 V. axillarem dispositi. Bractea (interdum foliacea) sub pedunculo ei baud raro plus

 V. sub cj'iuula sjepissime 2 oppositse, liberse v. cum bractea in cupulam connatse, v. rarius

 apeciebus conspicui, in plerisque parri, interdum minuti. 



Species vix 220, per regiones tropicas temperatasque utriusque orbis latissime dispersee. Genera 

 plurima hie recepta, praesertim e tribu Osyndearum, oligotypica, ssepe inter se characteribus parvse 

 valoris separata, a botanicis tamen libenter admissa, seepeque patria bene limitata. 



Ordo Loranthaceis valde affinis iisque a Baillono jungitur, sed bene distinctus videtur, imprimis 

 ovarii struetura. Etiam Olacinds pluribus notis aecedit, sed perianthium constanter simplex. 

 Tribus Anihobolearum, fere medium tenet inter Osyrideas et O^nlicas Olavimaruai, et e sententia 

 botanicorum uonnuUorum his adsociandus.
