of these on each petiole. Dr. Lindley further observes that there are several different plants in the country, 
each bearing the name of Tacsonia mollissima, but which evidently do not belong to that species, as some of 
them have only two or three glands on the petioles. It is possible that this may be the reason that opinions 
differ so much as to the beauty of the flowers of 7. mollissima, as those plants which produce the most beautiful 
flowers, may probably belong to some other species.

Description, &c.—The plants belonging to this order have all fleshy stems and leaves, and generally 
ornamental flowers produced in clustered heads or cymes. ‘‘'The species,” says Mr. Don, ‘“‘are found in the dry 
situations where not a blade of grass nor a particle of moss can grow, on naked rocks, old walls, sandy hot plains, 
alternately exposed to the heayiest dews of night, and the fiercest rays of the noon-day sun. Soil is to them a 
something to keep them stationary, rather than a source of nutriment, which in these plants is conveyed by 
myriads of mouths invisible to the naked eye, but covering all their surface, to the juicy beds of cellular tissue 
which lie beneath them.” ‘The order includes numerous genera, some of which contain only small insignificant 
plants, while others have flowers of great magnitude and remarkable beauty

Generic Cuaracter.—Calyx five-parted. Petals five, distinct. Stamens five; filaments subulate. Scales five. Carpels five, 
many-seeded. (@. Don.) 
Description, &c.—The species are fleshy shrubs or herbaceous plants, generally natives of the Cape of Good 
Hope. The genus was formerly very extensive; but it has been circumscribed by modern botanists, who have 
divided the old genus Crassula into five or six modern ones. The word Crassula is derived from crassus, thick, 
in reference to the fleshy leaves.
