Angraecum teres

Names and Taxonomy

Angraecum teres Summerh. is the accepted scientific name for this species according to Kew’s Plants of the World Online.^[1] The name was first published in the Kew Bulletin 13:265 (1958). A later homotypic synonym is Boryangraecum teres (Summerh.) Szlach., Mytnik & Grochocka, published in 2013.^[1] The International Plant Names Index records the original publication details and confirms the authorship and date.^[2] No common names are documented for this taxon.

How to Identify This Species

The available sources describe Angraecum teres only as an “epiphytic subshrub” growing in seasonally dry tropical forest.^[1] Detailed morphological data such as leaf length, flower colour, spur length, or plant size are not provided in the cited references, so precise diagnostic characters cannot be listed here. In the absence of species‑specific illustrations or a full description, identification should be confirmed by comparison with herbarium specimens or expert consultation.

Native Range and Habitat

The species is native to Tanzania, specifically the Eastern Usambara Mountains, which are part of the Eastern Arc Mountains of East Tropical Africa.^[1] It occurs as an epiphyte on trees within seasonally dry tropical forest, a biome characterised by a marked dry season and moderate rainfall during the wet months. Elevational data are not given in the cited sources.

Species‑Specific Care

Because specific horticultural data for Angraecum teres are lacking, growers should apply general practices for forest‑dwelling Angraecum orchids: mount the plant on bark or tree‑fern substrate, provide bright filtered light, maintain moderate to high humidity, and avoid water‑logging. These recommendations are extrapolated from the typical ecology of epiphytic Angraecum species and are not documented for this taxon itself.

Flowering and Pollination

No published information on the timing of flowering, flower morphology, fragrance, or pollinator interactions for Angraecum teres is found in the cited references. Consequently, flowering period and pollination ecology remain undocumented.

Evidence and Limitations

The profile relies on two authoritative taxonomic databases: Kew’s Plants of the World Online and the International Plant Names Index. These sources confirm the accepted name, authorship, publication date, synonymy, and native country (Tanzania). However, they provide limited ecological, morphological, and horticultural details. No peer‑reviewed floras, field studies, or cultivation reports specific to Angraecum teres were located, resulting in several sections marked “Not documented.” Further research, including field observations and herbarium study, is required to fill these gaps.
