Angraecum vesiculatum

Names and Taxonomy

Angraecum vesiculatum Schltr. is the accepted name for this species according to Kew’s Plants of the World Online.¹ The name was first published in Repertorium Specierum Novarum Regni Vegetabilis, Beihefte 33: 348 (1925). A later homotypic synonym is Gomphocentrum vesiculatum (Schltr.) Szlach., Mytnik & Grochocka, published in 2013.¹ No common names were found in the available sources.

How to Identify This Species

The only documented growth form is that of an epiphytic subshrub, typical of many Angraecum species. Detailed descriptions of leaf shape, size, stem length, flower colour, lip morphology, spur length, or fragrance are not present in the current sources, so identification must rely on comparison with herbarium specimens or expert‑verified photographs.

Because morphological details are lacking, collectors should verify the identity of any plant labelled Angraecum vesiculatum against a reliable taxonomic key or by consulting a specialist.

Native Range and Habitat

This orchid is endemic to the northern part of Madagascar.¹ It occurs in the wet tropical biome, growing as an epiphyte on tree branches in humid forest. Specific elevation limits, host tree preferences, or micro‑habitat details were not documented in the sources consulted.

Species‑Specific Care

Because specific cultural requirements for Angraecum vesiculatum have not been published, growers are advised to apply the general care guidelines used for other wet‑forest Angraecum species: bright, filtered light; high humidity; regular watering to keep the medium moist but not water‑logged; and good air circulation. Monitoring the plant’s response and adjusting conditions accordingly is essential.

Flowering and Pollination

No published information on the flowering period, flower morphology, fragrance, or pollinators for this species was found in the available sources.

Evidence and Limitations

The profile relies primarily on the taxonomic entry from Kew’s Plants of the World Online, which confirms the accepted name, synonym, and northern Madagascar distribution. Morphological, ecological, phenological, and horticultural details are absent from the cited material; consequently, many sections contain “Not documented.” Further field studies or specialist monographs would be needed to fill these gaps.
