Chemogeographical evolution of terpenoids in icacinaceae

Phytochemistry, 1991
Abstract Chemical evolution in the Icacinaceae, postulated to involve oxidative sequences within monoterpenoids (iridoids, complex seco-iridoid alkaloids), sesquiterpenoids (emmotins) and diterpenoids (icaceines and humiriantholides), is accompanied by spatial radiation of genera from Melanesia in a western direction along the tropical belt to ...

Multiple origin of the tropical forest tree family Icacinaceae

American Journal of Botany, 2001
Analyses of DNA sequences from four genes (ndhF, rbcL, atpB, and 18S rDNA) and morphological data show that the members of the tropical forest tree family Icacinaceae do not have a common origin. All of the genera earlier placed in Icacinaceae are euasterids but placed in the following three different orders: Garryales, Aquifoliales, and Apiales ...

Bark Structure of the Southern African Icacinaceae

IAWA Journal, 1994
A description of the bark structure of southern African species of Apodytes and Cassinopsis is presented for the first time. Bark anatomy was found useful in distinguishing between species, especially in the genus Apodytes. Fibres, associated with sclereids, are found exclusively in Apodytes spec. nov. B, whereas A. dimidiata subsp.

Icacinaceae fossil provides evidence for a Cretaceous origin of the lamiids

Nature Plants, 2022
Today the asterids comprise over 80,000 species of flowering plants; however, relatively little is known about the timing of their early diversification. This is particularly true for the diverse lamiid clade, which comprises half of asterid diversity.

Anatomical studies in West Malaysian Icacinaceae

Australian Systematic Botany, 1999
On the basis of a comparative anatomical study of the leaf lamina and petiole of six genera of Icacinaceae in West Malaysia, these genera can be classified into four closely knit groups by virtue of their many shared characters: Group I comprises Cantleya , Gomphandra and Stemonurus whereas Groups II and III are made up of Gonocaryum and Sarcostigma ...

A revision of the genus Medusanthera (Stemonuraceae, Icacinaceae s.l.)

Kew Bulletin, 2011
The genus Medusanthera (Stemonuraceae, Icacinaceae s.l.) is revised; eight species are recognised. Three new species are described and illustrated: Medusanthera megistocarpa Utteridge from New Guinea, M. howardii Utteridge from Fiji, and M. malayana Utteridge from Peninsular Malaysia. A key to the genus is given, and descriptions, conservation ratings,

Three new species and a new name in Southeast Asian Gomphandra (Stemonuraceae / Icacinaceae s.l.)

Blumea: Journal of Plant Taxonomy and Plant Geography, 2010
Three new species of Gomphandra (Stemonuraceae / Icacinaceae s.l.) are described from Malesia, and a new name is proposed for a misidentified species. Gomphandra palustris is known from peat swamp forests in Borneo, Sarawak, G.
