    Habit
    Scandent to weakly climbing shrub
    Twigs
    Twigs with a layer of branched hairs covering the surface, interspersed with longer patent hairs that are branched at the base only, and densely branched hairs
    Leaves
    Leaves opposite or appearing ternate, very narrowly ovate, 16.5 – 22.5 × 3.5 – 4 cm, margins shallowly dentate, apex strongly caudate, base rounded to asymmetric, upper surface with shorter branched hairs close to the surface and longer erect hairs some of which are branched at the base, these dense along the midrib and venation, lower surface with branched hairs of varying lengths on the venation, venation raised, yellow sessile glands on the surface, occasional peltate scales; petioles 1 – 1.5 cm
    Inflorescences
    Inflorescence axillary, peduncles 2.2 – 2.7 cm, cymes laxly branched
    Pedicel
    Pedicels to 0.5 – 1 mm long
    Bracts
    Bracteoles linear, 2 – 5 mm long Bracts linear c. 7 mm long, indumentum as stems
    Calyx
    Calyx seen only in bud and in fruit, in bud narrowly cupular, 3 mm long, divided into 4 narrowly triangular lobes, c. 0.5 mm long, outer surface with branched hairs covering the surface, interspersed with longer hairs that are branched at the base only, these especially dense on the lobes, inner surface ± glabrous
    Corolla
    Corolla white (Hendrian et al-979), seen only in bud, c. 2.5 mm long, divided into 4 lobes, outer surface glabrous except for a few branched hairs on the back of the lobes, lobes also with yellow sessile glands, inner surface ± glabrous
    Stamens
    Stamens 4, seen only in bud when filaments undeveloped, anthers oblong, c. 1.5 mm long, yellow sessile glands on the connective
    Stigma
    Stigma too immature to describe accurately
    Fruits
    Fruit pink (Lack & Grimes 1809), not seen intact, subtended by the persistent calyx (calyces seen on fruiting specimen have 5 lobes); apparently breaking up into 4 1-seeded pyrenes (seen fragmented, as shown in Fig. 3).
    Distribution
    Apparently endemic to Central and Eastern Central Sulawesi; known from two collections only. Maps 1 and 2.
    Ecology
    Montane evergreen forest; 980 – 1000 m.
    Conservation
    According to the maps of forest condition produced by Cannon et al. (2007), the two collecting localities of Callicarpa mendumiae lie in good forest; this also appears to be the case when satellite images of the area are viewed using Google Earth (Google 2010). There is approximately 120 km between the two localities (measured using Google Earth); forest cover appears to be more or less uninterrupted across the mountainous region between the two areas, perhaps suggesting the range of the species to be quite extensive. I therefore recommend a preliminary conservation assessment of Least Concern.
    Note

    Callicarpa mendumiae appears to inhabit ultramafic areas (Map 2). It would be interesting to ascertain whether this species acts as a hyperaccumulator of nickel as is the case with many other species that occur in ultramafic areas (Proctor 2003).

    This species is named in memory of the late Mary Mendum, botanist at the Royal Botanic Garden Edinburgh, to acknowledge her contribution to our botanical knowledge of Sulawesi through her research on Aeschynanthus (Gesneriaceae) and fieldwork on the island.

    Callicarpa mendumiae is immediately distinctive because of its caudate leaf apices. These are quite unlike any other species in the genus I have seen to date. Both collections are united by this character, coupled with the scandent to weakly climbing habit, and the montane forest habitat. There are some differences between the two collections that are illustrated in Fig. 3: Lack & Grimes 1809 displays an apparently ternate leaf arrangement, but Hendrian et al. 979 has leaves in opposite pairs. The leaves in the latter specimen also have an indumentum of generally shorter hairs. In addition, the Hendrian et al. specimen was collected when the inflorescences were immature, but the Lack & Grimes specimen has a mature fruiting calyx and one fruit. This fruiting calyx appears to be rather an odd feature: it is five lobed. Given that the flower buds seen on Hendrian et al. 979 have four parts, and the fragmented fruit seen on Lack & Grimes 1809 apparently had four pyrenes, I would have predicted the calyx to be four lobed. Further material must been seen to investigate this apparent anomaly.
