| 英文摘要 |
Two new species of Pentaphragma (Pentaphragmataceae), P. bicolor and P. pendula, from Sarawak are described and illustrated. Pentaphragma bicolor resembles that of P. prostratum (Kiew, 1990) but is different in the stellate hairs (vs. glabrous) leaves, shorter petioles 0.5–2 cm long (vs 2.5–6(–13) cm long), erect (vs. deflexed) inflorescence with sessile or subsessile (vs. 10–15 mm long) peduncle and retuse (vs. apiculate) anther apices. Pentaphragma pendula is also similar to P. longisepalum (Kiew, 1990), but differs in its suborbicular (vs. elliptic) leaf shape, petioles to 3 (vs. to 9) cm long, inflorescence deflexed (vs. erect) with up to 12 flowers (vs. to 10 flowers), bracts to 3.5 × 1.5 cm (vs. 1–1.6 × 0.6–0.9 cm), corolla with recurved (vs. non-recurved) lobes. |
