Description.

Hermaphroditic trees, reproductive height 15-38 m. Trunk 35-65 cm diam.; outer bark grayishbrown, rough, shallowly to deeply fissured, with vertical stripes of raised lenticels; inner bark red and whitestriate. Trichomes of three types: white, flexuous to uncinate or suberect hairs to 0.3 (0.4) mm long (on leaves); capitate glandular hairs; and yellow, appressed to suberect, blunt glandular trichomes to 0.2 mm long (on inflorescences). Leaves (5) 7-13jugate, 20-33 cm long; petiole 3.1-5.6 cm long, petiole and rachis with dense flexuous to uncinate hairs; lateral petiolules 1-2 mm long, the terminal one 0.7-1.7 cm long, petiolules with hairs as on rachis; basal leaflets 2.9-3.8 × 1.5-2 cm, obliquely ovate to broadly elliptic, other laterals 5.2-7.6 × 1.6-2.3 cm, obliquely lanceolate to elliptic, terminal leaflet 5.5-5.9 × 1.4-1.8 cm, oblanceolate to elliptic; leaflet apex acuminate, acumen 4-13 mm, glandular-mucronate; lateral lamina medially and basally asymmetrical; acroscopic side rounded to obtuse, basiscopic side acute; basal insertion sometimes asymmetrical and slightly decurrent; leaflet margin often slightly revolute, subentire to sparsely serrate, the teeth concave-convex with acute (sometimes spiculate) apex; leaflets chartaceous to membranaceous, both surfaces dull Inflorescences (pseudo-)terminal, produced with new flush of leaves, ca. 9-17 cm long, secondary axes 5-8 cm long, axes with scattered to dense hairs and sparse to scattered appressed glandular hairs; bracts subtending secondary and higherorder axes 0.5-0.6 mm long, bracteoles 0.25-0.4 mm long, all bract(eole)s lanceolate to narrowly ovate, sparsely pubescent to glabrous, the margin with sparse glandular hairs; pedicel 1.5-1.7 mm long overall, portion distal to articulation 1.25-1.3 mm long, with scattered hairs. Calyx 0.6-0.9 mm long overall, aestivation apert, divided nearly to base, 0.4-0.6 mm long, deltate, margin entire to slightly erose; petals ca. 2-2.5 × 0.9-1.2 mm, narrowly ovate to elliptic, acute, greenish white, glabrous or with a few scattered hairs, reflexed at anthesis; stamens spreading, antesepalous and antepetalous ones 2.4-3 and 1.5-2.7 mm, respectively, the anthers 0.7-1.2 mm long, in dorsiventral view oblong-ovate, in lateral view oblong-elliptic; disk 0.75-0.8 mm tall, 0.15-0.2 mm thick, summit craggy and outer margin deeply sulcate, yellow; on recently opened flowers the pistil 1.3-1.6 mm long, cylindrical to slightly ovoid overall, divided ca. half its length into thickly subulate, apically divergent styles 0.6-0.8 mm long, the stigmas extrorse, obovate.

Distribution.

Spondias testudinis is endemic to southwestern Amazonia in Acre, Brazil and nearby portions of Bolivia (Pando) and Peru ( Huánuco, Ucayali).

Ecology.

This species occurs in lowland dry to wet tropical forest on terra firme, elev. 200-780 m. It is known to flower in Sep-Oct and to fruit Feb-Jun.

Conservation status.

We classify this species as of Least Concern; although it has a more limited geographic distribution than most of its congeners, it is relatively common where it occurs in SW Amazonia, and that region is still mostly forested.

Discussion.

Spondias testudinis closely resembles Spondias macrocarpa because both have leaves (5) 7-13-jugate, the leaf rachis densely pubescent; intersecondary veins sometimes present, parallel to secondaries and with admedial branching; anthers 0.7-0.9 mm long (to 1.2 mm in Spondias testudinis ), and the disk much taller than thick. The former is distinguished by the following characteristics: leaflet teeth spiculate (vs. not), secondary veins 15-17 (vs. 10-15) pairs; pedicel 1.5-1.7 mm (vs. 2.5-3.5 mm) long; and fruits (3.8) 4.9-6.3 cm (vs. 3.5-4.2 cm) long.

It differs from the sympatric Spondias mombin by a number of features, including the following: trichomes on leaves flexuous to uncinate or sub-erect (vs. always straight), to 0.3 (0.4) mm (vs. to 0.2 mm); leaves (5) 7-13-jugate (vs. 3-7-jugate), the midvein on adaxial side sparsely or more often densely pubescent (vs. glabrous or sometimes with trichomes on midvein and secondary veins); fruit surface lenticellate (vs. smooth); eophylls on seedlings imparipinnate, 2-3jugate (vs. trifoliolate) and the eophyll leaflets lanceolate (vs. ovate) and laciniately (vs. simply acutely) serrate ( Spondias mombin seedlings described and illustrated in Vogel 1980).
