Although this moss is generally referred to A . stellatum, it is really far 

 more related to the last species, and just as nerveless leaves are found on the 

 latter, so we occasionally find on the present leaves faintly nerved half- 

 way. The multipinnate trailing stems closely clasping the stones is quite 

 characteristic, and with the highly attenuated leaves and perichsetial bracts, 

 give it more than a varietal distinction.

Amblystegium stellatum Lindb. Muse, scand. 32 (1879). 



Dioicous ; robust, erect or decumbent, in lax soft, yellowish-green 

 tufts. Stems subdichotomous, with erect fastigiate branches. Leaves 

 crowded, squarrose, from an erect cordate base, subdecurrent at the 

 basal angles, ovato-lanceolate, acutely acuminate, entire, scariose, 

 nerveless or with two very short faint nerves ; cells very narrow, linear, 

 8 — 10 times long as broad, the basal angular cells rectangular, 

 incrassate, pellucid or orange. Perichaetium subvaginant, the lower 

 bracts recurved from middle, inner erect, sulcate, with a filiform 

 apiculus. Capsule on a red seta, incurved cernuous, subcylindric.
