borne in great trusses. La Tour d'Auvergne has deliciously- 

 scented reddish-lilac-coloured flowers ; very free-flowering. Pyra- 

 midale is very choice ; colour pale lilac. Leon Simon has 

 medium-sized flowers, light pink, suff'used with mauve. Alphonse 

 Lavallee is another first-rate variety, with pale lilac flowers 

 borne very freely. Michael Buchner is a beautiful variety, with 

 well-shaped flowers, pale lilac, margined with rose. Virginite 

 should not be overlooked : its large trusses of delicate pink 

 flowers are very attractive. President Grevy should be included 

 in a list of good Lilacs. 



TiLiA. — The Limes are favourite park trees, but there are 

 several kinds that are not so well known as they ought to be. 

 The common Lime, or Linden Tree {T. europcea), is a first-rate 

 avenue tree, and stands hard pruning well. A rich rather moist 

 soil gives the best growth, and it prefers a somewhat sheltered 

 to an exposed situation. T. argentea {T. eiiropoea alba, T. 

 tomenfosa) (the Silver Lime) bears delightfully-fragrant yellowish- 

 white flowers ; it varies in height from 40ft. to 50ft. It is 

 very distinct by reason of the under-surface of its cordate leaves 

 being covered with white pubescence, which creates a pretty 

 effect when they are disturbed by wind. T. cordata {T. syl- 

 vesfris, T. parvifolid) is a small-leaved species, and very late 

 in coming into flower. It succeeds in dry soil better than 

 most of its congeners. T. platyphyllos requires plenty of room 

 to develop. It is free in growth, with a tall erect stem and 

 rather drooping branches. It flowers early in the season. 

 T. p. asplejiifoiia, although not so vigorous as the type, is, 

 nevertheless, very ornamental. Its leaves are much cut, the 

 central portion yellowish-green, intensifying to deep green towards 

 the edges. It is an abundant blossomer. T. ame7'icana (Bass 

 Wood) delights in a cool, moist, rich soil. It is more robust 

 than T. eiiropcea, from which it differs also by reason of larger 

 and deeper green leaves, as well as being nearly a month later 

 in coming into blossom. T. a. pubescens is a very ornamental 

 variety, more dense in growth than the last-named, and also 

 conspicuous for its large leaves. 



Ulmus (Elms). — There are several kinds of Elms useful for 

 the garden as well as the park. Passing over those that are 

 well known we would direct attention to a few that are less 

 familiar. U. canipestris antarctica aurea ( U. Rosseelsii) is a free- 

 growling variety, with rich yellow foliage. U. c. latifolia variegata 

 has its foliage mottled and striped with silver and grey. 17. c. 

 viminalis variegata is very distinct, having small leaves splashed 

 . and spotted with white on a pale green ground. Amongst Wych 

 Elms, the golden-leaved variety named U. inontana fastigiata 

 aurea {U. Dampieri Wredei) is conspicuous. It is of erect 

 habit and keeps its colour throughout the growing season.
