NOTES ON FLOWERS.

Eucalyptus macrocarpa, Hooker (large 
fruited Gum-tree). — Myrtacete § Leptosper- 
meae. — A very handsome shrub of the larger 
order, that is to say, growing several feet 
high ; at Kew, plants five years old and five 
feet high, have blossomed freely. The plant 
is everywhere covered with a glaucous white 
powdery substance, and the young branches are 
four-sided : the leaves are numerous, opposite, 
elliptic-ovate, or cordate, three to four inches 
long, the base half clasping the stem ; the 
flowers are solitary and axillary, nestled 
among the leaves; they are red, entirely with- 
out petals, the conspicuous portion being a 
large tuft, more than two inches across, of 
highly coloured threads or stamens. Native 
of Guangan, an open sandy desert in New 
Holland, where it is called Morral by the 
aborigines. Introduced in 1842 to the Botanic 
Garden, Kew. Flowers in summer. Cul- 
ture. — Requires a large greenhouse ; very 
suitable for a conservatory; loam and sandy 
peat, and plenty of pot room; propagated by 
cuttings, not too ripe, planted in sand under 
bell glasses. (270) 
Tritonia aurea, Pappe (golden Tritonia). 
— Iridaceae. — A very beautiful plant, with 
roundish bulbs, which send out offsets from 
clefts in their sides. The stem or scape, which 
is two-edged, grows from a foot and a half to 
two feet high, furnished in the lower part with 
long narrow sword-shaped leaves, arranged in 
two rows, and in the upper part becoming 
branched into a largish panicle. The flowers 
are of a very striking rich deep orange 
colour, and are produced abundantly; they 
consist of a slender tube about three-fourths 
of an inch in length, with a limb of six oblong 
segments, expanding widely, the three outer 
segments being somewhat the smallest ; from 
the centre of the flowers project the three long 
stamens, and the three-cleft style. Native of 
Caffraria, in the colony of the Cape of Good 
Hope. Introduced in 1844 by Mr. James 
Backhouse. Flowers in the latter part of 
summer. Culture. — Half-hardy, a splendid 
plant for a bed in the flower-garden, the co- 
lour being rich and rare ; turfy peat and 
sandy loam ; propagated bv offsets from the 
roots. (271) 
Dendrobidji cretaceuji, Lindley (chalk- 
white Dendrobe). — Orchidaceae § Malaxeas- 
Dendrobidaa. — A neat and distinct epiphytal 
species, with slender stems, and thin lance- 
shaped leaves, the flowers growing from the 
mature naked stems opposite where the leaves 
had been ; they are produced singly, although 
the plant is stationed in a group of the genus 
which is said to have the flowers in pairs, or 
in threes. The blossoms are remarkable for 
their dull chalky whiteness, the tip being, 
however, elegantly pencilled with crimson ; 
the sepals and petals are lance-shaped, and the 
hood-like lip is covered inside and outside with 
short close white fur. Native of India — Moul- 
mein, Mergui, and the Khasiya hills. Intro- 
duced in 1840. Flowers in July. Culture. 
— Requires a stove ; turfy peat soil ; propa- 
gated by dividing the plant. (272) 
Iris aurea, Lindley (golden Iris). — Iri- 
daceae. — A herbaceous perennial plant, having 
the habit of and some affinity to Iris ochro- 
leuca. It has sword-shaped leaves, and pro- 
duces several blossoms at the top of the stems; 
they are of a deep golden yellow colour, and 
have a showy character. Native of India 
[North ?] ; raised by Messrs. "Whitley and 
Osborn of Fulham, from Indian seeds, pre- 
sented to them by Dr. Royle. Introduced in 
1841. Flowers in July. Culture. — Hardy; 
common garden soil ; propagated by dividing 
the plants. (273) 
Vanda tricolor, Lindley (three-coloured 
Vanda). — Orchidaceas § Vandeae-Sarcan- 
thidaa. — A handsome epiphytal species, with 
long strap-shaped, distichous grooved foliage, 
and bearing lateral racemes of a few large 
handsome flowers, the sepals and petals of 
which are greenish-yellow, dotted and blotched 
with cinnamon-brown, and the lip rose- 
coloured, its lateral lobes being rounded and 
colourless. It has the habit of Vanda Rox- 
burghii, and is still nearer related to Vanda 
Hindsii, a species of New Guinea not yet in 
cultivation. Native of Java. Introduced in 
1845. Flowers in the autumn. Culture. — 
Requires a moist stove ; to be attached to a 
block of wood, or planted in an open basket, 
and suspended ; propagated by division of the 
plant. (274) 
0D0NT0GL0SSUMMAxiLLARE,i^c?Zt-?/ (maxil- 
lae-lipped Toothtongue). — Orchidaceas § Van- 
deaa-Brassidaa. — A beautiful epiphytal plant, 
which might be readily mistaken for Odont. 
Cervantesii, which it much resembles in its 
blossoms. The sepals are acutely lance-shaped, 
the petals broader, blotched with red on a 
white ground ; the base of the lip is similarly 
marked. The present plant is known by a 
very large yellow appendage, which is seated 
at the base of the lip. Supposed to be a 
native of Mexico. Introduced about 1846. 
Flowers in September. Culture. — Requires 
a cool stove ; turfy peat soil ; propagated by 
division of the plant. (275.) 
Eria convallarioides, var. major (large 
close-headed Eria). — Orchidaceae § Malaxeaa- 
Dendrobidaa. — This variety is much handsomer 
than the original species. It has a compressed 
stem, bearing at top three or four oblong 
lance-shaped leaves, beneath which are situ- 
ated the dense drooping racemes of small 
white flowers. Native of India. Introduced 
about 1844 ? Flowers in — ? Culture. — ■
