AN ENCYCLOPAEDIA 
Griffinia—continued. 
stove bulbous plants, all natives of Brazil. Upper seg- 
ments of the perianth distinctly broader than the others, 
and directed upwards; two of the remaining three spread 
out at right angles, and the third directed downwards. 
Leaves broad, usually stalked, and peculiarly netted.

Fic. 152. GRIFFINIA BLUMENAYIA, 
Griffinias thrive in well-drained fibrous loam. After 
growth is completed, water should be withheld for a 
time, in order to thoroughly ripen the bulbs. All the 
species, unless forced, flower in spring and summer.

GRINDELIA (named in honour of David H. Grindel, 
a German botanist, 1766-1836). Syn. Donia. ORD. 
Composite. A genus containing about twenty species of 
hardy or nearly hardy, biennial or perennial, shrubby or 
herbaceous plants, natives of North America and extra- 
tropical South America. Flower-heads yellow, solitary at 
the ends of the branches, and from lin. to 2in. across. 
Leaves alternate, sessile or semi-amplexicaul, often rigid, 
dentate, or ciliato-serrate. Grindelias are of easy culture 
in peat and loam. Propagated by seeds, sown in spring 
or autumn, in a cool greenhouse or frame; by cuttings ; 
and by divisions.

GRISELINIA (named in honour of Frane. Griselini, 
an Italian botanist, who flourished in the middle of the 
eighteenth century). ORD. Cornaceæ. A genus com- 
prising eight species of trees or shrubs, natives of New 
Zealand, Chili, and Brazil. Flowers dicecious, in terminal 
panicles. Leaves alternate, often unequilateral, oblong, 
sub-quadrate or lanceolate, thick, coriaceous, entire, 
spinose-dentate or angulate; ribs inconspicuous; veins 
reticulated. Griselinias thrive in light rich loam, and are 
propagated by cuttings, or by layers. The species de- 
scribed below are probably the only ones yet in cultiva- 
tion. 
G. opiate fl. as in G. lucida, l ovate or 
oblong, less oblique at the base, wedge-shaped or narrowed into 
the slender rather long petiole; veins very obscure below, A. 30ft. 
New Zealand, 1872. — Ao 4 
lucida (shining). A. minute; pedicels jointed, very short; 
Ge iela axillary, often as long as the leaves, much branched, 
i ly pubescent, with spreading golden (when dry) hairs. 
l vi liquely ovate, obovate or oblong, quite entire, obtuse or 
rounded at the tip, very unequal towards the base, one side much 
narrower than the other ; veins very distinct on the under surface, 
h, 10ft, to 12ft. New Zealand. G. macrophylla does not appear 
to be more than a large-leaved form of this.
