Ecology and distribution
Trop. Afr.
Biology : Epiphytic, sometimes lithophytic, robust herb; pseudobulbs 2-10 cm apart, 2(-3)-leaved, ovoid, 3,5-10x1-3 cm, flattened, 3-5-angled, angles knobby; leaves petiolate (1-12 mm), oblong to linear-lanceolate, 3,8-20x1,3-5,5 cm, thick; inflorescence erect, 15-90 cm long, 16-20-flowered; peduncle erect, swollen towards tip, 6-42 cm long; rachis flattened, blade-like, 6-56 cm long, 0,5-5 cm wide, yellowish or greenish, often spotted with purple, edges sharp, straight to undulate; bracts spreading-reflexed, elliptic, 2,5-7x2-4 mm; flowers distichous, borne on a median or excentric line, yellow or greenish, spotted with purple; sepals recurved, lanceolate, acuminate, 4-8x1-3,5 mm; petals not recurved, lanceolate, 2-3x0,3-0,8 mm; lip recurved, oblong, 1,5-3x0,7-1,4 mm, glabrous, fleshy.
Ecology : Primary and secondary forest; gallery forest; open woodland; Brachystegia or Aucoumea-Brachystegia woodland; mixed deciduous woodland; on, e.g., Eucalyptus in mixed forest, Carapa grandiflora, Persea americana, etc.; 0-1900 m alt.
  A natural hybrid B. maximum x B. scaberulum var. scaberulum is reported from E Zimbabwe by Vermeulen (1987): 100-101, and by Fibeck & Mavi (in Kirkia 17: 147-149, 2001).
  Bioko/Fernando Poo, S. Tomé, Príncipe (Acta Bot. Gall. 147: 170, 2000; Bothalia 41: 63, 2011), Annobón (Fragm. Florist. Geobot. 43/1: 21, 1998; Phytotaxa 171: 23, 2014). – Ethiopia ? (not in Fl. Eth. & Eritrea 6, 1997).
  Shape and colour of rachis very variable; “although at first sight the forms look very different, the flowers are identifical” (la Croix & al., Orchids Malawi: 203, 1991). “Too many intermediate plants [B. maximum-B. oxypterum-B. platyrhachis incl.] are found which blur the distinctions based on rachis shape and marginal undulation” (Cribb in Fl. Trop. E. Afr., l.c.). – However, Fibeck & Phiri (in S. Afric. Orchid J. 28/2: 38-41, 1997) consider B. platyrhachis as distinct from B. maximum.
