7D6687F2FFD5FFA3BCA70F3B63774EAC.taxon	etymology	Etymology: — The name of this species is in memoriam of the Colombian botanist Diego Yepes, who sadly died at a young age in 2018. He was a passionate orchidologist, mainly studying orchids from the Sierra Nevada de Santa Marta, and he accompanied the first author on an expedition to find new specimens of this species in 2015.	en	Jara-Muñoz, Orlando Adolfo, Richardson, James E., Zabala-Rivera, Juan Carlos (2021): Five new species and three new varieties of Begonia section Casparya endemic to Colombia.

7D6687F2FFD5FFA3BCA70F3B63774EAC.taxon	distribution	Distribution and habitat: — Endemic to the Northern and Western part of the Sierra Nevada de Santa Marta, between 1400 and 2000 m. This elevation range is included in a zone of cloud forest vegetation, and characterized as sub-Andean forest (Cuatrecasas 1958, Hernandez-C. & Sanchez 1992). The well conserved patches of forest in this zone have a canopy between 25 and 35 m tall, the undergrowth has abundant arborescent ferns and palms, as well as many epiphytes and woody lianas. The species was seen growing on rocks of a small stream, covered by dense arborescent vegetation, and surrounded by shrubs, herbs and mosses. Conservation status: ― We assess this species as endangered (EN B 2 a, b (ii )) because its EOO is less than 5000 km 2 (21.2 km 2), and AOO is less than 500 km 2 (12 km 2), and it is known from fewer than five locations (criterion B 2 a) and an observed reduction in the area of occupancy (criterion B 2 b (ii )). Close to the area where the species grows is the Sierra Nevada de Santa Marta National Park, a conservation area, however the lower park border is at 2000 m elevation, while the species grows just below this level, so the known populations are not protected. The area covered by montane forest in the region has declined drastically during the last five decades, in some cases the reduction of the original vegetation is 80 % (Fundación ProSierra 1991). Notes: — This species is part of the group II, sensu Jara et al. (2019) of Casparya, which is characterized by unisexual inflorescences, with solitary pistillate flowers, and acolumnar fruits. ITS sequences of this species were included in Jara et al (2019), (sp. nov. 7), showing evidence for its close relationship with species in the eastern Cordillera with similar morphological characteristics to B. pax and B. solaniflora. This species can be distinguished from the rest of the group by its curved anther connectives, the stamens connivent forming a cylindrical structure, and its larger staminate flowers.

7D6687F2FFD3FFA1BCA70F8362D34E14.taxon	etymology	Etymology: — This species honors the Colombian botanist Gloria Amparo Galeano (1958 - 2016), who was an outstanding specialist in the systematics and ethnobotany of palms. She also made important contributions to knowledge of the Colombian flora, mainly in the Choco region, and was director of the Instituto de Ciencias Naturales (ICN) from 2003 to 2006. In her thirty years on the staff of the ICN, Dr. Galeano collected hundreds of specimens, including one of the first collections of this new species of Begonia.	en	Jara-Muñoz, Orlando Adolfo, Richardson, James E., Zabala-Rivera, Juan Carlos (2021): Five new species and three new varieties of Begonia section Casparya endemic to Colombia.

7D6687F2FFD3FFA1BCA70F8362D34E14.taxon	distribution	Distribution and habitat: — This species is restricted to the eastern basin of the eastern Colombian Cordillera, and has been collected in two distant localities in the Departments of Boyacá and Cundinamarca. Populations have been found in cloud forest, from 1700 to 2500 m, in well conserved and shadow zones, and close to waterfalls or streams. There are no herbarium specimens of the population from Cundinamarca, however living material is available at the Bogota Botanic Garden, accession number 1941130028. Conservation status: ― We included this species in the category of vulnerable (VU B 2 a, b (iii )), according to criterion B, because it has an EOO estimated to be less than 20000 km 2 (88.4 km 2), the AOO is less than 2000 km 2 (16 km 2), and it is known from no more than 10 locations (criteria B 2 a), and grows in a region of continuing habitat reduction (criteria B 2 b (iii )), as evidenced by several studies in the Colombian eastern cordillera (e. g. Etter and Villa, 2000; Armenteras et al. 2003). Notes: — This new species was frequently misidentified in herbaria as B. cornuta, to which it is closely related, as showed by the ITS evidence in Jara et al. (2019). In this phylogeny B. galeanoi was temporarily designated “ Begonia sp. nov. 4. ”. Both species can be easily distinguished using the diagnosis presented here.

7D6687F2FFD1FFACBCA70FDB637348B4.taxon	distribution	Distribution and habitat: — This variety occurs in the Las Orquideas National Park and surrounding areas, in the north-west of the Colombian Western Cordillera, between 960 and 2300 m. It grows in the understory of well conserved forest, usually on the banks of streams. Notes: — This is the second variety apart from the type variety of B. kalbreyeri, a Colombian endemic species, common in the well conserved forest of the north of the central and western basin of the central cordillera. The type variety is only known from the type collection in the Paramillo region (ca. 2100 to 2400 m), in Antioquia, at the extreme north of the Colombian Cordillera Occidental, close to the current “ Paramillo ” National Park. Populations from about 50 km to the south of the type locality are morphologically distinctive, growing in the Orquideas National Park, these show variation in hair density being in general less pubescent than the type specimen and are described here as a new variety. According to Smith & Schubert (1955), Begonia kalbreyeri var. glabra differs from the type variety in being completely glabrous, however the type specimen is clearly not glabrous, having hairs mainly on veins of the leaves, stems and inflorescence.

7D6687F2FFDCFFACBCA7087B66C74FF4.taxon	distribution	Distribution and habitat: — Begonia mamapachensis is endemic to the mountains known as Cerro Mamapacha, shared by the municipalities of Garagoa, Chinavita and Miraflores in the department of Boyacá on the eastern Colombian Cordillera, in a range between 2100 and 2500 m. Plants of this species have been found growing in the understory of the cloud forest, usually along tracks and stream borders. Conservation status: ― We included this species in the category of Endangered (EN B 2 a, b (iii )), because its EOO is less than 5000 km 2 and AOO is 8.4 km 2, it is not known to exist in more than five locations (B 2 a), and there is evidence of a reduction in the area and quality of habitat (B 2 b (iii )) (e. g., Etter and Villa, 2000; Armenteras et al. 2003). Notes: — This species was named “ Begonia sp. nov. 5 ” in the phylogenies presented by Jara et al. (2019) and belongs to the clade V, which includes species with red flowers from the western Colombian cordillera and the broadly distributed and polymorphic Begonia urticae.

7D6687F2FFDAFFA9BCA70C1967824CA4.taxon	diagnosis	Diagnosis: — This species can be distinguished from Begonia trianae due to the smaller size of the plants (to 40 cm tall vs.> 40 cm tall in B. ursina) and its succulent stems (vs. fibrous). The staminate flowers in B. perijaense have shorter pedicels than B. trianae (to 9 mm vs. 40 - 60 mm long) and the perianth has 6 tepals (vs. 5). It can be distinguished from Begonia ursina by the smaller plant size (to 40 cm tall vs.> 40 cm tall), succulent stems (vs. fibrous), its leaf laminae oblique to the petiole (vs. straight), and its longer leaf laminae (4.9 − 9.5 vs. 11 – 14.5 cm). From Begonia chlorolepis it can be distinguished by the fruit having the apex of the horns vertically flattened (i. e., compressed) vs. horizontally flattened (i. e. depressed).	en	Jara-Muñoz, Orlando Adolfo, Richardson, James E., Zabala-Rivera, Juan Carlos (2021): Five new species and three new varieties of Begonia section Casparya endemic to Colombia.

7D6687F2FFDAFFA9BCA70C1967824CA4.taxon	distribution	Distribution and habitat: — Only known from the type specimen in the peak Cerro Pintado (also spelled “ Cerro del Pintao ” and known as “ Cerro Viruela ” in Venezuela), which is one of the highest mountains of the Perijá serrania, reaching 3300 m (Rangel 2009). Vegetation there is sub-paramo dominated by Calamagrostis sp., and accompanied by several species of Asteraceae, as well as Hesperomeles ferruginea, Otholobium sp. (Fabaceae), Geranium sp. (Geraniaceae) and Monnina sp. (Polygalaceae) (pers. obs.). The peak is formed of upper Cretaceous limestone from the Cogollo formation, and has geomorphological evidence of glaciations (Lazala 2007, Rodriguez & Galán 2008). Conservation status: ― We included this species in the category of Critically Endangered (CR B 2 a, b (iii )) according to the IUCN criteria B 2, because its AOO is less than 10 km 2, being only about 1 km 2, based on the only known population, and the EOO is less than 100 km 2. It is found at only one location, and there is evidence of destruction of the vegetation during the last 30 years, even though this zone is included in a forest reserve (Vásquez & Serrano 2009). Notes: — Begonia perijaensis grows very close to Begonia ursina, which is the most common species of the section in the Serranía de Perijá, ranging between 2300 and 3100 m, while B. perijaensis is restricted to the higher part of the Cerro Pintado peak.	en	Jara-Muñoz, Orlando Adolfo, Richardson, James E., Zabala-Rivera, Juan Carlos (2021): Five new species and three new varieties of Begonia section Casparya endemic to Colombia.

Notes: — As well as the shorter petioles, this variety has 4 instead of 5 tepals in the pistillate flowers. It is likely that this reduction is derived from the fusion of two inner tepals, as the bilobulate form of the largest tepal suggests. This variety is also sympatric with Begonia libera and shares numerous vegetative and reproductive features, however Begonia libera can be recognized by its hispidous stems, and papillate-pubescent leaves.
