Angraecum section Humblotiangraecum Schltr., Fedde, Repert. Sp. Nov., Beih. 33: 310 (1925).
Description:
Epiphytic on canopy or trunk, medium to large plants (to 35 cm height); stems erect, short or barely developed, internodes short to elongated (to 5 cm); leaves thin to thick, coriaceous or fleshy; inflorescences racemose, with up to four flowers, suprafoliar, longer than leaves, one to four per stem; flowers very large, white, sepals and petals linear-lanceolate to lanceolate-ovate; labellum lowermost, broadly ovate, deeply concave, longer or equaling dorsal sepal, sometimes white overlaid green at the moth, apex acute; spur long (to 15 cm), with a wide often infundibuliform opening, tapering from the median to tip, greenish white towards the tip; ovary triquetrous or round in section with 180° resupination.
Notes:
The plants in this section are kept apart from those of the section Angraecum primarily by the stemless habit. A. potamophilum Schltr. with its lorate-falcate leaves surely belongs to this section.
