409 
tive of Mexico, growing in lakes and ditches. 
Introduced in 1847. Flowers throughout the 
summer. The rhizomes are eaten, and bear 
the name of Cabeza di negro. Culture. — 
Requires a greenhouse ; the rootstocks potted 
in loamy soil, and set into a cistern of water 
at a moderate depth ; propagated by means of 
offsets produced on runners from the old rhi- 
zomes, and by seeds. (196) 
Ophrys tabanifera, Willdenow (gad-fly 
Ophrys). — Orchidacea? § Ophreas-Serapiadas. — 
A tuberous rooted herbaceous perennial, with 
sword-shaped leaves springing from the root, 
and an erect stem six or eight inches high, 
bearing two or three blossoms somewhat 
resembling those of our native bee-orchis. It 
was found in low swampy ground " near Cla- 
rentia," as is one of the South European 
orchids obtained by the late Dr. Herbert. 
Introduced originally in 1826, and again 
about 1846. Flowers in May. Culture. — 
Hardy ; loamy soil ; propagated very slowly 
by offsets. (197) 
Dryandra carduacea, var. angustifolia 
(narrow-leaved thistle-like Dryandra). — 
Proteaceas § Folliculares-Banksidaa. — An 
erect much-branched shrub, with scattered, 
rather distant, linear-lanceolate, rigid, sinuate- 
dentate leaves, the teeth tipped by a sharp 
spine ; the upper side is dark green, the under 
side clothed with compact white down. The 
flower heads, which resemble thistle heads, 
but are yellow, terminate the short branches, 
and are as it were surrounded by a rosule of 
leaves. A native of the Swan River colony 
of New South Wales. Introduced about 
1845. Flowers in the spring months. Cul- 
ture. — Requires a greenhouse ; free turfy 
loam ; propagated by imported seeds, or 
slowly by cuttings planted in sand, and placed 
in a hotbed. (198) 
Salvia leucantha, Cavanilles (white- 
flowered Sage). — Lamiacese § Monardeas-Sal-

growing about two feet high, w T ith four angled 
branches, woolly when young, and bearing 
narrow oblong-lanceshaped opposite leaves, 
which on the under side are furnished with 
white woolly down. The flowers grow in 
whorl-like patches, forming an elongated 
spike-like raceme, the rachis of which is 
clothed with violet coloured wool ; the calyx 
is clothed with a rich violet or lavender co- 
loured wool ; and the corolla, also woolly, is 
pure white, forming an elegant contrast with 
the calyx. A native of Mexico. Introduced 
originally to our garden? in 1825, and subse- 
quently from Nice by Lady Smirke, about 
1846. Flowers in June and July. Culture. — 
Half-hardy, or requiring a greenhouse ; loamy 
soil ; propagated by cuttings. (199)

Maxillaria). — Orchidaceas § Vandese-Maxilla- 
ridas. — An epiphytal plant, with oval com- 
pressed blackish pseudo-bulbs, oblong strap- 
shaped leaves an inch and a half broad, and 
scapes about four inches long, bearing the 
flowers, which are rather large, and have deep 
blood-red petals and a purple lip. A native of 
the forests of Merida, at the height of 6,000

Flowers in (? June). Culture. — Requires a 
stove ; turfy peat soil ; propagated by division 
of the plant. (200) 
Bee aria ledifolia,- Humboldt, $>'c. (ledum 
leaved Befaria). — Ericaceae § Rhododendrea?. 
— A handsome shrub, growing three or four 
feet high, and much branched, with oblong 
somewhat mucronate leaves, revolute on the 
margins, glaucous beneath, and beset with 
glandular hairs on both sides along the middle 
nerve ; the flowers are purple, and grow in 
handsome terminal clusters. The peduncles, 
pedicels, branchlets, and calyx, are clothed 
with viscous glandular hairs. A native of 
South America, on the top of Lela de Ca- 
raccas. Introduced in 1847, by Mr. Linden. 
Flowers in June. It is also called Bejaria. 
Culture. — Requires a greenhouse ; sandy peat 
soil ; propagated by half-ripened cuttings in 
sand in a moderate heat, or grafted in the 
same way as Indian azaleas on the Rhodo- 
dendron ponticum. (201) 
Leucothoe pulchra, De Candolle (ele- 
gant Leucothoe). — Ericaceaa § Ericeae. — A 
handsome shrubby plant, growing two feet or

w r ith the origin of which we are unacquainted. 
Raised about 1846. Culture. — Requires a 
warm frame in spring, and greenhouse in 
summer ; loam and leaf-mould ; propagated by 
cuttings of the plant, root or leaves. (203)
