Rises napi). See Cabbage Caterpillars, in present 
volume. 
GREENWEED. ‘This name is also applied to 
Genista pilosa (which see). 
GREIGIA. Three species of this genus are described 
by J. G. Baker, natives of sub-temperate Chili. They 
are distinguished from Karatas by haying large lateral 
heads of flowers, basifixed anthers, and exserted, falcate, 
untwisted stigmas. Fruit a large, whitish, rather pulpy 
berry. Leaves very long. 
G. clandestina (secret). A synonym of G. sphacelata. 
GREVILLEA. To the species described on pp. 97-8, 
Vol. II., the following should be added : 
G. annulifera (annulet-bearing).* #1. sulphur-yellow, shortly 
pedicellate; perianth Jin. long; style upwards of lin. long, 
curved, very stout ; racemes 3in. to 4in. long, shortly pedunculate, 
panicled at the ends of the branches. July. /. spreading and 
recurved, 3in. to Sin. long, pinnate ; segments lin. long, distant, 
linear-subulate, rigid; petioles 4in. to lin. long. h. 6ft. to 8ft. 
Shrub, (B. M. 6687.) 
G. Hilliana (Hill’s). #. small and very numerous, in dense, 
cylindrical racemes 4in. to Sin. long. J. petiolate, either 
entire, ovate-oblong or elliptical, 6in. to 8in. long or longer, 
and deeply divided at the end into two or three lobes, or 
deeply pinnatifid with five to seven lobes, 1862, A large 
tree. (B. M. 7524.) 
G. Hookeriana (Hooker's). 7. dull yellowish, about 4in. long, 
with long, crimson styles ; racemes 2in. to 3in. long, dense, one- 
sided. /. rigid, pinnate, having three to nine pairs of linear 
segments. 1886. (B. M. 6879.) 
G. pulchella (rather pretty).* 1. white, in dense, terminal or 
axillary, usually glabrous racemes sin. to lin. long. J. pin- 
nate, lsin. to 3in. long; segments seven to eleven, cuneate, 
trifid or three-toothed. fh. lft. to 2ft. 1879. A slender, 
divaricate shrub or under-shrub. (B. M. 5979.) 
G. robusta elegantissima (very elegant).* /. broader than in 
the type. 1892. A robust and charming variety. 
G. Thelemanniana splendens (splendid). //. crimson, larger 
than in the type ; spikes short, dense, recurved. J. bipinnatitid, 
rigid; segments linear, 1883. This is apparently a form of 
G. Wilsoni, (R. H. 1882, p. 456.) 
GREWIA. To the species described on p. 98, 
Vol. II., the following should be added : 
G. orientalis (Eastern). . yellowish-white, three to a 
peduncle. July and August. JU. ovate-oblong, acuminate, 
crenulate, velvety, reddish when young. India, 1767. 
G. parviflora (small-flowered). . yellow, small, in dense, 
peduneculate umbels hidden by the leaves. 7. large, unequally 
serrated, with three prominent veins, hispidulous above, 
whitish beneath. h. 2ft. to 3ft. North China, 1888. Of more 
botanical than horticultural interest. 
Fic. 422, GREY DAGGER MOTH AND CATERPILLAR. 
GREY DAGGER MOTH (Acronycta psi). A dis- 
tinctive, very destructive, and common insect, whose 
caterpillars feed upon a large number of garden plants 
—Plums, Pears, Roses, &c. ‘The Moth (Fig. 422) is 
on the wing during May and June. It is about Idin, 
Grey Dagger Moth—continued. 
in spread of wings. The fore-wings are grey-whitish, 
thickly dotted with brown, with numerous lines, and the 
distinctive markings near the anal angle resembling the 
Greek wy, are responsible for the common name. The 
hind-wings are whitish, sprinkled with greyish. The eggs 
are deposited singly. The larye (Fig. 422) are con- 
spicuous, being of a blackish-grey, with a broad, 
yellowish dorsal stripe, broad, whitish stripe at side, 
and a lateral series of orange or reddish marks. 
Segment five bears a long, narrow, blackish prominence 
or tubercle; while segment twelve has a smaller one. 
There are numerous yellowish and blackish hair-tufts. 
The lary, although so conspicuous, are not taken by 
many birds, probably on account of their hairy nature. 
The larve are feeding during August and September. 
The pupa-state is passed in a cocoon in a crevice of the 
food-plant. 
Except in the case of fruit-trees, the caterpillars 
would be best destroyed by poisoning their food-plant 
with one of the arsenites. Plum and Pear trees at the 
time stated should be syringed with weak Kerosene 
Emulsion or a similar preparation. 
GREY GUM. See Eucalyptus resinifera. 
GRIELUM (from graios, old; in allusion to the hoary 
leaves). Orb. Rosacee. A small genns (three species) of 
greenhouse annuals, natives of South Africa. Flowers 
yellow, large, solitary, on axillary peduneles; petals 
five; stamens ten. Leaves alternate, hoary, pinnately 
decompound. G. humifusum and G. tenwifoliwm have 
been introduced, but are probably no longer in cultiva- 
tion. 
GRIFFINIA. To the species described on p. 99, 
Vol. II., the following should be added : 
G. hyacinthina micrantha (small-flowered). In this variety 
the flowers scarcely exceed lin. in length. 1880. 
G. intermedia (intermediate). ., perianth pale lilac, 1sin. to 
2in. long, the tube short, the segments oblanceolate; umbel 
six- to ten-flowered; peduncle slender, lft. long. 7. oblong, 
acute, cuneately narrowed into a long petiole. Bulb ovoid, 
longer than in G. hyacinthina. (B. R. 990.) 
G. Liboniana (Libon’s). //., perianth pale lilac, lin. to 1Jin- 
long, with scarcely any tube; umbel six- to eight-flowered ; 
peduncle two-edged, lft. long. March. J. five or six, con- 
temporary with the flowers, sessile, oblong, acute, 3in. to 4in. 
long. Bulb lin. in diameter. 1843. (L. J. F. 290.) 
G. parviflora (small-flowered). j/l., pevianth pale lilac, jin. to 
lin. long, the segments lanceolate-unguiculate; umbel ten- to 
fifteen-flowered ; peduncle nearly lft. long. February. J. three 
or four to a bulb, contemporary with the flowers, oblong, 
acute, 6in. long, narrowed to a 6in. petiole. Bulb ovoid, 2in. 
to 3in. in diameter. 1815. (B. R. 511.) 
GRINDELIA. Syn. Demetria. Flower-heads hetero- 
gamous, radiate, or rarely homogamous through the rays 
being absent; invyolucral bracts in many series; recep- 
tacle flat or convex. 
G. coronopifolia (Coronopus-leaved). A synonym of 
Xanthocephalum centauroides. 
G. grandiflora is a form of G. squarrosa. 
GRISEBACHIA. A synonym of Howea (which see). 
GRISELINIA. Syws. Decostea, Pukateria, Scopolia 
(of Forster). Flowers minute. As now constituted, 
according to the ‘‘Index Kewensis,”’ this genus comprises 
only the two species described on p. 98, Vol. IT. 
GRONOPHYLLUM (from grone, a hollow or cave, 
and phyllon, a leaf; probably referring to the shape of the 
perianth segments). Orb. Palme. A small genns (four 
species) of unarmed, stove Palms, with a slender, annulate 
trunk, natives of New Guinea and the Celebes. Spadix 
shortly peduneculate; complete spathes three, elongated, 
caducous ; bracts and bracteoles connate in a very short 
ring. Fruit small. Leaves terminal, equally pinnatisect ; 
segments cuneate, one- to three-nervyed. G. microcarpwm 
is in the Kew Collection, but is not generally cultivated. 
GROTTO. Usnally a dell in which the sides are 
lined with rockwork, tree-roots, or tree-stems, arranged 
with taste and planted with Ferns, trailing plants, and 
other subjects liking more or less shade. Such Grottoes 
always look best when a stream is trickling through them, 
or when a pond is near; and if under trees they form a 
cool and pleasant resort during the summer months.
