DAVIDSONIA. 



The only species of this Australian genus (on!. 

 Saxifrageoc) is an attractive stove plant, the young- 

 leaves of which are bright red. It thrives in a 

 mixture of peat, loam, and sand, and may be 

 increased by stem endings in sand under a bell- 

 glass over bottom hi at. 



Only Species : 



pruriens, 3', Ivs. red to deep grn. (pungens is 

 a var.). 



DAVIESIA. 



A genus (urd. LeguminosEc) of evergreen shrubs 

 that grow best in the greenhouse. Propagation is 

 by cuttings of very firm wood in sandy soil beneath 

 a bell-glass ; or by seeds sown in heat when pro- 

 curable. A compost of loam and peat suits.

DEATH'S HEAD HAWK MOTH. 



In England this large, night-flying moth (Sphinx 

 atropos, or Manduca atropos) is much more common 

 than it used to be. It can never be mistaken, 

 owing to the skull-like- marking on the thorax.

 stpiarro>a, 2', Jc., yel. 



The larva: feed on the Potato, but are sometimes 

 iound on Buckthorn and other plants; a larva 

 when full grown will be >" long, yellow, marked 

 with purple. When full-fed it burrows 8" or 10" 

 below the surface soil and turns into a reddish 

 brown pupa ; in this state it is often exposed 

 during winter digging, and should then be killed. 

 The moth appear.-, in spring or early summer, and is 

 one of the few species having power to emit a sound. 



DECABELONE. 



A genus (urtl. Asclepiadeie) of succulent plants 

 that thrive in the greenhouse in a mixture of loam 

 and brick rubbish, with frequent applications of 

 liquid manure when in active growth. Propaga- 

 tion is by cuttings, the base being dried before 

 insertion in sand. 



Principal Species : 



Barklyi, ti", yel., spotted red. 



DAVALLIA I'AUVILA. 



DECAISNEA. 



The best known species of this genus (ard. 

 Berberideso) is an upright Himalayan shrub that 

 should be accommodated in the greenhouse. 

 Propagation is by seeds, when procurable, and 

 by cuttings. Soil, mellow loam with sharp sand. 



Only Cultivated Species : 

 insignis, 8', My., yel- Fargesii, clo?o to insignis. 



lowish. 



DECUMARIA. 



Pretty twining plants (iirrf. Saxifrage:*'), propa- 

 gated by cuttings in summer under a shaded 

 hand-light. They grow in dry. rich soil in a warm 

 position where they have a trellis or bush to t wine 

 over. There are several forms of the undcrnamed.
