Claim: Pinguicula filifolia has leaves that are approximately 4–6 mm long and 1-1.5 mm in width with usually erect leaves while seedlings that arise from resettes that are 8-10mm in diameter where a single rosette typically has 4-6 blades sprouting from it.
Evidence: Pinguicula filifolia has leaves that are approximately 4–6 mm long and 1-1.5 mm in width with flat or sub-erect leaves while seedlings. These blades arise from rosettes that are 8–10 mm in diameter. A single rosette typically has 4-6 blades sprouting from it.
