gracile, of equal width throughout, and from the 

 convexity of the leaves looking like strings of small 

 beads. These have a silky lustre, and are usually 

 of a bright pink or claret colour, but sometimes 

 pale green. The leaves are vertical, unsymmetri- 

 cal, cordate, broader than long, very convex, con- 

 duplicate, gibbous posteriorly, with the. margin 

 infiexed and tumid, bicornute, the ventral tooth 

 not continuous with the border, but arising at 

 some distance within it, segments long and curved 

 liked the horns of an ox. The axillary leaves are 

 cordate-lanceolate, and have only one tooth, while 

 in the perichaetial leaves there are two shorter 

 dentate segments. The texture is thin and silky, 

 the areolse quadrate, discrete, surrounded by a 

 pellucid border.
