Angraecum curvipes

Angraecum curvipes Schltr. is an accepted orchid species recorded by Kew Plants of the World Online as native to Cameroon, where it is described as an epiphytic subshrub of wet tropical forest [1]. It is a member of Orchidaceae and has been placed in alternative genera as Angraecoides curvipes and Conchograecum curvipes [1][2]. The available evidence is strongest for nomenclature and distribution; species-specific morphology beyond stem and leaf arrangement, habitat detail, cultivation requirements, and pollination are not well documented in the supplied sources.

Names and Taxonomy

Angraecum curvipes Schltr. is the accepted name in Plants of the World Online [1]. The basionym was published in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 38: 21 (1905) [1]; IPNI records the place of publication as 38(1): 21, descr. and gives the family as Orchidaceae [2]. The authorship is Schltr. [1][2]. The requested title includes (Cameroon); that is a geographic qualifier, not part of the scientific name.

POWO lists two homotypic synonyms: Angraecoides curvipes (Schltr.) Szlach., Mytnik & Grochocka (2013) and Conchograecum curvipes (Schltr.) Szlach., Grochocka, Olędrz. & Mytnik (2018) [1]. These are alternative generic placements of the same species, not separate species. No common name is documented in the supplied sources. The name status is accepted under the Kew POWO treatment used here; other taxonomic opinions may exist but are not documented in the supplied evidence.

How to Identify This Species

Kew POWO describes Angraecum curvipes as an epiphytic subshrub [1]. A French Wikipedia page excerpt adds that it is an epiphytic herb with a 10 cm-long, densely leafy stem, distichous leaves, and oblong-ligulate leaves with an apex described in the excerpt as “unequally” before the text is cut off [4]. That excerpt is not a full morphological treatment, and the truncated leaf-tip description should not be completed by inference.

Flower dimensions, lip and spur shape, color, fragrance, and flowering measurements are not documented in the supplied reliable sources. A horticultural aggregator snippet lists a 30 cm height, white to greenish-white flowers, fragrance, and year-round bloom [5], but it provides no growing context and conflicts in scale with the 10 cm stem in the Wikipedia excerpt [4]; those values are therefore treated as unverified rather than diagnostic. Identification from a label or a single photograph is unsafe for this species because the available description is incomplete. A confident determination should rely on verified botanical material and a full description or key that includes floral parts.

Native Range and Habitat

Kew POWO gives the native range as Cameroon and describes the species as growing in the wet tropical biome [1]. It is recorded as an epiphytic subshrub [1]. The supplied Kew source does not give an elevation range, host-tree data, or seasonal habitat notes. A French Wikipedia excerpt reports the species as endemic to Cameroon and the continental region of Equatorial Guinea [4], which conflicts with the Cameroon-only range in the Kew POWO snippet [1]. The supplied evidence does not resolve whether this reflects a taxonomic concept difference, an updated distribution, or an error in the secondary source. No introduced or cultivated occurrence is documented in the supplied sources.

Species-Specific Care

No species-specific cultivation protocol is documented in the supplied sources. The table below therefore separates the few supported facts from missing guidance rather than supplying a generic Angraecum schedule.

The only defensible cultivation statement from the supplied evidence is that Angraecum curvipes is epiphytic and native to a wet tropical biome [1]. That does not justify constant moisture, a particular humidity percentage, a specific temperature setpoint, or a dry rest. A NativePlants.info snippet lists low drought tolerance and year-round bloom [5], but it gives no location, growing conditions, or primary evidence, so it is not sufficient for care recommendations. Growers should look for provenance-linked cultivation records before treating any schedule as species-specific.

Flowering and Pollination

Species-specific flowering months, flower longevity, fragrance timing, nectar-spur dimensions, and pollinators are not documented in the supplied reliable sources. A NativePlants.info snippet lists bloom months from January through December and fragrance as yes [5], but the source is an aggregator and the snippet does not state a location, hemisphere, or growing context; it cannot establish a flowering calendar for this species. The French Wikipedia excerpt does not supply flowering data [4]. Pollination is not documented in the supplied sources. Flower shape alone should not be used to name a pollinator, and no pollinator observation is available here.

Conservation and Responsible Cultivation

An IUCN Red List assessment for Angraecum curvipes by Simo, Stévart and Droissart was published in 2016 [3]. The supplied IUCN snippet confirms that an assessment exists but does not state the category. A French Wikipedia excerpt reports the status as Endangered, EN B2ab(i,ii,iii,iv,v) [4]. Because that is a secondary excerpt and the primary IUCN snippet is incomplete, the category should be confirmed against the full assessment before being repeated as a formal status. No CITES listing, national legal status, or trade-compliance information is supplied here; a nursery purchase should not be assumed to be legally compliant without evidence.

Evidence and Limitations

This profile is based on search snippets and short page excerpts, not on full papers or complete floras. The Kew POWO and IPNI snippets support the accepted name, authorship, publication, synonyms, native range, and epiphytic subshrub habit [1][2]. The French Wikipedia excerpt supplies a partial stem and leaf description and a conflicting range report [4]. The IUCN snippet confirms an assessment but not its category [3]. The NativePlants.info snippet contains unverified height, flower-color, fragrance, bloom-calendar, and drought-tolerance claims without growing context [5]. Material gaps remain for floral morphology, elevation, host-tree relationships, habitat seasonality, cultivation temperature, light, watering, humidity, airflow, potting, feeding, repotting, flowering behavior, pollination, and the formal conservation category. The draft has not been botanically reviewed and should not be treated as a verified cultivation guide.
