Angraecum modicum

Names and Taxonomy

The accepted scientific name is Angraecum modicum Summerh. The name was first published in Kew Bulletin 13:84 (1958) ^[2]. POWO lists the name as accepted and records Liberia as its native range ^[1]. A homotypic synonym, Angcoecoides modica (Summerh.) Szlach., Mytnik & Grochocka, appears in later literature but refers to the same taxon ^[1]. No common name is documented in the consulted sources.

How to Identify This Species

Angraecum modicum is a miniature to small epiphytic subshrub, typically reaching about 30 cm in height ^[4]. The stem is erect to arching and is sheathed by several clasping leaf bases. Leaves are distichous, narrow‑lanceolate, slightly bilobed at the apex, coriaceous, with a prominent mid‑nerve and a curved margin ^[3]. The inflorescence is a short, thin peduncle (0.28–1 in, 7–25 mm) bearing three flowers ^[3]. Flowers are flesh‑coloured according to POWO ^[1] and described as white to greenish‑white on NativePlants.info, with a fragrance noted as present ^[4]. The labellum lacks a pronounced constriction and tapers gradually to the apex, distinguishing it from the similar Angraecum angustum which has a cordate front part of the labellum and a constricted spur ^[3]. The spur is a narrow cone that narrows progressively from base to apex.

Native Range and Habitat

The species is endemic to Liberia, situated in West Tropical Africa ^[1][5]. It occurs in lowland plains up to about 400 m elevation, growing as an epiphyte on tree trunks in wet tropical forest biomes ^[3][6]. The habitat is characterised by high humidity and consistent moisture, typical of the West African rainforest.

Species‑Specific Care

Because specific horticultural studies are lacking, growers should treat A. modicum as a warm‑growing epiphyte, providing good air circulation, frequent but not water‑logged watering, and a humid environment that mimics its native rainforest conditions.

Flowering and Pollination

Flowering has been recorded from June through September in its native range ^[4]. Flowers are fragrant and display a flesh‑to‑white coloration, with a relatively short inflorescence. No pollinator has been documented for this species; the morphology (long narrow spur) suggests moth pollination, a common trait in the genus, but this remains unverified for A. modicum.

Conservation and Responsible Cultivation

Angiosperm Extinction Risk Predictions classify the species as “Threatened” with a confident assessment ^[6]. The limited distribution and habitat specificity underline the importance of sourcing plants from reputable, legally compliant growers and supporting conservation of West African rainforests.

Evidence and Limitations

Key aspects such as precise light requirements, temperature ranges, and detailed pollination biology are not documented in the available sources. Future field studies and horticultural trials are needed to fill these gaps.
