In 1748 the sixth edition of Systema Naturæ appeared, where the essential characters of Protea and Leucadendron first occur, both of them evidently derived from the natural characters previously given.

In 1753 the Species Plantarum, the most accurate of all his works, was given to the world; both genera are found in it, their species characterized, and trivial names for the first time applied to them: of Protea there are only two species, P. argentea and fusca; to the former however he referred as varieties P. saligna, conifera, and three others; to the whole adding the following observation, which may be supposed to contain his chief reason for applying his name Protea to this genus rather than to that for which in his Classes Plantarum he had first intended it. "Planta naturalis in patria argentea excellit fronde inter arbores nitidissima omnium; at culta et captiva extra patriam exuit decus; variat dein etiam domi mille modis verè Protea."

At this time he had in his Herbarium a specimen without fructification of Protea argentea properly so called; but of its supposed varieties or of P. fusca none whatever. Of his genus Leucadendron he had only one species, L. proteoides, afterwards called Protea purpurea, a plant differing in many respects from the tribe to which he had, though not without hesitation, referred it.

In 1754 the fifth edition of Genera Plantarum appeared, in which the characters of both genera remain exactly as in the second.

In 1759 was publishd the tenth edition of Systema Naturæ,
