Medranoa is a genus of flowering plants in the chamomile tribe within the daisy family.[1] It is only found in Texas, USA,[2] and northern Mexico.[3]
Taxonomy edit
The genus name of Medranoa is in honour of Francisco González Medrano (1939–2017),[4] Mexican botanist and lecturer at various Mexican Universities.[5]
The genus was circumscribed by Urbatsch & R.P.Roberts in Sida vol.21 on page 254 in 2004.[1][3]
The following three species of Xylothamia were found to be are related to each other and to Bigelowia and Thurovia.[6]
Due to molecular evidence, these 3 species; Xylothamia pseudobaccharis, Xylothamia parrasana and Xylothamia purpusii were transferred to genus Medranoa in 2007; as M. pseudobaccharis, M. parrasana and M. purpusii, respectively. They joined an originally monotypic species.[3]
Originally plants called Xylothamia johnstonii and Xylothamia palmeri in 1990. They were later moved to genus Neonesomia as N. johnstonii and N. palmeri in 2004.[7] Then they were moved to Medranoa in 2007.[3]
Species edit
There are 5 species accepted by Plants of the World Online;[1]
- Medranoa johnstonii (G.L.Nesom) G.L.Nesom
- Medranoa palmeri (A.Gray) G.L.Nesom
- Medranoa parrasana (S.F.Blake) Urbatsch & R.P.Roberts
- Medranoa pseudobaccharis (S.F.Blake) G.L.Nesom
- Medranoa purpusii (Brandegee) G.L.Nesom
They are found in the Chihuahuan Desert,[3]
Pests edit
They can be affected by Galls, such as Asteromyia gutierreziae on Medranoa palmeri (Texas Desert Goldenrod).[8]
