On Petiolar Glands in some Onagraceae. Mr. Thomas Meehan 

 remarked that stipules were unknown in Onagracese, but in Lud- 

 wigia (Isnardia) palustris there were two minute conical gelatin- 

 ous glands that appeared to be stipular. They existed in series of 

 specimens representing the Atlantic and Pacific coast, and from 

 Europe, those from California being larger than in specimens 

 from other locations. They are found in all the species of Lud- 

 wigia and Jussieua that he had been able to examine. In these 

 they appeared petiolar rather than stipular. In the dried speci- 

 mens of Circeea a dark spot indicated the position occupied by 

 the glands in other species. They mostly varied in form and 

 exact position with the species, and only for having been wholly 

 overlooked by describers might have afibrded some good specific 

 characters. The discovery he regarded as interesting, as con- 

 firming the views of those botanists who had brought Turnera- 

 cese^ in which the petiolar glands were known to exist, in close 

 relation with Onagraceae. 



In the specimens of Lxidwigia palustris, dried to exhibit with 

 this communication to the Academy, a single capsule only, cut
