    Note
    Shrub to tree, glabrous throughout. Petioles (8 –) 10 – 20 mm long. Leaf margin eglandular or, if glandular, then glands (or their scars if caducous) only on distal half. Corolla lobes 5 or 6, patent to slightly ascending. Drupe 5 – 6.5 × 3 – 3.7 mm. Fruiting calyx lobes not exceeding disc. Endocarp 0.05 – 0.1 (– 0.2) mm thick.

    Symplocos inopinata is distinguished from other species of Symplocos sect. Hopea by the combination of petioles (8 –) 10 – 20 mm long with at least some on each individual > 10 mm, eglandular leaf margin or, if glands present, glands or gland scars distributed only on the distal half of the margin, disc in longitudinal view concave, subconical or rarely flattened in the staminate flower and conical or subconical in the pistillate flower, drupe 5 – 6.5 × 3 – 3.7 mm, fruiting calyx lobes 0.2 – 0.5 (– 0.6) mm long and not exceeding the disc in length, and endocarp 0.05 – 0.1 (– 0.2) mm thick.

    The epithet “inopinata” is Latin for “unexpected”.

    Symplocos oblongifolia is one of the most widespread and polymorphic species of Symplocos in Brazil (Aranha Filho 2008). Like S. inopinata, it is found in the southern portion of Chapada Diamantina. It can be distinguished from S. inopinata by pistillate flowers with a flattened to rarely short-cylindrical disc in longitudinal view (vs conical or subconical in S. inopinata), drupe (8 –) 8.5 – 14 mm long (vs 5 – 6.5 mm long) with an endocarp 0.4 – 0.8 mm thick (vs 0.05 – 0.1 [– 0.2] mm thick), and fruiting calyx lobes 0.5 – 1.5 mm long (vs 0.2 – 0.5 [– 0.6] mm long). Moreover, specimens of S. oblongifolia collected in Chapada Diamantina have petioles 3 – 8 mm long or rarely reaching 10 mm, whereas those of S. inopinata consistently have at least a few petioles > 10 mm long.

    In overall morphology, Symplocos inopinata resembles S. rhamnifolia A. DC. and S. oblongifoliaCasar. (long known as S. lanceolata A. DC.). Like S. inopinata, S. rhamnifolia grows in gallery forest and in humid soils, and is endemic to Chapada Diamantina (although limited to the northern portion). It can be differentiated from S. inopinata by consistently glandular leaf margins, with glands or gland scars present on the distal ¾ (vs eglandular, or glands or gland scars present only on the distal half) and fruiting calyx lobes always exceeding the disc (vs not exceeding the disc). In addition, S. rhamnifolia has petioles (3 –) 4 – 8 (– 10) mm long (vs [8 –] 10 – 20 mm long, but always some individuals > 10 mm long), disc in longitudinal view always flattened in the staminate flowers (vs concave, subconical or rarely flattened), and drupe 3.5 – 5.3 mm wide (vs 3 – 3.7 mm wide).

    Distribution
    The species is restricted to the southern part of Chapada Diamantina in the state of Bahia.
    Ecology
    Symplocos inopinata typically occurs in gallery forest, ombrophilous forest, or campo rupestre (rocky fields) mixed with ombrophilous forest but can also be found in rock outcrops where it thrives in sandy and humid soil, at 1000 – 1750 m elevation or rarely below 1000 m.
    Conservation
    Due to its estimated range of less than 5000 km2 and habitat loss, we categorise Symplocos inopinata as endangered (EN: B1b[iii]).
    Phenology
    Flowering specimens of Symplocos inopinata were collected from March through August and fruiting specimens from April through July.
