Caryophyllales: a key group for understanding wood anatomy character states and their evolution

Wood and Stem Anatomy of Phytolaccoid and Rivinoid Phytolaccaceae (Caryophyllales): Ecology, Systematics, Nature of Successive Cambia

Quantitative and qualitative wood features are presented and analyzed for seven species of subfamily Rivinoideae and four of subfamily Phytolaccoideae. All species have nonbordered perforations plates, as elsewhere in suborder Phylocaccineae. Libriform fibers characterize both subfamilies, but vasicentric tracheids occur in two rivinoid species. Axial parenchyma is vasicentric scanty (apotrache...

Wood anatomy of Agdestis (Caryophyllales): systematic position and nature of successive cambia

Features in which Agdestis differs from Phytolaccaceae s. s. include presence of both libriform fibers and vasicentric tracheids (rather than one or the other); bands and strands of thin-walled apotracheal parenchyma (in addition to paratracheal scanty parenchyma}, and raylessness (also reported for Bougainvillea of Nyctaginaceae, a family close to Phytolaccaceae). Dimorphism in vessel diameter...

Further Concepts in Ecological Wood Anatomy, with Comments on Recent Work in Wood Anatomy and Evolution

Computer Character Sets: Their Evolution and Impact

This paper resulted from a joint presentation made by Mr John Clews of the Sesame Project and myself. Mr Clews covered the evolution and standards of the different character sets used on computers in the past and present times. He culminated in a description of the UNICODE character set, which should be the one that is universally adopted. This paper should be read in conjunction with that of M...
