Desmodium flexuosum Wall. ex Benth. was validly published. Five original specimens were examined at BM, G, K, and K-W by authors and one duplicate was recorded by Ohashi (1973). All specimens are from the same gathering and in a perfect condition. A specimen kept at K-W (K 001121777) is selected here as the lectotype because it is well preserved in Wallich’s collection at Kew.	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.

This collection is later found in A and E herbaria. A duplicate at E is mounted on single herbarium sheet with two labels, a determination slip and barcode label. This duplicate is selected here as the lectotype, whereas another one kept at A is a photocopy of specimen from E. On the upper left of sheet is consisted of a small pocket with leaf and fruit inside which are presumed to be fragments of E specimen. According to article 8.3, Ex. 8 of ICN (Turland et al., 2018), fragment that is removed from type and conserved at another herbarium or institution should be isotype (or isolectotype in this case).	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.

03BD87AEFF93FF997D8F659D627CFEF8.taxon	discussion	Notes: — This species is previously considered as a member of genus Uraria. It is treated here as a member of Sohmaea because it has a straight pod when mature. Desmodium hispidum Franch. is presumably described from a single specimen. Holotype of this name is kept at P, whereas its fragments of leaflet and inflorescence along with a photograph of holotype itself are kept at A. These fragments should be an isotype in accordance with Art. 8.3, Ex. 8 of ICN (Turland et al., 2018).	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.

03BD87AEFF9CFF987D8F605460D4FE68.taxon	discussion	Notes: — This subspecies differs from the typical subspecies in a number of leaflets and upper tooth of calyx. Other morphological characters are very similar to each, especially inflorescence type, calyx, corolla, staminal tube, fruit, and seed. This taxon is therefore treated under Sohmaea laxiflora.	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.

There are two syntype duplicates of D. macrophyllum Desv. kept at P. The samples of each duplicate were mixed between S. laxiflora and Ototropis megaphylla (Zoll. & Moritzi) H. Ohashi & K. Ohashi. The first duplicate (P 02937969) consisted of two leaves of O. megaphylla, mounted on the left side of the sheet. A leaf and inflorescence with flowers and young fruits of S. laxiflora are on the middle and right side of the sheet. The second duplicate (P 02937970) consisted of a twig with three leaves and inflorescence (with flowers and young fruits) of O. megaphylla, covering the most part of the sheet, while inflorescence with flowers and young fruits of S. laxiflora are mounted on the right side.	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.

03BD87AEFF98FF9C7D8F659361CFFDB4.taxon	discussion	Notes: — This species is similar to Sohmaea teres but it is differed by having longer petiole and longer and larger pod article. The protologue of Desmodium ormocarpoides DC. var. velutina Prain was based on two specimens originated from Malaysia, Ridley 2605 (SING) and Ridley 7295 (SING). The first one is selected here as a lectotype because it has more perfect condition than the latter.	en	Saisorn, Witsanu, Chantaranothai, Pranom (2022): A taxonomic revision of two genera, Pleurolobus and Sohmaea (Leguminosae) in Thailand and Indo-China.
