“…The morphological study is based on one specimen collected by Konstantinova in Kenai Peninsula, Alaska, during the field work organized by Dr. Diana Horton in 1992 (Konstantinova, 2021). The specimen is preserved in the herbarium of the Polar-Alpine Botanical Garden Institute, Kirovsk, Russia (KPABG) and a duplicate is stored in the herbarium of the Main Botanical Garden, Moscow (MHA).…”

A morphological and molecular phylogenetic study of a peculiar Solenostoma from Alaska with emarginate to lobed leaves and long purple rhizoids revealed an unknown species. The species is described as Solenostoma alaskanum sp. nov. It is characterized by medium-sized plants, numerous, very long, rigid and sporadically dense, dark purple to dark red-brown rhizoids, mostly short two-lobed or emarginated, rounded-quadrate to oblong leaves, distinct hyalodermis, large granulate oil-bodies and trnL-F and trnG-intron sequences other than in closely related species. The differences from morphologically similar species with bilobed or emarginate leaves and purple rhizoids occurring in Western North America, are discussed. РезюмеМорфологическое и молекулярно-филогенетическое изучение своеобразной Solenostoma с выемчатыми до лопастных листьями и пурпурными ризоидами с Аляски выявило новый вид. Вид характеризуется средними размерами, многочисленными очень длинными и густыми пурпурными до темно-красно-коричневых ризоидами, преобладанием двулопастных или выемчатых листьев, наличием гиалодермиса, крупными зернистыми масляными тельцами и отличными от других видов последовательностями локусов trnL-F и интрона trnG. Рассматриваются отличия от других морфологически похожих видов рода с двулопастными и выемчатыми листьями и пурпурными ризоидами, встречающимися на Западе Северной Америки.

“…During the expedition organized by D. Horton in 1992 to Alaska (Konstantinova, 2021) some specimens were collected, which caused great difficulties with identification. One such specimen contained a very peculiar plant with rounded, oblong, mostly shallowly two-lobed or emarginate leaves and dark purple rhizoids.…”
