    New taxa of Pandanus (Pandanaceae) from Malesia and Papuasia (1987)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.32 (1987) nr.2 p.427
    Details
    Publication Date: 2015-03-06
    Description: Monographic studies in Pandanaceae continue to yield previously unrecognized taxa both at specific and higher ranks. In Pandanus, with the increase of knowledge of staminate structures becoming available through better collections and more critical observations, use of staminate characters integrated with previously known data is providing important new insights into infrageneric taxa and their affinities, as well as completing the fundamental descriptions at species rank important for both systematic and ecological studies. In the results reported here two new species, Pandanus calvus and P. kosteri, and two new sections, Hastatistigma (based on P. vinaceus) and Macrokurzia (based on P. daymanensis) are proposed. Two species previously known only from pistillate materials, P. cernuifolius and P. irregularis, are clarified by description of staminate specimens, while in the case of P. copelandii, a previously unrecognized staminate feature is described. Field data for the inadequately known species P. leptocarpus are provided, and the first illustrations of the type specimen (staminate) of P. houlletii are provided. These taxa are discussed under the subgenera to which they are referred in the synopsis (Stone, 1974).

    Materials for a monograph of Freycinetia Gaud. IV. Subdivision of the genus, with fifteen new sections (1968)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 16 no. 2, pp. 361-374
    Details
    Publication Date: 2024-01-12
    Description: The previous subdivision of Freycinetia Gaud. ( Pandanaceae) into two parts, Sect. Oligostigma Warb. and Sect. Pleiostigma Warb. (now called Sect. Freycinetia) has because of numerous additions to our knowledge of the genus become obsolete. Fifteen new sections are proposed, based on natural species-groups, and the original two sections are restricted and redefined. Species not yet adequately known may be termed Freycinetiae imperfectae, when only staminate specimens are known, or incertae sedis. A map showing the distribution of the genus is included.

    The New Guinea species of Pandanus section Maysops St. John (Pandanaceae) (1992)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 37 no. 1, pp. 31-61
    Details
    Publication Date: 2024-01-12
    Description: Species of Pandanus belonging to section Maysops St. John [this section is presently classified under subgenus Lophostigma (Brongn.) Stone], about 16 in all, occur in New Guinea, the adjacent Moluccas, the Bismarck Archipelago, the Solomon Islands, and Northern Queensland, Australia. The majority (11) of the species are found in, and mostly limited to, New Guinea. Here these 11 species are reviewed, a key for identification is presented, and information on synonymous names, distribution, and certain critical aspects of morphology is included. In an appendix, the remaining species assigned to section Maysops are briefly listed. There are probably a few undescribed species.

    Rediscovery of Thismia clavigera (Becc.) F. v. M. (Burmanniaceae) (1980)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 26 no. 2, pp. 419-425
    Details
    Publication Date: 2024-01-12
    Description: The Burmanniaceous saprophyte originally described as Geomitra clavigera Becc., and known only from the type collection made in Sarawak in 1865, was rediscovered in Pulau Langkawi, Kedah, Malaysia, in November 1979. This second collection appears to match the original in all important respects, and permits a fuller description of the underground parts and seeds, and allows a fuller account of the staminal ring structure. A review of the generic characters indicates that the genus Geomitra should, however, be subsumed within Thismia Griff., and the species therefore is to be called Thismia clavigera (Becc.) F.v.M. Another recent, third, collection of this species, from North Sumatra, is discussed in an addendum.

    Bibliographic correction in Thismia (Burmanniaceae) (1981)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 27 no. 2, pp. 481-481
    Details
    Publication Date: 2024-01-12
    Description: In my paper \xe2\x80\x98Rediscovery of Thismia clavigera (Becc.) F. v. M. (Burmanniaceae)\xe2\x80\x99 in Blumea 26 (1980) three combinations made by F. J. H. von Mueller in the genus Thismia were mentioned, viz. T. clandestina (Bl.) F. v. M., T. clavigera (Becc.) F. v. M., and T. episcopalis (Becc.) F. v. M. These combinations were overlooked inadvertently in the compilation of T. B. Muir (1979), \xe2\x80\x98An index to the new taxa, new combinations, and new names published by Ferdinand J. H. Mueller\xe2\x80\x99 in Muelleria 4 (2): 123-168. The bibliographic citations for these three combinations have been corrected, thanks to a letter from Mrs. D. Sinkora of the Royal Botanic Gardens and National Herbarium of Victoria, Australia, and are given here: Thismia clandestina (Blume) F. v. Muell., Pap. & Proc. Roy. Soc. Tasmania, 1890: 235. (1891). Thismia clavigera (Beccari) F. v. Muell., Pap. & Proc. Roy. Soc. Tasmania, 1890: 235. (1891). Thismia episcopalis (Beccari) F. v. Muell., Pap. & Proc. Roy. Soc. Tasmania, 1890: 235. (1891).\nAdditionally it should be noted that the citation of Victorian Naturalist (Vict. Nat.) vol. 6, should be omitted. The reference should have been to the Papers & Proceedings of the Royal Society of Tasmania. Although dated 1890, the volume was actually published in 1891. All three combinations, therefore, were made in the same publication in the same year.
