DIDYNAMIA— ANGIOSPERMIA. Limosella. 145 



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

 case in Verbascum, and more or less with many other 

 seed-vessels similarly constructed. No doubt can remain 

 as to the natural order of Limosella ; nor do I perceive 

 the propriety of considering it as belonging to the Precipe 

 of Linnaeus, the 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 Scrophularin<^ 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 

 Jlowers, on simple naked stalks.

In muddy spots, where water has stagnated during winter, not 

 very uncommon. 



First noticed in Suffolk, on the Denes at Lowestoft, in 1808, by 

 Mr. R. Brown. 



Annual. July, August. 



Root fibrous, throwing out naked runners, which fix themselves at 

 the ends by fresh fibres, and form new plants. Herb diminutive, 

 quite smooth. Leaves lanceolate, bluntish, erect or spreading, 

 an inch long ; on footstalks twice that length, sheathing at the 

 base. Fl. on shortish, crowded, axillary stalks, about half an 

 inch long, or more, recurved after the blossoms are past. Cor. 

 white or flesh-coloured. Caps, hardly bigger than mustard-seed.
