Description

Species Description - Shrubs or trees to 10 m. Branchlets 5 cm below terminal bud 2-3.2 mm in diam., ± irregularly angular, with (moderately) dense cover of very short and fewer longer (up to 0.3 mm), appressed hairs, older twigs becoming roundish, die indument becoming grey and felted, very slowly glabrescent; terminal buds sprouting at anthesis, densely covered with appressed, light brown hairs. Petioles 5-9(-13) mm long, 1-2.2 mm thick, irregularly roundish to almost triangular below, often higher than wide, canaliculate above, indument ± as on twigs. Leaves alternate, oblanceolate to lanceolate-elliptic, widest ca. at the middle to 3/5 from the base, 5-11.5 cm long, 1.4-4.5 cm wide, 2.5-3.5(-4.6) times longer than wide, tip short acuminate or occasionally acute, base cuneate to attenuate, margin narrowly recurved to narrowly revolute, midrib ± impressed above, prominent below, secondary veins slightly impressed to ± level above, prominent below, 5-7 pairs, diverging at 30-45(-60)°, in mid-lamina running at an angle of 15-30(-40)° to the midrib, tertiary venation mainly percurrent to scalariform, occasionally with small laterally oriented intersecondaries, usually rather inconspicuous, ± level above, (very) slightly raised below. Indument consisting of ± moderately short (ca. 0.1-0.3 mm), appressed to ascending hairs (but see below), initially moderately sparse on both sides, soon glabrescent above, subglabrescent below except for the barbellate axils of lateral veins. Gland dots rarely visible, only in youngest leaves. Inflorescences for the most part inserted in the axils of cataphylls on the basal part of the young growth, but usually also some of them in the axils of young leaves, 0.7-2 mm in diam. at the base, on a twig of 1.3-4 mm diam., 4-13.5 cm long, reaching ca. 2/3 to 1½ the length of foliage leaves, (frondose inflorescences occasionally much larger); peduncle 1.8-4.5 cm long, i.e., ca. 1/3 to almost 1/2 the length of the inflorescence, lateral branches 0-6 below terminal cluster of cymes, usually branched twice (in Gibbs 6668 botryoid except for the terminal cluster), indument consisting of ± short (ca. 0.10.3 mm), appressed to ascending hairs, moderately sparse to moderately dense on peduncle, + dense on receptacle. Pedicels (1.5-)2.5-5.5(-8) mm long, 0.3-0.8 mm thick. Flowers 5-6.5 mm in diam., tepals ± elliptic, 1.9-2.8 mm long and 1.5-2 mm wide, papillosity ± fine and short on the inside surface, ± moderately dense. Stamens ca. 1-1.3 mm long including a distinct filament of 0.2-0.4 mm, anthers ± papillose (often weakly) at the tip, in the first whorl broadly pentagonal with a ± obtuse tip, in the second whorl pentagonal to ovate with an obtuse to narrowly parabolic tip, in the third whorl roundish-obtrapeziform with a broadly obtuse to truncate tip. Staminodes slightly clavate, reaching ca. 1/3 to 1/2 the length of the stamens, papillose-hairy on abaxial side, glandular on adaxial side, free or nearly so. Pistil ca. 1.6-2.2 mm long, glabrous, ovary ± ellipsoid, style ca. as long as the ovary or somewhat shorter. Receptacle relatively open, shallowly bowl-shaped, glabrous inside. Berry (after Guillemin 1339) ellipsoid, ca. 13 m long, ca. 9 mm in diam., cupule deeply bowl-shaped, ca. 4 mm high and 7 mm in diam., pedicel slightly but increasingly thickened towards the cupule.

Discussion

Nectandra barbellata is closely related to N. puberula, and it may eventually be placed in synonymy of that variable species. At present I prefer to keep it separate because it has most of its inflorescences arranged along the basal part of the young growth, its young twigs have a different kind of indument, its older twigs are stouter, and its anthers are relatively less prolonged beyond the pollen sacs and less papillose. None of these characters, however, is without intermediates, and among the collections included here only the three Hoehne collections appear nearly identical. The only fruiting specimen, Guillemin 1339, might as well be placed in N. puberula, since most of its peduncles come from the axils of leaves and the other characters are difficult to assess in fruiting material. Gibbs 6668 differs by having the midrib of its leaves not distinctly impressed above, and by (almost) botryoid inflorescences. Hatschbach 49979 from Espirito Santo has slightly larger leaves than the collections from S3o Paulo, and frondose inflorescences. It also resembles Hatschbach 49908 (MO), a collection of uncertain affinity from the same state, somewhat similar to N. globosa.

Common Names

canela, Canela amarela, Canela parda

Distribution

Known only from five collections from the state of São Paulo, Brazil, plus one (two ?) from Espírito Santo. At least the latter comes from rainforest. Flowers September to October.
