Callitroideae

Belongs within: Cupressaceae. The Callitroideae are a clade of cypresses, united by molecular data, that are distributed in the Southern Hemisphere. Most genera are found in Australasia and South America with the genus Widdringtonia endemic to Africa (Mao et al. 2012). <==CallitroideaeMM12 |–PapuacedrusMM12 | |–P. papuanaMM12 | `–P. prechilensisMM12 `–+–AustrocedrusMM12 | |–A. australisMM12 | `–A.… Continue reading Callitroideae

Araucariaceae

Belongs within: Cupressophyta. The Araucariaceae is a family of thirty-five living species of conifer found in South America and the south-western Pacific region. Members of the genus Agathis have hard and smooth bark and petiolate leaves; species of Agathis are found between the Philippines, eastern Australia and Polynesia with a single species A. australis, the… Continue reading Araucariaceae

Coniferophyta

Belongs within: Spermatophyta.Contains: Ginkgoales, Umkomasiales, Peltaspermales, Cordaitales, Dicranophyllales, Miroviaceae, Doliostrobaceae, Voltziales, Pinaceae, Cheirolepidiaceae, Cupressophyta. The Coniferophyta have been recognised as a clade of gymnosperms including conifers, the ginkgo Ginkgo biloba, and the Palaeozoic Cordaitales. Members of this clade have simple, dichotomously veined leaves, simple strobili in the axils of the leaves, and platyspermic seeds (Doyle… Continue reading Coniferophyta

Doliostrobaceae

Belongs within: Coniferophyta. The Doliostrobaceae were early Palaeogene conifers known from Europe that bore some resemblance to modern Araucariaceae. Characters (from Kvaček 2002): Wood structure with abietoid pitting of tracheids and doliostroboid (not bordered) pits in cross field of branch wood, lacking ray tracheids and resin channels. Foliage shoots bearing polymorphic, helically arranged needle leaves,… Continue reading Doliostrobaceae

Voltziales

Belongs within: Coniferophyta. The Voltziales are early conifers known from the Late Carboniferous and Early Permian. Members were relatively small trees bearing plagiotropic lateral branches of determinate growth producing terminal cones (Rothwell et al. 2005). <==Voltziales [Walchiaceae] |–+–Genoites patagonicaRMH-C05 | `–FerugliocladaceaeC93 | |–Ugartecladus genoensis Archangelsky & Cúneo 1987C93 | `–FerugliocladusRMH-C05 | |–F. patagonicus (Feruglio) Archangelsky… Continue reading Voltziales

Pinus subgenus Pinus

Belongs within: Pinaceae. The type subgenus of Pinus includes the yellow and hard pines, characterised by the presence of two fibrovascular bundles per needle. <==Pinus subg.

Abies

Belongs within: Pinaceae. Abies, the firs, is a genus of conifers with erect seed cones native to the Northern Hemisphere. Leaf scars are smooth, round and flush with the surface of the stem (Hickman 1993). The bristlecone fir Abies bracteata is a distinctive species restricted to the Santa Lucia Mountains of central California, distinguished by… Continue reading Abies

Pinus subgenus Strobus

Belongs within: Pinaceae. The subgenus Strobus of the genus Pinus includes the white and soft pines, in which a single fibrovascular bundle is present in each needle. <==Pinus subg. Strobus |–+–+–P.

Podocarpaceae

Belongs within: Cupressophyta.Contains: Podocarpus. The Podocarpaceae are a family of more than 150 living species of mostly Southern Hemisphere conifers. Some are dominant forest species within their range and are used for timber. Many species produce fleshy ‘pseudo-fruits’ (really an enlarged seed scale) with seeds that are animal-dispersed as with many true fruits. In Podocarpus… Continue reading Podocarpaceae

Cupressaceae

Belongs within: Cupressophyta.Contains: Taxodioideae, Callitroideae, Cupressoideae. The conifer family Cupressaceae includes cypresses (Cupressus), junipers (Juniperus) and related taxa. The family has previously been divided between the Cupressaceae sensu stricto (with leaves opposite or whorled, comprising Callitroideae and Cupressoideae) and Taxodiaceae (with leaves mostly alternate), but the latter is now recognised as paraphyletic to the former… Continue reading Cupressaceae
