ARBORETUM AND FRUTICETUM

PART III,

App. i. Species of Pine having Two Leaves in a Sheath, whichwe cannot with certainty refer to any of the preceding Sections.

P. Afassom&na Lamb. Pin., ed. 2., 1. t. 8.» If. Du Ham., 5. p. 243., Willd. Sp. Pi., 4. p.497.,Laws. Man., p. 348.; ? P. nepalensis Cels. Leaves in pairs, very long, and slender ; sheaths short.Crest of the anthers dentate-lacerate. (Lamb.) Bud apparently like that of P. sinensis. Leaves6 in. long, slender; sheaths £ in. long, white, membranaceous, with brown scales at the base. Malecatkins numerous, fin. long. A tree, a native of China, and probably identical with P. sinensis.Mr. Lambert’s plate is from a specimen in the Banksian herbarium, brought by Mr. Francis Massonfrom the Cape of Good Hope, where it was raised from seeds which had been sent from China.Neither cones, seeds, nor living plants, have yet been introduced under the name of P. Massonidwa,-but Mr. Lawson observes, “ on comparing a plant received from M. Cels, nurseryman, Paris, underthe name of P. nepalensis, with Mr. Lambert’s figure and description of P. Massomdraa, there seemslittle doubt but they are the same. In habit of growth and general appearance it resembles P. lon-gifblia, but differs in having only two leaves in each sheath, whereas the latter has three. Theplant, however, above referred to, has not attained sufficient size to show whether its leaves willbecome so pendulous as those of the long-leaved East In-dian pine.” There is a plant of P. nepalfensis in the pine-turn at Haddo House, of which the Earl of Aberdeenhas sent us a specimen, but the leaves are in threes.

P. Massonidna Professor Don considers, as we have seenin p. 2218., nothing more than P. Pinaster; and, withrespect to the P. nepalensis received from Lord Aber-deen, it is probably P. longifblia.

Pi nus sp.,from Nepal. Some cones of a pine havebeen kindly sent us by Mr. Paxton, which were broughthome from the East Indies in 1837, by a collector sentout by His Grace the Duke of Devonshire. The conesresemble those of P. Pinaster in the termination oftheir scales, but they are much smaller ; the largest is2f in. long, and 2 in. broad; and the smaller ones,and the seeds and their wings, resemble Jig. 2117. Noleaves were brought home; but Mr. Paxton informsus that the general appearance of the tree, on its nativehills, was like that of an old, stunted, weatherbeatenScotch pine; it having, like that tree, dark heavy fo-liage, rather dense. All thetrees the collector saw hadthat character, except one or two which were growingmore freely, and had more the appearance of cedars ofLebanon; only that the branches did not spread somuch at bottom; though they had the habit of thattree, the head tapering on every side, from the extre-mity of the bottom branches upwards to a point Theheight to which the tree grows is estimated at between30 ft. and 40 ft. As the cones bear so close a resemblancein their scales to those of P. Pin&ster and P. Pinea,we have noticed them in this Appendix, rather thanunder any of the sections of 3 or 4-leaved pines, towhich, however, the species may ultimately be foundto belong. As the seeds are fresh, young plants will soon be raised ; and these, in a few years, willenable us to decide at least to what section the tree belongs.

Sect. ii. Ternatcc.—Leaves 3 in a Sheath.

A. Cones hardly so long as the Leaves; the Scales with Prickles.

§ v. Tce'da.

Sect. Char. Leaves 3 in a sheath, longer than the cones. Cones in twos, threes,or clusters, with the scales prickly. The trunk and larger branches throwout tufts of foliage and abortive shoots, even in the thickest parts, and inevery stage of the tree’s growth. Natives of North America. — The kindsbrought together in this section, though generally considered species, may,possibly, be only varieties. Though the pines belonging to this division areeasily known by the cones, and even by the leaves and buds, when the treesare mature and seen together; yet we have found none so difficult to deter-mine by their leaves and buds, when the plants are young. In genera], theleaves of P. TsS da are longer, stronger, and of a more glaucous hue; and itsbuds are larger than those of any other kind in the section. P. rigida hasshorter leaves, fewer of them, and they are less glaucous; and the buds arelong, cylindrical, and blunt-pointed. P. serotina resembles P. rigida in theleaves, but these are still fewer, and the cones are egg-shaped. The P.variabilis of Lambert, according to his figure, is different from any of these,and in no way resembles the P. mitis of Michaux, of which it is said to be asynonyme. TheP.mitis of Michaux is known with certainty at first sight, byits numerous, thickly set, and slender, short leaves; and, above all, by the
