section at the end. Callitriche, Lemna, and even Pistia, 

 were proposed to be brought hither ; with Saururus and 

 Aponogeton. 



'. The qualities of the Inundates are very obscure. 

 These plants are mostly inodorous, except a fishy scent 

 in some ; nor have they any particular taste ; hence they 

 are not used medicinally." 



This order is out of its place with respect to the ar- 

 rangement by the cotyledons, of which Linnaeus seems 

 aware, from the remarks subjoined to it, in his lectures, 

 concerning that principle. To these we shall hereafter 

 refer. 



Order 16. Calyci florae. This consists of Osyris, 

 Trophis, Hippoph'de and Elceagnus. No observation re- 

 lative to it is given in the lectures, except that these ge- 

 nera are removed elsewhere. A manuscript note before 

 us indicates a suspicion of its relationship to the 6th sec- 

 tion of the Holeracea. Linnaeus sometimes referred Me- 

 mecylon to one of these orders, sometimes to the other, 

 but finally to his 18th ; we should rather presume it be- 

 longs to the 1 9th notwithstanding the definite number of 

 the stamens, which caused Jussieu to range this genus 

 with the Linn-dean Calycmithema ; see the next order. 



Order 17. Calycanthem;e. "The title of this older 

 is precisely synonymous with the last, and is applicable 

 in a different manner to the different genera of which the 

 present consists. In those whose germen is inferior, the 

 calyx bears the flower and enfolds the germen ; in those 

 where the latter is superior, it is unconnected with the 

 calyx, into which the stamens are, in that case, inserted, 

 like the Senticoscz and Pomacea, not into the receptacle. 

 The germen is inferior in Epilobium, Oenothera, Gaura, 

 Jussieea, Ludwigia and Isnarda, as well as in Mentzelia 

 and Loosa" (or Luasa) ; "in the rest, Ammannia, Gris- 

 Itea, Glaux, Peplis, Frankenia, Lythrum, Melastoma, Os- 

 beclcia, and Rhexia, it is superior. Some genera have 

 four, others five or six petals. Glaux and Isnarda have 

 none. Ammannia and Peplis have occasionally petals,
