Grubbia is agenus offlowering plants.[2] It is the sole genus in thefamilyGrubbiaceae.[3] The genus has threespecies, allendemic to theCape Floristic Region of South Africa.[4] They areshrubs that grow to 1.5 m (4.9 ft) tall, with tinyflowers and slender, leatheryleaves.[5] Thefruit is asyncarp.
Grubbia wasnamed byPeter Jonas Bergius in 1767 in a Swedishjournal entitledKongliga Vetenskaps Academiens Handlingar.[6] Thegeneric name honors the SwedishbotanistMichael Grubb.[7]
Grubbia was revised bySherwin Carlquist in 1977.[8]Grubbia gracilis,Grubbia hirsuta, andGrubbia pinifolia had all been recognized, at least by some authors, at speciesrank, but Carlquist treated them assubspecies orvarieties ofGrubbia rosmarinifolia. Some authors had recognized a second genus,Strobilocarpus, in the family Grubbiaceae, but Carlquist assigned its two species,Strobilocarpus rourkei andStrobilocarpus tomentosa toGrubbia.
Molecular phylogeneticstudies have shown thatGrubbia issister toCurtisia, another genus from South Africa.[9] It has been suggested thatGrubbia andCurtisia might be combined into a single family.[10] This was not followed by theAngiosperm Phylogeny Group in theAPG III system of 2009.
