“…Pods are dehiscent or indehiscent with one to several articles as well as one to several seeds. Seeds are reniform, rectangular, or quadrangular (e.g., Ohashi 1973Ohashi , 1982Ohashi , 2004aOhashi , 2004bNiyomdham 1994;Pedley 1999; Saisorn and Chantaranothai 2013, 2015Lima et al 2014;Leeratiwong et al 2017;Satthaphorn et al 2018;Tokaew et al 2020).…”

Abstract. Saisorn W, Suddee S. 2023. Seed micromorphology of tribe Desmodieae (subfamily Papilionoideae, family Leguminosae) from Thailand with its taxonomic implications. Biodiversitas 24: 5572-5585. The seed micromorphology of 21 genera and 58 species of the tribe Desmodieae in Thailand was studied. The result showed that the shape of the seed can be ellipsoid or transversely ellipsoid, irregular, oblongoid, quadrangular, rectangular, reniform, rhomboid, subcircular, and triangular. An oblongoid shape is restricted to the genus Sohmaea; the seeds’ length, width, and thickness are 0.94-5.93 mm, 0.78-3.65 mm, and 0.39-1.92 mm, respectively. The testa color can be light green to green, yellow, light to dark brown, or black. Testa patterns can be classified into nine types: colliculate, colliculate-rugulate, fissured, pitted, reticulate, reticulate-reticulate, reticulate-rugulate, rugulate, and smooth. The rim-arillate aril can be thin, thick, or well-developed. This tribe is classified into three groups based on aril types. Group I: a thin rim-arillate type is restricted to Akschindlium godefroyanum. Group II: a thick rim-arillate type is found on the seeds of the most studied plants. Group III: a well-developed rim-arillate type is a taxonomic characteristic of Codariocalyx. The overall shape of the rim-arillate aril is subcircular, circular, subcircular-elliptic, elliptic, elliptic-oblong, and oblong. An oblong shape of the rim-arillate aril is a unique character for Grona heterophylla compared to other species within Grona.

“…Twelve species of Dendrobium were observed and D. strongyanthum, a species belongs to section Stachyobium. Tokaew and Chantaranothai (2009) reported a result from a 2 years preliminary study of Orchidaceae in Nam Nao National Pak, Phetchabun Province. Fifty-six genera and 129 species were enumerated.…”

Taxonomic revision of Dendrobium Sw. section Stachyobium Lindl. in Thailand? has been conducted from 2015?2018 based on natural habitats observation in Thailand as well as various herbaria visits, i.e. BCU, BK, BKF, BM, C, CMUB, E, K, KKU and QBG. Key to species, taxonomic descriptions, ecological data, illustrations and geographical distribution of all taxa are provided. Twenty four taxa with including 21 species and 3 varieties were recognized. Among these, two species namely Dendrobium chiangdaoense and D. obchantiae are new to Thailand and two species viz. Dendrobium sp.2?and Dendrobium sp.3?are being proposed as new species. Besides, Dendrobium sp.1?is also being proposed as new variety. Plant status was investigated, 7 species, i.e. D. confinale, D. dixonianum, D. elliottianum, D. garrettii, D. gregulus, D. mucronatum and D. proteranthum are endemic to Thailand. In addition, 6 species viz. D. cuspidatum, D. denudans, D. kanburiense, D. peguanum, D. perpaulum and D. strongylanthum are also rare species. One taxon namely D. delacourii is reduced from species to the rank of variety under the name D. venustum var. delacourii Promm., Kidyoo
