  30. Alexeeva N.B. Identification and preservation of rare species of the genus Iris L. //Annual Bulletin. Irises. М., 2007. P. 64-66.
    – Since all species of Russian flora are interesting for introduction and selection and some of them has been successfully tested ex situ for more than 200 years one can draw a conclusion that only those species which are vulnerable in situ and show unstable results ex situ are in jeopardy. Their preservation requires creation of various territorial forms of protection (in separate regions of the Federation).
  31. Alexeeva N. Report on Russian-American Botanical Conference //Annual Bulletin. Irises. М., 2007. P. 62-64.
    – In September 2005 Russian and American Botanists celebrated 30th anniversary of their cooperation in the field of protection of rare and endangered species of plants and plant introduction in the framework of bilateral Russian-American Agreement on Protection of the Environment. 80 participants (33 from Russia and more than 40 from the USA) attended the Conference which included 6 sections. One of them – Botanical Science – covered issues of methods of preservation in situ and ex situ. A very important section was devoted to education of population and covered issues for enhancement of awareness of the population on the necessity to preserve plants, work with children and youngsters etc. The main goal of the trip – to set new contacts between Russian and American scientists - was achieved.
  32. Alexeeva N.B. I. ruthenica //In the World of Plants. М., 2007. № 10. P. 20-21.
    – I. ruthenica is widespread in southern areas of Siberia, it was introduced long ago and has been showing positive results. It is frost-resistant and can stand oversaturation. The species requirements are quite modest and agrotechnology is rather simple. It can be located in the northern side of the rock garden. Unfortunately, the species has not been used in selection until now.

Growing the species in the Far East had not been confirmed for more than half a century. In 2000 3 scattered populations were found. Nowadays they are reducing their habitat both due to natural historical reasons and recreation load and land ploughing.

  45. Alexeeva N.B. Morphology of some species seeds of the genus Iris L. (Iridaceae) related to the genus systematization //Botanical Journal.2010, Vol. 95, №3. P. 345-350. – The article shows results of the research on seed morphology and micromorphology of seed peel for 10 species of the genus Iris subgenus Iris from 4 sections: Caespitosae(I. ivanovae, I. tigridia), Iris(I. aphylla, I. glaucescens, I. pumila, I. timofejewii), Oncocyclus(I. iberica) and Psammiris (I. arenaria, I. kamelinii, I.potaninii). Seeds have been studied by light and scanning microscopes. Мore than half of the seeds of the species studied have arillus. Primary structure of the seed surface is caused by nature of external tangential cell wall of exotesta which is flat, slightly concave or concave up to complete sinking; the majority of species under consideration have slightly concave tangential walls. The identified features of micromorphology of seeds surfaces allow to make predictions on species groups.

Proceedings of the International Scientific Conference. Pyatigorsk, 2010. P. 10-11. - Crocus scharojanii Rupr. – bulbotuberiferous ephemeroid geophytes with a bright orange perianth. Habitat: Western and Central Caucuses, South-Western Caucuses (North-Western Turkey). The populations were investigated in Karachai-Cherkess, Zelenchuk district in the watershed of the Marukh and B.Zelenchuck Rivers at the footing of Pastukhov’s mount with the gap of 16 years (August 1993 and August 2009). Total area of Crocus scharojanii Rupr. distribution comprises about 5 hectares on the slope of South-Western exposition at the height of 2111-2140 m above the sea level. In 1993 in the given location the grass was used for intensive cattle pasturing and the whole Crocus scharojanii Rupr. Population was very sparced, flowering plants were depressed and didn’t create an aspect. In 2009 there was a dramatic change of plant living state of the high-mountainous species Crocus scharojanii due to easing anthropogenic pressure on phytocenosis. The results of vitality evaluation of Crocus scharojanii in the given location and time period as a reflection of the species adjustment to the changing phytocenosis and ecological environment have been presented.
  47. Alexeeva N. Iris glaucescens Bunge // SIGNA, Molalla (USA), Winter 2010, N 83. P. 4090-4091 - I. glaucescens - Iris glaucescens is bluish because its crescent-bended leaves have bluish bloom. The species is represented by small populations located in Russia, in Southern districts of Western Siberia in the habitat boundary. Beyond Russia boundary it grows in Middle Asia (Kazakhstan) and in the North-West of Mongolia and China. The species is understudied not within the area of growing and is not known for many gardeners. Agrotechnology of Iris glaucescens growing is similar to I. pumila (good drain, sunny place), 2-3 dosings. It winters without cover in St. Petersburg conditions. The species can be used in a stony garden and for border greenery. In situ it has a rich range of colours.

    - Morphology of the Far East species of the genus Iris L. (Iridaceae) relating to sub-genuses: Eremiris (I. oxypetala), Ioniris (I. uniflora), Iris (I. mandshurica, I. vorobievii), Limniris (I. ensata, I. laevigata,I. pseudacorus, I. sanguinea, I. setosa), Tenuifoliae (I.ventricosa) has been studied by scanning microscope. Primary structure of the seed surface is caused by nature of external tangential cell wall of exotesta which is flat, slightly concave or concave up to complete sinking; the majority of species under consideration have slightly concave tangential walls. There have been identified 4 types of primary sculpture of exotesta: faveolate, netted, foveate and plicate whith faveilate being the prevailing one. No clear difference could be made between bearded and beardless irises based on this feature. Primary structure of the seed peel of I. oxypetala and I. ventricosa has been studied for the first time. The key for definition of the Far East species of the genus Iris based on the seed surface has been proposed.

The article provides ID quote, type category, protologue quote, detailed description and biological characteristics of the plant, as well as basics of its cultivation. In Russia, the species is represented by small populations on the borders of the natural habitat in the south regions of the Western Siberia. Outside of Russia, the plant grows in the Middle Asia (Kazakhstan) and in the north-west of Mongolia and China. In the wild, flag prefers sage and bunchgrass steppes, sodic sands, dry stone and crashed stone slopes. It can be cultivated in the rock gardens, as well as for perennial borders as an early spring plant. The plant may attract plant breeders for crossbreeding with other types of dwarf flags due to its draught and salt resistance. The work was performed in the framework of an institutional research project of the Komarov Botanical Institute of the Russian Academy of Sciences, topic 52.5. Collection of live plants of the Komarov Botanical Institute of the Russian Academy of Sciences (history, present condition, development and use prospects).

Diagnostic values of morphological characters in systematic of the section Psammiris of genus Iris are analyzed. Diagnostical value on serial level have features of roots system, root leaves, length of the perianth tube. Features of shape and size of spates are usable for identification of species. The structure of seed surfaces species of Psammiris was studied using scanning electron microscopy. The established features of seed surfaces are stable, and they allow defining groups of the species. Section Psammiris in Russia is represented by 8 species: I. arenaria Waldst.et Kit., I. bloudowii Ledeb., I. humilis Georgi, I. kamelinii Alexeeva, I. mandshurica Maxim., I. potaninii Maxim., I. psammocola Y.
