Biologie : Description of Listrostachys vandaeformis Kraenzl. in Orchis 2/12: 136-137, 1908 (without illustration): A very large, leafy plant; leaves lorate, linear, to 36x4 cm, apex unequally 2-lobed; inflorescences pendent, 25-30 cm long, many-flowered; rachis fleshy, articulate, bracts opposite; flowers yellow or white; sepals ovate-lanceolate, 15x3 mm, acuminate, reflexed at apex; petals similar, 12x2 mm; lip cordate at base, 10 mm long, 2 mm wide, margins fimbriate, with a tooth at base in mouth of spur; spur 5-6 mm long, laterally flattened, base inflated. Said to be related to D. pellucida. Description of Angraecum ledermannianum in Bot. Jahr. Syst. 51: 397, 1914 (type Ledermann 5662): Herb with stem; leaves numerous, linear, falcate, to 40x3 cm, apex unequally 2-lobed, inflorescences to 25 cm long; flowers in whorls of 2-3; sepals ovate-lanceolate, acuminate,12x2 mm; petals lanceolate, acuminate, 9x2 mm, margins dentate; lip broadly oblong or quadrate, 10x5 mm, margins fimbriate; spur c. 10 mm long, napiform, compressed, obtuse.
Ecologie : Ecology not recorded, probably epiphyte; 800 m alt. in N-Cameroon.
  In Fl. Cameroun 36: 748, 2001, Ledermann 5662 is treated under D. fragrantissima. Droissart & al., l.c., suggest that D. vandiformis be a probable synonym of D. fragrantissima. This is also the opinion of Stewart & al., Angraecoid orchids: 297, 2006. On comparing the descriptions of the species mentioned above we have tentatively put D. vandiformis in synonymy of D. fragrantissima (see above under this species).
