    The status of Cecropia (Urticaceae) introductions in Malesia: addressing the confusion (2012)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 57 no. 2, pp. 136-142
    Details
    Publication Date: 2024-01-12
    Description: As part of the great global movement of plants in the 18th and 19th centuries, many valuable and commercial plants were sent from the Neotropics to Europe as seeds or as live specimens. Cecropia (Urticaceae) was in cultivation in England in 1789, yet species delimitation was not well-understood until much later, long after subsequent introductions to other tropical regions where alien populations are now invasive. The earliest record of Cecropia being cultivated in Malesia is based on material of C. peltata thought to have been sent from the Royal Botanic Gardens Kew to \xe2\x80\x99s Lands Plantentuin (Buitenzorg) in Jawa, Indonesia, sometime between 1862 and early 1868. In 1902, C. peltata was first cultivated in the botanical gardens of Singapore and introduced to Peninsular Malaysia in 1954. The source of these latter introductions is uncertain. Many researchers have assumed that C. peltata is the only species of Cecropia introduced in Indonesia, Malaysia and Singapore. We confirm that C. peltata is naturalised in Singapore and is invasive on the island of Jawa, Indonesia, and in Peninsular Malaysia.\nHowever, a second introduced species, C. pachystachya, has also been discovered as invasive in both Jawa and Singapore. There is no evidence for the third previously introduced species, C. palmata, being extant in Malesia.

    A taxonomic revision of Geniostoma subg. Geniostoma (Loganiaceae) (1980)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 26 no. 2, pp. 245-364
    Details
    Publication Date: 2024-01-12
    Description: A taxonomic revision of Geniostoma subg. Geniostoma is presented. The relationship between Labordia and Geniostoma is discussed; Labordia being regarded as a subgenus of Geniostoma. General chapters on morphology, anatomy, seed dispersal, chromosome numbers, inter- and intraspecific relationships, geography, and evolution precede the systematic treatment. Two sections are recognised in the subgenus Geniostoma. Section Macrostipulare is described as new. Two sections (sect. Labordia and sect. Darbolia) are recognised in the subgenus Labordia. Section Rabdolia is reduced to the synonymy of section Labordia. Twenty-three species of Geniostoma subgenus Geniostoma are recognised, of which five are described for the first time. The new species are G. grandifolium, G. leenhoutsii, G. mooreanum, G. trichostylum, and G. umbellatum. Fourteen varieties of G. rupestre are recognised, of which var. rouffaeranum and var. solomonense are described as new.\nA general key to the species plus two regional keys, one for Papuasia and one for New Caledonia, and keys to the varieties are provided. All recognised taxa are provided with full descriptions, distribution, ecological and other relevant notes. Most species and varieties are illustrated. A full enumeration of collections examined is provided.

    Usefulness of morphological characters for infrageneric classi\xef\xac\x81cation\nof Elatostema (Urticaceae) (2009)
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 54 no. 1/3, pp. 181-191

    Publication Date: 2024-01-12
    Description: In 1896, Hans Hallier was the first author to reduce the two genera Pellionia and Procris to subgeneric status within the genus Elatostema (Urticaceae). In 1935 and 1936, Hilde Schr\xc3\xb6ter and Hubert Winkler proposed the following four subgenera: subg. Elatostema, subg. Elatostematoides, subg. Pellionia and subg. Weddellia, while maintaining Procris as a distinct genus. More recently, Wang (1980a) rejected Schr\xc3\xb6ter and Winkler\xe2\x80\x99s subgeneric classification of Elatostema and proposed a sectional and serial infrageneric classification of recognising as sections Androsyce, Elatostema, Laevisperma, Pellionioides and Weddellia (as \xe2\x80\x98Weddelia\xe2\x80\x99). He maintained both Pellionia and Procris as distinct genera. All previous researchers of Elatostema and related taxa primarily based their classifications on the morphology of leaves, stipules, inflorescence and receptacle. Our analysis, based on similar morphological characters, does not support the previous infrageneric classifications. Procris forms a monophyletic clade, nested within a clade consisting of several species of Elatostema subg. Pellionia and one of subg. Elatostematoides. Elatostema auriculatifolium (subgeneric classification unclear) is also included within this clade. This clade is sister to the E. latifolium\xe2\x80\x93E. tsoongii pair of species (also subg. Pellionia), subg. Elatostema (the remaining species of this subgenus), species of subg. Weddellia and E. rostratum (subg. Elatostematoides).\nElatostema subg. Weddellia is paraphyletic within subg. Elatostema. The recognition of Elatostematoides, Pellionia and Procris as distinct genera is not supported.

    A tribute to Ted Henty (1915-2002) (2002)
    In:  Flora Malesiana Bulletin vol. 13 no. 2, pp. 161-168
    Details
    Publication Date: 2024-01-12
    Description: Ted Henty, noted for his work in the Papua New Guinea National Herbarium (LAE), died aged 86 at East Keilor, near Melbourne on 23 February 2002 after an illness of 6-8 months. Those dealing with New Guinea plants will know of his extensive collections in the NGF and subsequent LAE series from all over the country. The new Composite genus Piora from the alpine grasslands on Mt Piora was just one discovery made in 1963 with S. Carlquist.\nThose who knew Ted will consider him a fine field botanist, arguably one of the finest that has worked in Papua New Guinea. Not one to involve himself with revisionary studies, he was more concerned with the dissemination of floristic, practical and economic knowledge to the wider user (although with the intensive exploration of Papua New Guinea the opportunities were abundant, Ted never described a new taxon). [The only new combination I know of was made inadvertently: Digitaria microbachne Henrard var. calliblepharata (Henrard) Henrard ex Henty, Bot. Bull., Lae 1 (1969) 77. Ed.] He preferred to call himself a \xe2\x80\x98didiman\xe2\x80\x99 (agronomist). He specialised in grasses and weeds, logical as his home life surrounded the farming of cattle and growing tropical fruit up the Markham Valley from Lae. Nevertheless, his knowledge of the broader flora of Papua New Guinea was vast.

    Notes: [Auszug] SIR-Clifford, Rogers and Dettmann have exaggerated the problems faced by taxonomic institutes and have misunder-stood the role of herbaria. They suggest a solution that displays ignorance and a surprising lack of understanding in profes-sional biologists. The worry is that their solution may ...
