3-O-acetyl pomolic acid methyl ester and p-coumaric acid methyl ester were isolated from the root of Spiraea prunifolia var. simpliciflora $N_{AKAI}$ and their structures were identified on the basis of spectral data.

A Phloeospora leaf spot disease on Spiraea prunifolia var. simpliciflora was noticed to commonly occur in Korea. The causal organism of the disease was identified as Phloeospora spiraeicola based on the morphological characteristics of conidiomata and conidia. Pathogenicity of the fungus was proved by artificial inoculation. This is the first record of Phloeospora leaf spot in Korea.

Korean folk medicine 'JoPabNaMu' has been mainly used to cure removal of fever and neuralgia. With regard to the botanical origin of 'JoPabNaMu', it has been considered to designate the stem of Spiraea species (Rosaceae), but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JoPabNaMu', the anatomical characteristics of the branch of Spiraea species growing wild in Korea were studied. As a result, 'JoPabNaMu' was proved to be the branch of Spiraea prunifolia var. simpliciflora.

The petiole anatomy of three sections (sects. Calospira, Chamaedryon, and Spiraria) in the genus Spiraea (Rosaceae), which are distributed/cultivated in Korea, was studied and described in details. The vascular bundle system of the distal, medial, and proximal parts of the petiole were studied using LM with the aim of documenting any differences in vascular anatomy. Significant variation of anatomical characters was found in petiole shape (dichotomy, lens or subcircular in outline), presence of two distinct lateral wings, the thickness of epidermis, number of vascular bundles, length of ventral axis, length of dorsiventral axis, width of median vascular bundle, and length of median vascular bundle. All features were compared and we concluded that petiole anatomical characters can be useful for providing diagnostic features to distinguish the studied taxa. A key for identifying the Spiraea taxa in Korea based on their petiole anatomical characters is also provided.

Spiraea prunifolia f. simpliciflora Nakai is a perennial shrub widely used for horticultural and medicinal purposes. We simultaneously obtained the complete plastid genome (plastome) and nuclear ribosomal gene transcription units, 45S nuclear ribosomal DNA (nrDNA) and 5S nrDNA of S. prunifolia f. simpliciflora, using Illumina short-read data. The plastome is 155,984 bp in length with a canonical quadripartite structure consisting of 84,417 bp of a large single-copy region, 18,887 bp of a short single-copy region, and 26,340 bp of two inverted repeat regions. Overall, a total of 113 genes (79 protein-coding genes, 30 tRNAs, and four rRNAs) were annotated in the plastome. The 45S nrDNA transcription unit is 5,848 bp in length: 1,809 bp, 161 bp, and 3,397 bp for 18S, 5.8S, and 26S, respectively, and 261 bp and 220 bp for internal transcribed spacer (ITS) 1 and ITS 2 regions, respectively. The 5S nrDNA unit is 512 bp, including 121 bp of 5S rRNA and 391 bp of intergenic spacer regions. Phylogenetic analyses showed that the genus Spiraea was monophyletic and sister to the clade of Sibiraea angustata, Petrophytum caespitosum and Kelseya uniflora. Within the genus Spiraea, the sections Calospira and Spiraea were monophyletic, but the sect. Glomerati was nested within the sect. Chamaedryon. In the sect. Glomerati, S. prunifolia f. simpliciflora formed a subclade with S. media, and the subclade was sister to S. thunbergii and S. mongolica. The close relationship between S. prunifolia f. simpliciflora and S. media was also supported by the nrDNA phylogeny, indicating that the plastome and nrDNA sequences assembled in this study belong to the genus Spiraea. The newly reported complete plastome and nrDNA transcription unit sequences of S. prunifolia f. simpliciflora provide useful information for further phylogenetic and evolutionary studies of the genus Spiraea, as well as the family Rosaceae.

Genus Spiraea is composed of many long-lived woody species that are primarily distributed throughout Asia and Europe. In this study, we evaluated a representative sample of the 38 taxa in the world, including 14 in Korea, with nuclear ribosomal DNA internal transcribed spacer sequences (ITS) to estimate genetic relationships within the genus. The molecular data allowed us to resolve well-supported clades in the taxa. In 47 world accessions (38 taxa: 14 Korean taxa, 33 world taxa, and 9 overlapping taxa), total alignment length was 689 positions, of which 452 were parsimony informative, 527 variable, 75 singleton, and 159 constant characters. Although the phylogenic tree showed that many taxa of genus Spiraea were well separated from each other, many branches were not congruent with the morphological characteristics and geographical distributions of the genus. There were 430 segregating sites and the nucleotide diversity (${\pi}$) value was 0.281. Under the neutral mutation hypothesis, the probability that the Tajima test statistic (D) is positive (2.325) is more than 0.5. Therefore, there may be a site at which natural selection, which increases genetic variation, is operating.

Spiraea prunifolia var. simpliciflora (Rosaceae) is a deciduous. latifoliate shrub growing in most parts of Korea. The roots of this plant have been used for malaria, as antipyretics and emetics. From the roots of this plant, sterol glycoside and two triterpenoids were isolated and the structures were elucidated by chemical and spectroscopic methods. They were identified as $3{\beta}-hydroxyurs-12-ene-28-oic$ acid (ursolic acid.1), $2{\alpha}$, $3{\beta}$, $19{\alpha}-trihy-droxyurs-12-ene-28-oic$ acid (tormentic acid.2) and ${\beta}-sitoste-rol-3-O-{\beta}-D-glucopyranoside$ (3).

Seven phenolic compounds were isolated from the leaves of Spiraea salicifolia. Their structures were characterized as cinnamic acid, ${\rho}-hydroxy$ cinnamic acid, ${\rho}-methoxy$ cinnamic acid, $1-O-coumaroyl-{\beta}-D-glucopyranose$, $1-O-caffeoyl-{\beta}-D-glucopyranose$, hyperoside and quercetin $3-O-(6'-O-{\alpha}-L-arbinopyranosyl)-{\beta}-D-galactopyranoside$ by chemical and spectroscopic evidence.

Spiraea prunifolia Sieb. et. Zucc. var. simpliciflora Nakai (Rosaceae) is distributed in Korea, and used as a folk medicine for antipyretic, antimalarial and emetic. Sterols were obtained from the methanolic extract of the root of above plant. The composition of sterols are campesterol and ${\beta}-sitosterol$ which has been determined by gaschromatographic analysis.
