Pinus Grenvilleae. Nat. Ord. Coniferae

A noble Conifer, discovered by Mr. Hartweg, on some of the highest mountains near Tepic, in Mexico. It is of robust habit, and has in consequence been called "Ocote macho," or male Pine, by the natives. The foliage is very robust, from twelve to fifteen inches in length; leaves are in fives. The cones are solitary, pendulous, straight, sixteen inches long, and three to four inches across the base. This species is easily distinguishable, from its straight cones and robust foliage. In its native habitat it attains to the height of seventy to eighty feet. It has been named in honor of the Eight Honorable Lady Grenville. - Horticultural Society Journ.

Pinus Longifolia

This beautiful long-leaved species is not hardy in England, and consequently we must not expect it to be hardy here. In the more Southern States it would succeed fine, and it richly deserves the attention of southern cultivators. On its native mountains, the Himalayas, it grows much lower down than most of the other conifers; hence its delicacy. Major E. Madden says : " The tree occurs in the greatest perfection and abundance on both mountains (Siyahee and Bin6ur), and, indeed, seen from any commanding elevation, Outer and Central Kumaoon and Gurhwal, north to the Pindur, from 2,500 to 7,000 or 7,200 feet elevation, appear little else than one great forest of Cheer* Pine, succeeded at that level by Oaks".

Pinus Strobus Pendula

This variety was taken out of a bed where the seed had been planted seven years ago; it has the character of a weeping Pinus Strobus, and was raised by Mr. Heimburg, Vice-President of the Horticultural Society in Mainz, who is entitled to the thanks of all lovers of weeping trees, for having increased their number by such a graceful specimen.

How frequently are such discoveries lost or unnoticed by careless observers, which for centuries may not be again produced. We are therefore indebted to Mr. Heimburg for having brought this rarity to notice, and for introducing it to our collections. - Deutsches Magazin, Stuttgard.

Piracy

We can pay no attention to your statement, until you give us your name, or the name of the book referred to. We make it a rule to require the name of all correspondents, when we have to rely upon their good faith for the accuracy of their information.

(T. E., Barnebville, O.) We would recommend you Allen's Treatise on the Grape - price, we think, 81,25; Chorlton's Treatise, 50 cents; and Leuehar's on Hothouses, etc, about $1,25. You may get them in Cleveland or Cincinnati Derby, the publisher in the latter place, keeps a good assortment of such works.

The Pitch Pine. Pinus Rigida

For the purpose of creating a wild and somewhat romantic effect upon some rocky hillside, or in the formation of a broken group, the pitch pine may be used with good effect; but as a tree for general use in ornamental planting, the dark rich green of its foliage, and the facility with which it can be grown in any soil, are its only claims to notice.
