Cariniana estrellensis (Raddi) Kuntze

Trees, to 60 m tall, the trunk cylindric. Bark with shallow to deep vertically oriented fissures, the outer bark as thick or thicker than inner bark. Stems sparsely puberulous when young, soon becoming glabrous. Leaves persistent at anthesis; petioles 5-13 mm long, slightly winged, densely pubescent when young, usually pubescent to puberulous at maturity; blades elliptic, 7-11 × 3.5-6 cm, the base subcuneate, decurrent onto petiole, the margins distinctly crenulate to crenate, the apex acuminate, the acumen 2-5 mm long, slightly curved; venation brochidodromous throughout, the midrib plane adaxially, prominent abaxially, glabrous or slightly puberulous abaxially, the secondary veins in 10-19 pairs, prominulous adaxially, prominent abaxially, without domatia at junction with midrib, the tertiary veins oriented randomly or obliquely to secondary veins. Inflorescences usually ramiflorous, infrequently axillary, racemose, unbranched or once-branched , 3-6 cm long, the rachises pubescent, not obviously lenticellate; pedicels 2-5 mm long, puberulous. Flowers zygomorphic, ca. 10 mm diam.; calyx-lobes broadly triangular, 0.8-1.5 × ca. 1 mm, not imbricate, pubescent abaxially, the margins fimbriate, fused at bases to form calycine rim ca. 0.2 mm wide; petals narrowly obovate to narrowly oblanceolate, 4-7 × 2-3 mm, white; androecium fused at base to form short staminal tube, the tube with a reddish spot on inside, markedly prolonged on one side to form ligule, with 50-65 stamens inserted all over adaxial surface of tube and ligule, the filaments 0.4-1 mm long, the anthers 0.2-0.5 mm long, the tube and ligule mostly glabrous adaxially, the ligule white; ovary 3-locular, the style ca. 0.3-0.5 mm long, without stylar collar. Fruits nearly cylindrical but slightly tapered at each end, 6.5-9.5 × 3-3.5 cm, smooth (not costate), the calycine ring inserted ca. 1 cm below apex, the pericarp 2-4 mm thick at apex; operculum 1.5-2.5 cm diam., the opercular rim toothed (muricate). Seeds 12 × 6 mm.
