With more than 60 currently accepted species, Thismia Griffith (1844: 221) is the largest genus of the tribe Thismieae of Dioscoreaceae (sensu APG 2016, or Thismiaceae of other authors). The genus is widely distributed mainly in the tropical and subtropical regions with a concentration of species in Southeast Asia (ca. 30 species) including the Malay Peninsula, Sumatra, Java, Borneo, Thailand and Vietnam. In last decade, many new taxa have been described from Southeast Asia (e.g. Larsen & Averyanov 2007, Chantanaorrapint 2008 2012, Tsukaya & Okada 2012, Dančák et al. 2013, Nuraliev et al. 2014 2015, Truong et al. 2014, Tsukaya et al. 2014, Chantanaorrapint & Sridith 2015, Hroneš et al. 2015, Chantanaorrapint et al. 2016, Sochor et al. 2017). Members of the genus are small mycoheterotrophic herbs with a highly reduced habit and usually grow among leaf litter in shady wet forests.

15. Microchirita luteola C.Puglisi, sp. nov.
Similar to Microchirita tubulosa (Craib) A.Weber & D.J.Middleton but differs in not having spots inside the lateral corolla lobes, having an entire disk (usually dorsally cleft in M. tubulosa), glandular indumentum on the stems (vs. eglandular), and acuminate calyx lobes (vs. usually acute, more rarely slightly acuminate). It is also similar to Microchirita marcanii in the shape of the corolla, but differs in the mixed eglandular and glandular indumentum on many plant parts (eglandular only in M. marcanii (Craib) A.Weber & D.J.Middleton) and the corolla colour pattern (light yellow corolla with a yellow stripe vs. orange corolla with lateral purple spots). Finally, it differs from Microchirita elphinstonia (Craib) A.Weber & D.J.Middleton in having a glandular indumentum and in the larger and much paler yellow corolla.

Four new species of Peperomia (Piperaceae) from Thailand, namely Peperomiaheptaphylla, Peperomia masuthoniana, Peperomiamultisurcula andPeperomia sirindhorniana are described and illustrated. The reinstatement of Peperomia dindygulensis is also proposed with supporting morphological evidence.
Etymology: The specific epithet honours Associate Prof. Sumon Masuthon (1952 – present), Department of Botany, Faculty of Science, Kasetsart University, who encouraged the first author to intensively study the family Piperaceae for the Flora of Thailand project.
Conservation Status. This species is uncommon and only a few specimens have been collected from the border area between Loei and Khon Kaen provinces in northeastern Thailand. The populations are narrowly distributed in an area of karst limestone and not in a protected area. The populations are threatened by farming and deforestation. The status of Peperomia sirindhorniana is assessed as Critically Endangered (CR), according to IUCN (2011) criteria and the authors consider a category of B1b to be appropriate.
Etymology: The specific epithet honours to H.R.H. Princess Maha Chakri Sirindhorn Mahidol who initiated the Plant Genetic Conservation Project to develop the personnel and plant genetics resources for the maintenance of plant varieties, and for the development to be advantageous for farmers and the business sector of Thailand.
Vernacular Name: Rak-Ta-Nil.
Notes:
We discovered some unidentified specimens (T. Smitinand & H. Sleumer 1131 in BKF and L that were collected from Pha Nok Khao, Khon Kaen province, northeastern Thailand. They are similar to Peperomia pellucida in gross morphology but differ in some characters. We have subsequently collected living specimens from a nearby locality and they are easily recognised as a species new to science. The distinguishing characteristics of P. sirindhorniana are its red or reddish petioles and stems, and its bright to dark green leaves when fresh (subcoriaceous when dry) as opposed to pale green (membranous when dried) in P. pellucida. Furthermore, its fruits are larger than P. pellucida and are ovoid with a beaked apex formed from the style and it has densely acute papillae on the fruit surface.
Reinstatement
• Peperomia dindygulensis Miq.
Etymology: The specific epithet refers to Dindygul (the city in the South Indian state of Tamil Nadu) from which the type specimens were collected.

The genus Middletonia in Thailand is revised. We recognise four species, including the newly described Middletonia glebosa C.Puglisi and the resurrected M. reticulata (Barnett) C.Puglisi. A key to the species, full descriptions and proposed conservation assessments are provided.
KEYWORDS: taxonomy, new species, Flora of Thailand

MIDDLETONIA C.Puglisi,
Taxon. 65: 286. 2016.
Type species: Middletonia multiflora (R.Br.) C.Puglisi.
Five species, found in India, Bangladesh, Bhutan, Myanmar, China, Thailand, Laos, Cambodia, Vietnam and Malaysia. Four in Thailand.
Note.— The material from Thailand differs slightly from the Vietnamese material, especially in the leaf shape which is more elongated and with an acute apex in the Thai specimens. As there are rather few specimens from throughout the distribution range, with no floral material from Thailand available for dissection, further collections are necessary to assess whether the Thai and Vietnamese plants belong to one or more species.
2. Middletonia glebosa C.Puglisi, sp. nov.
Similar to Middletonia regularis in having the inflorescences shorter than the leaves and to Middletonia reticulata in the shortly caulescent habit. Differs from both in having a dense indumentum on the adaxial side of the leaf, with glands and eglandular hispid hairs (upperleafsurface glabrescent or minutely glandular in Middletonia regularis, glabrescent in M.reticulata), and in the short, non-twisted, lumpy and irregular fruit (longer, weakly to strongly twisted, smooth and regular in M. regularis and M. reticulata).
Type: Thailand, Sukhothai, Ram Kham Haeng National Park, Khao Luang, alt. 520 m, 11 Oct. 2012, fr., Middleton, Karaket, Suddee & Triboun 5559 (holotype E [E00547434]; isotypes BK, BKF [SN201922]).
Distribution.— Cambodia.
Thailand.— NORTHERN: Sukhothai.
Ecology.— Mixed deciduous forest with bamboo on granite bedrock.
Etymology.— The specific epithet is the Latin adjective glebosus, -a, -um, which means “lumpy” and refers to the peculiar surface of the capsule.
Notes.— In Ram Kham Haeng National Park this species grows in a mixed population with Middletonia reticulata. The two are readily told apart in the field by Middletonia glebosa having softer, paler leaves, a shorter inflorescence, generally slightly smaller flowers, and the curious short, straight, lumpy fruit. The species is known only from Ram Kham Haeng National Park and a single collection made around 150 years ago in Cambodia. The Cambodian collection, placed in Paraboea regularis by Xu et al. (2008), is only in fruit so the identification will need to be verified with flowering material. However, the fruit of this species is rather distinctive.
Thailand.— PENINSULA: Surat Thani, Phangnga; SOUTH-WESTERN: Kanchanaburi.
Ecology.— Lowland evergreen forest on limestone soils.
Note.— The protologue of Paraboea monticolasuggests the flowers to be much larger: “lobes … 6–9 × c. 6.5 mm”. However, none of the material available for this study had lobes longer than 3.3 mm.
Ecology.— Mixed deciduous forest on granite bedrock.
Distribution.— Currently endemic to Thailand but possibly also occurring in Lao PDR and Myanmar.
Thailand.— NORTHERN: Mae Hong Son; Chiang Mai; Lamphun; Lampang; Phrae; Sukhothai.
Note.— This species is resurrected from synonymy of Middletonia multiflora (R.Br.) C.Puglisi from which it differs in the distinctively reticulate venation pattern covered in loose brown indumentum on the lower surface of the leaves, and in the auriculate leaf base. Middletonia multiflora has a denser indumentum on the leaf and the tertiary venation is less densely reticulate and less visible altogether. Middletonia multiflora is widespread along the northern distribution of the genus (from India to Vietnam), but none of the material from Thailand studied can be attributed to M. multiflora.
