“…Due to the allopatric distribution of Mediterranean Abies, our marker with low evolutionary rates and transmission by seeds, is suited to differentiate species or species groups of interest. This requirement is not fulfilled by paternally inherited cpDNA variants as several variants occur within Abies species and many of them are shared among species (PARDUCCI and SZMIDT, 1999;KORMUTAK et al, 2004;LIEPELT et al, unpublished data).…”

The unambiguous identification of closely related species is useful for many practical purposes in forest tree species. For example, international laws require timber identification and the control of the origin of forest reproductive material. In this paper, we present a mitochondrial DNA marker which can be used to differentiate among groups of fir species (Abies spp.). Eight Mediterranean and one North American fir species (used as reference) were analysed at the fourth intron of the NAD subunit 5 gene. A total of six different haplotypes was identified, one in the American Abies concolor, the other five in Mediterranean species. Two different haplotypes were found each in the widespread A. alba and in A. cephalonica, one haplotype being shared among the two species. A single species specific haplotype was found in the near-eastern A. cilicica. The two southwestern species A. pinsapo and A. numidica shared one haplotype. The fifth haplotype was shared by all remaining eastern Mediterranean firs, A. cephalonica, A. bornmuelleriana, A. equi-troiani, and A. nordmanniana. Differences in haplotype sequences were mainly due to large insertions/deletions. Agarose gel electrophoresis thus provides a fast, cheap and reliable diagnosis method for species or species group identification.

“…Abies alba sampies were also taken in Mount Martinier-La Mascarina in the municipality of Forcayo EI Comato (AAI-5), in the province of Huesca, and sampies of A. numidica from the wood collection ofthe Royal Botanic Garden, Kew (K-Jw 18393) and the Nationaal Herbarium Nederland (UNI92) were also used for comparison with the pinsapo fir wood, as the Mediterranean fir group is a c10sed group and is very differentiated from the groups in Asia and North America (Kormutak et al 2004). In addition, this group supports the hypothesis of hybridisation in the fir species (Conte & Cristofolini 2003).…”

This study describes the structure of the wood of Abies pinsapo from samples taken from its three natural distribution areas in the Iberian Peninsula (Sierra de Grazalema, Sierra de las Nieves and Sierra Bermeja) and compares them with the varieties from the north of Africa, Abies pinsapo var. marocana from the Talassemtane mountains and A. pinsapo var. tazaotana from the Tazaout mountains. All the samples were collected in their regions of provenance. To put the results into perspective, a comparison was also made with the wood of Abies alba and A. numidica. The wood of the Iberian A. pinsapo and of its two varieties from the Rif mountains in Morocco is anatomically similar, and there are no qualitative differences that enable the wood to be differentiated except for the presence of resin deposits in the tracheids adjacent to the rays in the samples from Grazalema. Quantitatively, for tracheid diameter and tracheid length there are statistically significantly differences (p<0.05) between those of Spanish provenance and the Moroccan varieties, but for tracheid pit diameter, largest diameter of cross-field pits and tall ray frequency the samples from Sierra Bermeja have more in common with the African samples.

“…Frequent hybridization between Picea mariana and P. rubens, for example, creates numerous intermediate forms that are difficult to distinguish from parental species (Bouillé et al 2011). Hybridization has been reported as frequent in some genera of Pinaceae (Lanner and Van Devender 1998;Semerikov and Lascoux 2003;Kormatak et al 2004;Bouillé et al 2011;Xiang et al 2015), but there is little evidence for current hybridization in Tsuga. Tsuga caroliniana and T. canadensis are partially sympatric, but hybrids have not been documented.…”

A New Species and Introgression in Eastern Asian Hemlocks (Pinaceae: Tsuga)

Species delimitation in Pinaceae is often challenged by limited morphological differentiation and introgression. In Tsuga (hemlocks), species delimitation has been most challenging among northeastern Asian taxa, where the species are weakly marked morphologically and range in number from three to five in previous studies. Two low-copy nuclear four-coumarase-ligase (4CL) genes and morphology strongly support a clade of the Japanese endemic T. diversifolia and T. sieboldii from Japan and Ulleung island (Ulleungdo) in Korea. This clade is here referred to as the oceanic hemlocks. 4CL strongly supports a sister-group relationship of the widespread northeastern Asian T. chinensis and eastern North American T. caroliniana. In contrast, chloroplast genomes, which are markedly reduced in Tsuga and relatives, strongly support Japanese T. sieboldii as sister to T. chinensis and moderately support T. caroliniana as sister to a clade of T. diversifolia and hemlocks from Ulleungdo. These divergent topologies suggest chloroplast capture of T. chinensis by Japanese T. sieboldii. Ulleungdo hemlocks are distinct from other northeastern Asian species in leaf and cone morphology and phenologically in common-garden observations. We therefore describe these hemlocks as a new species, T. ulleungensis.
