BIOMORPHOLOGY OF THE GENUS PHLOMOIDES (LAMIACEAE) SPECIES: SEARCH FOR NEW DIAGNOSTIC CHARACTERS FOR TAXONOMY OF THE GENUS
Аннотация
To search for new biomorphological characters significant for taxonomy, the morphogenesis of Phlomoides agraria, P. tuberosa, P. tuvinica (subsect. Phlomoides), and P. alpina, P. oreophila, P. pratensis (subsect. Alpinae) was analyzed, as well as herbarium specimens of other species of the genus Phlomoides from different subsections. Manifestations of recapitulation by phyllotaxis in some representatives of the genus were considered and analyzed, and one of possible directions of somatic evolution within the genus was determined on this basis. During a comparative analysis of the morphogenesis of the above-mentioned species, biomorphological differences were revealed between closely related species: P. agraria, P. tuberosa (subsect. Phlomoides) and P. alpina, P. oreophila (subsect. Alpinae). We have established that these species, confined to certain vegetation zones, are characterized by the constancy of their life form. As an additional diagnostic feature, the structure of the underground part of the plants is proposed to use: P. agraria forms a long rhizome, P. tuberosa – a short one; P. oreophila – a caudex, and P. alpina – a short rhizome. A relationship was established between the shoot formation model, the peculiarities of the location of generative shoots on skeletal shoots and the belonging of the species to one of the clades identified in the course of molecular genetic studies, which indicates the prospects for using these characteristics in the taxonomy of the genus Phlomoides. Recapitulation by alternate phyllotaxis is described at the beginning of ontogenesis in P. agraria and P. tuberosa, both following the sympodial model of shoot formation. In monopodially growing plants of P. alpina, P. oreophila and P. pratensis, it is completely absent. It was found that P. tuvinica plants, which follow the monopodial model of shoot formation, retain alternate phyllotaxis on skeletal rosette shoots and opposite decussate phyllotaxis on axillary generative shoots throughout their ontogenesis. The presence of two phyllotaxis variants in P. tuvinica individuals suggests that this species is closest to the ancestral type, i. e. a non-durable semi-rosette monocarpic plant. It is assumed that somatic evolution proceeded from a non-durable monocarpic plant with a semi-rosette shoot to a perennial polycarpic plant through both monopodial and sympodial growth patterns of shoot structures. With monopodial growth of a plant, the shoot structure changes from the original semi-rosette to rosette, while in the case of sympodial growth of a plant, the semi-rosette structure of the shoot is retained.

GYNOECIUM AND OVULE STRUCTURE IN LYSIMACHIA NUMMULARIA AND L. PUNCTATA (PRIMULACEAE)
Аннотация
The data was analyzed and similarities and differences were identified in the structural peculiarities of the inflorescence, flower, gynoccium and ovule in Lysimachia punctata, L. nummularia and the previously studied species L. vulgaris. The inflorescences are mainly racemose. In L. vulgaris, however, the second axes repeat the first ones only in the lower part of the inflorescence, while in its middle and upper parts thyrses are formed. In L. punctata, the inflorescences are represented mainly by thyrses, while in L. nummularia the flowers are arranged oppositely, 2 in each node of its creeping shoots. The flowers are 5-merous, actinomorphic, the calyx and corolla are fused at the base. The stamen filaments are fused together into a tube, which is attached to the petals. In L. vulgaris and L. nummularia, this tube is short, but in L. punctata it covers the filaments almost completely. On the outer epidermis of sepals, petals, staminate filaments and gynoccium, glandular hairs are formed. The structure of their stalks differs in the number of cells: in L. vulgaris and L. punctata it consists of 2, and in L. nummularia of 3 cells. Similarities in the gynoccium structure are as follows: syncarpous type, lysicarpous variation; the presence of a synophore and columella in the placentary column; remains of 5 septa along the full length of the ovary; 5 septal vascular bundles that continue in the column. The features of difference are: the placentary column in the apical part is short and rounded in L. vulgaris, long and pointed, reaching the style canal in L. nummularia and L. punctata; different number and location of ovules in the ovary – there are many ovules located on 6 tiers in L. vulgaris, there are fewer ovules formed on 3 tiers in L. nummularia and L. punctata; the ovules are large in L. nummularia and relatively small in L. punctata and L. vulgaris; different structure of placentae – intrusive central-angular or all tiers in L. vulgaris, on the middle one in L. nummularia, middle and lower ones in L. punctata, simple central-angular on the upper and lower tiers in L. nummularia, and on the upper tier in L. punctata; the number of vascular bundles that innervate the synophore and continue into the placentary column is 7–10 in L. vulgaris and L. punctata, and 5 in L. nummularia. The ovules in the species we studied are characterized by a similar structure and are hemi-campylotropous, which is probably characteristic of many plants from other families with a lysicarpous gynoccium. The data obtained do not contradict cladistic constructions, according to which the studied species are treated as belonging to different groups, with Lysimachia vulgaris in one group, and L. nummularia and L. punctata in the other.

FLORISTIC RECORDS
VAUCHERIA SPECIES (VAUCHERIACEAE, XANTHOPHYCEAE) FROM THE NORTHERN DVINA RIVER MOUTH
Аннотация
In September 2024, samples with Vaucheria were collected in the Northern Dvina River mouth at the cities of Arkhangelsk and Severodvinsk (Northern European Russia). Five species were identified, including V. synandra, which is a new record for Russia. Vaucheria birostris and V. medusa are newly recorded for the Arkhangelsk Region. The morphology of these species is documented by microphotographs. New localities were established for V. intermedia and V. macounii.

NORTHERNMOST LOCALITIES OF SAWIA CANADENSIS (CHAROPHYCEAE, CHARACEAE) AND VAUCHERIA TAYLORII (XANTHOPHYCEAE, VAUCHERIACEAE) FROM THE LOWER LENA REGION (NORTH ASIA)
Аннотация
Sawia canadensis and Vaucheria taylorii were found in the northernmost locality of the both species distribution ranges. Vaucheria taylorii is a new species record for the Republic of Sakha (Yakutia). Both species were growing together in a small lake south of the Lena River delta, the northernmost continental locality for charophytes and freshwater Vaucheria in mainland Eurasia.

PROTECTION OF PLANT WORLD
ON THE NECESSITY TO PRESERVE OLD-GROWTH SPRUCE FORESTS IN UPPER REACHES OF THE PADOMA RIVER (ARKHANGELSK REGION)
Аннотация
In the massif of native old-growth spruce forests located at the junction of the Verkhnetoyemsky and Ustyansky districts of the Arkhangelsk Region, the species of plants, fungi and lichens listed in the Red Data Books of Russia (Calypso bulbosa, Lobaria pulmonaria and Sarcosoma globosum) or Arkhangelsk Region (Acolium karelicum, Arthonia vinosa, Chaeonheca gracillima, Corydalis solida, Poa remota, Pycnoporellus alboluteus, Ramalina thrausta) were found. The surveyed massif can be classified as a biologically valuable forest by both the structure of the tree stand and the presence and number of specialized and indicator species. The creation of a specially protected natural area within the boundaries of the studied forest massif is recommended.
