Check-list of Veronica subg . Pseudolysimachium ( Plantaginaceae ) of Siberia Конспект вероник подрода Pseudolysimachium ( Veronica , Plantaginaceae )

Поступило в редакцию 28.04.2014 Submitted 28.04.2014 Принято к публикации 09.09.2015 Accepted 09.09.2015 Summary. Here, we present a critical check-list of Veronica subgenus Pseudolysimachium (W. D. J. Koch) Buchenau (Plantaginaceae Juss.) in Siberia, represented by 4 sections, 19 species and 4 subspecies. Two subsections of the subgenus (Pinnatae и Dauricae) are elevated to the taxonomic rank of a section. The Latin diagnosis for V. linariifolia var. baicalensis Boriss. is given, which has been previously described only in Russian.

In the last decade renewed interest has been given to the study of the subgenus.This interest has been raised by the polymorphism and frequent hybridization and polyploidy in the group.This has led to considerable systematic complexity in the group and many taxonomic questions.Based on phylogenetic studies based on nuclear and plastid DNA regions, the relationship of the subgenus within the genus has been clarified (Albach, Chase, 2001;Albach, Fischer, 2003;Albach et al., 2004Albach et al., , 2005)).However, relationships within the subgenus remain obscure.
In recent years, the renewed interest has led to studies of comparative morphology and ecogeography of the species in the Altai Mountains, which revealed unanticipated taxonomic diversity (Kosachev, 2003(Kosachev, , 2010;;Kosachev, German, 2004).Before these studies subgenus Pseudolysimachium was studied in Siberia only floristically in some regions.For the whole former USSR only a few In the process of assembling this critical conspectus we investigated material from the following herbariums ALTB, IRK, LE, MHA, MW, NS, NSK, TK, and the herbarium of Altai botanical garden (Ridder, Kazakhstan).
In the conspectus we provide the main bibliographical information (regional floras and determination keys) that summarize the floristic knowledge of the investigated territory.We state all synonyms relevant for the territory of Siberia, as well as information on types, taxonomy, ecology, distribution area within Siberia and chromosome number/ploidy level.Distribution in the region follows the floristic districts of the "Flora of Siberia" (Malyshev, 1988).
General distribution: Scandinavia, Central to Western Europe, Northern Mediterranean, Caucasus, Russia (European part, Western and Eastern Siberia, Far East), Central Asia, Near East, Dschungarija-Kaschgarija, China, Japan, North America.
Note 1.In the Altai and Sayan Mountains V. longifolia var.macrantha Boriss. is found with longovate leaves and glandular calyx.
Note 2. The typical subspecies is certainly central for the evolution of the endemic V. sieboldiana Miq., V. subsessilis (Miq.)Carriere, V. ovata Nakai, that grow in Japan, Korea and the island of Tschetschzhudo.
Note 3. The main differences between V. maritima L. and V. longifolia L. are the calyx indumentum (simple long hairs in the former, short glandular hairs in the latter), the length of the bracts (longer or equal than pedicels in the former, or equal to shorter in the latter) and leaf base (cuneate to cordate in the former, rounded in the latter).Furthermore, leaves are often in whorls of 3-4 leaves in the European V. maritima and opposite in the Asian V. longifolia (Trávniček, 2000).The distinction is, however, questionable given the breadth of variation in the European part and the prevalence of hybridization.

V. taigischensis
In Taiga-forest.Distribution in Siberia: Central Sib.: KR -We (known only from type locality).
General distribution: endemic.Veronica sajanensis has once been recorded from Mongolia (Neuffer et al., 2003) but relevant record was based on the misidentified specimen of V. schmakovii (German et al., 2003).
Note: The species takes on an intermediate position between section Longifoliae and Spicatae (Elenevsky, 1978), although an influence of section Pinnatae is possible based on DNA-sequence analysis (Kosachev, Mayland-Quellhorst, Albach, unpublished).Note: At Baikal Lake (Kultuk) and in the north of Mongolia one can find specimens with broadlanceolate leaves, dense indumentum of stem and petiole and with large pinkish flowers.This variation has been described in Russian only: V. linariifolia var.baicalensis Boriss. (1955, Fl. USSR, 22: 389).Therefore, we here provide the Latin diagnosis and designate the type: Folia late lanceolata.Caulis et petioli foliis dense pubescentia.Corolla magna subroseus.
Based on morphological characteristics, this species has similarities with V. spuria.Therefore, reports of V. spuria for the Flora of Mongolia may be wrong (see Kosachev, 2010;Smirnov et al., 2003).
Type: lectotype of the subgenus.
Steppe and rocky slopes, steppes, dry pine or lark forest.
General distribution: Central Europe, Russia (European part, Western and Eastern Siberia), Far East, Central Asia, Mongolia, China.
