TLDR
The wood of 27 genera, 16 of which are in the core-Millettieae and the remaining 11 belong in 4 groups, mostly with closer affinities outside Millettieae s.str, is examined.Abstract:
The tribe Millettieae has traditionally included some 43 to 47 genera although more recent phylogenetic evidence has shown that a smaller core-Millettieae group of c. 23 genera may form part of a recircumscribed Millettieae sensu stricto. We have examined the wood of 27 genera, 16 of which are in the core-Millettieae and the remaining 11 belong in 4 groups, mostly with closer affinities outside Millettieae s.str. The wood anatomy of the various genera is nevertheless very uniform. Most genera are diffuse porous with no predominant vessel pattern. They have paratracheal parenchyma ranging from scanty through vasicentric, aliform and confluent, and often banded. Rays are mainly up to 5 cells wide. Axial parenchyma and rays are nearly always storied. The lianas Paraderris elliptica, Derris uliginosa, Ostryocarpus cf. riparius and Wisteria spp. have alternating bands of xylem and phloem, which are also found in some Dalbergieae. Even in the genera without such anomalous secondary growth there are many similarities between the wood of Millettieae and Dalbergieae. The wood of some genera in Sophoreae and Swartzieae is also compared. Our observations will be put in the context of recent cladistic analyses on both morphological and molecular data by other authors.read more

Historic fuel wood use in the Galápagos Islands: identification of charred remains

TL;DR: In this paper, a set of charcoal fragments from five historic campsite locations in the Galapagos Islands were identified and radiocarbon dated to investigate postulated early human presence in the archipelago, historic fuel wood collection patterns and the resultant impact on native vegetation.

Fuel economy, woodland management and adaptation strategies in a Classic Maya city: applying anthracology to urban settings in high biodiversity tropical forests
TL;DR: In this article, the domestic fuel economy at the lowland site of Naachtun, Guatemala, over 8 centuries (150-950 ce) was traced to discover its role in the development of society.

Phylogeny of palaeotropic Derris-like taxa (Fabaceae) based on chloroplast and nuclear DNA sequences shows reorganization of (infra)generic classifications is needed
TL;DR: This study shows that previous infrageneric classifications of Derris are incorrect, and the concept of the genus Derris s.s. should be reorganized with a new generic circumscription by including Paraderris but excluding Brachypterum.

Wood anatomy of the tribe Podalyrieae (Fabaceae, Papilionoideae): Diversity and evolutionary trends
A.V. Stepanova,A.V. Stepanova,Alexei A. Oskolski,Alexei A. Oskolski,Patricia M. Tilney,B.-E. Van Wyk +5 more
TL;DR: Comparisons of the main character state changes with the molecular phylogeny of the tribe show that the wood structure of trees probably represents the basic condition in the tribe; character states present in shrubs appear to have arisen a few times and very likely represent adaptations to seasonal water stress.
