Discussion
8. E. gummiferum (Martius) Macbride (Mesquita, 1990: 137, figs. 25-27). In the field, E. gummiferum is notable for corky, deeply fissured trunks and branches, a feature common in cerrado climax. Almost all specimens are instantly recognizable by the low leaf- formula (i—)ii—iii/4—6(—7), or by the massive velutinous pod with mealy-fibrous, nonresinous valves, or by both. We have, however, two ambiguous collections: from Xavantina, Mato Grosso, Irwin & Soderstrom 6369 (fl., NY), with leaf-formula to iii/12, suggesting passage into E. maximum; and from BR-364, km 80 NE of Cuiabá, Mato Grosso, Cid & al. 4449 (fl., fr., NY), with leaves of typical E. gummiferum but a glabrescent pod heavy with resin. These obviously need further observation.
