PI. CXXVII.f. I.,8. Trifacial cells (spores) detached from the 

 same. 



„ f. I. ,9, 10. Fully developed secondary capsule : con- 

 taining 3 masses in which the spores are 

 imbedded. 



PI. CXIX. f. VII. ,6. Secondary capsules, surface view. 

 „ f. VII. ,c. Masses of the same. 

 „ f. VI I., a. A mass detached. 



SALVINIA VERTICILLATA. 



(Development of the Organs, (Ovula,) and of the indefinite mass-con- 

 taining secondary capsules and their contents, trifacial cells, 

 (or spores.) 



PI. CXXV. f. II. ,2. Apex of a reproductive-organ-bearing axis 

 with one somewhat developed ovulum, and 

 one in a much earlier state, i. e. before the 

 appearauce even of the tegument. Both, 

 from their situation, would have contained 

 the spherical mass-containing secondary 

 capsules. 



„ f. I.,7. A young organ (ovulum) under pressure, it 

 is the small one of. PI. CXXV. Fig. l.,6. 



PI. CXXIV. f. II., a. Another rather more advanced. 



PI. CXXV. f. I. ,6. An organ (ovulum) in its perfect state, with 

 a much younger one (CXXV. f. 1,7,) at its 

 base. The supposed fecundating matter 

 shewn in application to the foramen. 



PL CXXIII. f. IV.,9. 11. An organ much less advanced: 9 is a 

 longitudinal section. 

 „ f. II.,5. Another in its perfect state : the jointed ob- 

 tuse filaments are what I take to be the 

 male organs. The supposed fecundating 

 matter shewn in contact with the foramen. 

 It was also noted to have appeared to fill 

 the space in the organ between the nucleus 

 and the foramen. 



PL CXXV. f. III., 2. Young capsule under pressure to shew the 

 nucleus, now a mass of young secondary 

 capsules.
