21. MONOCRANUM, C. Muell. 

 (121.) M. stenodictyon, Kindb. 



Dicranum stenodictyon, Kindb., Bull. Torr. Bot. Club, Vol. XVI. 92. 



Plants densely tufted, about 2 cm. high, nearly eradiculose, Hackish 

 with straw-yellow tops, in color and habit resembling Hypnum sar- 

 mentosum. Leaves appressed when dry, not undulate nor crisped, when 

 moist suberect, straight, nearly flat, from an oblong, below narrowed 

 base, short-acuminate obtuse, crenulate, principally above the middle ; 

 cells thick-walled, not porose, the outer alar, subquadrate brown- 

 yellow, the inner hyaline, the other cells lanceolate or the upper 

 oblong, the apical sometimes oval ; costa simply dentate at the back 

 above, very narrow and only at the base dilated, vanishing in the 

 acumen. Barren. 



This peculiar species differs from our Dicrana principally in the 

 crenulate not properly serrate leaves, which are also very short ; it 

 agrees nearly to Monocranum dicranoides, C. Muell., found near Valdivia, 

 in Chili, having a peristome, differing from the dicranoid type in the 

 teeth being entire, not cleft ; the leaves are long-acuminate.
