered distribution of sandfields. However, this soil type extends far beyond the small region where C. cereifera is currently found, indicating that other factors might be involved in the distribution of this species. Coccoloba cereifera also displays all traits of a relict population in a microrefugium. As a result, we were encouraged to explore other factors potentially related to the distribution of the species. In an attempt to aid in the understanding of the processes and mechanisms that lead C. cereifera to present the narrow actual distribution, we applied two distribution modelling approaches to investigate the potential distribution of the species beyond the small known distribution area. The distribution seems to be strongly associated with sandy patches/grasslands formed among rocky outcrops and is limited by some topoclimatic and/or topographic features. Some of them related to the existence of a microrefugium, a fact also suggested by the pattern of distribution of the species in the past. From the management point of view, the existence of a microrefugium in this area calls for changes in conservation efforts and priorities. -
