Grevillea (Named in honour of C F)

(named in honour of C. F. Greville, a patron of botany). Including Anadenia, Lysanthe, Man glesia, Molloya, Strangea, Stylurus. ORD. Proteaceae. A large genus (more than 160 species have been described) of beautiful 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. l. rigid, divided nearly to the centre; lower divisions coarsely toothed; very suggestive of Acanthus foliage. h. 4ft. 1824. (B. M. 2807.) G. alpestris (rock). A synonym of G. alpina.

G. alpina (alpine).* fl. red, yellow; racemes very short, terminal, sessile; pedicels pubescent. May. l. rather crowded, sessile or nearly so, oval, oblong-lanceolate or almost linear, obtuse or with a small point, sometimes attaining 1in., hirsute or rarely scabrous only above, silky-villous beneath; margins revolute. h. 4ft.
