The paper substantiates the importance of research in the field of ecological morphology when introducing woody species to culture in more severe climatic conditions compared to natural habitats. A set of techniques used for introduction experiments with trees, shrubs and woody lianas is described. The authors have carried out a comparative analysis of life forms of the same species in the monsoon climate in the Far East in places of natural growth (according to literature data) and in the sharply continental climate of the Altai Mountains at the point of introduction (according to long-term observations). It has been revealed that the most frequent adaptive manifestation is the change of life form in the following directions: summer green tree above 10 m → summer green tree up to 10 m; summer green shrub above 2 m → summer green shrub 1–2 m. The least adapted ones were representatives of evergreen and wintergreen biomorphs. Berberis amurense , Corylus heterophylla , Cotoneaster dammeri , Pentaphylloides davurica , Lonicera chrysantha , Forsythia ovata , Eleutherococcus senticocus , Stephanandra incise , Rubus matsumuranus , Rubus crataegifolius , Rosa rugosa showed a high degree of winter hardiness (I score) among shrubs.

Neillieae was traditionally recognized as a small tribe in Rosaceae, which consists of Neillia, Stephanan- dra, and Physocarpus. Recently, Stephanandra was merged into Neillia based on molecular phylogenetic analyses, meaning that Neillieae now contains Neillia and Physocarpus. The genus Neillia is distinguished from Physocarpus by ovate to lanceolate leaves with acuminate to caudate apices, racemose or paniculate inflorescences, and a unicarpellate (rarely bicarpellate) gynoecium. Plants of Neillia are distributed from the Himalayas across China and Korea to Japan in the east, and south to Indonesia. This study provides a taxonomic treatment of Neillia based on a morphological exam- ination of herbarium specimens, including types, and field observations, as the second part of the taxonomic revision of the tribe Neillieae. A summary of the phylogeny of Neillia, keys to the species, nomenclatural reviews, descriptions, dis- tribution maps, and lists of specimens examined are provided. Twelve species with ten varieties are recognized in Neillia. A lectotype was designated here for the following species: N. sinensis f. glanduligera and N. thyrsiflora.

The tribe Neillieae, a small group of about 18 species in the Rosaceae, comprises three taxonomically difficult genera, Neillia, Physocarpus, and Stephanandra. The tribe, characterized by lobed leaves with persistent or deciduous stipules and ovoid, shiny seeds with copious endosperm, is strongly supported as a monophyletic group by a variety of lines of molecular evidence. Due to the high amount of morphological variation across the three genera and the species in tribe Neillieae, conflicting classification schemes and numerous species have been proposed over the past three centuries. However, no comprehensive systematic study of the group, including all species across their geographic ranges, has ever been undertaken. As part of a taxonomic revision of tribe Neillieae, a revision of Phys- ocarpus based on the morphological examination of herbarium specimens, including types, and field observation is presented. Artificial keys, comprehensive nomenclatural treatments, descriptions, distribution maps, and lists of spec- imens examined are provided. Six species in Physocarpus are recognized. A lectotype is here designated for the fol- lowing species: Opulaster pubescens, Opulaster ramaleyi, Spiraea opulifolia var. parvifolia, Spiraea opulifolia var. tomentella, Physocarpus michiganensis, and Physocarpus missouriensis.
