 what Haronga is to Vismia.

 three-fourths of the family and distributed among a great number of 



Syperieum hyrclnum.

genera,^ have, with the general characters of Vismia and the neigh- 

 bouring genera, some particular traits which have served to distin- 

 guish a tribe of Hypericece. These are : 

 petals internally glabrous and without 

 appendages; a fruit dehiscing at the 

 interlocular partitions or placenta ; 

 and seeds not winged, the embryo of 

 which, straight or curved, has cotyle- 

 dons ordinarily longer than the radicle. 

 In certain species with rather large 

 flowers, cultivated in our gardens, and 

 of which the genus Eremanthe "^ (fig. 

 344, 345) has been made, the flowers are formed like those of Vismia^
