XXVlll EXPLANATION OF THE PLATES. 



Jungermannia and Marchantia is thus established, 

 (109, 278.) 

 Fig. 9. Correa alba Sm. with eight perigynous, unequal fila- 

 ments, and nectareous glands between them, (35, 

 (101.) 

 10. The germen of the same plant enlarged by its greater 

 maturity. The nectaries are divided, and embrace 

 the four two-seeded cocci (86, 109.) 5 which being 

 united form the quadrilocular fruit. That they 

 were originally separate is evident from the infe- 

 rior linear processes, which might be mistaken for 

 collectores, (178, 189,341.) 



11. Flower of Acacia lophanta^ Willd. Monadelphia, 



(131, 187.) 



12. Urceolate corolla of Erica aggregata, with its four- 



lobed margin. Neue Entdeck., 1. 270, (31.) 



13. The sexual parts of the same plant after the corolla 



has been taken away. The four-leaved calyx in- 

 ferior to the germen, (34.) Eight bent filaments, 

 inclosed in the corolla, and between them the nec- 

 tareous glands. Eight bilocular, unarmed, or awn- 

 less anthers, (11, 5Q^ 80.) The pistillum with the 

 four-lobed stigma, (188.) 



14. The germen in particular: there appears a fivefold 



division, as an evidence of the original numerical 

 proportion, (178, 199, 389-) The unripe germen 

 also is multilocular, and it is only when it is fully 

 ripe, that the individual capsules become so united, 

 that their dissepimenta become simple, and extend 

 from the central column, (178, 189, 192.) 



15. Two lipped, ringent corolla of Salvia Boosiana, Jacq. 



(96.) 



16. Two filaments, with processes, %vhich seem to be two 



other abortive filaments, (178.) 



17. Gynobasis, along with the laterally projecting nec- 



tary, and the four caryopscs standing on it. The 

 pistillum between these, with the divided stigma,
