that is not easily destroyed. The name, pandurata, is 

 taken from an occasional form of the leaf, as shown in 

 the illustration, known as " panduriform. " But the 

 most common form of leaf — in some localities the only 

 form — is heart-shaped, nearly like that of the common 

 morning glory. The flower is large and white, with a 

 purple throat. It opens in the night, and usually fades 

 the next day. New buds develop daily, and a succession 

 of flowers is maintained ; but instead of bearing thous- 

 ands of blossoms at one time, rarely more than ten or a 

 dozen flowers appear on a single plant. In some locali- 

 ties, notably in 

 southern Penn- 

 sylvania, these 

 plants are so 

 plentiful that 

 they make it 

 difficult to till 

 the soil. Their 

 large tubers grow 

 two or three feet 

 into the sub-soil, 

 far below the 

 reach of plow or 

 cultivator. It is 

 almost impossi- 

 ble to extermi- 

 nate them by 

 cultivation. 



The Calystegia 

 sepiiim^ which 

 Mr. Childs says 

 the Ipoiiiaa pan- 

 durata is ' ' un- 

 doubtedly con- 

 founded with," 

 is a plant of en- 

 t i r e 1 y different 

 habit. Its vine 

 is more slender 

 and always 

 climbing, where- 

 as the ipomoea 

 frequently runs 

 along the ground. The form of leaf is quite different, 

 as may be seen by comparing this with the two illustra- 

 tions. The flower is not so large as that of the ipomcea, 

 and instead of pure white it is decidedly tinged with 

 pink, especially when old. The throat is not purple, 

 but pure white. This characteristic alone is sufficient 

 to distinguish the one from the other. At the base of 

 the flower, and completely enclosing the calyx, are two 

 large, loose bracts not found on the ipomoea. It is a 

 bad fraud, perhaps unintentional, but a fraud for a' 

 that.— Geo. H. Shull, Ohio. 



Box Borders Redivivus. — In your beautiful illus- 

 tration of a charming Newport garden page 518, I no- 

 tice the grand forms of trained box or tree box [Biixiis 

 arborea), also B. sempervi7-ens, and varieties such as ro- 



Calystegia sepium. 



tundiflora, thymifolia, macrophylla and myrtifolia. 

 Also Argentavariegata , or silver edged, and Folia aiirea, 

 the golden tree box. These varieties are quite distinct 

 from the box formerly used so much for edging or 

 bordering in flower and kitchen gardens. Years ago no 

 nice appointed garden was complete without the formal 

 box edging. This is Biixus friiticosa, of which there 

 are two distinct varieties, one being termed the English, 

 which is a very stiff form ; the other is the old Holland 

 Dutch variety. This is more soft and of a denser habit, 

 and therefore preferable to the English. Your corres- 

 pondent in his 

 remarks upon 

 the box and box 

 edging, says that 

 these have of 

 late gone out of 

 use on account 

 of the introduc- 

 tion of new sorts, 

 and partly on ac- 

 count of the fact 

 that such stiff 

 and angular 

 pathways are 

 now seldom tol- 

 erated. Perhaps 

 your correspon- 

 dent is not 

 aware, however, 

 that of late, with- 

 in the last two 

 and three years, 

 some of our 

 ablest landscape 

 architects have 

 again introduced 

 this old fashion- 

 ed style of box 

 edging, b u t in 

 the more modern 

 forms of English 

 geometric and 

 old Dutch box 



gardens, and in the modern flower garden as edging, be- 

 cause they have not found anything so well adapted for 

 that purpose : nor has anything yet been introduced to 

 take its place. It is still a favorite because of its sterling 

 qualities of shapeliness, tidiness, its close and dense 

 growing habit, its adaptability for being trimmed into 

 proper shape, its freedom from insects, and lastly its 

 evergreen and fresh appearance, even in mid-winter 

 when all else is bare and bleak, which alone is enough 

 to give it the prestige which is now accorded it. I have 

 had the pleasure of seeing it introduced of late in some 

 of the largest and choicest pieces of landscape art in 

 this country, and to my personal knowledge there are 

 now growing for this very purpose thousands upon 

 thousands of yards. Of course it is not used in the
