| Field notes | Solitary. Stem ca. 1 m long and 3.2 cm in diameter. The apical part covered by persistent dead leaf sheaths. The stem is light-brown and very hard, while that of G. triglochin is soft. The leaves are irregularly divided with 5-9 pinnae of very variale size (1-17 prominent veins). The rachis of the youngest leaf is 115 cm long, and its petiole is 75 cm long. 12 leaves in the crown. the secondary veins protrude alternately above and below; the veins that protrude below and the rachis are brown-tomemtose abaxially. The leaves do not have tertiary veins perpendicular to the secondary veins, as has G. triglochin. The infructescence has red axes and greenish-brown fruits. The primary axis is 60 cm long, excluding its terminal very slender fertile part, which looks like the secondar/tertiary axes. Basal part is twice branched with only the tertiary axes fertile, while the apical part is only once branched with the secondary axes fertile. The infructescence is infrafoliar being inserted in the axil of a dead leaf sheath well below the crown. 1: lower 1/3 of the youngest leaf. 2: mid1/3 of the youngest leaf. 3: upper 1/3 of the youngest leaf. 4: leaf sheath of another leaf 5: lower part of infructescence. 6: upper part of infructescence. |
