03B687A92506FFA1B5B4FCC5521F2C26.taxon	diagnosis	Diagnosis: — Similar to P. triphyllum because in both species the petals are ligulate with claws auriculate, stamens straight, longer than the sepals, almost similar in length and protruding from the flower. They differ in that P. auriculipetalum has white to pale pink flowers and pinnately to bipinnately compound leaves, although juvenile leaves are often simple. The flowers of P. triphyllum are pink to a striking bright pink and leaves vary from simple or three-parted to many-parted. However, compound leaves are never as finely divided as in the case of P. auriculipetalum.	en	Marais, Elizabeth M.

03B687A92506FFA1B5B4FCC5521F2C26.taxon	distribution	Distribution: — Occurs in the Kouebokkeveld and around the Witteberge (Fig. 2). This distribution overlaps with that of P. triphyllum, although the latter has a much larger distribution area from Nieuwoudtville in the north to Riviersonderend in the south and an extention to Aberdeen in the east (Fig. 2). Collections of P. triphyllum were usually made at higher elevations (Marais 1994) in areas with an annual precipitation higher than 400 mm. Both species occur in fynbos on sandstone derived soil or on clay or shale bands and both flower from October to December. Diagnostic characters: — Pelargonium auriculipetalum is a deciduous geophyte with small white to pale pink flowers, ligulate petals with claws auriculate, five fertile stamens, stamens remaining straight during anthesis, almost similar in length and always longer than the sepals and pinnately to bipinnately compound leaves. Conservation status: — Because of extensive agricultural activities in the Kouebokkeveld the areas with natural vegetation are declining and this species could be under threat. However, more in depth exploration is needed for the correct assessment of the extinction risk of this species. Therefore, according to IUCN (2024) guidelines, it is previously indicated as Data Deficient (DD).	en	Marais, Elizabeth M. (2024): Three new species of Pelargonium, section Hoarea (Geraniaceae) from the Western Cape Province, South Africa.

03B687A92506FFA1B5B4FCC5521F2C26.taxon	etymology	Etymology: — The specific epithet refers to the auriculate claws of the petals (Latin auriculatus, furnished with ear-like appendages). Notes: — The flowers of P. auriculipetalum and those of P. triphyllum are very similar. In both species the posterior petals are ligulate with auriculate claws, both have relatively short hypanthia (5 – 19 mm long) and long stamens protruding from the flower. The five fertile stamens are almost similar in length and are always longer than the sepals. The stamens remain straight during anthesis. In both species the scape is branched with 2 – 4 (– 5) pseudo-umbellets and (3 –) 6 – 8 (– 10) flowers per pseudo-umbellets, and they have the same indumentum on the leaves, scape, peduncle, hypanthia and sepals. The structure of the pollen grains of both species is very similar. The equatorial diameter of the pollen grains in both species lies between 53 – 74 μm (P. triphyllum: 60 – 68 μm; Marais 1994 and P. auriculipetalum: 53 – 74 μm) and the structure of the tectum in both species can be described as striate-reticulate (Marais 1994). However, they differ with regard to flower colour, leave shape and chromosome numbers. In P. auriculipetalum 2 n = 18 (Focke Albers, pers. comm.) and in P. triphyllum 2 n = 20 (Gibby et al. 1996; Touloumenidou et al. 2004). The ligulate petals and the long stamens of P. auriculipetalum and P. triphyllum resemble those of P. auritum (Linnaeus) Willdenow (1800: 644), although in the latter the staminal column is papillate whereas in the first-mentioned two species the column is smooth (Marais 1994).

03B687A92503FFA3B5B4FEBE53312A40.taxon	diagnosis	Diagnosis: — Similar to P. pinnatum and P. reflexum (Andrews) Persoon (1806: 227) because all of them have spathulate petals and very short stamens concealed in the floral sheath. All three of them have white flowers, although in P. pinnatum a variation of pink and yellow flowers also occurs. They differ in that P. leucopetalum has prominent dark red blotches on the anterior petals, a characteristic lacking in the other two species. Pelargonium leucopetalum has upright pinnately divided leaves, trullate in outline, pinnae irregular in outline and very thin petioles, P. pinnatum has also upright pinnately divided leaves but narrowly oblong in outline with pinnae regular in outline and P. reflexum has prostrate trifoliolate leaves.	en	Marais, Elizabeth M.

03B687A92503FFA3B5B4FEBE53312A40.taxon	distribution	Distribution: — Along the west coast of the Western Cape Province, from Paleisheuwel and Aurora in the west and more inland to Pakhuis Pass and Nardous Pass in the east (Fig. 4). Diagnostic characters: — Pelargonium leucopetalum has white flowers with feather-like markings on the posterior two petals and prominent dark red blotches on the anterior three petals, a characteristic rather unusual for flowers of sect. Hoarea, and pinnately divided leaves, trullate in outline, and very thin petioles. The spathulate petals and the very short fertile stamens are similar to those of P. pinnatum (Marais, 1994). About thirty other species of sect. Hoarea are also known for the very short stamens concealed in the floral sheath, of which P. reflexum and P. violiflorum (Sweet) Candolle (1824: 652) have white flowers with spathulate petals. The flowers of P. reflexum (posterior petals 10 – 18 mm long) are smaller than those of P. leucopetalum (posterior petals 17 – 27 mm long) and both species have wine-red feather-like markings on the posterior two petals. Pelargonium violiflorum has small flowers (posterior petals 7 – 12 mm long) without markings on the posterior petals. Both P. reflexum and P. violiflorum lack the prominent dark blotches on the anterior petals as in P. leucopetalum. Conservation status: — With an increase in agricultural activities along the west coast of the Western Cape Province this species may become under threat. However, more in depth exploration is needed for the correct assessment of the extinction risk of this species. Therefore, according to IUCN (2024) guidelines, it is previously indicated as Data Deficient (DD).	en	Marais, Elizabeth M.

03B687A92503FFA3B5B4FEBE53312A40.taxon	etymology	Etymology: — The specific epithet refers to the white petals of the species (Latin leuco, white). Notes: — The pinnately compound leaves, trullate in outline of P. leucopetalum resemble those of P. fumariifolium (yellow flowers), P. leptum L. Bolus (1932: 229, 232), P. undulatum (Andrews) Persoon (1806: 226) and P. violiflorum (white flowers). The indumentum on the laminae and petioles of these five species is very similar. In all of them the laminae are hirsute with long appressed stiff hairs (Marais, 1994). In P. fumariifolium the stiff hairs are interspersed with short glandular hairs and in P. undulatum and P. violiflorum the adaxial sides are usually glabrous. The petioles of all of them are hirsute with appressed hairs, usually shorter than those on the laminae and in P. undulatum, P. violiflorum and P. leucopetalum these hairs are interspersed with short glandular hairs. On the petioles of P. fumariifolium and P. leptum the glandular hairs are lacking.

03B687A92501FFADB5B4F88D532F2E72.taxon	diagnosis	Diagnosis: — Similar to P. luteum and P. fumariifolium because all three species have linear to narrowly spathulate petals with pale pink Vshaped markings on the posterior two and the filaments of the lateral stamens are twisted so that the pollen surfaces are facing to the front. They differ in that P. tortandrum has three or four, seldom five fertile stamens and simple, seldom trifoliolate, ovate, prostrate leaves, P. luteum has always five fertile stamens and erecto-patent, pinnately compound leaves with the lamina elliptical in outline, and P. fumariifolium has only two fertile stamens, which are in the lateral position, and five very long staminodes in the anterior position, both these characteristics are unique within Pelargonium (Marais 1981, 1994). The latter has also erecto-patent, pinnately compound leaves, but the lamina is trullate in outline.	en	Marais, Elizabeth M.

03B687A92501FFADB5B4F88D532F2E72.taxon	distribution	Distribution: — So far only known from a small area in the Robertson Karoo (Fig. 6). Diagnostic characters: — Pelargonium tortandrum is a small geophyte with pale yellow flowers and simple, seldom trifoliolate prostrate leaves. The flowers have linear to narrowly spathulate petals with pale pink V-shaped markings on the posterior two, and three or four, seldom five fertile stamens with the filaments of the lateral two stamens twisted so that the pollen surfaces are facing to the front (Fig. 5 a). Conservation status: — Pelargonium tortandrum occurs in a small area next to the Afrimat, Cape Lime, industrial development at Langvlei and can be under threat if this development should expand in future. Given the low values of Area of occupancy (AOO) and Extent of occurrence (EOO), together with the detected possible threat, this species will probably fall in an IUCN (2024) category with high risk of extinction. Nevertheless, further exploration is necessary to determine population size and dynamics. Therefore, the species is here provisionally indicated as Data Deficient (DD), even if in similar cases rare and threatened species are often assessed as Critically Endangered (CR) (Perrino et al. 2023; Yan & Hao 2024).	en	Marais, Elizabeth M.

Notes: — The distribution of P. tortandrum is very small if compared to the wide distribution of the related P. fumariifolium. The latter occurs from Kaus Mountains in Namaqualand in the north to Ceres-Karoo in the south and Whitehill in the east. This overlaps with the distribution of the second related species, P. luteum around Nieuwoudtville and Calvinia and boardering that of P. tortandrum in the Robertson Karoo (Fig. 6).
