Pholidostachys synanthera subsp. robusta Informationen

Identification:
Stems 2.6(1.0-6.0) m long, 5.6(3.0-22.0) cm diameter, solitary. Leaves 15(4-27) per stem; sheaths 32.8(15.0-74.0) cm long; petioles 70.1(24.0-136.0) cm long; rachises 74.1(48.0-91.0) cm long, 8.1(3.6-12.6) mm diameter; pinnae 7(4-12) per side of rachis; basal pinna 49.6(26.5-67.5) cm, long, 1.7(0.2-7.6) cm wide, forming an angle of 50(27-72)� with the rachis; apical pinna 45.0(23.0-65.0) cm long, 10.5(2.5-22.5) cm wide, forming an angle of 15(9-24)� with the rachis. Inflorescences branched 1-2 orders, with a welldeveloped peduncle and rachis, and several rachillae, these spreading at anthesis; prophylls and peduncular bracts woody, not covering rachillae at anthesis; prophylls 38.0(25.5-55.0) cm long; peduncular bracts 32.1(19.0-41.0) cm long, inserted 8.6(5.0-12.5) cm above the prophyll; peduncles 44.8(20.0-70.0) cm long, 11.4(5.3-19.1) mm diameter; rachilla 12(4-25), 28.5(14.0-56.0) cm long, 6.1(3.7-10.3) mm diameter; proximal lips of flower pits regularly shaped, rounded, not covering pits before anthesis, recurved fruits scarcely compressed, ellipsoid, with obscure longitudinal ridges, 14.3(10.2-17.7) mm long, 8.4(6.1-10.5) mm diameter.

Allgemeine Informationen:
11 variables (stem height, stem diameter, leaf number, rachis length, rachis width, number of divisions, basal pinna length, basal pinna angle, apical pinna length, apical pinna width, rachillae width) are significantly different from other Pholidostachys synanthera.
