LYTHRAEIACEM. 



|_.,....,....^., ....... 



^^etramerous and tetrandrous, with four petals, inserted in the hollows 

 between the sepals. In U. rejpens^^ an Abyssinian species, the petals 

 are smalL and the dimerous gynaecium, analogous to that of 

 Aminannia, is surrounded by a very small annular disk, with very 

 slightly marked lobes. In the Indian species, B. Wallichii^ of which 

 the genus Hydrolytlirum^ has been made, the petals are larger, ex- 

 serted, and the lobes of the hypogynous disk, eight in number, are 

 much more distinct. These differences, otherwise of little importance, 

 serve to distinguish two sections in this genus, which is composed 

 of aquatic herbs, like MijriojpJiyllum^ which they resemble in habit, 

 submerged, verticillate, linear leaves, with flowers in terminal 

 clusters, and accompanied each by two lateral bracteoles which may 

 be more or less raised on their pedicel. 



Adanson* clearly pointed out, in 1763, in what respects the 

 Salicaria family resembled the Myrtle, differing from it in the 

 situation of the gynsecium. He even placed in it Bceckea, of the 

 Myrtacece, A. L. de Jussieu^ republished the family nearly as 

 Adanson conceived it, adding Acisanthera, of the MelastomacecBj 

 and Glaux, of the Frimulaceoe, Later^ he substituted for the name 

 Salicarice ^ that of Lythrarieoe.^ A. P. de Candolle ^ included in it 

 twenty- seven genera, of which only thirteen are now retained as 

 distinct. Lindley ^^ first gave the name Lythracew, Eentham and 

 Hooker, ^^ resuming the name Lythrariece^ admit thirty genera in 

 this group, four of which are abnormal, viz. Funica, which we have 

 restored to the Myrtacece ] ^^ Axinandra, which we consider rather
