Asplenium sarelii var. altajense Kom. in Acta Jard. Bot. Petrop. 16: 150. 1916.
Plants 10-12 cm tall. Rhizomes short and erect, apexes densely covered with scales; the scales lanceolate, black, bitly polished, entire. Fronds clustered; stipes 3-3.5 cm long, upper sides longitudinal-valleculate, lower parts black and spasely covered with scales, upper parts and rachises all greyish-green, subsmooth; laminae lanceolate, 8-9 x 2-2.5 cm, apexes acuminate, to base almostly unnarrowed, bipinnate; pinnae 10-11 pairs, lower ones opposite, up alternate, short stalked, mid pinnae ca 11 x 8-10 mm, triangular-ovate, apexes acute, bases asymmetrical, acroscopic truncate basiscopic cuneate, 1-pinnate; pinnules 2-3 pairs, anadromous, basel acroscopic one piece bigest, 4-5 x 2-4 mm, subovate, apexes rounded, bases cuneate, bitly combined with rachillae and decurrent, margins serrate, the serrations sharp at tops. Veins obscure, flabellatly dichotomous-branching, one pair of pinnules on pinnal bases subpinnate, prolongated to serrations, but unreached to margins. Fronds papyraceous, after dry greyish-green. Sori linear-elliptic, 1-2 mm long, darkkish-brown, 2-4 per pinnule on pinnal bases, 1 on each upper pinnule, after maturity spreading all over under surfaces of pinnule; indusia linear-elliptic, greyish-green, thin-membranous, and entire, opening to main veins or rachillae.
In dry crevices of among rocks; 2300-2500 m.; N. E. Xijiang (aertai mountain) [ Mongolia and Russia].
This species distributes only in Altai mountain on bounadary line of China, Mongolia and Russia, its disributioanl region is very narrow. Its shape is most similar to A. nesii Christ, but marginel serrations of pinnule sharp at tops.

北京铁角蕨bei jin tie jiao jue
Asplenium sepulchrale Hook. & Bak.; A. abbreviatum Makino; A. sarelii var. pekinense C. Chr.
Plants 8-20 cm tall. Rhizomes short and erect, apexes densely covered with scales; the scales lanceolate, black, bitly polished, entire or bitly undulate. Fronds clustred; stipes 2-4 cm long, greenish, lower parts sparsely scales, up sparsely covered with black fibrous small scales; laminae lanceolate, 6-12 x 2-3 cm, apexes acuminate, bases bitly narrowed, bipinnate or tripinnatifid; pinnae 9-11 pairs, lower pinnae bitly shortened, opposite, apexes acute, bases asymmetrical, acroscopic truncate, basiscopic cuneate, 1-pinnate; pinnules 2-3 pairs, alternate, anadromous, basel one piece of pinnule bigest, elliptic, 5-6 x 2-3 mm, apex subrounded, bases cuneate and bitly combined with rachillae, decurrent, magins pinnatipartite; segments 3-4 pieces, ligulate or linear, 1-2 mm long, apexes roundly truncate and 2-3 sharp small dentatate, both lateral sides entire; other pinnules smaller, unparted. Veins obvious, upper sides raised, veinlets flabellately dichotomous branching, prologated tops of serrations, but unreached to margins. Fronds firm-herbaceous, after dry greyish-green or darkkish-green; rachises and rachillae same colour with stipe, both lateral sides linear winged, lower parts sparsely covered with black fibrous smaller scales, up smooth. Sori subelliptic, 1-2 mm long, 1-2 on per pinnule ( 2-4 on per basel one pir of pinnules), located at middle of pinnules after maturity darkkish-brown, usually spreading all over under surfaces of pinnules; indusia subelliptic, glaucous, membranous and entire, opening to main veins or rachillae and persistent. Chromosome 2n = 144.
On rocks or in crevices among rocks; 380-3900 m.; Fujiang, S. E. Gansu, N. Guangdon, Guangxi, W. and N.E Guizhou, Hebei, Henan, Hubei, H unan, Jiangsu, Nei Mongol, Ningxia, S. Shaanxi, Shandong, Shanxi, Taiwan, Yunnan and Zhejiang [ Japan and Korea]. Specimen of type collected from Beijing
The shape of this species is similar to A. sarelii Hook., but lamina narrower, lanceolate, firm-herbaceous, basel one pair of pinnae bitly shortened, segment ligulate or linear, apex 2-3 sharp dentaiculate. But frond shapes are much varied in defferent ecologies, it is easy confused with A. sarelii Hook. So must pay more attention in detemination.
определили как иркутский?
Не слишком ли этот эталон "монотипен"? Совсем недавно у Ириса русского Вы показывали совсем иные позиции 
И даже настаивали относить растения, котрые не вписывались в диагноз именно к этому виду. А тут? Степень раскрытости цветка и верхний лист - очень непоказательны. Это вижу на массовом сибирском материале. Ну хорошо, в следующем сезоне буду специально для Вас фотографировать растения с мелкими листьями, длинными цветоносами и полураскрытыми цветками! 
В Саянах - там где сибирского нет.
