Cult. The species of Pharnaceum are scarcely worth culti- 

 vating, except in botanical gardens, being for the most part 

 weedy-looking plants. The greenhouse shrubby kinds thrive 

 well in a mixture of sandy loam and peat, but the pots should be 

 well drained with potsherds. Cuttings planted under a hand- 

 glass in the same kind of soil will root freely, but they may be 

 increased more easily by seed, which often ripen in abundance. 

 The annual species should be sown in pots in the spring, and 

 placed in a moderate hot-bed, where they may remain until they 

 ripen their seed, or they may be removed into the greenhouse in 

 June.

Madagascar Physa. PI. trailing. 



Cult. This plant should be sown in a pot in a mixture of 

 sand, loam, and peat, and placed in a hot-bed, where it may 

 remain until it ripens its seed. Not worth cultivating. 



XXVI. HOLO'STEUM (from oXoe, holos, all ; and oartov,

 is no bone, being soft and delicate. This species of wit is not un- 

 common, even at the present day, but applied to men not plants).
