Tliis plant, although long cultivated, is not known in a wild 

 state. It is believed to be of Chinese origin, and it is not un- 

 common in the gardens of Pekin. In general appearance, iji 

 the shape of the leaves, the size of the flowers and in 

 tlie period of blooming, it is intermediate between 6' vulgaris 

 and -V. Pcrsica. This is one of the hardiest and handsomest 

 shrubs in cultivation, producing its enormous rather kix clus- 

 ters of flowers in the greatest profusion. There are varieties 

 with rosy pin'pleand with white flowers. 



4. S. Persica, L. Lea^■es ovate, lanceolate, narrowed 

 into an acute, sometimes mucronate point, entire or rarely 

 pinnatifid, the base contracted into a slender petiole; 

 thyrsus loose, the flowers spreading ; calvx with four 

 obtuse lobes ; tube of the corolla long and slender, the 

 ovate lobes with inflexed margins slightly spreading; 

 anthers included ; fruit linear, obtuse or apiculate, smooth. 



Syringa Persica has long been an inhaliitant of the gardens 

 of Persia and India, whence it was introduced into Europe 

 and America. Its native country, however, was longimknown 

 until it was met with by Dr. Aitcheson, of the Afghan Bound- 

 ary Survey, who found it " a very common shrub on the low 

 and outer hills near Shalizan up to nearly 7,500 feet."* Varie- 

 ties with lilac and with white flowers are common. 5. 

 ptcridifolia is a variety in which the leaves are deeply laceni- 

 ate. 



* * Leaves pale on. the under side. 



5. 6". rillosa, A'ahl. Young shoots smooth, slightly 

 striate-angled, conspicuously marked with oblong white 

 spots; leaves broadly obvate-lanceolate; contracted at the 

 base into a short, stout, grooved petiole, and with scab- 

 rous margins and conspicuously reticulated veins, the pale 

 under side, especially along the principal veins, covered 

 with long, slender, scattered hairs ; thyrsus elongated, 

 narrow and often interrupted ; calyx smooth or sfightly 

 pubescent, the short, obtuse lobes much shorter than the 

 tube ; lube of the pale, rose-colored corolla slender, four 

 times the length of the calyx, the oblong lobes with 

 strongly inflexed margins erect or spreading ; stamens in- 

 cluded. 



Syringa villosa M-as discovered near Pekin about the middle 

 of the last century by the French missionary, d'Incarville. It 

 was found in the same region by David, and plants raised 

 from seed sent to the Arnold Arljoretum from Pekin by Dr. 

 Bretschneider are now growing here. To this species should 

 perhaps lie referred, as M. Franchet hints in his paper upon 

 the Chinese Lilacs,t 5. Josikcpa and 5. Einodi, which, as he 

 points out, cannot be separated from d'Incarville's plant either 

 by the shape of the leaves, the character of the inflorescence, 

 or liy the shape and size of the flowers. In the Himalaya plant 

 (5. Einodi), however, the long, white hairs wliich cover the 

 imder side of the leaves of 5. villosa, are replaced by a minute 

 puberulence on the mid-rib, which is even less developed on 

 the leaves of 5. Josikcea. The bark, color and markings of 

 the young shoots and tlie habit of these three plants are iden- 

 tical, although in S. Josikcea the leaves are narrower than in 

 the Chinese plant, l:>ut not narrower than tliose of many Hima- 

 laya specimens. The plants of S. Josilccra, now widelv dis- 

 tributed in gardens, have all been i)ropagated from a s'ino-Ie 

 plant discovered in a Hungarian garden'^ but not Icnown' to 

 be wild in Europe, and probably of Asiatic origin. 



6. 6". pubescens, Turcz. Leaves ovate, three or four 

 ribbed, cuneate at the base, one and a half to two inches 

 long, pale-green above, pale below, the mid-rib distinctly 

 pubescent ; calyx smooth, with short, triangular, some- 

 times minutely mucronulate lobes; tube of the pale, 

 rose-colored corolla very slender, six times longer than

 fruit obliquely oblong, verrucose.

Leaves persistent. 



7. S. scnipcrvireiis. Leaves coriaceous, short-petioled, 

 ovate or suborbiculate, entire; cyme few-flowered; calyx 

 cup-shaped, obscurely crenate; tube of the short corolla 

 white, three times as long as the calyx. The lobes finally 

 reflexed, thick, obtuse; anthers inserted in the middle of 

 the tube; style slightly bifid; fruit drupaceous, with two 

 cells ; one aliortive, the other containing at maturity a 

 single, oblong, irregularly incurved seed. 



Syringa sctnpcrznrens, Franchet, Bull. Soc. Linn., Paris, 

 No. 77, p. 613, was discovered liy the French missionary, the 

 Abbe Delavev, at an elevation of 7,500 feet in the mountains 

 above Tapintze in Yun-nan. It has not been introduced into 

 cultivation.

8. S. Aniurensis, I^up. Leaves ovate or oblong, obtuse 

 or acuminate, contracted into a long, channeled petiole; 

 thyrsus densely flowered ; calyx sub-membranaceous, 

 smooth, irregularly toothed ; tube of the corolla included 

 in the short calyx; the lobes obtuse; fruit oblong, obtuse, 

 smooth. 



Syringa .Unurcnsis is a hardy shrub six or eight feet high, 

 with white, fragrant flowers ; a native of ManchmMa. 



9. 6". Pekinensis, Rup. Leaves ovate or deltoid, obtuse 

 or acuminate, rounded at the base or contracted into the 

 long, slender, channeled petiole, dark green and opaque 

 above, lighter on the under side ; thyrsus densely flow- 

 ered ; calyx obscurely denticulate ; tube of the white 

 corolla barely longer than the calyx; fiuit smooth, linear- 

 oblong, acute, or slightly beaked at the end. 



Syi-inga Pekinensis is -a native of tlie mountains of northern 

 China, where it was discovered by David. It is growing in the 

 Arnold Arboretum, where it was raised from seed sent by Dr. 

 Bretschneider from Pekin, but as yet has shown no disposition 

 to flower. It is here a slender, tree-like shrub, perfectly hardy, 

 and already ten to twelve feet high, with long, graceful, 

 flexuous branches, covered with a smooth, yellow-brown bark, 

 not very unlike that of a Cherry tree. A plant with distinctly 

 weeping branches appeared among the seedlings raised in the 

 Arboretum. 



10. .S". faponiea, Maxm. Leaves broadl)' ovate, acu- 

 minate, contracted into a sharp point, rounded or slightly 

 cuneate at the base, smooth above, villous-pubescent on 

 the under side ; thyrsus many-flowered, calyx puberulous 

 denticulate; tube of the corolla included in the calyx, the 

 lobes thickened on the margins, apiculate; the smooth 

 fruit oblong, obtuse. 



Syringa Japonica is a native of Japan. It has been culti- 

 vated in the Arboretum for a number of years, where it makes 

 a handsome small tree. 



11. S. rotundifolia, Decne. Leaves orbicular, abruptly 

 acuminate at the end, cordate or rounded at the base ; 

 panicle many-flowered; calyx membranaceous, slightly 

 denticulate, tuJie of the corolla included in the calyx, the 

 lobes ovate, obtuse.

A Tropical Garden. 



THERE was published in one of the early issues of 

 G.\RDEN AND FoREST ail illustration showing the en- 

 trance of what may be called, perhaps, a typical New 

 England garden, or rather of a garden in which some of 

 those forms of plant life typical of the vegetation of 

 north-eastern North America — the \Miite Pine, the Hem- 

 lock, the Oaks, Maples and the Hickories— are conspicu- 

 iiusly displayed as Nature often groups them. Our illus- 

 tration on page 223 of the present issue represents the 

 entrance of a garden almost at the other extremit)' of the
