Taxonomy
2 Hallier 624 (with male fl., Mt Damoes, W Kalimantan) is obviously close to H. valida, but markedly differs, and apparently represents a new, yet undescribed species. The specimen is discussed further by De Wilde, I.e. Female flowering specimens which match Hallier 624 have not been found as yet, but Afriastini (& Burley) 579 (in fruit, from Kalimantan) is possibly identical; it has the perianth not persistent under the fruits.
1 The sterile specimen Dumas 1649 (Palembang, 200 m alt.) deviates from the other specimens (all from 900-1100 m alt.) by the shorter indumentum on the leaf bud (hairs only 0.3 mm long).
