Abstract. Saensouk S, Boonma T, Thomudtha A, Thomudtha P, Saensouk P. 2021. Short Communication: Curcuma wanenlueanga (Zingiberaceae), a new species of subgenus Curcuma from Thailand. Biodiversitas 22: 2988-2994. Curcuma wanenlueanga Saensouk, Thomudtha & Boonma, a new species of Curcuma subgenus Curcuma (Zingiberaceae) from Thailand was described with detailed illustrations, and photographs. The dominant morphological description is terminal inflorescence, leaf adaxially green with reddish-purple along the midrib, leaf-sheath with reddish-brown tinge. Moreover, the color and smell rhizome of C. wanenlueanga has yellow with a darker core internally. It is distributed in Mae Hong Son Province, Northern Thailand, and cultivated throughout the country, i.e. Nakhon Nayok, Maha Sarakham, Chiang Mai, Tak, Chantaburi, Suratthani, and Kanchanaburi Provinces. It is used as Thai traditional medicinal. It grows in in sandy loam soil and well-drained in the mixed-deciduous forest, at elevation 700-900 m asl. It is accompanied by a revised key to 26 species of Curcuma subgenus Curcuma from Thailand.

Abstract. Saensouk P, Boonma T, Saensouk S. 2022. Curcuma nakhonphanomensis (Zingiberaceae), a new species from the lower Mekong River basin, northeastern Thailand. Biodiversitas 23: 6040-6048. Curcuma nakhonphanomensis Boonma, Saensouk & P. Saensouk sp. nov. (Zingiberaceae: Zingibereae) was distributed in Nakhon Phanom Province, northeastern Thailand. The morphological characteristic of this species makes it fall into Curcuma subgenus Ecomata, due to the presence of epigynous glands, lack of coma bracts and bracts fused only at the base, and production of open-form of flowers. This plant did not match any existing species after careful morphological examination and comparison of all allied species in the genus Curcuma, especially in subgenus Ecomata. Therefore, we described it here as a new species to science in the name of Curcuma nakhonphanomensis Boonma, Saensouk & P. Saensouk. The specific epithet is named according to the province's name of the type locality. The morphological characteristics description, illustrations, vernacular name, ecology, phenology, distribution, utilization, conservation status, and map of distribution are present. The comparison table of the new species and its allies species, including a revised key to 41 species of Curcuma subgenus Ecomata is provided.

Abstract. Saensouk P, Boonma T, Saensouk S. 2022. Curcuma pulcherrima (Zingiberaceae), a new rare species of Curcuma subgen. Ecomata from eastern Thailand. Biodiversitas 23: 6635-6644. Curcuma pulcherrima Boonma, Saensouk & P. Saensouk sp. nov. (Zingiberaceae: Zingibereae, belonging to Curcuma subgenus Ecomata) distributed in Ubon Ratchathani Province, the eastern part of Thailand. The morphological characteristic of this species causes it to fall into Curcuma subgenus Ecomata due to the presence of epigynous glands, lack of coma bracts, bracts fused only at the base, and production of open-form flowers. Furthermore, this species is similar to Curcuma pierreana Gagnep., due to its similar color flowers with a pink tinge, but lighter (vs. C. pierreana maroon tip), and similar to Curcuma siamensis Saensouk & Boonma due to its characteristics of the anther and spurs. Nevertheless, after careful morphological examination and comparison of all allied species in the Curcuma genus, especially in subgenus Ecomata, it was found that this plant did not match any existing species. Therefore, we describe it here as a new species to science with the name of Curcuma pulcherrima, according to this species's very beautiful inflorescences and flowers. In contrast, its morphological characteristics description, illustrations, vernacular name, ecology, phenology, distribution, utilization, conservation status, map of distribution, and comparison table of the new species and its ally species, including a revised key to the species of Curcuma subgenus Ecomata are provided.
