REFERENCE TO THE PLATE.

As an interesting desideratum, this plant has stood long amongst botanical collectors; but till the year 1801, it was never seen, in a vegetating state, in Britain; at which period, it was introduced to our gardens, by Mr. Niven, from the Cape of Hope. It is not, we believe, (although considered hitherto as such,) an annual; but rather, a half woody shrub, easily destroyed by moisture. As the seed appears to ripen freely, although there seems no other mode of perpetuating the plant, we shall stand in no danger of losing it; its attractions are, indeed, not great as to beauty, but much so as to singularity; since we have no plant to which it affines in general habit. The seeds should be sown on a gentle hot-bed, in March, and transplanted when about two inches high, into pots, to flower, which they will do about September. Our drawing was made at the Hammersmith Nursery. Having had the opportunity of examining the flowers, of more than twenty plants; we are convinced it has been wrong placed by Van Royen to decandria; for although many flowers may be found, even on the same plant, some with eight, others with ten chives, yet at least 90 out of 100 have twelve; wherefore we have, without scruple, placed it to dodecandria.
