“…In the current fern system developed using molecular genetics methods, the representatives of the genera Ceratopteris and Acrostichum exhibit an extremely high degree of relationship (Hasebe et al, 1996;Smith et al, 2006;Schuettpelz et al, 2007;Liu et al, 2008;Schuettpelz, Pryer, 2008;Christenhusz, 2011;Schneider et al, 2013;Zhang et al, 2017). However, the authors of early scientific works on the taxonomy of ferns emphasized the peculiarity of the external morphology of the representatives of Ceratopteris and defined the genus as a monotype that forms an independent family Parkeriaceae Hook.…”

Scanning electron microscopy (SEM) was used to perform a comparative study for four representatives of the subfamily Ceratopteridoideae (J. Sm.) R.M. Tryon from East Asia: Ceratopteris thalictroides Brongn., C. pteridoides (Hook.) Hieron., Acrostichum aureum Linn., and A. speciosum Willd. The analysis of the external morphology of the representatives of Ceratopteridoideae revealed a strong difference between Ceratopteris and Acrostichum. The external morphology of spores of Ceratopteris and Acrostichum exhibited the features characterizing the family Pteridaceae as a whole: tetrahedral spores with a three-ray laesure, from triangular-roundish to roundish, distinct exosporium with a pronounced surface ornamentation and absence of perisporium, the exosporium surface varying from smooth and rough to that covered with large tubercles and roller-like bulges.The external morphology of spores of Acrostichum is quite simple, although among other representatives of the family Pteridaceae, the spores of Ceratopteris have distinctive features: very large equatorial diameter (106-124 µm); spores are almost roundish; distinct cylindrical folds running parallel to the corners of the spore across its extensive distal surface.

“…In the relevant research conducted in 2017 that considers the phylogeny of the subfamily Pteridoideae C. Chr. ex Crabbe, the family Pteridaceae, C. microphylla takes an isolated position in the subfamily system (Zhang et al, 2017). At the same time, the group Cerosora, which includes a single representative of the genus, is closely related to the group of the representatives of Pityrogramma and Gastoniella -a new genus, which comprises three species, previously considered in Anogramma (Gastoniella Li Bing Zhang a. Liang Zhang, gen. nov., Zhang et al, 2017).…”

We used the method of scanning electron microscopy (SEM) to study the representatives of the genus Anogramma from SouthWest Asia and the Himalayas. To confirm the presence of Cerosora microphylla (Hook.) R.M. Tryon in China (hence, the absence of Anogramma microphylla (Hook.) Diels), we revealed the features of external morphology of spores that are not inherent in representatives of the genus Anogramma: absence of an equatorial ridge, roundishtriangular shape of the spores in the proximal-polar and distal-polar positions; absence of roller-like bulges extending upward in the form of ridges along the contour of the distal side of the spore; roller-like folds extending upward in the form of ridges both on the proximal and distal sides of the spore. In addition, one feature revealed for C. microphyllaspherical tubercles between the proximal and distal roller-like folds located along the spore equator-indicates its high species-specificity.

“…Phylogenetic analysis on the base of sequencing of the chloroplast rbcL gene demonstrates that Onychium is closely related to Actiniopteris Link and Pteris L. (Zhang G. et. al., 2005;Dou et al, 2015;Zhang L. et. al., 2017).…”

“…But it is not possible to indicate what the specimens were used in these studies. L. Zhang et al (2017) indicated the number of specimen of O. moupinense var. ipii as "Zhang X. C., 2999 (PE), Chongqing, China", but the correct number is 2699 (not 2999).…”

Summary. The ultrastructure of the spore surface of Onychium ipii Ching (Pteridoideae, Pteridaceae) was investigated by using of scanning electron microscopy. Spores of Onychium ipii are trilete, tetrahedral, with hemispherical distal side and convex proximal one. Equatorial diameter 42.4-48.1 μm, polar axis 35.7-40.6 μm. Distal and proximal sides are separated by an equatorial flange, which protrudes on 4.3-4.8 μm all around the spore. Tubercles of different size form the interrupt "laesura lips" situated on both sides of laesura arms. Proximal side of spore with three stright ridges 3.1-4.5 μm width arranged parallel to spore margins and formed triangle in outline. университет, пр. Ленина, 36, г. Томск, 634050, Россия.

Методом сканирующей электронной микроскопии проведено сравнительное исследование морфологии спор Onychium ipii Ching. Выявлены основные признаки, характерные для спор вида. Споры трехлучевые, тетраэдрические, в проксимально-полярном и дистально-полярном положениях треугольно-округлые, стороны споры слегка выпуклые. В экваториальном положении проксимальная сторона выпуклая, дистальная -полусферическая. Экваториальный диаметр 42,4-48,1 мкм, полярная ось 35,7-40,6 мкм. Прокси-мальная и дистальная стороны разделяются хорошо выраженной экваториальной складкой 4,3-4,8 мкм шир., с выемками в углах споры. Лучи лезуры прямые, с расположенными в ряд по обеим сторонам каждого луча дис-кретными бугорками разного размера. Дистальная сторона споры извилисто-складчатая, с редкими неболь-шими ареолами. Близ экваториальной складки бугорки и складки дистальной стороны сливаются в сплошную складку, располагающуюся вокруг споры параллельно экваториальной.
