“…For several taxa, fresh or silica-gel-dried material was not available for DNA extraction, so recently collected herbarium specimens were used. Representatives of each of the 12 currently recognized genera (Thompson, 1976;Coode, 1987;Coode 2004) were obtained: five species of Aceratium (of c. 20 species; Coode, 2004; distributed from Celebes and Moluccas, New Guinea, New Hebrides to northeastern Australia; taxa sampled from northeastern Australia and New Guinea), all five extant species of Aristotelia (southeastern Australia, New Zealand, Chile, Argentina; Coode, 1985), two species of Crinodendron (four species ;Bricker, 1991;central Bolivia, central and southern Chile, southeastern Brazil, northwestern Argentina; taxa sampled from northern and southern Chile), four species of Dubouzetia (c. 11 species;Coode, 1987; Moluccas, New Guinea, New Caledonia, N. Australia; taxa sampled from New Guinea, New Caledonia and N. Australia), 13 species of Elaeocarpus (no recent monograph available, but the number of species is probably at least 300; M. J. E. Coode, Royal Botanic Gardens Kew, personal communication; widespread in Southeast Asia and distributed west to India, Madagascar and Mauritius, north to Japan, east to Hawaii and south to Australia and New Zealand; taxa sampled from Australia, New Guinea, and New Zealand), both species of Peripentadenia (northeastern Australia;Coode, 1987), one of the two species of Platytheca (Thompson, 1976;southwest Western Australia), three species of Sericolea (c. 11 species; Coode, 1981;New Guinea), six species of Sloanea (c. 120 species; Earle- Smith, 1954;Coode, 1983;Smith, 1996;India, Indochina, South China, Malesia, Australia, New Caledonia, Madagascar, tropical Americas; taxa sampled from Australia, New Guinea, and the Caribbean), six species of Tetratheca (c. 50 species; Thompson, 1976; R. Butcher, Western Australian Herbarium, personal communication; southern Australia; taxa sampled from across the range), both species of Tremandra (Thompson, 1976;southwest Western Australia), and one of the two species of Vallea (Jaramillo Azanza, 1988; Chile, Ecuador) (Appendix).…”

“…Aristotelia and Vallea form a robust group, with Sloanea, which is often considered isolated in Elaeocarpaceae (Coode, 1987), resolved as its sister. Coode (1985) proposed a phylogeny of Aristotelia and Vallea based on 11 (mostly reproductive) morphological characters. In a manually constructed cladogram, Aristotelia was monophyletic with the Australian species (A. australasica and A. peduncularis), forming a clade sister to a group comprising the other three species; in the latter group, the New Zealand taxa (A. fruticosa, A. serrata) formed a clade.…”

To better understand the historical biogeography of the southern hemisphere and evolutionary responses of plants to aridity, we undertook a detailed phylogenetic study of the predominantly southern family Elaeocarpaceae sensu lato (including Tremandraceae). Plastid trnL-trnF and nuclear ITS sequence data were analyzed using parsimony and Bayesian methods and molecular evolutionary rates calibrated using the Oligocene fossil record of Elaeocarpus mesocarps to estimate the minimum divergence dates. The results indicate the monophyly of all recognized genera and a placement for the former Tremandraceae (three genera and about 49 species of shrubby, dry-adapted Australian plants) within the widespread predominantly rainforest tree family Elaeocarpaceae (nine genera, over 500 species). The former Tremandraceae clade diverged from its sister (Aceratium + Elaeocarpus + Sericolea) during the Paleocene, after which it underwent a marked acceleration in evolutionary rate. Furthermore, this lineage diversified during the late Miocene, coincident with widespread aridification in Australian environments and extensive radiations of several sclerophyllous groups. The role of dispersal in explaining the current geographical distribution of Elaeocarpaceae is illustrated by Aristotelia. This genus, whose distribution was previously thought to reflect Gondwanan vicariance, is shown to have arrived in New Zealand from Australia at least 6-7 million yr ago.

NOTHOFAGUSAND PACIFIC BIOGEOGRAPHY

1995

— Gondwanan biogeography, particularly the relationships between southern South America, New Zealand, Australia, New Guinea and New Caledonia, has been much studied. Nothofagus is often used as the “test taxon”, and many papers have been directed at using Nothofagus to explain Gondwanan biogeography. Cladistic biogeographers, working on plant material, have generally failed to find congruence among taxa expected from the southern Pacific disjunctions. New morphological and molecular data on the phytogeny of Nothofagus have re‐opened the issue, and we analysed these data to construct a new hypothesis of the biogeography of the genus. We assembled all plant taxa for which we could find reasonably robust phylogenetic hypotheses, and sought a parsimonious biogeographical pattern common to all. Two analyses, based on different assumptions, produced the same general areacladogram. We use the general area‐cladogram, in conjunction with the fossil record of Nothofagus to construct a historical scenario for the evolution of the genus. This scenario indicates extensive extinction, but also suggests that Australia has a more recent relationship to New Zealand than to southern South America. This is not congruent with the current geological theories, nor with the patterns evident from insect biogeography. We suggest that concordant dispersal is an unlikely explanation for this pattern, and propose that the solution might be found in alternative geological hypotheses.

“…Of the five species in the genus Aristotelia, A. serrata is more closely related to the morphologically similar A. chilensis than it is to Australian species in the genus (Coode 1985). A. chilensis produces a basal cohort of leaves in spring, which mainly fall in autumn, and a distal cohort during summer which are retained until mid spring .…”

Winter leaf loss in the New Zealand woody flora

Approximately 27 species (c. 5%) of the New Zealand woody flora have a marked loss of leaves in winter, although only 10 species are consistently fully deciduous and no extensive vegetation type is dominated by them. There are no summer deciduous species. The deciduous habit appears in most cases to have evolved independently within New Zealand from either ancestors or immigrants with short leaf life spans. New Zealand deciduous or semideciduous species typically lose substantial numbers of leaves throughout the growing season, and leaf loss is often gradual throughout winter but accelerated by frost. The deciduous habit in New Zealand tends to be a leaf-or shoot-level feature reflecting short leaf life spans and winter stress on individual shoots, rather than a systematic feature of the canopy-level organisation of the plant. Degree of deciduousness varies with taxon, plant age, climate, and soil fertility. A physiological study of cooccurring fully deciduous (Fuchsia excorticata) and semideciduous (Aristotelia serrata) trees in the South Island established that higher growing-season productivity of Fuchsia compensated for carbon gain forgone over winter. However, Fuchsia was significantly favoured over Aristotelia only on the coldest sites. Aside from some inland basins of the South Island, New Zealand has milder winters than those that favour deciduous taxa globally, and this is the primary reason for the low incidence of deciduous species. Even so, a number of deciduous species are common throughout. New Zealand deciduous trees and shrubs are typically fast growing and are characteristic of seral or forest marginal habitat on nutrient-rich soils developed in recent alluvium or debris. The relatively low nutrient status of most New Zealand forest soils makes a deciduous phenology, with its necessarily high turnover of nutrients, less competitive than a nutrient-conserving evergreen phenology. Deciduous species are often also divaricating, or have close relatives that are, and share a preference for nutrient-rich soils with this growth form. This strong relationship between the two habits suggests both are, in part, adaptations to stressful climates by plants with high-productivity leaves.
