Middletonia is a genus of flowering plants in the family Gesneriaceae. It includes five species native to Asia, ranging from the eastern Himalayas through Indochina to Peninsular Malaysia and southern China.
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.
Most species are herbaceousperennials or subshrubs but a few are woody shrubs or small trees. The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups. As with other members of the Lamialesthe flowers have a (usually) zygomorphic corolla whose petals are fused into a tube and there is no one character that separates a gesneriad from any other member of Lamiales.[4]Gesneriads differ from related families of the Lamiales in having an unusual inflorescence structure, the "pair-flowered cyme", but some gesneriads lack this characteristic, and some other Lamiales (Calceolariaceae and some Scrophulariaceae) share it. The ovary can be superior, half-inferior or fully inferior, and the fruit a dry or fleshy capsule or a berry. The seeds are always small and numerous. Gesneriaceae have traditionally been separated from Scrophulariaceae by having a unilocular rather than bilocular ovary, with parietal rather than axile placentation.
From about 1997 onwards, molecular phylogenetic studies led to extensive changes in the classification of the family Gesneriaceae and its genera, many of which have been re-circumscribed or synonymized. New species are still being discovered, particularly in Asia, and may further change generic boundaries. A consensus phylogeny used to build classifications of the family in 2013 and 2020 is shown below (to the level of tribes). The family Calceolariaceae is shown as the sister to Gesneriaceae.
Paraboea are a genus of flowering plants in the African violet family Gesneriaceae, native to southern China (including Taiwan and Hainan), Assam, Indochina, and Malesia. They were recircumscribed from Boea in 2016.
Twenty species of Paraboea from Thailand
ABSTRACT. Twenty new species of Paraboea are described from Thailand: Paraboea arachnoidea Triboun, Paraboea axillaris Triboun, Paraboea bhumiboliana Triboun & Chuchan, Paraboea doitungensis Triboun & D.J.Middleton, Paraboea eburnea Triboun, Paraboea insularis Triboun, Paraboea lavandulodora Triboun, Paraboea monticola Triboun & D.J.Middleton, Paraboea nana Triboun & Dongkumfu, Paraboea nobilis Triboun & D.J.Middleton, Paraboea peninsularis Triboun & D.J.Middleton, Paraboea phanomensis Triboun & D.J.Middleton, Paraboea quercifolia Triboun, Paraboea rosea Triboun, Paraboea sangwaniae Triboun, Paraboea siamensis Triboun, Paraboea takensis Triboun, Paraboea tenuicalyx Triboun, Paraboea vachareea Triboun & Sonsupab and Paraboea xylocaulis Triboun. Full descriptions and conservation assessments are provided for all taxa.
individuals.Notes. Paraboea arachnoidea is most similar to another new species Paraboea rosea Triboun in its large overall size, the leaves in a rosette, the dense covering of arachnoid hairs on most parts and the dense owers, but it differs in the denser covering of arachnoid hairs on the leaves, elliptic leaves, longer peduncles (18–26 cm long in P. arachnoidea, 10–15 cm in P. rosea), violet corollas and shorter capsules (0.8–1 cm in P. arachnoidea, 1–1.9 cm in P. rosea).

Ornithoboea is a genus of flowering plants belonging to the family Gesneriaceae. Ornithoboea are perennial herbs, with stems curved at base. Leaves are opposite, often (slightly) anisophyllous. Distribution is from southern China southward to the northern part of the Malay Peninsula (China, Malaysia, east Myanmar, Thailand, Vietnam).
The plants grow on rocks, in shaded, humid places and some (possibly all) species are confined to limestone.
A few species, in particular O. arachnoidea (S. China, N. Thailand), are remarkable for the extraordinary similarity of the flowers to orchid flowers.
Codonoboea is a genus of flowering plants in the family Gesneriaceae. It includes 129 species which range from Myanmar and Thailand through northern Malesia (Peninsular Malaysia, Sumatra, Borneo, Sulawesi, the Philippines, and Maluku) to New Guinea. Many of its species were formerly placed in the genus Henckelia.
A revision of Codonoboea (Gesneriaceae: Didymocarpoideae) in Thailand

ABSTRACT. The genus Codonoboea Ridl. (Gesneriaceae: Didymocarpoideae: Trichosporeae: Didymocarpinae) is revised for Thailand. Thirteen species are recognised, one of which, Codonoboea poopathii D.J.Middleton, is new to science and three of which, C. dawnii (Kiew) Kiew, C. oreophila Kiew ex C.L.Lim and C. urticoides (A.Weber) Kiew, are new records for Thailand. Didymocarpus reptans Jack is neotypified; D. hispidus Ridl. var. selangorensis Ridl., D. inaequalis Ridl., D. rugosus Ridl. and D. urticifolius Ridl. are lectotypified; and D. hispidus Ridl.

Microchirita is a genus of flowering plants in the family Gesneriaceae, subfamily Didymocarpoideae.It contains 48 species native to tropical Asia, ranging from the Indian subcontinent to Indochina, southern China, Malaysia and Thailand

Most similar to Microchirita limbata C.Puglisi in the overall shape of the corolla and in colour, but differs in not having a glandular indumentum and in the much longer corolla and larger calyx. – TYPE: Thailand, Loei, Pha Khao, ..., 447 m, 5 November 2014,
Similar to Microchirita involucrata (Craib) Yin Z.Wang and M. rupestris (Ridl.) A.Weber & Rafidah) in having bracteate inflorescences. Differs from both in the bracts being fused only at the base (i.e. not divided as in Microchirita involucrata and not fused into a cup as in M. rupestris), in the dimorphic indumentum of sparse, long eglandular hairs and dense short glandular hairs on the leaf (eglandular indumentum in M. involucrata and M. rupestris), and in the tripartite calyx. It differs further from Microchirita involucrata in the serrate margin of the bracts and from M. rupestris in the much smaller size of the bracts. – TYPE: Thailand, Nan, Song Kwaw, Sakoen, Khao Tham Plakang, 750 m, 3 September 2006, Watthana, S. 2126 (holotype QBG; isotype CMU).

Aeschynanthus
Aeschynanthus is a genus of about 150 species of evergreensubtropical and tropicalplants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno (to be ashamed) and anthos (flower).[2] The common name for some species is lipstick plant, which comes from the appearance of the developing buds emerging from the calyces. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
