glass, in heat. 
XXII. GYROSTE' MON (from yvpoc, gyros, a circle, ernpwy, 
stemon, a stamen; in allusion to the stamens being twisted round 
each other in a circular manner). Desf. mem. mus. 6. p. 16.

place called Baye des chiens marins. Flowers in racemes. 
Cotinus-leaved Gyrostemon. Shrub 6 feet. 
Cult. These shrubs will thrive well in a mixture of loam, 
peat and sand; and ripened cuttings will root in sand, under a 
hand-glass. 
XXIII. CHRISTIA'NA (in memory of Christian Smith or 
Schmidt, M. D., a young Norwegian botanist of great promise, 
who went out with Captain Tuckey in his unfortunate expedi-

African Christiana. Shrub. 
Cult. If ever this shrub should be introduced into Europe, 
we would recommend its being grown in a mixture of loam, peat 
and sand ; and ripened cuttings will probably root in sand, under 
a hand-glass, in heat.
