Garden and Forest. 



[July 



but differing from this one only in the markings and color of 

 Hower, and requiring the same treatment. They are natives 

 of Burmali. 



Plialanopsis Pariskii. — An exceedingly choice little Orchid 

 with thick, fleshy roots and distichous tufts of pale green 

 leathery leaves about four inches long. The racemes, whicli 

 are large for the size of the plant, bear eight to ten flowers, less 

 than an inch across, sepals and petals pure white, lip three- 

 lobed, the lateral ones small, yellow, with purple blotches, the 

 front one broad, flat, and of deep amethyst purple. It is an 

 exceedingly free blooming kind ; the smallest piece will pro- 

 duce at least two racemes, and the charming contrast of color, 

 in the dense mass of flowers, renders it very attractive. It is a 

 native of Burmah, and grows best on block or raft of wood. 

 It should at no season lie allowed to be dry, and delights in 

 abundance of heat and moisture in the growing season. 



MiUonia PJialccnopsis. — This is the smallest of the half dozen 

 species popularly known as Odontoglossums, but now referred 

 to Miltonia. It has oblong, compressed liidbs, bearing narrow, 

 grass-like leaves about a foot long. Strong bulbs will produce 

 three to four spikes, each bearing three to four flowers, pure 

 white, the broad pandurate lip having two large broken 

 blotches of purplish crimson. This species is a native of 

 Guatemala, and is thriving \\'itli us under tlie treatment recom- 

 mended for M. vcxilhxrhuu. 



riialiTnopsis spi'ciosa Iinpcratritri- is a distinct variety of a 

 very showy species, producing panicles of bright rosy purple 

 flowers, excei)ting a white tuft of hairs on the apex of the lip. 

 The back of the flowers is faintly striped with rose. 

 Another choice and rare variety is Christyana, in which the 

 purplish flowers are lianded with pure white. These, with the 

 type, are native of the Andaman Isles, and therefore need the 

 warmest house, and should at no time lie allowed to become 

 dry. Sphagnum moss, with a few lumps of fibrous peat, is 

 the l)est potting material. 



Dcnh-ohiitm Dcarci is one of the best of recent additions to 

 fliis large genus. The racemes, usually eight to ten flowered, 

 proceed from opposite the axils of the leaves or from the old 

 leafless bulbs, in profusion, bearing' comparatively large, pure 

 white flowers, reliex'ed with just a dasli of pale green on Ijase 

 of lip. These will remain in perfection fully four months, ami 

 apparently without injury to the plant. The old bullis, though 

 adding nothing to the licauty of the plant, should be allowed 

 to remain on, as they will continue to give racemes for many 

 years. The cultural requirements of this species has not been 

 generally mastered, as good examples are the exception. It 

 does well in the warmest house the whole year, lieing satu- 

 rated with water during growth, antl at no time l.ieing very dr\-. 

 It requires little potting material.

Notes from the Arnold Arboretum. 



Ledum latifoliiiin, the Labrador Tea, is now covered with its 

 handsome heads of white flowers. It is a dwarf evergreen 

 shrub, which grows in cultivation to a height of one or two 

 feet, with erect, very leafy stems, and oblong, linear leaves with 

 revolute margins and covered on the under side with ferrugine- 

 ous wool. An inhabitant of cold swamps, it is a peat-loving 

 plant, and a good subject for the margins of Rhododendron 

 beds. Although a plant from the far north, being found from 

 Labrador to Puget Sound, like most broad-leaved evergreens, 

 it is the better in this climate for a slight winter covering. 



The Sand Myrtle {Leiophylhim lutxifoliuiii) is also in flower. 

 It is a handsome dwarf evergreen shrub, only a few inches 

 high, very common in sandy Pine-barrens from New Jersey to 

 Florida. It has minute,' olilong, veinless leaves, and profuse 

 white or rose-colorei-l flowers in terminal umbel-like corymbs, 

 made conspicuous liy the brown or purple anthers. The 

 variety (var. prostratiim) which is found only on the summits 

 of the Roan and other high Carolina mountains, where it forms 

 dense wide carpets, flowers here nearly two weeks earlier. It 

 is hardly more tlian an inch high and has deeper green leaves 

 than the New Jersey plant. 



Among all the Mountain Ashes, American, Eurojiean and 

 Japanese, none is so handsome as Pyrtis sainbiicifolia, the 

 most northern of the American species and only just reaching 

 the eastern United States on the highest of the New England 

 mountains and the shores of Lake Superior. The oblong-oval 

 divisions of the leaves are much broader than in the other 

 species ; the petioles and peduncles are a brighter red and the 

 fruit is much larger and higher colored. It makes a fine 

 tree in cultivation, especially far north ; and in the gardens of 



Minnesota and Wisconsin, where it is often seen and where it 

 soon grows into fine large specimens, it is, in autumn, an ob- 

 ject of surprising lieauty. It is rarely met with at the east, 

 however, although well suited to the climate of New England 

 and New York ; and its more general cultivation is worth the 

 attention of nurserymen. It is in every way the superior of 

 the European Mountain Ash, which is the species found in 

 American nurseries. 



DapJine alpina, a native of the European Alps, is very hand- 

 some when covered with its pure white, abundant, fragrant, 

 sessile flowers. It is a dwarf shrub, not more than a foot high 

 here, with deciduous leaves. It requires a slight winter pro- 

 tection to insure an abundant crop of flowers, as the plant is 

 not entirely hardy here. 



Fendlcra riipicola is an interesting plant of the Saxifrage fam- 

 ily, related to Deutzia, and a native of ourTexano-New Mexican 

 region, lieing found growing sparingly in the rocky crevices of 

 river bluifs from the Guadaloupe to New Mexico. It is a low 

 shrub, two to four feet high, with small, opposite, entire, 

 sub-sessile leaves, and large white, showy flowers with long, 

 conspicuous stamens, solitary on the extremities of stout 

 lateral branches. Fcndlera is perfectly hardy here, and a real 

 acquisition to the lis of dwarf garden shrubs whicli can be 

 grown in this climate. 



Among Barlierries with racemose flowers of the vulgaris 

 section are several species or varieties in the collection worth 

 more general cultivation. Perberis Canadensis is the only 

 native representative of the family in eastern America. It is 

 a graceful and very hardy shrub, a native of the mountains of 

 Virginia and Carolina. It is in every way a smaller plant than 

 P. viilgaris,\\\\\c\\ it otherwise closely resembles, except that the 

 teeth of the leaves are less bristly pointed and the racemes 

 are fewer flowered ; the berries are oval, while in the Euro- 

 pean plant they are oblong. It is a perfectly hardy plant, 

 which will grow wherever the common Barberry will thrive. 



Perberis Sinensis, a native of northern China, is one of the 

 most ornamental of the whole genus, especially when the fruit 

 is ripe. It is a graceful plant, four or five feet high, with long, 

 slender, flexuous branches, quite loaded at this season of the 

 year with slender racemes of small yellow flowers. The 

 leaves are small, spathulate or linear obovatc and quite entire, 

 or on young plants with scattered teeth ; the fruit is the largest 

 and niost brilliant in color produced liy any Barberry in the 

 collection, while, imlike Perberis vulgaris, the foliage turns in 

 autumn to birilliant orange and scarlet. 



Perberis cniarginata is a Siberian species, and one of the 

 latest to flower in the collection. It has lanceolate-obovate, 

 ciliately serrate leaves, and racemes of pale flowers. It is 

 worth general cultivation for the beauty of its autunni foliage, 

 which far exceeds that of any of the Barlierries here in the bril- 

 liancy of its coloring. There is a very distinct variety of the 

 common Barljerry in the collection from Afghanistan, with 

 stout erect branches, and spathulate leaves four or five inches 

 long, borne on long, slender petioles ; and another from 

 Hakodate, in Japan, with bright coriaceous leaves, and pale 

 flowers in semi-erect racemes. 



Perberis uinbellata, a native of the Himalayas, is'a very dis- 

 tinct late blooming species, quite hardy here, and of no little 

 ornamental value. The long, graceful, sparingly leaved 

 branches are bright red, as are the slender three-parted spines, 

 slender peduncles and pedicels. The peduncles are erect, 

 three inches long or more and twice the length of the obovate- 

 oblong, entire or slighfly toothed, mucronate leaves, which 

 are dark-green above and pale on the lower side ; they bear 

 jiear their summit a racemose umliel of long-pediceled, large, 

 pale yellow flowers. The upright, umbellate inflorescence 

 is quite unlike that of any other Barberry in the collection. 

 Perberis Cretica is still later in bloom. It is a species from 

 Asia Minor and quite hardy here. The drooping racemes of 

 pale yellow flowers are rather shorter than the oval, entire or 

 somewhat serrated leaves. It has stout, erect stems, three or 

 four feet high, armed with short three or five branched spines, 

 and soon forms a dense compact mass of handsome, dark- 

 green foliage. It is well worth general cultivation. 



Perberis concinna, a beautiful and very distinct little species, 

 is also in flower. It was discovered many years ago in the 

 Lachen Valley of theSikkim-Himalaya, at an elevation of 12,000 

 to 13,000 feet, by Sir Joseph Hooker, who introduced it into cul- 

 tivation, and who published a description and figure (/. 4744) 

 of it in the Patanieal Magazine. It does not, however, seem 

 very well known in gardens, and was not included by Lavalee 

 in the catalogue of the plants in the Arboretum Segreiziamun. 

 or by Mr. Nicliolson in his excellent •• Dictionary of Gardening." 

 Perberis concinna is a small, low bush, with erect or spread- 

 ins: bright red branches, one or two feet high, armed with
