FLORA OF SOUTH AMERICA. 35i) 



declinato vix ampliato, limbo plano-patente 5-fido. Gland uke 

 5 lineares. 



The two last genera have moreover the anthers generally 

 free, or less coherent than in the two former, and the stig- 

 matic apex of the style more evidently divided, and Diastema 

 has an inflorescence peculiar to itself. 



There are, however, anomalous species which more or less 

 break through the distinctive characters, especially of the three 

 first genera. Such are Gesneria prasina, or De Candolle's 

 section Prasanthea, probably a distinct genus ; Gloxinia tubi- 

 flora with the corolla of an Achimenes ; Achimenes multijiora 

 with the corolla of a Gloxinia, A'chimenes argyrostigma with 

 the upper lip of the corolla erect, &c. 



*** Calyx involucro diphyllo inclusus. 



The very distinct genus Mitraria is the only one known of 

 this group. 



Tribe 2. Beslerie^e. Ovarium liberum. Semina albu- 

 minosa. 



* Bacca indehiscens. 



Calyx 5-partitus. Corolla tubulosa v. tubuloso-campanu- 

 lata, incurva, fauce valde obliqua, lobis lateralibus cum su- 

 premis alte adnatis incurvis, infimo patente. Filamcnta basi 

 connata. — Columnece vera. 



Calyx 5-partitus. Corolla ventricoso-tubulosa, fauce vix 

 obliqua, labio superiore erecto inferiore patente trilobo. Fi- 

 lamenta basi leviter connata. — Columnece sectio v. genus 

 Ortholoma, Benth. PI. Hartw. 



Calyx 5-partitus. Corolla ventricoso-tubulosa, limbo sub- 

 aequaliter 3-dentato v. 5-partito.— Hypocyrta. 



Calyx 5-fidus v. vix 5-partitus. Corolla tubulosa v. sub- 

 campanulata, limbo subbilabiato brevi. Filamenta libera. 

 Bacca pericarpio tenui vix succosa. — Besleria.* 



^ter., or Trevirana coccinea, Willd.; that species, however, is a true 

 Achimenes, with annular disc, and without the linear glands, or the inflo- 

 rescence of Diastema. 



* De Candolle's doubtful Beslerias, which do not answer to the above 

 character, form probably distinct genera, but are for the most part insuffi- 

 ciently known.
