title: Table 1 in Systematic relevance of pollen morphology in tribe Hylocereeae (Cactaceae)

description: Table 1. Qualitative and quantitative morphological characters of pollen for the representative species in the tribe Hylocereeae. Spinule length and perforation diameter are coded based on the simple gap method by Almeida and Bisby (1984). PE ratio =Polar axis/Equatorial Diameter; PAI ratio =Apocolpium/Equatorial diameter in polar view (Polar Area Index); Amb: Outline in polar view. Spinule length (0 = 0 µm, 1 = 0.33-0.78 µm, 2 = 1.27-1.86 µm); Perforation diameter (0 = 0.11-0.18 µm, 1 = 0.23-0.72 µm). P=present, A=Absent.
