to the welfare of the latter, or do equally well without, as 
the case may be. They should be potted in a compost of 
three parts peat and one of silver-sand, with a little 
chopped sphagnum added. 
The drainage, especially 
when they are grown in ® 
ay 
pots, must be good, and none 
of them like exposure to the 
fall rays of the sun. Pro- 
pagated by means of spores, 
or by the division of the 
crowns in early spring. 
To those described on p. 
486, Vol. I., the following 
varieties should be added: 
D. aspera multifida (many- 
cleft). fronds arched, several 
times forked at the apex; 
when young, claret-coloured. 
peat evergreen. See Fig. 
D. caudata Harryana 
(Harry Veitch’s).* This differs 
from the type in being stouter, 
of firmer texture, and larger. 
1884. Garden variety. 
D. Kunthiana is now re- 
garded as a good species, and 
not as a variety of D. media. 
D. media Brackenridgei 
(Brackenridge's). fronds tirm ; 
pinne rather obtuse, fewer 
and more distant than in the 
type. sori dense, irregularly 
disposed in two rows. Fiji. 
D. m. connexa (connected). 
fronds lavger than in the 
type; pinne sometimes 3in. 
or more in length, much softer 
and of a more papery tex- 
ture. 
D. m. Milnei (Milne’s). sti. 
black, jronds firm, parchment- 
like, dark green; _pinne 4 
sharply toothed, closely set, FIG. 548. FERTILE AND BARREN 
the central ones often 4in. to FRONDS OF DoopIA MEDIA. 
Sin. long. sori in two rows. 
Kermadec Islands. 
D. m. Moorei (Moore's). sti. black. fronds flexible or pendu- 
lous; pinn very acuminate, sharply toothed, the central ones 
Zin. long. sori in one row. New South Wales. 
DOR BEETLE. See Shard-borne Beetle. 
DORCUS PARALLELOPIPEDUS. See Lucanus 
cervus.

see). 
DORITIS (from doru, a lance; the labelluam in some 
species is lance-shaped). Orp. Orchidew. A genus em- 
bracing five species of stove or greenhouse Orchids, natives 
of India and Malaya. They have the characters of Phale- 
nopsis, but the column is narrowly winged, and its foot 
forms a conical mentum with the lateral sepals. Two 
species have been introduced. For culture, see Phale- 
nopsis. 
D. teenialis (band-like). /. mauve-purple, Zin. in diameter ; mid- 
lobe of lip dark red or purple, the side lobes very narrow, 
spathulate, the tips of the forked appendage hooked ; scape lin. 
to 2in, long, few-flowered. 7. few, in. to 5in. long. Roots lft. to 
3ft. long, din. to 4in. broad, forming large, tortuous tufts. Sub- 
tropical Himalayas. 
D. Wightii (Wight’s). /1., mid lobe of lip obcordate, the side 
lobes broad, cuneate-obovate; scape much longer. J. rather 
larger. Otherwise like D. tenialis, Eastern Himalaya. 
DORMANT BUD. A bud which remains, perhaps 
for years, undeveloped. 
DORONICUM. These plants are well suited for 
naturalising in dry situations, where few other subjects 
would flourish. ‘To the information giyen on pp. 486-7, 
Vol. I., the following should be added: 
D. Bourgeei. A synonym of Senecio multiflorus. 
Vol. V. 
Included under Othonna (which 
Doronicum—continued. 
D. Clusii (Clusius’). A synonym of Arnica Clusii. 
D. cruentum (bloody). The correct name of Cineraria cruenta. 
D. montanum (mountain). A synonym of Arnica montana. 
D. plantagineum excelsum. This is the plant known in 
gardens as the Harpur Crewe variety. 
DORSTENIA. Syns. Kosaria, Sychinium. Abont 
forty-five species, all American and African except one 
(Indian), are included in this genus. Flowers monecions, 
crowded on a flat, simple or lobed, androgynous receptacle. 
Leaves alternate or radical, entire or lobed. To the species 
described on p. 487, Vol. I., the following should be added : 
D. Walleri (Waller's). _7., inflorescence green, star-shaped, 
nearly lin. across, with five tails 2in. long. ¢. ovate, fleshy, 2in. 
to 5in. long. Nyassaland, 1893. A new species, allied to 
D. Mannii. 
DORYANTHES. To the species described on pp. 487-8, 
Vol. I., the following should be added: 
D. Guilfoylei (Guilfoyle’s). /l. crimson, Amaryllis-like, numerous, 
clustered, borne on a spike 16ft. high. 7. 9ft. long, 8in. wide. 
Queensland, 1893. According to Mr. J. G. Baker, this is merely 
a form of D, Palmeri. (Gn., 1893, xliv., p. 69.) 
DORYDIUM. A synonym of Asphodeline (which 
see). 
DORYOPTERIS NOBILIS. A 
Pteris elegans (which see). 
DORYPHORA (from dory, a spear, and _ phoros, 
bearing ; in allusion to the spear-like appendages to the 
anthers). Syn. Learosa. OrbD. Monimiacer. A monotypic 
genus. The species is a rare, highly aromatic, warm green- 
house shrub or tree, of considerable size but of irregular 
growth, glabrous except the inflorescence, or the young 
shoots hoary-tomentose, the whole plant highly aromatic. 
It is closely allied to Atherosperma (which see for 
culture). 
D. Sassafras (Sassafras). fl. about 4in. long, hermaphrodite, 
three together on short, aaa peduncles ; perianth segments 
six, in tworows; connective of the anthers produced into a long, 
linear-subulate appendage. J. petiolate, ovate, elliptic, or 
oblong-lanceolate, acuminate, narrowed at base, 2in. to 4in. long, 
coarsely toothed, penniveined and reticulated beneath. New 
South Wales, 1895. 
DORYPHORA DECEMLINEATA, or COLO- 
RADO BEETLE. See Potato Insect Pests. 
DOT MOTH (Mamestra persicarix). An insect allied 
to the Cabbage Moth (Mamestra brassice), quite as 
common, and a far more general feeder. In fact, there 
are very few plants found im gardens generally which 
come amiss to the caterpillars of the Dot Moth. We 
have found them upon Ferns (Pteris), Ivy, Chrysanthe- 
mums, Lettuce, Pelargoniums, Gooseberries, and many 
others. Being of such omnivorous tastes their presence is 
very unwelcome in gardens. 
The Moth is on the wing in June and July, and is 
nocturnal. In stretch of wings it measures from Isin. to 
13in. The fore-wings are dark purplish-brown, approaching 
black, with numerous small ochreous spots and two blackish- 
centred kidney-shaped dots (hence the common name). ‘The 
larve vary from dirty green to brown, and have a whitish 
line on the back,- with oblique dark marks on segments five, 
six, and twelve, and lighter spots on the other segments. 
They are whitish in the vicinity of the spiracles. They 
feed in August and September, and then pupate in the 
earth. 
When troublesome upon Gooseberry and other fruit 
bushes they may be ousted with Paris Green, as they 
appear after the fruits haye been gathered. Where flower- 
ing plants are concerned, they should be hand-picked at 
night by the aid of a lantern when they are feeding. 
When at rest they are too well protected to be readily 
seen by either man or birds. 
DOUBLE TONGUE. ‘See Ruscus Hypophyllum. 
DOUCIN STOCKS. The Paradise Stock is known as 
the Donecin, and is largely employed for cordon, bush, or 
other dwarf form of Apple trees in which the growth is 
restricted. The French Doucin, or Paradise Stock, is only 
suitable for pot or other small-growing trees. The English 
Doncin is a more vigorous, durable, and productive variety, 
and is superior to the French in every way. The Doucin is 
both budded and grafted with the Apple, the former mode
