CHARACTER DEFINITIONS FOR NEOTROPICAL POLYSTICHUM DATABASE

NSF – 2006

  1. baPESCHU1: color at basal petiole-scale center—NBS Munsell color-chip numbers
  2. baPESCHU2: color at basal petiole-scale edge—NBS Munsell color-chip numbers
  3. baPESCHU3: boundary between basal petiole-scale center and edge—diffuse (0) or sharp (1)
  4. baPESCMG: basal petiole scales conform (0), marginate only at base (1), marginate throughout (2)
  5. baPESCSE1: cilia on basal petiole scales—absent (0), present, (1), abundant (2)
  6. baPESCSE2: cilia on basal petiole scales—short (0), long (1)
  7. baPESCSE3: cilia on basal petiole scales—narrow, weak (0); broad, robust (1)
  8. baPESCtw: basal petiole scales—flat (0), twisted (1)
  9. PRSCSH: pinna-rachis scale shape—character states are length-width ratios viz. 1,5,10,20,30,40
  10. PRSCHU: pinna-rachis scale color—NBS Munsell color-chip numbers
  11. PRSCSE: pinna-rachis scale cilia—absent (0), basal only (1), throughout (2)
  12. LALN: lamina length—metric
