Type species is Grubbia rosmarinifolia P.J.Bergius . Synonyms for Grubbia P.J.Bergius are: Ophira Burm. ex L. , Strobilocarpus Klotzsch . The Grubbiaceae family was established in 1841 by Stephan Ladislaus Endlicher in Carl Daniel Friedrich Meisner : Plantarum vascularium genera secundum ordines .... , 1, p. 323, 2, p. 239. The Grubbiaceae Endl family . ex Meisn. nom. cons. was previously included in the order Ericales and is now part of the Cornales .
There are three species in the genus Grubbia :
-
Grubbia rosmarinifolia P.J.Bergius : There are three subspecies:
- Grubbia rosmarinifolia subsp. gracilis (TMSalter) Carlquist : It occurs in the Western Cape .
- Grubbia rosmarinifolia subsp. hirsuta (E.Mey. ex DC.) Carlquist : It occurs in the Western Cape.
-
Grubbia rosmarinifolia subsp. rosmarinifolia : There are two varieties:
- Grubbia rosmarinifolia subsp. rosmarinifolia var. pinifolia (Sond.) Carlquist : It occurs in the Western Cape.
- Grubbia rosmarinifolia subsp. rosmarinifolia var. rosmarinifolia : It occurs in the Western and Eastern Cape .
- Grubbia rourkei Carlquist : This rare species thrives on moist sandstone slopes only on the Kogelberg at higher altitudes in the Western Cape. Less than five sites are known, all of which are in a protected area.
