Synopsis of Plant Kingdom 



Key to Identification of Plants This is a device to enable 



' one to find the name of a 



plant. The name thus found is quickly referred to under its 



alphabetical location, where full information will be found in 

 regard to it. 



This is one of the most im- 

 portant features of the new 

 edition. It constitutes a general running account of the classes, 

 orders, and groups of plants, with a brief sketch or character- 

 ization of 215 of the leading families comprising those that 

 yield practically all the cultivated plants. These family de- 

 scriptions give the botanical characters; the number of genera 

 and species and the ranges; a list of the important genera; 

 brief statements in regard to the useful plants; and diagram- 

 matic illustrations. 



Illustrations There are 24 colored plates; 96 full page half- 

 tones ; and more than 4,000 engravings which 

 serve as guides in the text. 



The Glossary This is an analysis of all technical terms that 

 are used in the work and in similar works. 

 It comprises botanical and horticultural terms with brief defl- 

 nitions.

CLUB AND SOCIETY NOTES. 

 The regular monthly meeting of the 

 Mount Kisco (N. Y.) Horticultural So- 

 ciety was held on Tuesday. April 10. 

 Mr. Gordon and Mr. Connolly exhibit- 

 ed. The former received 90 points for 

 lily of the valley and 80 for schizan- 

 thus, the later for sweet peas 80 

 points, carnations 75, stocks 60 and 

 mushrooms 80. James T. Scott, of 

 Elmsford, talked on Roses, which was 

 certainly enjoyed. Mr. Scott accorded 

 a standing vote of thanks. All ex- 

 hibits of flowers were sent to the local 

 hospital. In May, Jliss Martha H. 

 Miller will talk to us on some topic, 

 probably in the afternoon.

At the monthly meeting of the 

 Sewickley (Pa.) Horticultural Society 

 on April 10 the Constitution was 

 changed to read, "Persons who have 

 furthered the interests of horticulture 

 in connection with our Society, may be 

 elected honorary members, and it was 

 resolved to invite a number of resi- 

 dents of Sewickley interested in the 

 Society to become honorary members, 

 M. Curran, J. Barnet and A. Ethering- 

 ton were appointed schedule commit- 

 tee for the coming September show, 

 and a motion was carried that the 

 Society would finance the purchasing 

 of seeds for the school children com- 

 peting at the same show. It was 

 agreed to send the monthly exhibits 

 to the Sewickley Valley Hospital. 

 There was an interesting discussion 

 on the best varieties of apples and 

 other fruits.

INSECT AND ANIMAL PESTS OF 

 THE GLADIOLUS 



From Cornell Extension lUilU-tin liv .\Ifred 

 C. llottes. 



It seems safe to say that there is 

 really no insect that is seriously in- 

 jurious on the gladiolus. Dora brain 

 (1873) reports serious damage in Eng- 

 land due to wireworms. He believes 

 that freshly turned-up sod should not 

 be used, and writes as follows: "Three 

 years ago I planted mine in a part of 

 my garden which had up to two years 

 before that been a meadow, and the 

 previous season had potatoes in it. 

 Half my roots were devoured by wire- 

 worms, the destructive little things 

 eating through the shoot just as it ap- 

 peared above ground." W. P. Wright 

 also mentions wireworms, in Popular 

 Garden Flowers. He states that the 

 grubs fasten on the corms in myriads, 

 and soon make short work of a large 

 collection. He recommends that if the 

 corms are planted on new land from 

 pasture, the turf should be taken away, 

 not turned in. however deeply, and in 

 the spring before planting Vaporite 

 or Aporite should be dug in nine or 

 ten inches below the surface. 



The writer has seen no reference to 

 injury from wireworms in this coun- 

 try. Weather (1911) recommends 

 trenching three feet deep in autumn, 

 burying the topsoil containing the 

 worms, and perhaps other grubs, at 

 the bottom of the furrow. By this 

 practice the worms are completely 

 stified and deprived of their vegetable 

 diet; the subsoil will thus be free from 

 the pest, and if well manured and ex- 

 posed to the weather it will be in a 

 good fertile condition in the spring. 



The writer has noted a slight 



amount of injury due to the small wiry 

 millepede. Chilognatha. This may be 

 the "wireworm" already referred to. 

 The millepedes may be observed in the 

 ashes under pots of gladioli grown in- 

 doors, and many of them are also no- 

 ticed on the outdoor corms at the time 

 they are being overhauled for winter 

 storage. The condition known as scab 

 may be due to these millepedes, but 

 this is not definitely proved. If the 

 corms are left to dry in a barn for 

 some time, the holes bored by the mil- 

 lepede are filled with a jelly-like sub- 

 stance which one might at first think 

 is frost. The injury due to these mille- 

 pedes differs from diseased corms in 

 that the areas of their attack are of 

 regular shape and are metallic in ap- 

 pearance. 



Most of the damage to gladioli 

 caused by insects is on the parts of 

 the plant above ground. The black 

 aster beetle seems troublesome to many 

 growers, the damage being to both 

 buds and flowers. This is especially 

 true late in the season. 



H. A. Richardson reports the occur- 

 rence of arctiid moths, undoubtedly a 

 species of the genus of tiger moths, 

 Eyprepia. These moths are gregarious 

 in habit, and they injure the flowers 

 and spikes, but mostly the cuticle of 

 the leaves. Grasshoppers and katy- 

 dids have been reported as eating the 

 blooms. 



The red spider (Tetranychus telarius 

 Linn.) is especially troublesome in a 

 very dry season. This is a small mite, 

 one-fiftieth of an inch long, which 

 spins minute threads that are scarcely 

 perceptible to the naked eye but that 

 when very abundant give a grayish 

 appearance to the leaves. The insects
