Ecology : |
Riverine forest and forest edges; amongst bracken at margin of stream bank forest; wet meadows at edge of gallery forest; wooded meadows; swampy and spongy areas, wet places, bogs, marshes; by streams, rivers, lakes; dambos; base of mountain slopes; secondary forest; fallow; usually but not always in heavy shade; 0-2600 m alt. |

“Very variable in both stature and flower size but this variation seems to be more or less continuous and does not warrant taxonomic recognition…” (Fl. Trop. E. Afr., Orchid. 3: 430, 1989). |

Bioko/Fernando Poo; Botswana, S. Africa (E coast). |
  |
May be distinguished from other Eulophia species by its flowers with tall crenulate lamellae on lip. |
  |
Cultivated for its spectacular flowers. L. horsfalli “originally flowered in the collection of J. B. Horsfall, Esq. in 1864”. It can be grown “on the edge of a pond, but also will thrive in rich soil, if watered well; the compost must be well drained” (Piers, 1968: 180). For cultivation, see, e.g.: Bellone in Orchidées, Cult. & Protection 24 bis: 18, 1996; Fibeck in Orchidee Hamburg 52/3: insert, 2001; Abel in Orchids S. Afr. 42/1: 62-65, 2011; all with photographs.
Seeds have been used for symbiotic germination in Kenya (Ochora & al. in Syst. Geogr. Pl. 71: 585-596, 2002). |
