Not only were the branches above the ring' largely devel- 

 oped by the arrest of the descending sap and also the limbs 

 below seemingly siirunk to the size of a pipe stem, but the 

 renewal-canes appeared to have an enfeebled growth. It was 

 evident that thesavingof the crop was likely to prove a serious 

 injury to the health of the vineyard. But this was an extreme 

 practice, where the crop had evidently been treated as of prime 

 importance, and the renewal-cane had been neglected. But 

 this by no means- determines whether a judicious use of this 

 method may not often prove harmless and of great practical 

 advantage. Our native Grape is so superabundant in the pro- 

 duction of foliage that checking becomes necessary. The fact, 

 also, that a large amount of old wood has to be removed 

 every autumn, has a bearing upon this question. Add to these 

 the consideration that the renewal-cane, imder proper encour- 

 agement, will give a large supply of nourishment to the root, 

 and it does not seem unreasonable to conclude that a moder- 

 ate portion of the descending sap may be arrested just below 



as near the light as possible, and during the months of Decem- 

 ber and January, wheft Orchid bloom is always welcome, 

 large, bold blossoms of ivory whiteness and of good sub- 

 stance will develop themselves very rapidly and remain in 

 good condition for several weeks. 



Dendrobium Wardianum. — This is a winter blooming spe- 

 cies, and its very free flowering qualities, combined with its 

 easy culture, make it a most desirable Orchid. It is decidu- 

 ous, and succeeds best at the warmest end of tlie Cattleya 

 house, close to the light, either in pots or baskets. It does not 

 enjoy too much pot room, its thin, aerial roots preferring the 

 outer surface of the pot or basket which it occupies. When 

 the growths are fully matured the plant should be removed to 

 a much cooler and drier atmosphere, enough water only 

 being given to keep the bulbs from shriveling. About the end 

 of September and beginning of October the plant may be 

 removed again to its blooming quarters, when large and very 

 handsome blossoms, each measuring some tliree inches in

the fruit without material injury to the vine. Indeed, the case 

 which has been here cited, and many similar ones which are 

 known, so far from disproving, rather go to prove that a weAl- 

 considered and moderate girdling would often result in 

 decided advantage. At all events, it is desirable that there 

 should be continued experiments in this direction.

Ccelogyne cristata.—Th\s is one of the most popular of all 

 the white flowering Orchids, its blossoms being pure and 

 very handsome. It made its appearance in European gardens 

 nearly lialf a century ago and has always been greatly admired. 

 Several varieties have flowered since its introduction, among 

 them being the very rare C. cristata alba {hololeuca), with 

 blossoms of the clearest white, and now only to be seen in 

 select collections. Two other varieties, one called the Chats- 

 worth variety and the other known as C. cristata maxima, are 

 both large forms, the latter having broad, flat sepals and petals, 

 and a large lip with a bright, golden-yellow crest. This also 

 remains somewhat rare. In its native country it is found 

 growing at an elevation of 6,000 to 8,000 feet above sea level, 

 and where the atmosphere at all seasons is very cool. Large 

 specimens of this Ccelogyne are often met with, a fact which 

 clearly indicates it to be a species of easy cultivation. When 

 growth commences the plants should occupy a cool situation 

 until the newly made bulbs are fully matured, after which thev 

 should be removed to the warmest end of the Cattleya house 



diameter, will make their appearance almost the entire length 

 of the pseudo-bulbs, during December and January, and 

 remain in good condition for from four to six weeks. Im- 

 ported plants of this Dendrobium arrive in the market dur- 

 ing February and March and are easily established. With, 

 good drainage and very little potting material, they will yield 

 quite a display of bloom the following winter. .A D.

Phalanopsis denticiclata is a new species, flowermg for the 

 first time with us. It evidently belongs to the Sumatrana sec- 

 tion, though robust in growth. It bears short, erect, few- 

 flowered racemes ; these are yellowish-white, barred and 

 blotched with cinnamon brown ; the lip is streaked with vio- 

 let, the anterior lobe white and papillose. It grows verv 

 freely with us, extending its roots in all directions, delighting 

 in abundance of water and strong heat. 



Saccolabium giganteiim. — This is a beautiful Orchid intro- 

 duced from BuriTjah. It is easily grown and of rolnist habit, 

 with an erect, stout stem, closely clasped by broad, lovate 

 leaves about one foot long, dark green, with streaks of 

 lighter shade. The flowers are produced on dense racemes, 

 about a foot long and pendulous. They are pure white, 

 speckled and blotched with amethyst. The lip is amethyst, 

 with lines of a lighter siiadc. This plant is probably only a 

 variety of .S". violaceiiin, a species introduced more than a 

 century since under the name of Vanda densiflora. In the 

 latter the leaves are narrow and longer, while the flower is of 

 a mauve violet on a white ground. A pure white variety of this 

 is called Harrisonianum, and is somewhat rare. All of these
