but flowers of a bright golden yellow. C. bracteata²⁰⁴ has smaller heads, subtended by a leafy bract, and they are covered with a coarse, rigid wool; it is very near another plant which answers to Brown's definition of C. aculeata, from which it differs in the margins of the leaves being closely serrulated, in its stem not being furnished with short smooth shining scales, and in its smaller flowers subtended by a leafy bract. C. dealbata²⁰⁵ is much like the two latter, but its flowers are almost gyrate rather than capitate, and the leaves are hoary. The remainder consist of C. setigera, R. Br., and C. caricina,²⁰⁶ both small inconspicuous species, with C. æmula,²⁰⁷ which forms sedgy tufts of leaves overtopping the yellow hairy heads of flowers.

Nearly allied to Conostylis are two genera hitherto un- described. The first, which may be called Blancoa,²⁰⁸ has a large tubular perianth with an erect limb, and plaits between the segments, included subsessile anthers, and a bony three-valved capsule which is nearly superior, and bears the placentæ on the dissepiments; this is a fine showy plant, with
