pro organis femineis optimo jure haberi poterunt. Neque obstaret declarata eorum flexilitas, quae 
nil facile aliud nisi parietum teneritatem involved et plantis ex merit fabric^ vesiculari succres- 
centibus, vix quidquam officiet. Si igitur Vaseula Antherae polliniferae porro dici volunt, acervuli 
aut frustra creati sunt, aut verior usus illis adsignandus est eo, quem diximus. Neque enim per 
glomerulos istos, qui nunquam solvuntur, neque per contenta eorum, quae citb contabescunt, planta 
propagabitur, sicuti experiments cautissimc captis supra evicimus.” The same author has remarked, 
that the calyptra, or, as he considered it, the corolla, instead of opening at the extremity for the 
emission of the capsule, is carried up upon it by the elongation of the peduncle. “ Cbm etiam 
corolla, ut vidimus, radicata sit, ideb interdhm accidit, subeunte velocius humore aut in frondem, 
aut pedunculum egressum parantem, aut ubi frondis margines earn non satis arctb firmant: ut corolla 
ex parte radicosa frondis solvatur et cum pedunculo, vaginae instar, attollatur ; eum autem ob pondus 
adpensum ita impediat, ut rarb notabilem altitudinem nancisci tunc possit.” leones, p. 139. 
Dillenius has quoted doubtfully the Hepalicoides palustris Cichorii crispifoliis, Vaillant, Bot. 
Par. p. 100. t. 19. /. 4. as a synonym to the present species. The situation of the fructification, 
however, in that plant, and the figure of the capsule, prove that it belongs rather to J. epiphylla, 
:is Schmidel suspects, and indeed that it. can be considered only as a variety of it. 
Upon the under side of the fronds of some of the plants which grew under water, were 
innumerable granules, intermixed with many oblong pellucid bodies, which are represented at 
f. 9. and arc, in all probability, some undescribed animalcules.
