title: Identification and the role of hybridisation in Pittosporum

authors: Carrodus, Susan Kathleen

subjects: Pittosporum  turneri

abstract: Godley (1985) proposed that species which have separate juvenile and adult forms may be derived from hybridisation, and proposed that the rare, heteroblastic species P. turneri is a putative hybrid. This study aims to identify whether Pittosporum turneri is derived from hybridisation between a divaricating shrub (P. divaricatum) and a non-divaricating tree (P. colensoi), and to improve resolution of relationships among very closely related species within the genus Pittosporum. A combined approach was used to test the origin of P. turneri. Phylogenetic analysis of the maternally inherited trnT-trnL region of chloroplast DNA was undertaken to compare with a phylogeny based on the biparentally inherited internal transcribed spacer of nuclear ribosomal DNA (ITS) for all New Zealand Pittosporum species. Additionally, inter simple sequence repeats (ISSR's) and allozymes were used in an attempt to identify hybridisation between P. colensoi and P. divaricatum. A morphological study was undertaken to determine whether P. turneri is morphologicaly intermediate to the putative parents. Cross-pollination between the putative parents of P. turneri was also undertaken in the wild between female flowers of P. divaricatum and male flowers of P. colensoi to investigate whether hybridisation between these co-existing species is possible. 

The trnT-trnL region resolved several clades within the New Zealand Pittosporum previously unresolved by the ITS region alone. P. turneri has the same trT-trnL sequence as P. divaricatum, implicating P. divaricatum as the maternal parent. The profile of ISSR bands in P. turneri, exhibit additivity of bands found in P. colensoi and P. divaricatum, supporting a hybrid origin of P. turneri. Morphological analyses also show that P. turneri is intermediate to P. divaricatum and P. colensoi. The cross-pollination experiment was unsuccessful and no seedlings germinated, although four seeds appeared viable. It is proposed that P. turneri has a hybrid origin, however this finding needs to be supported by further work.

title: Thomas William Carr: a Te Aroha storekeeper and speculator

authors: Hart, Philip

abstract: Thomas William Carr arrived in New Zealand in January 1881 accompanied by his large family and, reportedly, with extensive business experience and a large amount of capital. After first settling at Gisborne he moved to Te Aroha in mid-1882, acquiring land in the township and nearby and establishing stores at Te Aroha, Waiorongomai, Quartzville, and Shaftesbury. He was involved in a variety of commercial activities, and invested in local mining. He was also prominent in the community in general, including in the Anglican Church.
In early 1883, it all fell apart. After being adjudged bankrupt, he was shown to have been careless and indeed reckless in running his businesses; and instead of having large amounts of capital at his disposal, he had started with no capital at all, prompting suggestions of fraudulent dealings. After others acquired his properties and businesses, he fled New Zealand to try his luck in Australia, where he was much more successful. 
Others involved with him also went bankrupt, for his bankruptcy was by no means unusual.

title: Claiming collective space: Kaupapa Maori in psychology

authors: Levy, Michelle Patricia

subjects: Maori

abstract: From its inception, the Psychology Department at the University of Waikato has had a focus on issues of culture, particularly those of relevance for Maori, with these early foundations laid by Emeritus Professor James Ritchie, who in 1965 took up the founding chair of the Department. These foundations have continued to be built on, utilising a variety of different strategies. Drawing on a research base which has emerged primarily from within the Maori and Psychology Research Unit at Waikato University, this paper explores strategies which have served to carve out and claim space for Maori, both within the department, and within the wider discipline of psychology.
