 tlendum. Primo aspectu formse tres diatinctse observantnr, a Meissuero in DC. Prod. xiv. 349 et 

 seqq. pro subgeueribus defiiiitae: 1. Eufjrrvilha, porinnthio yMq incuiTo, styli apice stigmatifero in 

 discum obliquitm v. lateraleni dilatato; 2. Conogyne, pcrianthio recto, styli apice conoideo vertice sti-- 

 matifero; et 3. MangU^m, stylo brevi recto infra eonura stigraatiforum fusiformi, sed species sfepe 

 mtermedias et varie commixtae oenurrunt ; in Fl. Austral, species in sectiones 11 distribuuntur, 

 imprimis ad inflorescentiam et pcrianthii formam. Genera sequeutia a variis auetoribus proposita' 

 a Meissnero v. in Fl. Austral, rite ad Grcvilleam revocata sunt.
