Oblong-headed trees show heads of foliage more lengthened out, more formal, and generally more tapering, than round-headed ones. They differ from spiry-topped trees in having upright branches instead of horizontal ones, and in forming a conical or pyramidal mass of foliage, instead of a spiry, tufted one. They are mostly deciduous; and approaching more nearly to round-headed trees than spiry-topped ones do, they may perhaps be more frequently introduced. The Lombardy poplar may be considered the representative of this division, as the oak is of the first, and the larch and fir of the second. Abroad, the oriental cypress, an evergreen, is used to produce similar effects in scenery.
