like chestnuts). Moreton Bay Chestnut. ORD. Leguminose.

CASTILLEJA (named in honour of D. Castillejo, a 
botanist of Cadiz) ORD. Scrophularineæ. Herbaceous, 
rarely suffruticose plants. Flowers axillary, solitary or 
terminal, and spicate ; corolla tubular, compressed, bi- 
labiate. Leaves alternate, entire, trifid or multifid; bracts 
large and coloured. These are very ornamental plants, 
With one or two exceptions, are rarely seen in cul- 
tivation. All are probably more or less parasitic in habit, 
and this accounts for the difficulty generally experienced 
in preventing the plants from being altogether lost, All 
‘succeed in a peat soil, with a little leaf mould and sand, 
but some do better in good loam. Hardy and half hardy 
pecies may be increased by seeds.

Male flowers in cylindrical spikes; perianth of 
one or two concave or hood-shaped segments. 
See Ricinus 
Female flowers in globose or ovoid spikes or 
cones; perianth none. They thrive well in a 
compost of loam and peat, with a portion of 
sand. The stronger growing species do well in 
loam. Propagated by cuttings, made of half- 
ripened shoots, in April, and placed in sand, 
under a bell glass; or by seeds.
