03E7065CFFEED539FCDEFE52FB81F8D7.taxon	discussion	This transference adds a second species to Parryella, until now conformed by P. filifolia, and reduces from four to three the number of species of Errazurizia, namely E. benthamii, E. megacarpa and E. multifoliolata (Clos) I. M. Johnst. 3. Psorothamnus is paraphyletic, with species falling into two non-sister clades. One of the Psorothamnus subclades, including the type species of the genus (P. emoryi), results sister to Dalea + Marina, a result that receives the highest (100 %) bootstrap value in the partitioned ITS and the matK / trnK analyses, and the combined ITS + matK / trnK dataset. Altogether, this trigeneric assemblage is recovered as sister to a second Psorothamnus subclade with P. arborescens, P. fremontii, P. kingii, P. schottii, and P. spinosus. The bootstrap values that support the latter subclade range from 99 % in the ITS-based analysis to 100 % in the matK / trnK and the combined ITS + matK / trnK analysis. All these species are former members of Psorodendron, a genus described as such in 1919 based on the type species P. johnsonii (= P. fremontii), making imperative its reinstatement. The genus Psorodendron was proposed originally by Rydberg (1919) as distinct from Psorothamnus based on the presence of pedicellate flowers and exserted pods in the former, versus sessile flowers and inserted pods in the latter. An updated description of the genus is here provided, based on all the species assigned to it, and described by Rydberg (1919, 1928 a, 1928 b), and Barneby (1977, under Psorothamnus sect. Capnodendron Barneby, P. sect. Xylodalea (S. Wats.) Barneby, and P. sect. Winnemucca Barneby).	en	Urrego, Paola Piñeros, Suárez-Barón, Harold, Pabón-Mora, Natalia, González, Favio (2023): Reinstatement of the genus Psorodendron and related systematic novelties as revealed from phylogenetic analyses of the tribe Amorpheae (Leguminosae, Papilionoideae).

03E7065CFFEED538FCDEF892FB68FB3E.taxon	discussion	Stoloniferous herbs, shrubs or trees to 7 (- 10) m tall. Branches often spinescent; stems glabrous or sparsely strigulose or vestured with ascending, appressed indument. Leaves pinnate or simple, caducous or persistent at anthesis. Inflorescences loosely racemose or spicate, the axis becoming spiniform during or after blooming. Flowers subtended by a deciduous bract and two small subulate bracteoles at the base of the short pedicels. Petals glabrous, with or without glands. Apex of the connective with or without a gland. Ovules 2 - 7 per ovary. Pods to 1 cm long, inserted to exserted. Psorodendron, as reinstated here, comprises five species widespread in desert basins of Arizona, Baja California, California, Nevada, and Utah (United States). Full synonymy of all five species (based on Barneby, 1977) is given below; names marked with asterisk correspond to Psorodendron binomials treated under the synonymy of Psorothamnus spp. by Barneby (1977).	en	Urrego, Paola Piñeros, Suárez-Barón, Harold, Pabón-Mora, Natalia, González, Favio (2023): Reinstatement of the genus Psorodendron and related systematic novelties as revealed from phylogenetic analyses of the tribe Amorpheae (Leguminosae, Papilionoideae).

03E7065CFFEED538FCDEF892FB68FB3E.taxon	discussion	4. Dalea is paraphyletic with respect to Marina, as D. filiciformis results sister to Marina. This result was obtained in all the partitioned and the combined analyses, including that based on the ITS- trnK / matK dataset with a significantly increased sampling within the species-rich Dalea. The bootstrap values that support this particular result ranged from 95 % in the ITS-based analysis (Suppl. Fig. 1) to 100 % in the combined ITS + matK / trnK analysis (Fig. 2). Barneby (1977: 149) already stated that D. filiciformis “ has no really close relative in Dalea and its affinities are difficult to estimate, ” and pointed out its pod morphology resembles that found in Marina species. Thus, the following formal transfer is required:	en	Urrego, Paola Piñeros, Suárez-Barón, Harold, Pabón-Mora, Natalia, González, Favio (2023): Reinstatement of the genus Psorodendron and related systematic novelties as revealed from phylogenetic analyses of the tribe Amorpheae (Leguminosae, Papilionoideae). Caldasia 45 (1): 49-65, DOI: 10.15446/caldasia.v45n1.96498, URL: https://doi.org/10.15446/caldasia.v45n1.96498
03E7065CFFEFD53DFCDEFB2BFA82FB2A.taxon	discussion	The transfer of Dalea filiciformis to the genus Marina (suggested but not formally validated by McMahon and Hufford, 2004) is consistent with the presence of pedicellate flowers and harp-shaped pods with two distinct crescents of blister glands, two traits that are distinctive of Marina (Barneby 1977). However, other morphological traits commonly found in Dalea and likely present in M. filiciformis, such as leaflets with minute blister glands, two collateral ovules per ovary, spiral trichomes on the calyx, and a preliminary chromosome counting of 8 (versus leaflets with lineariform glands, one ovule per ovary, calyx trichomes not spirally twisted, and x = 10 in most Marina spp.) remain to be studied in detail. Finally, the phylogenetic relationships of the Colombian species of Dalea (D. coerulea, D. cuatrecasasii, D. foliolosa and D. wilsonii) remains uncertain. The analysis based on ITS does not recover them as monophyletic (Suppl. Fig. 1), as D. coerulea results closely related to the Peruvian D. myriadenia and D. weberbaueri, whereas D. cuatrecasasii clusters with D. bicolor and D. versicolor, from southern United States and Mexico. Conversely, in the analyses based on matK / trnK (Suppl. Fig. 3) and the combined ITS + matK / trnK (Fig. 2), they come out as monophyletic, clustered either with D. pulchra, from southern United States, or with D. melantha, from southern North America and Mexico, respectively. More data are required to arrive at a better understanding of the phylogenetic relationship between the North- and Mesoamerican species of Dalea and their South American congeners.	en	Urrego, Paola Piñeros, Suárez-Barón, Harold, Pabón-Mora, Natalia, González, Favio (2023): Reinstatement of the genus Psorodendron and related systematic novelties as revealed from phylogenetic analyses of the tribe Amorpheae (Leguminosae, Papilionoideae).
