 will do.

WHEAT. 



The ancestor of this all-important cereal has 

 received the name of Triticum vulgare. Lt is 

 extremely problematical, however, whether the 

 original Wheat plant is in existence. It will be 

 noticed that the Wheat is a close relative of that 

 plague of the kitchen garden, Couch Grass, Cooch, 

 or Twitch, Agropyrum (Triticum) repens. The Buck- 

 wheat is Fagopyrum esculentum, and the Guinea 

 or Turkey Wheat, Zea Mays. 



WHITE FLY. 



In addition to being known as Black-tailed 

 Mealy Bug, White-tailed Mealy Bug, and Lantana 

 liiig, Orthezia insignis is sometimes called by the 

 distinctly inappropriate name of White Fly. The 

 Snowy Fly (Aleyrodes) is sometimes known as 

 White Fly, and here the name is certainly suitable. 

 A. Vaporariorum attacks plants under glass, and 

 A. proletella Cabbages. (For other details, xea 

 ALEYKODES and SNOWY FLY.)

W^HITE-LINE DART MOTH. 



This is the popular name given toAgrotis Tritici, 

 a member of the section of Noctua, or Night Moths. 

 The larvae are almost omnivorous, but they are 

 especially fond of the young and tender shoots of 

 the Grape Vine. They attack most strongly the 

 shoots which are nearest to the ground, eating by 

 night and hiding in the soil during the day. Hand 

 picking by lantern light is generally recommended, 

 but the larva; are difficult of detection Where 

 herbaceous plants are concerned it is advisable, 

 if the attack be a bad one, to remove the surface 

 soil with the larvse and burn it, replacing it by 

 fresh material. 



WHITFIELDIA. 



Ornamental stove herbs (ord. Acanthaceas), only 

 one species of which has been introduced. Propa- 

 gation, by cuttings. Soil, fibrous loam two parts, 

 peat one part, and sand.

WHITLAVIA (ee PHACELIJ). 



WIDDRINGTONIA. (AFRICAN 

 CYPRESS.) 



Greenhouse or half-hardy trees (ord. Conifera;). 

 Propagation, by seeds. The young plants should 

 be carefully pricked into larger pots as soon as 

 possible. Soil, light sandy loam two-thirds, and 

 leaf mould one-third. The genus is referred to 

 Callitris by Index Kercenxis. 



Only Species :
