  Other markings on berry

  the ripe fruits are mostly one color without spots or streaks

• Glands or sap

  Sap

  the sap is clear and watery

• Growth form

  Underground organs

  Leaf arrangement

  alternate: there is one leaf per node along the stem

  Leaf blade basal lobes

  the leaf blades do not have basal lobes

  Leaf blade base

  the leaf has a distinct leaf stalk (petiole)

  Leaf blade base shape

  the base of the leaf blade is cuneate (wedge-shaped, tapers to the base with relatively straight, converging edges), or narrow

  Leaf blade cross-section

  the leaf blade is more or less flat in cross-section

  Leaf blade faces

  both surfaces of the leaf blade are exposed

  Leaf blade form

  Fully-formed (i.e., expanded), +/- green leaf blades are found somewhere on the plant

  Leaf blade length

  70–125 mm

  Leaf blade shape

  • the leaf blade is elliptic (widest near the middle and tapering at both ends)
  • the leaf blade is lanceolate (lance-shaped; widest below the middle and tapering at both ends)
  • the leaf blade is ovate (widest below the middle and broadly tapering at both ends)

  Leaf blade surface colors

  the upper side of the leaf blade is relatively uniform in color

  Leaf blade veins

  the lateral veins are parallel or slightly arched in the direction of the tip
