Description
Species Description - Dioecious shrub or treelet, 1-8 (rarely to 16) m tall; young branchlets subangular or terete, subglabrous or sparsely stellate-pubescent. Leaves in whorls of 3 or opposite; petioles 0.7-5 cm long; lamina drying reddish brown, oblanceolate to obovate, rarely broadly elliptic, coriaceous, 8-14(-26.5) X 2.7-5 (-11) cm, the base and apex acute to obtuse, the tip 0.5-0.8 cm long, leaves above and below with few minute appressed stellate to sublepidote hairs, occasionally glabrescent, young leaves above sometimes with conspicuous appressed silvery stellate-lepidote hairs, with 9-12 pairs of secondary veins, these flat above, distinctly raised below, the margin serrulate or serrate. Cymes 2.5-4 cm long and often pendent, pubescent like the young branchlets, with 10-15 flowers. Fresh flowers greenish yellow or whitish; male floral cup broadly obconical to semiglobose, 2-2.9 mm in diam., 1.5-2.5 mm high, glabrous except for a few appressed bifid or few-branched hairs, the tepals 4-5(-6), narrowly oblong to almost spatulate, 2-4 mm long (Fig. 46b), the floral roof distinctly raised, and glabrous; stamens 9-12; female floral cup subglobose, 3.5-4 mm in diam., 3-3.5 mm high, the pubescence as in the male flowers, the tepals triangular or broadly triangular, ca. 1.4 mm long, the floral roof raised to a cylindrical bulge separated by a groove from an acute central tube sheathing the styles (Fig. 46f), drying dark brown; styles 2-5. Fruiting receptacle 1-1.5 cm in diam., globose and usually with minute (less than 1 mm long) blunt protuberances basally, when fresh and mature red with small cream spots (lenticels) and a strong lemon smell; drupelets 1-3, each with a sty lar aril.

Discussion
Siparuna lozaniana is distinguished by oblanceolate to obovate coriaceous leaves (often in whorls of three) with a sparse indumentum of appressed few-branched to sublepidote hairs. It has rather small fruiting receptacles that may be smooth or have a few short, blunt tubercles. The sole collection from Mag- dalena (Kirkbride 2411) resembles the central Andean material in all aspects.

Distribution
Siparuna lozaniana is restricted to the eastern Andean cordillera in central Colombia, occurring mainly in Santander, Boyacá, Cundinamarca, and adjacent Meta where it grows in humid montane forest or cloud forest at 1600-2900 m elevation. Flowering and fruiting throughout the year.
