 PLANTS JAVANICE RARIORES. 581

marked that it had been referred with a doubt to Cyrtan- dracece by Professor Lindley, in his enumeration of the genera belonging to that family, I should probably have overlooked it altogether, as I had previously done with respect to Ejiithema of Blume, which the author included in Primuhcece, though unquestionably the same genus with my Aikinia, also belonging to Cyrtandracece.

With regard to the genus itself, it may be doubted whether Loxotis and Ghssanthus ought to be generically distinguished merely or chiefly on account of the difference in the number of their antheriferous stamina, especially as they entirely agree in habit, in which there is something peculiar. It is not a little remarkable, that in some of the more minute and less important differences between them, the intermediate structure or connecting link should be found in a species sent by Dr. Schiede from Mexico {Ghs- santhus Meccicana, Br. ined.), and that this should be the only plant belonging to Cyrtandracea hitherto observed in any part of America.

Fig. 8. Upper part of style with the slightly and unequally bilobed stigma. Fig. 9. Capsule with its persistent style, natural size. Fig. 10. The same magnified. Fig. 11. Capsule after bursting, showing the form of one of the parietal placentas. Fig. 12. A placenta separate. Fig. 13. A transverse section of a capsule, show- ing the origin of the placenta and insertion of seeds on both surfaces. Fig. 14. A valve of the capsule with its placenta, from which the seeds have been removed. Fig. 15. A side view of the same. Fig. 16. A seed, with its testa. Fig. 17. A seed, deprived of its testa. Fig. 18.
