The Species of Wurmbea
J. Adelaide Bot. Gard. 16: 33-53 (1995) THE SPECIES OFWURMBEA(LILIACEAE) IN SOUTH AUSTRALIA Robert J. Bates Cl- State Herbarium, Botanic Gardens, North Terrace, Adelaide, South Australia 5000 Abstract Nine species of Wunnbea Thunb. are recognised in South Australia. W. biglandulosa (R. Br.)Macfarlane, W. deserticola Macfarlane and W. sinora Macfarlane are recorded for the first time; Wurmbea biglandulosa ssp. flindersica, W. centralis ssp. australis, W. decumbens, W. dioica ssp. citrina, W. dioica ssp. lacunaria, W. latifolia ssp. vanessae and W. stellata are described. A key, together with notes on each species is provided. Macfarlane (1980) revised the genus for Australia. He placed Anguillaria R. Br. under Wurmbea and recognised W. dioica (R. Br.)F. Muell., W. centralis Macfarlane, W. latifolia Macfarlane and W. uniflora (R. Br.)Macfarlane as occurring in South Australia. Before this only one species, W. dioica (as Anguillaria dioica) was listed for South Australia (J.M. Black 1922, 1943). Macfarlane stated that he had seen no live material of South Australian species. The present author has made extensive field studies of taxa discussed in this paper, has cultivated most and studied herbarium material. Several trips have been made to other states to allow further comparisons to be made. For information on the nomenclatural history, general morphology, biology and ecology of Wurmbea see Macfarlane 1980.

Ovary Structure of the Genus Gyrogyne (Gesneriaceae, Epithemateae)
CSIRO PUBLISHING www.publish.csiro.au/journals/asb Australian Systematic Botany 16, 629–632 Ovary structure of the genus Gyrogyne (Gesneriaceae, Epithemateae) Yin-Zheng Wang Laboratory of Systematic & Evolutionary Botany and Herbarium, Institute of Botany, The Chinese Academy of Sciences, 20 Nanxincun, Xiangshan, Beijing 100093, People’s Republic of China. Email: [email protected] Abstract. The anatomical re-investigation of the ovary in the holotype of Gyrogyne subaequifolia W.T.Wang is carried out in order to clarify the ovarian structure of the genus Gyrogyne W.T.Wang (Gesneriaceae), a seemingly unusual ovarian structure according to its original description. The present anatomical re-investigation reveals that the ovary is, in fact, bilocular with a swollen axile placenta in the centre, that is, the median area of the membranous septum. The ovarian structure of G. subaequifolia shows, thus, a common feature frequently observed in the ovaries of Gesneriaceae rather than a unique ovarian characteristic that contributes to the family Gesneriaceae. The systematic placement of Gyrogyne and the relationship between Gyrogyne and allies are discussed.

One trait that could be improved upon is locule number, which can increase the practical edible mass of each tomato. To identify genes that may be responsible for this phenotype, we PCR-amplified, gel-imaged, and sequenced candidate genes in several heirloom tomato cultivars that naturally exhibit multiple locules. These candidate genes were selected from genes involved in the CLV-WUS feedback mechanism that act to control proliferation of apical meristems, which directly impact the characteristics of fruit. -
