Mens. Soc. Linn. Paris 1: 413 (1884).</p><p>TYPE. — Eremolaena humblotiana Baill.</p><p>The genus Eremolaena comprises two species, both of which have been recognized for many decades. Vegetatively they closely resemble several species in the two putatively related genera, including Pentachlaena orientalis, Perrierodendron capuronii, and P. occidentalis, and can sometimes be difficult to recognize without flowers and/or fruits. Distinctive features of the genus include strongly unequal sepals (the outer two being much smaller), an ovary with 3 carpels (vs. 2 in Perrierodendron and 5 in Pentachlaena), and a dehiscent fruit (also present in Pentachlaena) containing only 2 seeds in each locule.</p><p>Key to the species of Eremolaena</p><p>1. Leaves subcoriaceous, largest blades at least 9 cm long, secondary and tertiary venation distinctly raised on abaxial surface; sepals 15-19 mm long at anthesis; flowers borne in pairs, subtended by 5 small, scale-like involucral lobes; humid and subhumid forest on laterite, Betampona RNI, Lac Alaotra region, and Brickaville to Vatomandry ................................................................................................................ 1.

Perrier.</p><p>The genus Pentachlaena was originally described with a single species ( P. latifolia), which is restricted to the Col des Tapias, the Ibity massif, and the area immediately to the south. CAPURON (1970) mentioned a second member of the genus growing at low elevations in the east, which he later described (CAPURON 1973) as P. orientalis . Here we describe a third species, known only from the type collection in flower, made at Betampona RNI over 40 years ago, but which could very well still occur in the wild, considering how many other rare species characteristic of low elevation humid evergreen forest have been rediscovered there within the last several years. Pentachlaena can be distinguished from its presumed relatives by its dehiscent, 5-locular fruit with a particularly thick, almost woody exocarp, in which each locule contains 4-6 seeds.</p><p>Key to the species of Pentachlaena</p><p>1.

Mus. Natl. Hist. Nat., sér. 2, 23: 138 (1951).</p><p>TYPE. — Perrierodendron boinense (H. Perrier) Cavaco.</p><p>C AVACO (1951) described Perrierodendron based on a species originally assigned to Eremolaena by PERRIER DE LA BÂTHIE (1925), but which was clearly distinct from that genus on the basis of several features, especially the presence of an indehiscent, 2-locular fruit subtended by an accrescent, entire involucre. CAPURON (1970) mentioned two additional species, but declined to describe them for lack of sufficient material. J.-F. LEROY began preparing a manuscript describing these and two additional new species shortly after CAPURON’ s death in 1971, but it remained unpublished at the time he passed away in early 1999. A careful re-evaluation of his work and comparison of the material of Perrierodendron now available shows that five well delimited species can indeed be recognized, four of which are newly described here. Two of these taxa are represented by several collections in flower and fruit, and although the other two are known from very limited material, they appear to be amply distinct to justify describing them at this time.</p><p>Key to the species of Perrierodendron</p><p>1. Leaves and petioles pubescent even when mature, indumentum totally covering the abaxial surface; lateral branches with leaf scars almost as wide as the stem, internodes 1.5-3(-4) mm long, giving the stem an evident “zig-zag” appearance; involucre in fruit forming a minute cupule, apex of fruit tapering into a prominent rostrum ca. 1/2 the length of the fruit body; Tapia woodland on quartzite, Itremo. 4.

We associate the holotype with the other collections based primarily on similarities in their inflorescence structure and leaf color, texture and venation, as well as the fact that the blade is distinctly shiny on its adaxial surface. The sites at which the paratype collections were made near Moramanga are over 400 km to the SSW of the type locality (Fig. 4), and may be situated closer to sea level. However, until additional material at other stages of development becomes available from either or both areas, it seems best to treat them as belonging to a single species.</p><p>Perrierodendron capuronii can be distinguished from other members of the genus by its leaves with a shiny adaxial surface, its obovoid and weakly bi-lobed, 2-seeded fruit covered with very short stellate indumentum, and its reflexed involucre with an undulate margin.</p><p>ETYMOLOGY. — The specific epithet honors the renowned forest botanist René CAPURON, who contributed so much to our understanding of the Malagasy flora, and who took a special interest in the taxonomy and morphology of the island’s endemic plant families.</p><p>VERNACULAR NAMES. — Ampaliala, Tanantanampotsy.</p><p>PARATYPES. — MADAGASCAR, Prov.

It occurs on sandy substrates in seasonally dry, deciduous forests. With the exception of one collection made in 1973 and another last year, P. occidentalis has not been recorded since the early 1960s. This species closely resembles P. boinense, but can be distinguished from it by having smooth (unribbed) fruit with the apex extended into a short, conic rostrum, a thin, crustaceous endocarp, and sepals ca. 5-6 mm long and petals ca. 8-9(-10) mm long.</p><p>VERNACULAR NAMES. — Fotona, Nato, Tsiandala, Tsitaka.</p><p>PARATYPES. — MADAGASCAR, Prov.
