- Davilioni, Baker, n. sp. This new species, intermediate 
tts veen 7° rat ‘and pol yacantha, ah G saw for the first time in the 
Jardin ď’Acclimatation at Hyères. Itis — scent, with a Sevri of 
about 30 rigid enaitori leaves, which par a length of 3—4 and a 
breath of 4} inches at the middle. They ar moderately cic when 
mature, tinged with red when young, bide concave on the face towards
