Damrongia is a genus of flowering plants in the Gesneriad family, centered in Thailand and found in southern China, Southeast Asia, and Sumatra. Species were reassigned to it in 2016 in a revision of Loxocarpinae.

Nematanthus is a genus of flowering plants in the family Gesneriaceae. All of its species are endemic to Brazil.Compared to other gesneriads, Nematanthus has leaves that are small, succulent, and hard-surfaced. The plant has a trailing, branching, and spreading habit; it is generally an epiphyte in nature and a hanging-basket plant in cultivation. The flower has fused petals. In some species, the flower has a "pouch" at the bottom. The fancied resemblance of such flowers to a goldfish gives these plants the common name goldfish plant or guppy plant.
Chrysothemis is a genus of flowering plants in the family Gesneriaceae. It includes nine species native to the tropical Americas, ranging from southern Mexico and Cuba through Central America and northern South America to central Brazi
Chrysothemis pulchella (Donn ex Sims) Decne
ระฆังทอง กาสะลองป่า
Chrysothemis pulchella(Donn ex Sims) Decne. has a very broad range of distribution from the Caribbean south to Brazil. It produces a tuber, which allows it to go dormant during the dry season. There are several forms in cultivation that often go under the name 'Copper Leaf', 'Bronze Leaf' or 'Black Flamingo'. All of these may refer to the same plant with darker leaves. Height: 60 cm. The photos below were taken by Nhu Nguyen of a dark-leafed cultivar.
Monophyllaea
Monophyllaea is a genus of plants in the family Gesneriaceae.All the species only have one leaf.
Monophyllaea species are perennial or annual monocarpic herbs (they flower once and then die). The (usually) single stem is fleshy, and most often bears a large single leaf. This is a “macrocotyledon”, the enlarged form of one of the two original cotyledons emerging from the seed. Some species are occasionally caulescent with 3-4 leaves. It is distributed widely in Malesia (from Sumatra to New Guinea and from S. Thailand and Luzon to Java), and grows predominantly on limestone rocks, in shady forests, at cave entrances and below rocks.
With regard to its unifoliate habit (the macrocotyledon reaching a length of 1m in some species) and inflorescence architecture, Monophyllaea is one of the most peculiar genera of Gesneriaceae. Of particular interest is M. singularis(Borneo), with the flowers emerging from the stem, technically the “hypocotyl”, and the midrib of the single leaf/macrocotyldedon (Weber 1987, 1990, Imaichi & al. 2001). In three species (M. caulescens, M. ramosa and M. elongata), several leaves are produced which copy the macrocotyledon in size and shape.

🟢Monophyllaea horsfieldii R.Br.
Monophyllaea horsfieldii R.Br., an unusual herbaceous lithophyte that grows on limestone cliffs in the rainforests from South Thailand and across the Malay Peninsula, is described and illustrated. The species, along with others in the genus, is known for its exceptional morphology, growing only a single large leaf. Monophyllaea horsfieldii also features beautiful, stalked inflorescences that emerge directly from the leaf itself.
