XCIV.— LENTIBULARIE^. 



The two genera, of which this order was originally composed, were placed, by Jussieu, 

 among a number of others as allied to his order Lysimachece^ the present Primulacece, In 

 1806, Hoffmansegg and Link separated them to form the type of the present order, under 

 the name of Utricularinae. In 1808, Richard, probably without being aware that he was 

 anticipated, adopted a similar view of their affinities, and published them as a new order, 



under the 



name 

 1810, though aware 

 that time the 



of Lentibulance. ^His less appropriate name was adopted by Brown in 

 of the existence of the other and older one, which he quotes. Since

- - older name has been generally set aside until recently revived by Endlicher 



and Miesner who in this instance stand nearly alone in respecting the rights of priority,* 

 which seems the more remarkable as the genus Lentibularia has been long since reduced 

 to a synonym of Utricularia. 



Tfio family consists of numerous small species of aquatic and marshy herbaceous plants: 

 the former float on the surface by means of numerous small bladders attached to their 

 leaves. As regards the distinction of species this is a very difficult order, especially the 

 genus Utricularia^ the only one found in Southern India, the species of which are numer- 

 ous, and afford few marks of distinction even in the recent state, and when dried some of 

 the best, those derived from the flower, are often either lost or so much impaired by the 

 process as to become of little value. The flowers are usually small, those of U. reticulata 

 being among the largest of the Indian ones. In colour they vary, yellow and various shades 

 of blue^ predominating, but red and white are also occasionally met with. The seed are 

 very mmute, but considerably diversified as regards form and surface, and promise, when 



more attention has been given to them, to furnish useful specific characters.
