“…The genus comprises trees and rarely shrubs and is usually distinguished from other genera of the Lauraceae by the following characteristics: paniculate or racemose inflorescences that are not strictly cymose at the terminal division, bisexual and trimerous flowers with six equal to subequal tepals, six to nine fertile stamens representing the outer two or three whorls, two-celled anthers, and fruits lacking cupules. It is placed in the tribe Cryptocaryeae Nees together with other core genera such as Cryptocarya R.Br., Endiandra R.Br., and Potameia Thouars based on wood and bark anatomy and inflorescence structure (Van der Werff & Richter 1996). This classification is also supported by a molecular study (Chanderbali et al 2001).…”

SUMMARYA revision of Beilschmiedia Nees (Lauraceae) in Borneo is given. Descriptions, distribution maps, illustrations of leaves, terminal buds, and flowers, and a key to the species are provided. Twenty-six species were recognized, including one newly described species. The new species is distinguished from the other Beilschmiedia species of Borneo in having pubescent anther apices. Beilschmiedia reticulata was excluded from the revision as an imperfectly known species because of a lack of flowering specimens. Beilschmiedia eusideroxylocarpa was also excluded because it had only six stamens representing the second and third whorls, which is characteristic for the genus Endiandra.

Phylogeny and biogeography of Sassafras (Lauraceae) disjunct between eastern Asia and eastern North America

Abstract. Sassafras (Lauraceae) consists of three species disjunct between eastern Asia (S. tzumu and S. randaiense) and eastern North America (S. albidum). Phylogenetic analysis based on sequences of nuclear ribosomal ITS and three chloroplast noncoding regions (rpl16, trnL-F, and psbA-trnH) showed that Sassafras is monophyletic and that the eastern North American S. albidum is sister to the clade of its two eastern Asian counterparts. Their intercontinental divergence was estimated to be 13.80 ± 2.29)16.69 ± 2.52 million years ago (mya) using the penalized likelihood method with the ITS and three chloroplast markers. Biogeographic analyses combined with fossil evidence suggest that Sassafras has a relict distribution in the Northern Hemisphere without a Gondwanan link. The divergence time of the two eastern Asian species (the continental Chinese Sassafras tzumu and S. randaiense endemic to Taiwan) is estimated to be 0.61 ± 0.75)2.23 ± 0.76 mya. Sassafras randaiense from Taiwan was most likely derived from an ancestor from continental China.

“…As with stamen number, most genera have a constant number of cells per anther, but variation does occur in some ( Van der Werff & Richter 1996). All genera in Table 1 have 2-celled anthers, which are either introrse or extrorse.…”

ABSTRACT. An account of the genus Hexapora (Lauraceae) is presented. It comprises morphological descriptions of the genus and species, a provisional IUCN conservation assessment, ecological information and taxonomic notes. The morphology of the genus is compared to that of a number of possible close relatives, leading to the conclusion that it most likely belongs within the Beilschmiedia clade, and is likely closely related to Sinopora.
