""N. clipeata" is one of the most aberrant and striking species of its genus. Especially the almost orbicular leaves, the thick, short, never curved tendrils, which are inserted far from the apex, the peculiar-shaped pitcher without wings and the strongly vaulted lid are very remarkable. A leaf form as aberrant as this, only occurs in the Philippine species "N. truncata". It is not known, in what manner "N. clipeata" grows. The following seems probable to me. The plant does not climb. The short and robust stems, petioles and tendrils prove, that the mentioned specimens are found in an open place. I can not imagine, in what manner the pitchers have been placed when the leaves were spread horizontally. Therefore I suggest, that the plant has grown against the perpendicular wall of the G. Kelam, and that the leaves stood vertically, the pitchers behind it. It is, however, improbable, that "N. clipeata" can grow only against perpendicular walls, but it is not clear, what may be the manner of growing in other habitats."
