大岩桐属

Gloxinia（学名：Gloxinia），又名红鸟苣苔属，是苦苣苔科下的一个属，只有三個品種，均為開花植物。三個品種有兩個生長於南美洲安第斯山脈，但Gloxinia perennis亦有在中美洲及加勒比地区發現。

Gloxinia perennis是本屬的模式種，亦是本屬最原始的品種。本屬原來有約20個品種，這是基於在1976年的分類而劃分。不過，近年對分子生物學及相關領域對本屬及其相關屬的分析，發現Wiehler當年的分類太廣泛，把很多不相關的品種亦包括進來，因而把這些品種重新分類。

品種 
Gloxinia perennis在中南美洲廣泛分佈。The plant is an herb with large nodding, purple, mint-scented flowers.  It is sometimes known as "Canterbury Bells" (not to be confused with members of the genus Campanula, which go by the same name).  It is cultivated in tropical regions and its original range is unknown.
Gloxinia erinoides (syn. Koellikeria erinoides) occurs from Costa Rica to Bolivia.  The plant is a small herb with tiny white and maroon flowers.  This diminutive plant is notable for having tiny but distinctly coconut-scented flowers and is occasionally cultivated as a houseplant.
Gloxinia xanthophylla (syn. Anodiscus xanthophyllus) occurs in Ecuador and Peru.  The plant is a shrubby herb with small white flowers and is rarely encountered in cultivation.  Unlike the other two species it lacks scaly rhizomes.
