1148. CLYTHRELIA Raf 1815. Lenti- 

 BULARiA Rich. Lind. This family based on 

 Utricularia and Pinguicula, will now contain 20 

 genera. It is a very distinct group, which was 

 very improperly annexed to Primulacea by 

 Jussieu because the fruit is somewhat alike, but 

 there is not a single affinity besides. I put it 

 next to Gratiolides ; but have now my doubts 

 about it, and have been led to consider this fam- 

 ily as rather belonging to Monocotyles and En- 

 dogenous, when it would widely change place 

 and come near the Commelines with irregular 

 corollas. Nay these aquatic plants like many 

 others partake somewhat of the Cellular struc- 

 ture, very evident in the vesicular organization 

 of Utricularia. We have no positive evidence of 

 the seeds being dicotyle and even if they are, 

 they may like Juncus be exogenous notwith- 

 standing. Yet here the calix alone is persis- 

 tent, while the corolla is very deciduous, not at 

 all marcescent. 



1149. Utricularia L. Lentibularia Ad. This 

 aquatic G. of only 9sp. in Linneus has been in- 

 creased to nearly 80 lately, the tropical climates 

 abound with unnoticed sp. Brown found 24 

 new ones in Australia, in North America nearly 

 20 have been detected, see my monograph, Le- 

 conte had already 13, Vahl and Poiret descri-
