A taxonomic revision of the genus Noronhia Stadtm. ex Thouars (Oleaceae) in Madagascar and the Comoro Islands Hong-Wa, Cynthia Boissiera 2016 2016-10-21 70 1 292 8WYRM Hong-Wa [503,741,380,408] Magnoliopsida Oleaceae Noronhia Plantae Lamiales 203 203 Tracheophyta species patricei    Typus: MADAGASCAR. Prov. Toamasina: Analanjirofo, Ambanizana, along path between Ambanizana-Andranobe, 15°38’29”S 49°57’54”E,  7 m,  25.X.2004, Antilahimena 2959(holo-: MO-6615553!; iso-: G[ G00341616]!, K!, P[ P03532773]!, TAN!).   Diagnosis   Noronhia patriceiHong-Wa can be distinguished from its congeners by its three-verticillate, large leaves, its fasciculate infructescences, and its large fruits characterized by a thick pericarp.   Description  Treesto 11 mtall, trunk to 16 cmdiameter; young twigs subquadrangular to cylindrical, 5.5-8.6 mmdiameter, glabrous; bark medium gray, rugose. Leavesverticillate, persistent; bud scales persistent; blades medium green above, lighter below, lanceolate, 26-36 3 4.5-9.5 cm, very coriaceous, glabrous, domatia absent, base acute, margin flat, apex acuminate, the acumen 5-12 mmlong, midrib deeply sunken above, distinctly raised below, secondary veins conspicuous, 14-20 per side, 19-40 mmapart, looping 2-7 mmfrom the margin; petiole medium to dark gray, 16-20 3 4-6.5 mm, entirely woody, glabrous. Flowersunseen, but infructescence thyrsoid, fasciculate. Fruitingpedicel 5-11 3 3.5-5 mm; young fruits green, yellow when mature, ovoid to oblong, 25-38 3 19.5-24 mm, surface smooth, sometimes covered with white dots, apex flat to bluntly pointed; dry pericarp 2.2-3 mmthick; endocarp woody; seed 15 3 20 mm.   Etymology  Thisspecies is dedicated to Patrice Antilahimena, a botanist at the Missouri Botanical Gardenin Madagascar, for collecting the typespecimen and for keeping an eye out for  Noronhiaduring his extensive fieldwork.   Distribution, ecology and phenology   Noronhia patriceioccurs in low-elevation humid forests and basement rocks and unconsolidated sands in the Masoala region in northeastern Madagascar( Fig. 36). It fruits from October to June.   Conservation status   Noronhia patriceiis currently known only from five collections representing five localities. The assessment resulted in an EOO of 1,023 km 2, an AOO of 20 km 2, and four subpopulations representing four locations, of which two occur within a protected area (Masoala). With decline in habitat quality, habitat loss and reduction of the number of mature individuals likely to continue outside of the protected area as a result of wood harvesting and land conversion, the small EOO and AOO as well as the small number of locations,  N. patriceiis assigned a preliminary status of “Endangered” [EN B1ab(i,ii,i ii,iv,v)+2ab(i,ii,iii,iv,v)].   Notes   Noronhia patriceiis similar to  N. crassiramosabut can be distinguished by its entirely verticillate (vs. verticillate only at the tips of the branches), lanceolate (vs. oblong) leaves, and its ovoid to oblong (vs. subglobose) fruits with a flat (vs. apiculate) apex. Its three-verticillate, large leaves, fasciculate infructescences, and large fruits characterized by a thick pericarp allow for the unambiguous identification of this species.    Paratypi   MADAGASCAR. Prov.
