Fruit unknown.</p><p>Distribution and ecology. – Eremolaena darainensis is restricted to the Bekaraoka and Ampondrabe forests in the Loky-Manambato (Daraina) region in north-eastern Madagascar (Fig. 3). Among the more than 54,000 individual plants documented during recent floristic inventory work and vegetation studies conducted in this area, only 39 were found of E. darainensis USBAUMER &amp; al., 2011), including just two fertile trees. Eremolaena darainensis is the northernmost member of the genus, separated by nearly 250 km from the closest known locality of E. rotundifolia (F. Gérard) Danguy just north of Cap Est, and almost 350 km from the most northern population of E. humblotiana Baill. Eremolaena darainensis is only known from flowering material gathered in January and February; no fruiting collections have yet been made. It grows in semi-deciduous (transitional) forest with a dense canopy reaching to 7- 12 m and a dense under-storey of shrubs. Our new species occurs at 250-550 m elevation and is usually found on fairly steep (20- 40°) slopes in fine soil on rocky outcrops. The most abundant co-occurring species include, in decreasing order, Euphorbia geroldii Rauh (Euphorbiaceae), Asteropeia amblyocarpa Tul. (Asteropeiaceae), Cleistanthus suarezensis Leandri (Phyllanthaceae), and Rinorea angustifolia (Thouars) Baill. (Violaceae) .</p><p>Conservation status. – Eremolaena darainensis is currently known form five subpopulations, all of which are encompassed within the Loky-Manambato forest, which has been accorded temporary protection by the Malagasy government as a “Station Forestière à usages Multiples” (SFUM, Multiple Use Forestry Station), which falls short of full protection, indicating that some continuing decline of the quality of the habitat can be projected. Therefore, with an Extent of Occurrence (EOO) of 81 km 2, an Area of Occupancy (AOO) of 54 km 2, and five locations (calculated following CALLMANDER &amp; al., 2007), as well as estimated number of mature individuals (based on extrapolation of the inventory data) of less than 2,500, with none of the five subpopulations estimated to contain more than 250 mature individuals, E. darainensis can be assigned a risk of extinction of “Endangered” [EN B1ab(iii)+ 2ab(iii); C2a(i)] following the IUCN Red List Categories and Criteria (IUCN, 2012).</p><p>Notes. – Using the key to species of Eremolaena provided by LOWRY &amp; al. (2000), material of this new species would be identified as E. rotundifolia . It can, however, be distinguished from the two other members of the genus by several foliar and floral features, as well as differences in substrate preferences and geographic distribution (Fig. 3). In order to facilitate identification of material of Eremolaena, the following updated key is provided.</p><p>Key to the species of Eremolaena Baill.</p><p>1.

Inflorescence comprising 1 or 2 (rarely 3) unbranched axes, each with a pair of bracts borne near the middle and bearing 1 or 2 terminal flowers, axis ca. 10 mm in bud, expanding to 20-22 mm at anthesis, moderately to densely papillose stellate-strigose, bracts broadly elliptic to nearly circular, 4 × 3-4 mm, apex rounded, minutely stellate on abaxial surface, pubescent on adaxial surface, caducous, ultimate axes below the involucre 6-10 mm long, moderately papillose stellate, involucre in flower broadly cupuliform, with numerous cylindrical to narrowly triangular teeth, moderately to densely papillose stellate on both surfaces, containing 1 or 2 sessile flowers; sepals 3, imbricate, broadly ovate, adaxially concave, 9-10 × 6 mm at anthesis, with short stellate-papillose indumentum on the exposed part of the abaxial surface, the portion hidden by the overlapping adjacent sepal with both papillose stellate and short lanate indumentum, margins entire, the hidden portion tinged deep pinkishred, apex rounded to acute; petals 5, obovate, bright pinkish red, yellow toward the margins, slightly succulent in fresh material, chartaceous when dry, 10-14 × 6-8 mm, with dense, appressed sericeous indument in the central portion of the abaxial surface, glabrous toward the entire margins, glabrous on the adaxial surface, apex rounded to broadly acute; stamens ca. 90-100, filaments slender, ca. 4 mm long, glabrous, anthers elliptic to nearly circular, 0.8 mm long, introrse, dehiscent through longitudinal slits; ovary broadly conical, densely white woolly tomentose, 3-locular; style cylindrical, erect, ca. 9 mm long, stigma terminal, minutely 3-lobed, glabrous.

However, until permanent protection has been established, the forest is still potentially subject to local disturbance and illicit exploitation, especially along its eastern edge where S. charlotteae has been collected. Therefore, with a very restricted AOO of ca. 20 km 2 and only a single location, coupled with the possibility for rapid decline due to the effects of human activities if protection of the Bemangidy-Ivohibe forest is not maintained, S. charlotteae can be assigned a risk of extinction of “Vulnerable” [VU D2] following IUCN Red List Categories and Criteria (IUCN, 2012).</p><p>Notes. – Schizolaena charlotteae is part of a morphologically coherent group of species that also includes S. laurina Baill., S. milleri Lowry &amp; al. and S. rosea Thouars, characterized by several features including: glabrous petioles and young branches; dense, straight, appressed indumentum on the abaxial surface of the petals; ovate and usually persistent stipules and inflorescence bracts; and an involucre in fruit that is broadly to narrowly cupuliform or funnelform. Indeed, one of the collections of our new species, Service Forestier 28662, was originally assigned by LOWRY &amp; al. (1999) to S. milleri, known otherwise only from littoral forest on white sand and low elevation humid forest on laterite, from near the village of Ambavala (north of Sambava) extending south to Foulpointe, fully 800 km to the north of the only known locality of S. charlotteae .</p><p>Using the key to species of Schizolaena provided by LOWRY &amp; al. (1999), material of this new species would be identified as S. milleri . However, it differs in several features of the flower and fruiting involucre, as indicated below in Table 1. Specimens of Service Forestier 28662 at P were originally annotated as ‘ S. delphinensis ’ by J.-F. Leroy, but the name was never validly published.</p><p>The Bemangidy-Ivohibe forest has been the focus of intensive botanical inventory conducted over the last decade by teams from the Missouri Botanical Garden and the Rio Tinto-QMM mining company in order to assess its suitability as a conservation offset site (BIRDLIFE INTERNATIONAL, 2011; TEMPLE &amp; al. 2012). Dozens of new taxa have been documented from Bemangidy-Ivohibe, some of which have already been described, including new genera of Sapotaceae, Bemangidia L. Gaut. AUTIER &amp; al., 2013) and Asteraceae, Lowryanthus Pruski RUSKI, 2014) and new species in several families such as Gnidia razakamalalana Z. S. Rogers ( Thymelaeaceae; ROGERS, 2006), Ivodea anosiensis Rabarim. &amp; al. and I. macrocarpa Rabarim. &amp; al. ( Rutaceae; RABARIMANARIVO &amp; al., in press), and Micronychia bemangidiensis Randrian. &amp; Lowry ( Anacardiaceae; RANDRIANASOLO &amp; LOWRY, 2009).</p><p>Etymology. – This species is named in honor of our friend and colleague Professor Charlotte Rajeriarson, recently retired from the Université d’Antananarivo, who has played a key role in training an entire generation of Malagasy botanists, and who served as the first President of the IUCN Madagascar Plant Specialist Group, helping to ensure the successful establishment of this important national initiative.</p><p>Paratypes. – MADAGASCAR.

Fruit unknown.</p><p>S. parvipetala S. gereaui</p><p>Distribution and Ecology. – Schizolaena parvipetala, like S. charlotteae described above, appears to be restricted to lowland humid forest of southeastern Madagascar, where it has been recorded to the W of Mahatalaky and at Bemangidy-Ivohibe in the Tsitongambarika New Protected Area, respectively ca. 20 and 55 km N of Tolagnaro (Fig. 3).</p><p>Conservation status. – Schizolaena parvipetala is known from only two localities, one of which (Bemangidy-Ivohibe) currently has temporary protection (but see the assessment of Schizolaena charlotteae above) while the other (W of Mahatalaky) lacks any protection. Therefore, with an AOO of ca. 20 km 2 and projected continuing decline as a result of forest conversion and degradation at the second location, S. parvipetala can be assigned a risk of extinction of “Endangered” [EN B2ab(ii,iii,iv,v)] following IUCN Red List Categories and Criteria (IUCN, 2012).</p><p>Notes. As its name suggests, Schizolaena parvipetala stands out by having the smallest flowers of any member of the genus. It closely resembles S. gereaui, which also occurs in south-eastern Madagascar, and specimens would be identified as that species using the key provided by LOWRY &amp; al. (1999). However, S. parvipetala differs by several foliar and floral characters, as summarized in Table 2.</p><p>Paratypes. – MADAGASCAR. Prov.
