In Sedum multicaule the divaricating follicles appear slightly 

 connected at the base (as they are in S. pallidum^ M.B.,and others), 

 which has made us very reluctant to propose the new genus Tri- 

 actina for one of the Eastern Himalayan species whose habit 

 agrees in many respects with that of 8. multicaule. But the 

 consolidation of the carpels in Triactina is complete up to their 

 middle ; their number is constantly only 3, which, and its very 

 minute calyx and whorled leaves, together seem to indicate the 

 propriety of keeping it separate. It links the very different and 

 uon-crassulaceous-looking American genus Penthorum with Sedum 

 in a very remarkable manner.
