Nat. 26: 669 (1920).  — Type:  Perrier de la Bâthie 13096, Madagascar, Prov. Antananarivo, rocailles, quartzite, Mt. Ibity,  1500 m, [ 20°07’S, 47°01’E],  Apr. 1920( holo-, P!;  iso-, K!, MO!, P!).    Pentachlaena latifoliais restricted to quartzite substrates in the Ibity and Analabe massifs ( Fig. 3), forming shrubs to small trees ( 5-6 mtall) that can be distinguished by their broadly elliptic to orbicular leaves, and flowers that are subsessile or borne on short peduncles less than 8 mmlong, and subtended by short, entire to slightly dentate bracts. This species appears to be able to tolerate fires by forming new shoots from the base after burning.  Pentachlaena latifoliahas been collected recently at Ibity, but has never been recorded in any of Madagascar’s protected areas.  MATERIAL EXAMINED. —    Bernardi 11591, Col des Tapias;   Dorr 4524, Ibity;   Lowry& Schatz 4818, Ibity;   Morat 3194, Ibity;   Perrier de la Bâthie 1998, Ibity,  2112, Bois des Tapias,  13096, 17903, 18499, Ibity;   Rakotozafy 435, Ibity;   Service Forestier 22668, Ambohimanjaka-Fierenantsoa,  23490,  Analabe-Ampandrianambilapa,  27393, Analabe;   Viguier 1496, Ambohiponana. 5183914301 1920-04 P Perrier de la Bathie Madagascar 1500.0 -20.116667 Mt.
