Última Redefinition of Zehneria and four new related genera (Cucurbitaceae), with an enumeration of the Australasian and Pacific species Naturalis Wilde, W.J.J.O. de; Duyfjes, B.E.E.. The genus Zehneria Endl. is split into 5 genera, of which 4 are new: Indomelothria, Neoachmandra, Scopella, and Urceodiscus. Apart from several new combinations and taxa of subspecific rank, the following species are described as new: I. chlorocarpa, N. backeri, N. lancifolia, N. macrantha, N. nesophila, N. platysperma, U. arfakensis, U. carrii, U. hippocrepicus, U. parviflora, U. scabridula, U. viridis, Z. elbertii, Z. erythrobacca, Z. immarginata, Z. neocaledonica, Z. pedicellata, Z. pisifera, Z. tahitensis, and Z. trullifolia. The New World genus Melothria was introduced in Asia where it is represented by one species, M. pendula L.

Ano: 2006 URL: http://www.repository.naturalis.nl/record/526004 Assessment of age and greenness of herbarium specimens as predictors for successful extraction and amplification of DNA Naturalis Erkens, R.H.J.; Cross, H.; Maas, J.W.; Hoenselaar, K.; Chatrou, L.W.. Age and the greenness of leaves have been frequently used as indicators for selecting herbarium specimens for molecular studies. Although plant DNA extraction and amplification have been common lab procedures for the past 20 years, no studies specifically investigated the success of these indicators. Here the predictive value of age and the greenness for extraction and amplification success is assessed, using a large number of herbarium specimens from different plant groups. The investigation of these indicators is important because herbarium material is a precious commodity, and is often the only remaining floral record of now extinct ecosystems. In cases where little leaf material is available, most researchers still attempt to extract DNA. This study...
