PROTEACE.E Juss. 
Essential Character. — Calyx four-cleft, witL a valvate aestivation. Stamens four, sometimes in part sterile, opposite the segments of the calyx. 
Ovary consisting of a single carpel, superior. Style simple. Stigma undivided. Fruit dehiscent or indehisceut. Seed without albumen. 
Description, &c. — The genus from which this order takes its name consists of plants which are more curious 
than beautiful ; but in some of the other genera belonging to the order the plants are very ornamental. In all, 
however, there is a certain singularity of form which distinguishes them from every other order. Most of these 
plants are natives of Australia, particularly those belonging to the genera Banksia and Dryandra, which were 
discovered by Sir Joseph Banks and named after him and Dr. Dryander who accompanied him. The flowers of 
these plants, though very cm'ious, can scarcely be called ornamental, and, in fact, the only genus containing 
ornamental greenhouse plants is Grevillea. 
GENUS I. 
GREVILLEA R. Br. THE GREVILLEA. 
Un. Syst. TETRANDRIA MONOGYNIA. 
Generic Character. — Corolla irregular ; petals secund, the apices concave, staminiferous. Anthers inclosed. Hypogynous gland single, 
dimidiate. Stigma oblique, depressed. Follicles one-celled, tivo-seeded ; seeds having a margin or a short wing at the apex. 
Description, &c. — The botanical construction of these plants is very curious, and the great length of the style 
with its depressed stigma is so very peculiar that no one who has once observed the flower of a Grevillea can ever 
be in any doubt respecting any other species of the genus. The name of Grevillea was given in honom’ of the 
Right Honourable Charles Francis Greville.

Description, &c. — This is a very beautiful species, 
colours. It is a native of New Holland, whence it was 
THE CRIMSON GREVILLEA. 
Specific Character. — Leaves elliptic-oblong, somewhat attenuated 
at the base, reflexed at the margin. Racemes of flowers branched; flowers 
downy inside. Calyx clothed internally with a long white beard. 
Pistil smooth. 
nearly allied to G. sericea, but much more brilliant in its 
introduced in 1829. 
OTHER SPECIES OF GREVILLEA. 
G. SERICEA R. Brown. 
This species was introduced in 1790, and consequently was one of the first known in this country. It is a 
hardy greenhouse plant, flowering nearly all the year. 
G. BUXIFOLIA R. Brown. 
This is a very curious species of the genus, and is remarkable for having the appearance of a box-tree when not 
in flower. It was introduced at the same time as G. sericea, but being less ornamental in its flowers, it is now 
very seldom seen.
