Codonanthopsis
Codonanthopsis is a genus of flowering plants in the family Gesneriaceae. Its native range is from southern Mexico through tropical America to Bolivia and most of Brazil. Codonanthopsis species are generally trailing epiphytes with pale flowers. Most have a mutualistic relationship with tree-living ants: the plants provide the ants with food, including nectar, and give their nests structure and support, while the ants disperse the plants' seeds. The genus was considerably expanded in 2013 when species were transferred from Codonanthe. Some Codonanthopsis species are cultivated as houseplants, when they may be grown in hanging baskets. Description Codonanthopsis species are subshrubs, generally growing as epiphytes, often in ant gardens (unlike Codonanthe species which never grow in ant gardens). They have stems usually long, occasionally long, with few branches. The stems are usually hanging or creeping, and sometimes produce roots along their length (adventitious roots). The fleshy leaves are variable in form, all the same in some species, or of two sizes in others. Reddish nectaries are often present on the underside of the leaves. The flowers, produced in the upper leaf axils on short pedicels, are either solitary or in groups of a few together, rarely in groups of up to
