    Species Description - Shrub or small tree to 3 m, rarely taller, young shoots puberulous, rarely subglabrous. Leaf blade narrowly obovate to oblanceolate, sometimes elliptic. 13-47 x 6-17 cm, coriaceous or subherbaceous, 0.12-0.23 mm thick, glabrous or glandular-pilose beneath, base attenuate, apex acute or short-acuminate, sometimes obtuse, margins entire or serrulate, lateral veins conspicuous beneath, rather inconspicuous above, surfaces between veinlets striate beneath, striate, furrowed or smooth above; extraxylary sclerenchyma adjacent to epidermis on both sides, abaxially arranged in bundles 3-12 cells thick, adaxially in somewhat flattened bundles 3-10(-13) cells thick or in a more or less continuous layer 1 or partly 2 cells thick, hypoderm lacking; petiole 2.5-12 cm long, 0.9-3.5 mm thick, mostly puberulous at base. Racemes in male and bisexual plants to 31 cm long with 15-60 flowers, in female plants 1-3.5 cm long with 7-15 flowers, rachis in male and bisexual plants 0.5-1 mm thick, in female plants 0.7-1.6 mm thick, glabrous or puberulous; pedicels (0.5-)l-2(-3) mm long; bracts 0.5-1 mm long, inserted at nodes. Flowers 4- or 5-merous, calyx lobes very broadly ovate, (1-) 1.7-3 x (1.5-)2-3 (-3.2) mm; corolla orange or orange-red, tube 1.5 2 (-2.5) mm long, lobes (1.5-) 1.7-3 x (1.5-)2-3(-3.2) mm. Stamen filaments glabrous, in male and bisexual flowers fused into a tube 0.5-1.2 mm long, in female flowers free, 0.5-0.7 mm long. Pistil in male flowers lacking or linear, in bisexual flowers sublinear with 1-3 ovules, in female flowers ovoid with 8-16 ovules in 2 or 3 rows; stigma in bisexual flowers often 2-lobed. Fruit orange or orange-yellow, 1.5-3(-4) cm diam., pericarp 0.3-0.4 mm thick, surface smooth; seeds 2-8(-13), (6-)7-9.5(-l 1) mm long.

    Distribution and Ecology - Throughout W Amazon (Fig. 41) in terra firme rain forest and extending into premontane and lower montane forests up to 1300 m. Flowering primarily Aug-Oct, but several records in Apr-May; mature fruits throughout most of year, but especially Aug.

  • Discussion

    Clavija weberbaueri is the most commonly encountered species of Clavija in the western Amazon. It is characterized by puberulous, young shoots; small to medium-sized leaves with relatively long petioles; and small and often (but far from always) 4-merous, short-pedicellate flowers.

    The broad circumscription of Clavija weberbaueri advocated in earlier works (Stâhl 1990, 1991) has been retained in the present treatment, even though the combination of character traits, e.g., number of floral parts, disposition of adaxial foliar sclerenchyma, and leaf pubescence, is bewildering. Further studies focusing on population structure and variation along ecological gradients may contribute to a better understanding of this taxon.
