    Photooxidation and Intramolecular Reaction of the Anthryl Moiety in [60]Fullerene Derivatives (2000)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 2000 (2000), S. 1647-1651 
    Details
    ISSN: 1434-193X

    Topics: Chemistry and Pharmacology
    Notes: ---Anthracene groups have been linked to [60]fullerene by the [3+2] cycloaddition of the corresponding nitrile oxides or by esterification with a [60]fullerenol. The anthryl groups of the fullerene derivatives 3, 7, and 10 react readily with singlet oxygen to form the 9,10-epidioxides 4, 8, and 12 under photooxidation. The anthryl moiety of the fullerenol ester 10 also reacts with the fullerene skeleton to form the stable intramolecular Diels-Alder adduct 11.

    Contributions to the morphology, anatomy, and karyology ofRhabdodendron, and a reconsideration of the systematic position of theRhabdodendronaceae (1976)
    Springer
    Plant systematics and evolution 125 (1976), S. 195-222 
    Details
    ISSN: 1615-6110
    Keywords: Rhabdodendronaceae ; Rhabdodendron ; Leaf ; inflorescence and floral morphology ; leaf and node anatomy ; chromosome number ; Systematic affinities
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Rhabdodendron macrophyllum (Spruce ex Benth.)Huber andR. amazonicum (Spruce exBenth.)Huber differ in several anatomical and morphological characters (secretory cavities, hypoderm, peltate hairs, internodal region and petiole). A position of the monotypicRhabdodendronaceae in theCentrospermae as recently suggested is hardly supported: Peltate hairs, lysigenous secretory cavities and spicular cells in the leaves, multilacunar nodes, chromosome number (R. macrophyllum: n = 10; first count for the genus resp. family), ± simultaneous (or slightly centripetal) development of the androeceum, anacrostyly and two ovules in the unicarpellate gynoeceum, apparent disc, monotelic racemes, and data available from literature (pollen, sieve tube plastids) clearly indicate a close affinity toRutaceae, and even make the family rank ofRhabdodendron questionable.

    Two new species ofPhyllagathis related toP. tuberculata (Melastomataceae) from Peninsular Malaysia (1987)
    Springer
    Plant systematics and evolution 157 (1987), S. 187-199 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Melastomataceae ; Phyllagathis ; Taxonomy ; inflorescence and floral morphology ; Flora of Malesia and Malaysia
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Phyllagathis tuberculata King and two closely allied new species,P. magnifica A. Weber andP. stonei A. Weber, are described and illustrated. Within the genus, these species form a distinct and isolated group which is restricted to Peninsular Malaysia.P. tuberculata occurs in Perak (probably confined to G. Bujang Melaka),P. magnifica andP. stonei are found in the mountains on the Pahang/Selangor border (Genting Highlands, Gombak valley). The distinctive characters of the three species are listed and some general information relating to inflorescence morphology, tubercle anatomy, fruit structure and seed dispersal is provided.
