tlie middlo. These excresenoes then are very curious; 
110 other pine has such warty appearances on their 
cones. In the northern counties this curious species 
^ rcipiircs protection. 
I Pinos Avaoauuite (Ayacaliuito Pino).—A native of 
i Mexico, and a very reinarkahlo Pine. The fine loaves, 
in a cluster, are produced on little swelliiij's, or lumps, 
1 as it were, whicli give a singular and curious appoiir- 
j auce to tho tree. It has very long, slender, tapering 
1 cones, often a foot long. A collection of lir cones, 
j arranged in their several genera, would be very intercst- 
i lug and instructive; and a great number may be scon 
' in the excellent museum in the gardens at Kew ; but, if 
i my memory serves me right, they are not arranged in 
I their tribes, probably because tho gardens do not possess 
j a full series of them. 
PiNus Cembra (Cemhran Pino).—This is a beautiful 
1‘luropeau sjiecies, growing wild on the mountains of 
i Switzerland and Siberia. Tho wood is of a fine grain, 
and so soft as to bo easily carved; hence the shepherds 
of the Tyrol, and neighbouring districts, amuse them¬ 
selves by carving out of it those curious little figures of 
men and animals so well known over all Europe. The 
inhabitants extract a fine oil from the seeds, and even 
use the shells of the seeds to dye a fine brown colour. 
'I'ho trees are quite hardy enough to bear the cold on our 
highest hills. The roots are very fibrous, and, in conse¬ 
quence, it has been proved that this Pino may bo moved 
when largo with more certainty of success than any other. 
There is a variety from Siberia, but it is of slower 
growth even than the species which is not a fast-grower 
compared with other Pines. There is also a curious 
dwarf-growing variety, which Mr. Loudon names 
and a pigmy indeed it is, forming a bttlo bush from two 
to three feet high. Tho Cemhran Pine being so hardy, 
and plants of it so cheap, and producing nuts that yield 
a beautiful oil, it deserves the particular attention of 
gentlemen possessing land situated on lofty hills, or 
even mountains. 
PiNus Devoniana (Duke of Devonshire’s Pino). — In 
its native country (Mexico) this forms a largo handsome 
tree. Unfortunately, it will not boar the rigour of 
even our ordinary winters, but is well worthy of a ]ilaco 
in a lofty conservatory. Tho Mexicans call it the White, 
or Royal Pine, the wmod being almost pure white. 
PiNus nxcEi.sA (Lofty Pine).—In its native country 
this is a noble tree, attaining tho height of 120 feet. It 
grows on the mountains of llbotan, a district of tho 
gigantic Himalayas, in India. The natives call it “ The 
King of Pines,” and, from the reports of travellers, it is 
deserving that appellation. Tho branches droop so 
much that it has also boon named “Tho Weeping Pir.” 
Tho timber is of the best quality, and it yields an im¬ 
mense quantity of turpentine. It is, however, so scarce 
in the nurseries, that until tho fact of its being hardy 
is ]iroved, and seeds itrqiortcd more largely, its culture 
on a largo scale cannot bo attempted. 
PiNus riLiroLiA (Thread-leaved Pine).—The leaves of 
this curious species arc, as the name imports, long and 
slender, and it forms a handsome tree. Being a native 
of Guatemala, it is believed to bo too tender for tho open 
air of this country. This fact, however, remains to bo 
proved. 
PiNus GoRnoNiANA (Mr. Gordon’s Pine).—So named 
by iVlr. Hartweg, its discoverer, in honour of Mr. George 
Gordon, a zealous cultivator of tho tribe in tho Horti¬ 
cultural Gardens at Chiswick, whore tho finest specimen 
of this noble tree may be seen, with leaves fully 16 
inches long. The cones are large, and hang downwards, 
and are remarkable from the fact that they are non-re- 
sinous. This is one of tho tribe that ought to bo in 
every collection, however select. Though a native of 
Mexico, it is found to be hardy in tho neighbourhood of 
London. 
PxNus Grenvileeje (Lady Grenville's Pine).—A noble, 
robust species, from tho same locality as the preceding, 
and named by Mr. Gordon in honour of Lady Grenville, 
the owner of tho well-known and richest collection of 
tho tribe probably in tho world, at Dropmore, throe 
miles from tho Maidenhead Station, on tho Great 
Western Railway. 1 need not say the place is well 
worthy of a visit by every lover of rare and fine Coniferae. 
Tho species has long largo leaves, and very remarkable 
cones, which are frequently 10 inches long, tapering to 
a point. This is, like F. Gordoniana, a species that 
should bo planted in every collection in the kingdom. 
PiNus Hartwegii (Mr. Hartweg’s Pine).—Named in 
honour of Mr. Theodore Hartweg, tho assiduous and 
successful collector for several years for tho I.ondon 
Horticultural Society, and now head gardener to tho 
Emperor of Austria. Probably Mr. Hartweg introduced 
into Britain more species of Conifora), as well as otber 
]dants, trees, and shrubs, than any modern collector. 
To him wo are indebted for tho beautiful Achimenes 
lomjijlora, and several other species. P. llartiieyii has 
a remarkable peculiarity in producing frequently only 
four leaves in a sheath ; they are very long, and thickly 
placed iqion tho branches. The tree grows slowly, and 
seldom exceeds, even on tho mountain Campanere, in 
Mexico, its native habitat, nioi’e than 50 feet higb. It 
is rather tender, but has stood out in the open air for 
several years, in Hertfordshire, at Mr. Baker’s, of Bay- 
fordbury. On account of its slow growth and great 
beauty, it is worthy of a place in the Conservatory in 
the north. T. Ai’rLEBV.

Summer Treatment. — Gutting Down. — After the 
bloom is over tho plants should bo cut down, a point of 
treatment wliicb requires some consideration. The 
form tho plants are to assume again the following 
season must bo borne in mind, and that form foreseen 
with a prophetic eye. Tho main branches should be 
thinned out and placed or left equally on every side, 
and the branches formed tho previous year should be at 
the end of each old branch. These are to produce the 
shoots for the next year. Very old wood does not break 
freely, and that renders it necessary to leave a portion 
of younger wood equally distributed over the plant. 
Tho branches that are left should bo as low as possible, 
and should not extend over the sides of the pot, but be 
cut within it. The plants will then present a curious, 
stumpy appearance, with their branches pointing out¬ 
wards on every side. No water should bo given for 
several days previously to this severe ojicration. That 
precaution will luevent a too copious bleeding, or exuda¬ 
tion of sap, and in order to continue that favourable 
state no water should be given after they are cut down 
till tho dormant buds are fairly broke. After they are 
cut down they should be protected from heavy rains, 
either by being placed in a cold-pit or under a water¬ 
proof covering. When tho buds are started then give 
them some water, but by no means a Hooding, but only 
just sulhcicut to encourage and stimulate tho very young 
shoots to progress. Should too many make their ap¬ 
pearance it will bo advisable to thin tliem, but do not 
take too many off, because then there would bo danger 
that those that are left might be accidentally broken ofl', 
and tho shape of the plant in that part would be injured. 
When these new shoots have made some progress, and 
tho plants are moderately clothed with leaves, they may 
then be fully exposed to tho open air and gentle showers. 
A top-dressing of soil would then -be of great use.
