Lasianthus stipularis Blume var. novoguineensis Valeton (1911) View in CoL 498, syn. nov. — Type: Versteeg 1228 (holo L; iso K), SW New Guinea.

Shrubs, 1– 2 m high, entirely glabrous except bracts and corolla; branchlets terete, 2 –3 mm diam, compressed in the youngest part. Leaves: blades oblanceolate-oblong, 12–16 by 3 – 5.5 cm, membranaceous, greenish brown when dry, apex cuspidate-caudate, base cuspidate-cuneate, midrib and nerves flat to slightly prominent above, prominent beneath, nerves 9–10 pairs, slender, ascending at an angle of over 50°, curved to the margin, nervules faint, subparallel; petioles 5–10 mm long; stipules broadly triangular-ovate, ovate or ovate-orbicular, larger, covering the cymes, up to 1.25 cm long and broad at base, membranaceous, glabrous, persistent. Cymes sessile; bracts numerous, linear to narrowly lanceolate, villous, up to 1.5 cm long, often exceeding the stipules. Flowers sessile; calyx campanulate, teeth broadly triangular, c. 1 mm long, hirsute; corolla not seen. Drupes ovoid-globose, glabrous, 4–5 mm diam, crowned with calyx limbs, with 4 obtuse ridges; pyrenes 4.

Distribution — Burma, Thailand, Malaysia (Peninsular, Bor- neo), Brunei, Indonesia (Sumatra, Java, Kalimantan, Sulawesi, Moluccas), Philippines, Papua New Guinea.

Note — This species has numerous hairy linear to narrowly lanceolate bracts up to 1.5 cm long, in which it differs from L. pseudostipularis (bracts minute and inconspicuous). Lasianthus stipularis var. novoguineensis differs from the typical variety by only having oblong to elliptic-lanceolate leaves, which is not enough to separate it from L. stipularis as a variety of the latter.
