Introduction: This key is based on vegetative characteristics, and therefore also of use when cones are absent. - Use a 10× hand lens to evaluate stomata, bud, leaf scar, leaf apex and pubescence in general. - Look at the entire plant and especially the most healthy shoots. Young specimens, shade, coning, top crown and strong shoots give an atypical view. - Beware of hybridisation, especially with plants raised from seed other than wild origin.

Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

Vietnam’s conifer flora has approximately 34 species that are indigenous to the country, making up about 5% of conifers known worldwide. Although conifers represent only less than 0.3% of the total number of higher vascular plant species of Vietnam, they are of great ecological, cultural and economic importance. Most conifer wood is prized for its high value in house construction, furniture making, etc. The decline of conifer populations in Vietnam has caused serious concern among scientists. Threats to conifer species are substantial and varied, ranging from logging (both commercial and subsistence), land clearing for agriculture, and forest fire. Over the past twelve years (1995-2006), Vietnam Botanical Conservation Program (VBCP), a scientific cooperation between the Missouri Botanical Garden in Saint Louis and the Institute of Ecology and Biological Resources in Hanoi, has conducted various studies on this important group of plants in order to gather baseline information necessary to make sound recommendations for their conservation and sustainable use. -

To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two western North American species, T. heterophylla and T. mertensiana, and a clade of Asian species within which one of the eastern North American species, T. caroliniana, is nested. The other eastern North American species, T. canadensis, is sister to the Asian clade. Tsuga chinensis from Taiwan did not group with T. -

Abstract: Amentotaxus, a genus of Taxaceae, is an ancient lineage with six relic and endangered species. Four Amentotaxus species, namely A. argotaenia, A. formosana, A. yunnanensis, and A. poilanei, are considered a species complex because of their morphological similarities. Small populations of these species are allopatrically distributed in Asian forests. However, only a few codominant markers have been developed and applied to study population genetic structure of these endangered species. -

The Yunnan Province of China is wet and warm enough to support magnificent forests. However, many mountains in the region are covered by a shrubland for- mation dominated by an unusual pine, the shrubby and multistemmed Pinus yunnanensis (Yunnan pine; Fig. 1). This formation is natural, and not the product of forest degradation; and fire appears to be a major factor explaining the features of this pine. This region has a subtropical monsoon climate influenced by both the FIG. 1.
