Macrostelia
''Macrostelia'' is a genus in the tribe Hibisceae - in the family Malvaceae. The genus consists of three species: ''M. calyculata'' Hochr., ''M. involucrata'' Hochr., and ''M. laurina'' (Baill.) Hochr. & Humbert. Macrostelias - all native to Madagascar - distinguish themselves from most other genera in Hibisceae by typically bearing flowers with a long corolla tube. Although members of ''Hibiscus'' - an example of one of these other genera - may bear flowers with proximally connate petals, such connation occurs only at the very base of the petals. In the past, ''Macrostelia'' was considered to consist of at least a total of four species. The fourth species - formerly named ''Macrostelia grandifolia'' P.A. Fryxell - is now considered to be under the circumscription of ''Hibiscus''.
