Leaves alternate, spiral or distichous; petiolate or subsessile
, presence of pulvinus; extrafloral nectaries absent or present, convex, sessile or stipitate, located between the pairs of leaflets or on the petiole; leaflets 1-many pairs, papyraceous to coriaceous, elliptic to oblong, lanceolate to obovate, apex acuminate, rounded to mucronate, base oblique.
5 cm long, oblong in outline; petioles 10-12 mm long, winged, somewhat aromatic when crushed; rachis more narrowly winged than petiole, involute when drying, and appearing quadrangular; leaflets 7-11, 5-6 x 6-9 mm, subsessile
, semi-succulent, and broadly obovate to broadly elliptic, yellowish-green, opaque, midvein on abaxial surface prominent; indument spiculate on stems, reproductive structures glabrous, foliage with resinous papilla.
, pedicel < 1 mm long, axillary to the 3-4 most distal bracts.
Leaves are sessile or subsessile
(in most Berberis spp.
In studies about insect-plant interactions developed at the National Park of Restinga de Jurubatiba (PNRJ), Rio de Janeiro, we observed very remarkable leaf mines on Erythroxylum subsessile
disposed in close-set arrangement that give the shoots a "fern-frond" appearance (Wiehler 1983), and flowers that have external appendages between the corolla lobes as it occurs in some species of sect.
5 cm, persistent, only slightly flattened at base; blade oblanceolate, 2-5 mm wide, entire or serrulate, puberulent at margin; lowermost cauline leaves shortly petiolate to subsessile
, not auriculate at base; middle and upper cauline leaves entire or few toothed, oblong, minutely auriculate at base.
5-3 cm apart, the lateral branches 6-9 cm long, erect or nearly so at the base and subspreading toward the apex, subdensely to densely flowered at anthesis, with 4 to 6 flowers, bearing sterile bracts at the apex, rachis geniculate, slightly angulose, 3-8 x 3 mm, glabrous, green, stipes 7-30 x 5 mm, erect or nearly so, slightly complanate, green, glabrous, ebracteate, the terminal branch erect or nearly so, similar to the lateral branches, subsessile
Umbels concave, flat or convex, with a variable number of rays, pedunculate, rarely subsessile
Flowers closely disposed, initially subsessile
, then pedunculate; pedicles 1-2 mm long.
The petioles are very short (4-5 mm versus 10-80 mm in the other species) and the bracts and upper leaves are subsessile
Aechmea nudicaulis, Clusia hilariana and Erythroxylum subsessile
probably take advantage of the arrival to favorable microhabitats, not by the gut effect on the seeds.
