minute. Bracts ^ terminal, few pairs, somewliat similar to the 

 leaves, monandrous. 



Obs. — The genus lIi/(/rofjlel/a, Spruce, originally contained 

 three species, Jun(/. la,vifoIla, Hook., Juii(/. niyriocarpa, Carr., 

 and Jii)}(/. ncviccnsu, Carr. ; later, Dr. Spruce, not being satisfied 

 with the position of Jiiu(/. mi/riocarpa in the genus, removed it 

 to an unpublished genus proposed by the late Prof. Lindberg, 

 which Dr. Kaalaas has been kind enough to prepare. 



J//ji(/. jieviceusis having been found in more perfect condition 

 than when Drs. Carrington and Spruce had the opportunity of 

 studying it, proves to be a Mar-sifpcl/a, where it has been placed.

Dioicous, caespitose, flagelliferous, small, pale green to greenish- 

 brown in colour. Stems suberect, almost round, cortical cells 

 14-20, large, inner 6-10 in diameter, smaller remarkably clear 

 with very dark walls ; often much branched at the base, some 

 branches short, flagelliferous, denudate or microphyllous, others 

 assurgent, fastigiate-corymbose below with few and distant leaves, 

 above (chiefly fertile) leaves closer. Kootlets very few or absent, 

 proceeding from the flagella or stem. Leaves transversely inserted, 

 erect, lower ones minute, ovate-subulate, sometimes entire, upper 

 accrescent, subinibricate, oval and oval-lanceolatf-', complicate- 

 oanaliculate and equitant, from \ to ]^ bifid, segments obtuse or 

 acute, often unequal, sometimes only emarginate, very rarely with 

 a third short segment near the middle. Texture lax ; cells rather 

 large, pellucid, leptodernious, rectangular-hexagonal, two to three 

 times as long as broad, walls thin but firm, no thickened angles 

 or trigones. Stipules similar to the leaves, usually a little smaller, 

 below often entire or emarginate. Flowers % terminal on stem 

 or on long or short branches, often repeatedly innovant. Bracts
