Significant Difference

The sex form of each species in the flora of the south-west of Western Australia was determined, and the proportions of the different forms compared with data available for South Australia. Although the western flora has been substantially isolated since at least the mid Tertiary, no significant difference in the proportion of hermaphrodite species from that of South Australia was found. A re-analysis of the sex forms of the flora of the British Isles was also made, and it was found that this flora has a higher proportion of non-hermaphrodite species than has either Western Australia or South Australia. The possible evolutionary significance of these observations is discussed.

Significant Difference

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

Pitjantjatjara is a dialect of the Western Desert Language (WDL) of central Australia (Douglas 1958). The Western Desert Language is a member of the south-west Pama-Nyungan group. Together with Warnman, it forms the Wati sub-group. It is spoken by 4000–5000 people, and covers the widest geographical area of any language in Australia, stretching from Woomera in central northern South Australia, as far west as Kalgoorlie and Meekatharra and north to Balgo Hills, in Western Australia. The main dialects, which differ most in regards the lexicon but also to some extent in grammar and phonology, include Pitjantjatjara, Yankunytjatjara, Ngaanyatjarra, Ngaatjatjarra, Southern Luritja, Pintupi-Luritja, Kukatja, Gugarda, Ngalia, Wangkatja, Wangkatha, Manyjilyjarra, Kartutjarra and Yurlparija. It is perhaps more accurately conceived of as a dialect chain, whereby a dialect such as Pitjantjatjara is mutually intelligible with its neighbours Ngaanyatjatjarra and Yankunytjatjara, but not with dialects more distant than these, such as Kukatja and Manyjilyjarra.

The genus Amperea Adr. Juss. contains eight species, six of which are confined to the south-west of Western Australia. The seventh occurs only in central Australia while the eighth ranges from central Queensland to Tasmania and extends to the south-east of South Australia. A. simulans, from Western Australia, is described as new, and A. xiphoclada var. papillata and A. xiphoclada var. pedicellata from New South Wales are recognised as new varieties; A. xiphoclada var. pedicellata is probably now extinct. Lectotypes are chosen for A. micrantha and A. volubilis. All species are described in detail and a key to identify them is provided. The diagnostic relevance of a range of attributes of the genus is reviewed as is its classificatory history.* The first of a projected series of revisions of genera traditionally included in Stenolobeae Benth., and others related to them, which are intended to form the basis of future Flora of Australia accounts.

Over the past 30 years in Western Australia (WA), there has been heated debate about the future use of the remaining karri and jarrah forests in the south-west of the State. This debate revolves around policy proposals from two social movements: one wants to preserve as much of the remaining old-growth forests as possible, and an opposing movement supports a continued

Eucalyptus Wandoo

IN 1908, Ron's grandfather, Issac Gray, took up an uncleared block of land 15 km north of Frankland in the south-west of Western Australia (see Fig. 1, Hobbs 2003). During that time he ran a few cattle in the bush and clearing of the native woodlands of Wandoo (white gum) Eucalyptus wandoo, J arrah E. marginata and Marri (Redgum) E. calophylla was slow and tedious. Ron's parents took over the farm in 1947, and with the advent of the bulldozer, clearing of Watkin's property and surrounding district began in earnest during the 1950s. Clearing continued as fast "as money permitted", until almost the last natural vegetation was knocked down in 1978 (Fig. 1). Annual pastures with some cropping (for supplementary feed) were the main source of fodder for sheep and cattle.

This paper presents a new Altivasum found off Jurien Bay, Western Australia at 60 m. This new species expands our understanding of the distribution, and in particular extends the northern range of Altivasum, in the South-west Marine Region. Altivasum pauladellaboscae n. sp. is more rhomboidal than A. hedleyi Maxwell and Dekkers, 2019, which is elongated, and has the formation of tubular spines on the shoulder of axial fold on the later whorls of the spire; these spines are not formed in A. pauladellaboscae n sp. Altivasum pauladellaboscae n sp. differs from A. profundum Dekkers and Maxwell, 2018 in having acute shoulder nodules. The South Australian, A. flindersi Verco, 1914 lacks the fibriated subsutural band found in A. pauladellaboscae n. sp. Altivasum clarksoni Maxwell and Dekkers, 2019 is geographically isolated and morphologically distinct, being more elongated and fibriated. This paper brings the number of described Altivasum species to five
