Bonatea 



BOLEUM. 



A pleasing shrub (ord. Crnciferse) for the rock 

 garden. It is of evergreen habit. The only 

 species is aspernm, which grows nearly 1' high, 

 and has cream-coloured flowers. It is propagated 

 from seeds sown under glass in spring, or from 

 cuttings struck under a frame or handlight in 

 summer. It can be grown in a light soil, but 

 should not be planted where cold winds will strike 

 upon it. 



BOLTING. 



The term used in connection with the premature 

 running to seed of certain vegetables, chiefly of 

 the Brassica tribe. This condition is generally 



BOMAREA OLIGAXTHA 



brought about by a shallow root run, hot dry soil, 

 abnormally high temperatures, or unseasonable 

 sowing of seeds. Bolted Lettuces may be econom- 

 ically disposed of by cooking and serving as 

 Spinach, for which they form a very good sub- 

 stitute. 



BOLTONIA. 



Handsome border flowers (ord. Compositse), and 

 valued for cutting. Hardy herbaceous perennials. 

 Propagation is by division in spring or autumn, or 

 by seeds sown in the open or in a frame in spring. 

 Any good soil, such as is suitable for other border 

 Hewers, will do. Asteroides and its variety decur- 

 rens like a moist, and the others a dry, soil. 



Principal Species : 



asteroides, 4' or more, Jy., wh. or pk. A fine 

 plant with pleasing coloured foliage. 



decurrens, 4' or more, Jy., pale vio. The 

 largest flowered and most ornamental of the genus. 



Holivaria.(ee Menodora). 

 Bollea (see Zyyofetalum). 



Other Species : 



diffusa, 4', Aug., wh. latisquama, 3' to 5', Aug., 



bl. vio. 



BOMAREA. 



A genus of plants allied to Alstromeria (orrl. 

 Arnaryllidere), differing from the latter chiefly 

 by their twining habit. The long, twining stems 

 are furnished with smooth, slightly fleshy leaves. 

 Propagation is effected by seeds, offsets, and 

 division of the fleshy, fibrous rootstock. They 

 delight in a light and dry soil, such as sandy loam, 

 or sandy loam and peat, well drained ; but are other- 

 wise not fastidious. Most of them may be grown 

 very cool, even in a cold frame during winter, but 

 they thrive better and flower more freely in a dry, 

 moderately warm greenhouse. 



Principal Species :

 oculata).

BOMBAX. 



Mostly tall trees (ord. Malvaceae), requiring 

 stove heat. Leaves ornamental. The flowers are 

 solitary or in clusters, small, and white or red. 

 Propagation is accomplished by cuttings getting 

 firm at the base, inserted in sand, and placed in a 

 propagating case. Good, fibrous loam and a dash 

 of sand will meet their requirements in the matter 

 of soil. They should have a moist atmosphere in 

 a tall stove or warm conservatory if required to 

 show anything of their natural development.

BONATEA. 



A genus of two or three erect, stout stemmed, 

 terrestrial Orchids (ord. Orchidacea?). They an 1 

 allied to Habenaria, and have leafy stems, un- 

 divided root tubers, and large, showy flowers. 

 Propagation is effected by division of the tubers. 

 Loam and peat in equal proportions, with sand, 

 make a suitable compost. They should be grown 



liooilijx neustria. (Lackey Moth, see Apple 

 Enemies).
