PUBLICATIONS BEOEIVED. 



't"Sander's List of Orchid Hybrids," new edi- 

 tion. Compiled and published by Sander & Sons, 

 St. Albans, England. Size, about 6x9^ Inches; 

 158 printed pages, besides an equal number of 

 Interleaved blank pages, for the convenience of 

 the user of the book In keeping his own hybridiza- 

 tion records. Price, bound in half leather, 1 

 guinea.] 



This, of course, is not meant to be 

 a book for everybody, in all branches 

 of horticulture. It is not expected that 

 every florist will clamor for a copy. 

 Many members of all departments of 

 the trade might indeed find such a work 

 of reference highly serviceable to them, 

 but it is intended primarily and princi- 

 pally for specialists, for those most 

 special of specialists, the orchid hybrid- 

 izers. These devoted orchidists will 

 undoubtedly be eager to own it, since 

 the lack of it would be a serious handi- 

 cap to them. A book that is designed 

 for a distinct class of business men, if 

 designed - with adequate skill, is likely 

 to be almost indispensable to that class. 



Typographically the book presents a 

 good appearance. It is a creditable 

 sample of the printers' art and bears 

 every evidence of accuracy. It also 

 seems to !>», fluffi(}iMtly"''eomprehensive 

 and up-to-date to cobnrm the truth of 

 the publishers' statement that, in pro- 

 curing the matter for the new edition, 

 "all records were searched up to July 

 18, 1915." For many years Sander & 

 Sons have collected and arranged such 

 data, at first for their own use, and the 

 successive issues of this book have em- 

 bodied the results of these labors. 



The book is divided into two dis- 

 tinct sections. The first section con- 

 tains an alphabetical list of the hy- 

 brids, with the two parents and the 

 names of the raisers, when procurable. 

 In the second section the parents are 

 listed alphabetically. Thus the hybrid- 

 izer, or would-be hybridizer, has in 

 this book the means of ascertaining 

 exactly what has already been done in 

 tha line of experimentation in which 

 he is interested. By consulting this 

 book he can know his materials and 

 conduct the work intelligently, not en- 

 tirely at random. 



NEW GIANT SIALLOW. 



To create a flowering plant the blos- 

 soms of which measure one foot across 

 ^njore than three times as large as the 

 original common wild flower from 

 which it has been developed — is an 

 achievement of Bobbink & Atkins, the 

 result of over seven years of experi- 

 ment. 



"We began," said F. L. Atkins, 

 "with the wild marsh mallow, which 

 covers the New Jersey marshes in pro- 

 fusion in the late summer. We se- 

 lected the best specimens that could be 

 found, and crossed them with the best 

 examples we had of Hibiscus coccineus. 

 The next year we took the healthiest 



Hybrid Marsh Mallow Railed by Bobbink & Atkins, of Rutherford. 



specimens of this hybrid and fertilized 

 them from each other. Each year this 

 process has been continued, until about 

 two years ago, when we began to see 

 the remarkable results." 



At the nursery of this firm, at Buth- 

 erford, N. J., there are whole fields of 

 this giant marsh mallow, the height 

 ranging from six to nine feet, each 

 stem bearing a multitude of huge blos- 

 soms and each section of the fields a 

 different tone of color. The colors 

 range from pure white, through the 

 delicate varieties of pink to the deep- 

 est crimson. There are flowers of solid 

 color, others which are white or pink. 



with a red center, and some in which 

 the variations of shade resemble the 

 iris. The leaves are of large size, are 

 of a rich, glossy green, and in them- 

 selves form a unique decorative feature. 

 The New Hybrid Giant-flowering 

 Marsh Mallow is the name by which it 

 will be known. The intention of its 

 growers was to produce a hardy peren- 

 nial of such size as to form a back- 

 ground for other plantings. With the 

 coming of frost the stem dies down, 

 and, it cut off close to the ground, the 

 plant, being absolutely hardy, needs "o 

 protection, shooting up with vigor the 

 following year. 



STEM-BOT OF OABNATIONS. 



How to Prevent It. 



Having read many articles concern- 

 ing the cause of stem-rot of carnations, 

 and having been successful in prevent- 

 ing the disease myself, I venture to 

 offer my opinion on the subject, in the 

 hope of giving some slight assistance 

 to my fellow growers. I have been 

 growing carnations for over ten years, 

 in various climates and under many 

 conditions, and yet I am not aware that 

 I have ever lost a plant on account of 

 this disease. 



To be successful in resisting the 

 disease, you must begin at the time the 

 plants leave the cutting bed. When 

 potting the young plants, never bury 

 the roots deeply; about one inch be- 

 low the surface is enough. After being 

 potted, the plants should be lightly 



shaded for a few days and then allowed 

 to have full sunlight. When they at- 

 tain a height of six or seven inches, 

 break them off at a joint, leaving about 

 four inches. This is important, as if 

 long stems are allowed to grow, the 

 wood gets hard and will not make the 

 desired bushy plants. 



Danger in Deep Planting. 



Now the plants should either be re- 

 potted into 4-inch pots, to be trati's- 

 ferred to benches later, or planted out 

 in the field. In either' case be particu- 

 lar to keep the ball of the plant just 

 level with the surface of the soil, for 

 in deep planting lies danger. Keep the 

 soil well stirred through the summer, 

 to let the air circulate. 



When ready to plant in the houses, 

 have the benches whitewashed with hot 

 lime and filled with good soil. Slightly 

 shade the glass with a mud mixture.
