Trees. 23 



P. longifolia. A resin-yielding pine of the Hima- 

 layas. It is a graceful species, with long needle-like 

 leaves. Large trees are not often met with, but seeds 

 received from Saharanpur, India, grew freely in the 

 open ground at Alexandria. 



P. pinaster The Maritime pine and P. pinea 



The Stone pine which has edible seeds, are common in 

 the country. 



P. elata. A dwarf species, only rising a few feet' 

 high ; is sometimes used in Alexandria for the centre 

 of large flower-beds. 



Euphorbia pulcherrima Poinsettia Bint-el-soul. 

 A familiar object in Egyptian gardens. Its crimson 

 bracteal leaves, forming large star-like heads, makes 

 it conspicuous at Christmas time. The plant strikes 

 freely from cuttings, and blooms on the new 

 wood. It should be cut back to a bud or two from 

 the stem after flowering, and should be planted in a 

 sheltered position, so that its beauty is not destroyed 

 by the wind. Specimens trained in standard form have 

 also a good effect. 



E. pulcherrima, var. albida. A white variety is 

 sometimes grown, but is of comparatively little beauty. 



E. neriifolia and E. tirucalli are also suitable for a 

 shrubbery and grow into fine specimens. 



E. jacquiniflora is a shrub rather than a tree, bearing 

 a profusion of vermilion flowers, and slender thorny 

 stems. It is a pretty plant for a dry sunny spot, or 

 as a pot plant. 



Erythrina crista-galli The Lobster Plant. A 

 showy deciduous tree, with ternate leaves and clusters 

 of claw-like flowers, of a deep crimson colour grow- 

 ing on the young wood. These flowers continue in 

 bloom throughout the spring and summer. All the 

 previous year's growth requires pruning back to the 

 old wood, which should be done in January.
