which is at all beautiful when in flower; the prickly and singularly formed leaves of some of them, especially of H. cristata, glabella, undulata, and triformis175 give them a neat but strange appearance.
Few of the Grevilleas, of which there are many species, are of much beauty; G. Thielemanniana, lately introduced by Baron Hugel, is however a magnificent plant, with large clusters of rich crimson flowers; G. bipinnatifida and quercifolia are striking species; G. brachyantha,180 a plant related to the last-mentioned species, seems to have purple flowers; and G. eriostachya,181 nearly allied to G. concinna, with spikes from five to six inches long, and yellowish linear leaves, is an object of considerable beauty.
Of Adenanthos, whose only beauty is in the leaves, which almost hide the flowers, A. sericea and A. barbigera182 are met with in the Colony. In the latter, and also in A.
