“…Among them the conifers from Taxaceae and Cupressaceae are of high importance as ornamental trees. Phylogenetically these families are distant from Pinaceae (Quinn & Price, 2003). Representatives of these families: European Yew and Mediterranean cypress were found to be inedible for the larvae (Table 1).…”

The performance of young larvae of the potentially invasive Siberian moth Dendrolimus sibiricus Tschtv. has been studied for the first time on the native and exotic coniferous species which are widely distributed and of considerable commercial value in Europe. Picea, Abies, the introduced Pinus species (five‐needle pine only), and species from the exotic genera Pseudotsuga and Cedrus (all Pinaceae) are found to be suitable hosts for pest development. Two‐needle pines and species from non‐native Tsuga (also Pinaceae) are poor hosts in terms of larval performance though they may support growth of neonates (most sensitive to food quality). Coniferous species from other families: Taxaceae and Cupressaceae are inedible for the pest. The fact that the Siberian moth is able to survive and develop on all the tested genera of Pinaceae and that some of them constitute two thirds of the European forests underline how harmful this defoliator could be in the case of its introduction into European countries.

“…While acknowledging recent phylogenetic studies based on molecular data (Gadek et al, 2000; Quinn and Price, 2003), we follow the taxonomic framework in Farjon's (2005) Cupressaceae monograph because of his comprehensive, evolutionary treatment of morphology across the family. Terminology for foliage forms follows Offler (1984; see also Figs.…”

The 51.9 Ma Laguna del Hunco (LH) and 47.5 Ma Río Pichileufú (RP) floras from Patagonia, Argentina are unusually rich, angiosperm-dominated assemblages with living relatives in the low-latitude West Pacific, neotropics, and temperate southern latitudes. The diverse gymnosperms in these floras are important for Gondwanan biogeographic history and paleoclimatic interpretations. "Libocedrus" prechilensis Berry 1938 (Cupressaceae), previously known only from the holotype (RP), a vegetative branch, is revised here based on new material from both localities, including a seed cone attached to a shoot with cuticle (LH). Characters of these fossils are diagnostic of monotypic Papuacedrus (highlands of New Guinea and Moluccas). Living P. papuana is most abundant in cloud forests receiving up to 4 m rainfall annually, whereas Austrocedrus (Libocedrus) chilensis, the basis of comparison when the fossil species was named, inhabits dry, cold steppe margins to mediterranean climates in southern South America. We establish Papuacedrus prechilensis comb. nov., which simultaneously invalidates a southern South American connection for the fossil floras and reveals a link to West Pacific montane rainforests. Combined evidence indicates a biome similar to extant subtropical, or tropical montane, rainforests that persisted for at least 4.4 Myr, linking elevated floral richness to abundant rainfall.

“…Today, the family represents the largest and most diversified group of conifers, growing mainly in altitudinal mesic forests, either mixed with angiosperms or in nearly pure stands (Quinn & Price, 2003). In colder latitudes down to coastal areas, such as on South Island of New Zealand, they experienced oceanic climates (Eckenwalder, 2009).…”

Paleogene imbricate-leaved podocarps from King George Island (Antarctica): assessing the geological context and botanical affinities

Imbricate-leaved podocarps (Dacrydium s.l.) are the dominant conifer remains in the Upper Cretaceous and Cenozoic successions of King George Island, increasing its abundance in the post-Late Paleocene strata and maintained until the Early Oligocene times, with poor taphoflora registered in the last. However, a more precise taxonomic relationship of their remains was ever difficult given the fragmentary nature of the fossils and most known from ex situ material. In new field works and collections looking for the original levels, the recent phylogenetic approaches proposed and comparisons with extant floras have been applied to these fossils, and have helped to clarify their taxonomic status and their preferable association with the Upper Paleocene-Lower Eocene levels. The two kinds of foliage discussed here initiated the taxonomic revision of the Podocarpaceae related fossils on the island and attest to a modern affinity with Dacrydium vel Halocarpus and Dacrycarpus, which was in part proposed by previous works. Those genera comprise today an important component of the eastern Southern Hemisphere forests, and their occurrence in the Antarctic Peninsula areas during the Paleogene supports a broader distribution in the past and attests to the importance of the ancient Antarctic coastal areas in the modern distribution of the Podocarpaceae.RESUMO -As Podocarpaceae são o principal grupo de coníferas nas floras do Cretáceo-Paleógeno da ilha King George, Península Antártica e, após o final do Paleoceno, tipos dotados de folhas pequenas e imbricadas, inicialmente agrupados em Dacrydium s.l., passam a ser dominantes nas assembléias. O caráter incompleto dos fósseis, que dificulta uma atribuição taxonômica mais precisa, fez também com que este epíteto genérico, sem afinidades filogenéticas bem estabelecidas, fosse muito utilizado nos primeiros estudos feitos. Novas análises e a ampliação das coletas, embora não tenham solucionado de todo este problema, mostraram ser úteis para tornar mais precisos os tipos de Podocarpaceae presentes. Neste trabalho, dois morfotipos são revistos e sugerida sua afinidade preferencial com Dacrydium vel Halocarpus e Dacrycarpus, hoje importantes componentes dos biomas do setor oriental do Hemisfério Sul. São igualmente localizados de modo mais preciso e a partir de novos trabalhos de campo, os níveis com plantas do Monte Wawel (= Pontal Hennequin), na baía do Almirantado, previamente conhecidos a partir de material ex situ, o que permitiu propor uma idade Eoceno Inferior para estes depósitos. A presença destes gêneros de Podocarpaceae em áreas da Península Antártica durante o Cenofítico, não apenas confirma sua ocorrência mais ampla no passado, como o importante papel exercido pelas áreas costeiras da Antártica na moderna distribuição da família.
