fornnng luflexea margins to the valves, Lut the two placeutas remaiQ consolidated iu a single 

 central column ; in Limnophila the margins of the valves are still somewhat inflexed, but a 

 considerable portion of the dissepiment remains entire, detached from the valves, and bear- 

 ing the placentas on its face: the dehiscence in the first two is septicidal, in the third par- 

 tinlly septifragal. The American section Dlamoste of Stemodla has, however, much more 

 the dehiscence of Morgania; and if the latter intermediate genus is to be united with one 

 of the two others, it is rather with Stemodla than with Lhmiophila, The three, however, 

 as now constituted, are natural groups easily recognized.

1. M. floribunda, BentJi. in Mitch. Trov. Aiistr. 384. Stems from a 



lanceolate, entire or with few teeth, from about | in. to above 1 in. long. 

 1 lowers (blue ?) almost sessile or on pedicels usually very short or rarely as 

 long as the calyx, often appearing clustered with small 'leaves in the axils 

 owmg to the partial development of axillary branchlets. Calyx rather larger 

 than in M. glabra and corolla the same size, but much more deeplv cleft, the 

 tube scarcely exceeding the calyx and the lips as long as the tube, the upper 

 one broad truncate and entire as in M. glabra. Capsule shortly acuminate.
