Stenolejeunea Schust. was segregated (Schuster 1957) from Taxilejeunea to which there is a resemblance in the typically acute/acuminate leaves; small lobules; lejeuneoid gynoecial innovations. It is remote from Taxilejeunea in the proclivity for asexual reproduction via linear thalloid “gemmae;” the much simpler stem anatomy, with fewer medullary cell rows and rather weakly enlarged cortical cells; the ― mostly ― generalized gynoecial orientation, rarely with strong differentiation of uniseriate, repeated gynoecial innovations.
Although mostly Indomalayan, isolated species (S. acuminata) occur as far as northernmost New Zealand. Some seven species are recognized, S. acuminata Schust. and S. fissistipula Schust. are new.
