 PROSTANTHERA, Labillardien. From prosthekc, 

 appendage, and anthera, an anther. Linn. 

 14, Or. 1, Nat. Or. Lamiacece. Pretty green- 

 house plants, requiring a sandy peat soil, and 

 the pots carefully drained, as the plants are 

 apt to damp off ; they may bo increased by 

 cuttings of the young shoots, in sand, under a 



PROSTHEMIUM, Kunze. Derived from prostJiema, 

 an addition. Linn. 24, Or. 8, Nat. Or. Uredi- 

 nacece. A very minute black fungus, found in 

 autumn on the trunks of trees — betuRnwn. 



Pr6tea, Linn. From Proteus, a self-transform- 

 ing sea-god ; in allusion to the diversity of 

 appearance of the species. Linn. 4, Or. 1, 

 Nat. Or. ProUaccce. This is an extensive 

 genus of magnificent evergreen shrubs, gene- 

 rally considered difficult of culture ; but this 

 supposed difficulty may be removed by attend- 

 ing strictly to the watering of the plants. 

 The soil best suited for them is light turfy 

 loam, mixed with about a third part fine sand ; 

 the pots must be well drained, and it is ad- 

 visable to mix some small pieces of broken 

 free-stone with the soil, in potting, to prevent 

 them from retaining too much moisture ; the 

 roots are also fond of running among the free- 

 stone or broken potsherds. Care must also be 

 taken not to let them 'droop for want of water, 

 as the young roots are of a fleshy substance, 

 and are as liable to suffer from too much 

 drought as they are from too much water, 

 whenco the necessity of the waterings being 

 regular and moderate. Eipened cuttings will 

 root when taken off at a joint, planted thinly 

 in sand, and placed under a glass, but not in 

 heat ; the glass should occasionally be removed 

 to allow them to dry, as they are liable to 

 damp off. Water them, but not over the 

 leaves, whenever they want it, and let them 

 get a little dry before the glass is placed over 

 them again. Synonymes: 1, P. longifdlia; 2, 

 P. specidsa. See Isopdgon, Leucadindron, Leu- 

 cospdrmum, MimUes, Nivinia, Pelr6phila, and
