Op this species of Crassula we know of no other figure extant, but a very small uncoloured one in the 

 Hortus Elthamensis of Dillenius. Our specimen was taken from the hot stove of the Countess de 

 Vandes, where it flowered for the first time in this country in I8O9 — in size and grandeur like the 

 C. obliqua, with an equal profusion of blossoms, and bending down as if the weight of the terminal 

 mass of flowers was too much for the stem to support j which we do not consider as the positive cha- 

 racter of it, but only arising from the situation in which it stood ; being too near the glass, which most 

 likely drew too much of its strength out in length of stalk, and in all probability occasioned the loss of 

 the plant, as it damped off very soon after flowering.
