Myrsiphyllum 



Naegelia 



MYRSIPHYLLUM. 



The graceful climbing plant known to florists as 

 Smilax is commonly labelled Myrsiphyllum asparag- 

 oides in gardens, but its correct title is Asparagus 

 medeoloides, which see. 



MYRTUS. (MYRTLE.) 



Description. Very ornamental stove, greenhouse, 

 or nearly hardy shrubs or trees (prd. Myrtacea. 1 ) 

 which are often prized for their scent as well as 

 for their flowers and foliage. The Common Myrtle, 

 communis, of which there are a good many 

 varieties, is hardy in some very mild districts on a 

 wall or in a sheltered position. Many of the plants 

 formerly known as Myrtles have been transferred 

 to other genera. 



Propagation. By cuttings of half-ripened or 

 older shoots under a glass in slight heat, the stove 

 species requiring greater heat. 



Soil. Sandy loam and leaf mould, or a little 

 peat. 



Other Cultural Points. Watering needs to be 

 carefully attended to, and the beauty of the plants 

 is much increased if they are frequently syringed 

 during the summer months. The Myrtles are 

 amenable to training to trellises of any desired 

 shape, and also make pretty standards.

MYSTACIDIUM. 



Tropical and South African Orchids (ord. Orchid- 

 aceai) closely allied to Angrrccum, and needing 

 similar treatment, but the more southern species 

 should have a lower temperature. Few have any 

 pretensions to horticultural value.

MYTILASPIS. 



One of the most dreaded of scale insects is 

 Mytilaspis Pomorum, known popularly as the 

 ' Apple Mussel Scale," so named because the pest 

 chiefly attacks Apple trees, and forms the scale, 

 which serves as covering to the female larva, and 

 also protects the eggs and new brood. The perfect 

 male insect has wings and an extremely brief life. 

 Trees infested must be dealt with during winter; 

 the best plan is to scrape the trunk and branches 

 with a blunt instrument, syringing with soapy 

 water and following with a good scrubbing, using 

 a still' brush and strong soft-soapy water. Every 

 effort should be made to cleanse infested trees 



during winter, following up the scrubbing process 

 by spraying the trees with either a kerosene emul- 

 sion, or caustic soda and potash mixture, the latter 

 for preference. (See INSECTICIDES.) 



MYZUS. 



Among the many genera forming the class of 

 Aphides, or Plant Lice, Myzus is one of the worst. 

 The chief species, Cerasi and Ribis, secrete honey- 

 dew, and so, besides feeding upon the juices found 

 in the leaves of Cherry trees and Black Currant 

 hushes, they cause the leaves to curl up and 

 stick together with their exudations. Forcible 

 syringing is a good remedy, using warm, soapy 

 water, with tobacco or Quassia extract added. 

 For Cherries and other subjects under glass the same 

 remedies are applicable. Under glass, if fumiga- 

 tion or vaporising be practised at regular intervals, 

 these aphides will not prove troublesome. Wall 

 trees and bushes in overshadowed positions are 

 most liable to attack. Liberal cultural methods 

 should follow treatment for the extermination of 

 Myzoa,
