results. In case of an attack of spot the 

 only thing that can be done is to remove 

 the badly spotted leaves and burn them. 

 If only a spot or two occurs on a leaf, 

 the affected portions may be cut out. 

 Never under any circumstances should 

 these leaves be thrown in the walks or 

 back of the beds, as they are always a 

 source of further infection. Cleanliness 

 in this case, as in all others with the vio- 

 let, is absolutely essential to success. 



Wat or Stem-Rot. 



Wilt, or stem-rot, is very apt to come 

 on the latter part of August after the 

 plants have attained considerable size. 

 During the warm days plants here and 

 there are seen to wilt slightly, recovering 

 after the sun goes down. This will con- 

 tinue for a week or longer, when sudden- 

 ly the plant wilts down and fails to re- 

 cover. The difficulty is due to the pres- 

 ence of a fungus in the tissues of the 

 stem. Experience has shown that infec- 

 tion in most cases occurs when the cut- 

 ting is in the bench being rooted. Little 

 black specks may be seen on the stems 

 of the rooted plants. Frequently these 

 affected areas are not larger than the 

 point of a pin and they may remain 

 practically dormant for months. In the 

 mean time the plant has been growing 

 and the fungus suddenly begins to de- 

 velop, resulting in the complete girdling 

 of the stem and the cutting off of the 

 supply of moisture and nourishment. 

 Certain kinds of sand are very apt to 

 be infected with the spores of this fun- 

 gus. This is especially true of sand 

 where there is likelihood of organic mat- 

 ter being present in it. For cuttings the 

 best material is clean bank sand. If 

 upon examination many of the cuttings 

 are found to be infested with the fungus, 

 they should be discarded and only the 

 healthy ones planted.

INCARVILLEAS. 



The incarvilleas are among the most 

 showy of our hardy perennial plants. 

 Belonging to the Bignoniaceae family, 

 they are fully as attractive as members 

 of that family cultivated under glass. 

 I. Delvayi has of late years achieved an 

 extraordinary popularity and a vase of 

 it in a collection of hardy herbaceous 

 flowers arrests instant attention. I. 

 variabilis, another variety grown to 

 some extent, was introduced in 1898, by 

 Haage & Schmidt, of Erfurt, Germany. 

 The variety I. Olgse is a native of 

 Turkestan, growing two to three feet in 

 height, with pale pink flowers, the 

 tubes being one and a half to two 

 inches long. I. Olgae is more reliably 

 hardy than I. Delvayi and I. variabilis. 

 The two latter varieties we are usually 

 unable to winter outdoors in Massachu- 

 setts, although one or two growers have 

 succeeded in doing so. A warm, sunny 

 spot, with sandy soil well manured, 

 suits these plants. If kept outside a 

 thick covering of leaves must be given. 

 The safer plan is to lift the roots and 

 store in a frame, or pack the same in 

 dry sand in a cool cellar in the same 

 way as dahlias are often preserved. 



The accompanying illustration is 

 from a plant of Incarvillea Olgas grown 

 under glass at Garfield park, Chicago.

CLIMBING FERN. 



I enclose a piece of a vine of which 

 I should like to know the name and 

 where stock can be procured. The florist 



Incarvillea Olgae. 



of whom I procured this sample says he 

 thinks it is Lygodium scandens. He has 

 only a few plants and knows of none ex- 

 cept a few he has sold from time to 

 time. It grows like smilax and is much 

 better for design work and decorating. 

 T. W. L. 



The specimen in question is a portion 

 of a frond of one of the climbing ferns 

 and is probably Lygodium Japonicum 

 instead of L. scandens. This fern is a 

 native of Japan and the East Indies, and 

 is not largely grown in the trade, al- 

 though it has been in cultivation for 

 many years. Lygodium could undoubt- 

 edly be used to advantage in design work 

 and decorating, but it will not produce 

 the same quantity of growth as smilax, 

 and cannot be grown so profitably.
