Leaf Shapes - Montessori Botany

Get to know some of the most common leaf shapes and follow-up with a couple of free interactive / printable worksheets for mastery.

Association Montessori Internationale (AMI) has a free set of cards for leaf shapes here (illustrations) and here (photos).

There are actually lots and lots of leaf shapes — some with just minor differences between them — but the following are a few of the most common:

  • Aciculate / acicular – needle-shaped – very narrow and pointed, rounded in cross section
  • Cordate – heart-shaped – pointed apex, 2 rounded basal lobes
  • Elliptic / elliptical – oval, widest at the middle of the blade, with curved margins and a pointed base and apex
  • Flabellate – fan-shaped – semi-circular
  • Hastate – spear-shaped – pointed, shaped like a spear point, with flaring pointed lobes at the base
  • Lanceolate – lance-shaped – long (3-6x as long as it is wide) and widest below the middle of the blade
  • Linear – long and very narrow, margins almost parallel, like a blade of grass
  • Obcordate – reverse heart-shaped – with the stem attached at the tapering end
  • Oblanceolate – reverse lanceolate – much longer than wide, with the widest portion above the middle of the blade
  • Oblong – nearly rectangular, with almost parallel margins, around 2x as long as wide
  • Obovate – teardrop-shaped – reverse ovate – widest above the middle of the blade, with the stem attached to the tapering end
  • Orbiculate / orbicular – circular – with rounded sides
  • Ovate – oval / egg-shaped – with a tapering point, widest below the middle of the blade near the petiole
  • Reniform – kidney-shaped – oval with an inward curve on one side
  • Rhomboid / rhombic – diamond-shaped – widest at the middle and with straight margins
  • Runcinate – oblanceolate with lacerate margins
  • Sagittate – arrowhead-shaped with lower lobes folded downwards or inwards
  • Spatulate – spoon-shaped – broad flat end which tapers towards the base
  • Triangular / deltoid – triangular, shaped roughly like an equilateral triangle (“deltoid” because it is shaped like the Greek letter delta)
