GREGORIA VITALIANA. A synonym of Andro- 
sace Vitaliana (which see). 
GREIGIA (named in honour of Major-General Greig, 
a promoter of Russian horticulture). ORD. Bromeliacee. 
A genus comprising two species of large-growing herbs, 
producing a fine crown of Pineapple-like spiny leaves. 
Greigias are usually described as requiring -stove heat, 
but in summer they may be placed outside the rock garden 
or warm border, in light, perfectly-drained soil. In the 
—— they require treatment similar to Billbergia (which 
see).

G. sphacelata (scorched). rose-coloured, sessile, overlapping 
each other, and dis; in dense heads ; bracts ory tinged with 
en. Summer. l. numerous, erect, sword-sha acuminated, 
ringed with stiff spines. h. 3ft. Chili, 1865, See Fig. 150.

GRENVILLEA. Included under Pelargonium 
(which see). 
GREVILLEA (named in honour of C. F. Greville, a 
patron of botany). Including Anadenia, Lysanthe, Man- 
glesia, Molloya, Strangea, Stylurus. Orv. Proteacee. A 
large genus (more than 160 species have been described) 
of beantiful greenhouse shrubs or trees, limited, with the 
exception of seven New Caledonian species, to Australia. 
Flowers in pairs along the rachis of a short and umbel- 
like or elongated raceme, rarely reduced to a single pair ; 
racemes either terminal or also axillary, rarely all axillary. 
Grevilleas thrive with ordinary greenhouse treatment. 
They should be repotted after the flowering season. For 
general culture and propagation, see Cytisus. 
G. acanthifolia (Acanthus-leaved).* fl. reddish, densely disposed 
in racemes 3in. or 4in. long; styles (as in the other species) long, 
filiform, considerably exceeding the perianth in length. June.
