Oldenlandia. tetrandria monogynia. 421 



OLDENLANDIA. Schreb. gen. N 205. 



Calyx four-parted, permanent. Coral one petalled, foirr- 

 parted. Capsule inferior, two celled, many seeded. Recepta- 

 cle free, fastened to the partition by the base only. 



Obs. Would it not be better to omit this Gaertnerian part 

 of the generic character, and unite our Indian species of 

 Hedyotis to Oldenlandia *? For except the attachment of their 

 respective receptacles I can find no other mark by which 

 the two genera are to be distinguished, and surely this is too 

 minute and inconspicuous for the travelling Botanist to be 

 able at all times to discover.
