DIDYNAMIA— ANGIOSPERMIA. Limosella. 145 



tlie latter finally consists of but one cell ; which is the 

 case in Vcrbascum^ and more or less with many other 

 seed-vessels similarly constructed. No doubt can remain 

 as to the natural order oi^ Limosella ; nor do I perceive 

 the propriety of considering it as belonging to the Precia 

 of Linnaeus, tlie Lysimachice of Jussieu, though those 

 great authorities are against me, and some later ones have 

 traced an affinity to that tribe in the seed-vessel, which 

 is surely altogether that of the Scrophulariiia; of my learn- 

 ed friend Mr. Brown, who appears to have taken the most 

 correct view of the subject. 

 This genus consists of a very few herbaceous, creeping, 

 marsh plants, with simple, entire, stalked, linear or spa- 

 tulate, aggregate leaves, and small, solitary, axillary, pale 

 Jloxvers, on simple naked stalks.
