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


(204) Conostylis bracteata; foliis glabris marglne densè setulosis scapo furfuraceo mono-di-phyllo æqualibus, capitulis bracteâ foliaceâ canescente brevioribus, perianthiis intus glabris extus aspero-villosis, antheris subsessilibus uniseriatis.—Villi calycis breves rigidi ad apicem usque setoso-plumosi.

(205) Conostylis dealbata; foliis incanis ciliatis scapo tomentoso multò brevioribus, racemis capitatis bifidis subsecundis bracteâ obtusa longioribus, perianthiis intus glabris extus aspero-tomentosis, antheris subsessilibus uniseriatis.—An C. candicans, Endl.? sed perianth, intus glabrum.

(206) Conostylis caricina; foliis linearibus rigidis integerrimis glaberrimis falcatis scapo simplici tomentoso medio monophyllo duplò longioribus, capitulis bracteis longioribus, perianthiis intus glabris extus aspero-tomentosis: laciniis tubo duplo longioribus, staminibus uniseriatis.

(207) Conostylis æmula; foliis rectis acuminatis glabris setis longissimis inflexis ciliatis scapo simplici lanato medio monophyllo longioribus, perianthiis intus lanatis extùs aspero-villosis: laciniis tubo brevioribus, staminibus biseriatis.—Variat. folio scapi herbaceo elongato setoso et membranaceo glabro; an sp. 2?

(208) Blancoa. Perianthium extus tomentosum, ferè inferum, elongato-campanulatum: limbo 6-dentato erecto æquali, tubo inter lacinias plicato. Antheræ 6, subsessiles, basi laciniarum insertæ. Capsula nucamentacea, ferè libera, nitida; fundo perianthii persistentis inclusa, 3-valvis; valvis medio septiferis seminiferis stylis apice tantum cohærentibus terminatis.

Blancoa canescens. Acaulis, Barbaceniæ vultu. Folia equitantia, incana, retrorsum falcata, acuminata, scapi longitudine. Scapus palmaris, furfuraceo-tomentosus, pone basin monophyllus, supra medium squamâ unicâ cucullatâ rigidâ uniflorâ instructus, apice bi-triflorus. Flores magni, nutantes, extus pedunculique plumoso-villosi.
