Hyacinthus 



(430 ) 



hybridising 



to 3" of earth should lie above the crown of the 

 bulb, and in localities where the spring is usually 

 cold and late a still greater depth is advisable, as 

 it tends to keep growth back until the weather is 

 favourable. If frosts threaten when the young 

 growths are appearing, a 1" mulching of Cocoanut 

 fibre, or, failing that, of old, dry horse droppings, 

 -win ward off the danger.

HYACINTHUS. 



Botanically a rather small, but in other respects 

 a highly important, genus of handsome flowering 

 bulbs (ord. Liliaceic), including the popular 

 Hyacinths. The genus includes Bellevalin, 

 Hyacinthella, and Peribcea. The species .are 

 -rarely grown, but. some of them are' elegant^ 

 hardy plants, that like a light, rich soil and a 

 sheltered, but not heavily shaded, position. In- 

 crease is by offsets from the bulbs, and by seeds.

HYBERNIA. 



A genus of slender-bodied moths whose larvae 

 often work great havoc amongst the foliage of 

 fruit and forest trees. These larva; are all of the 

 "looper" form. Perhaps the most destructive of 

 the genus is the Mottled Umber Moth, H. defoli- 

 aria. Leucopliscaria, the Spring Usher, preys 

 upon the Oak, and aurantiaria (Scarce Umber 

 Moth) and rupicapraric, upon the Hawthorn. In 

 all cases the pupa? hybernatc in the ground under- 

 neath the trees from which they have dropped. 



Remedies. A dressing of quick lime or gas lime 

 to the soil beneath the trees ; sticky banding in 

 autumn, to prevent the ascent of the trunks of the 

 trees by the wingless females; and spraying in 

 spring, just as the leaves open, with Cal vert's 

 Carbolic Soft Soap 1 oz. to the gallon of soft water 

 applied lukewarm, are good. Paris Green, 1 oz. to 

 20 gallons of water, is even more effective, but 

 the mixture must be kept, continually agitated 

 during the process of spraying. Although a poison, 

 it is safe to use at this strength. 



HYBRID. 



A mule, or a cross between two species, not a 

 cross between two varieties of the >:ime species. 

 (See also HYBRIDISING.) A liigencric hybrid is a 

 cross between species belonging to different genera. 

 Thus, species of Cattleya and Lrclia have been 

 crossed with each other, and the result, a Lselio- 

 Cattleya, is termed a " bigeneric hybrid.'' Some 

 authorities hold, however, that if two species, 

 belonging to different genera, will cross, it is 

 evidence of an affinity so close that they ought to 

 be placed in the same genus. The animal mule, or 

 hybrid, is usually sterile, but this rule does not 

 hold good in the plant world. Some hybrids are 

 undoubtedly partially sterile, but others again 

 seem to be possessed of an increased share of 

 fertility. 



HYBRIDISING. 



The producing of a hybrid, or mule, by the 

 crossing of two distinct species. Although the 

 hybridiser and the cross fertiliser work baud in 

 hand, and the term ".hybridising" is frequently 

 used to cover the work of both, the work of each 

 is distinct, seeing that the cross fertiliser deals 

 only with varieties and the hybridist with species. 



Many of our races of garden llowcrs are of 

 hybrid origin, the break away from the normal 

 types having been first obtained by the fusion of: 

 two species, which resulted in a plant of more or 

 less intermediate habit. This intermediate char- 

 acter is by no means a fixture. In very few ca:-es 

 indeed are the influences of the male and female 

 parents so nicely balanced as to produce in the 

 offspring a neutral habit. Usually the hybrid 

 favours one of the parents more than the other, 

 and no law can be laid down as to the prepotency
