Budding Knives 



( 144 



Bulbophyllum 



and when the bud lias fairly started into growth 

 the remaining portion may be removed with a 

 sharp knife to within 1" of the bud. Care should 

 be taken that the bud and its resultant growth is 

 not wrenched out of place by high winds; to 

 prevent this, a stake may be bound to the top of 

 the stock, to which the young growths may be 

 secured. Other methods of budding which are 

 often employed for thick-barked trees are : Flute 

 or tube, and ring-budding, and the American shield 

 budding, which differs chiefly from the T, or com- 

 mon shield budding, in allowing the bud to retain a 

 portion of the wood removed with it from its parent. 



BUDDING KNIVES. 



Knives are specially designed for budding- 

 Rose and fruit trees, being provided with a 

 flattened handle tip for raising the bark. An oil- 

 or whet-stone should be used for keeping the edge 

 of the blade keen, as a rubber, though often 

 employed, gives the knife a rough edge, which tears 

 and fractures the delicate bark of bud or stock in 

 a way detrimental to a proper union. 



BUDDLEIA. 



This genus (ord. Loganiaceaj) is composed 

 principally of stove and greenhouse evergreen 

 shrubs that serve well to diversify the collections 

 in those structures. The chief hardy species is 

 globosa, but this should have a warm and well- 

 drained position selected for it in cold localities ; 

 it is readily propagated from cuttings of ripened 

 wood inserted under a hand-light and afforded 

 protection in severe weather. The tender species 

 are increased in a similar manner, but with the 

 greater heat common to the structures in which 

 they thrive. A compost of sound loam, with a 

 little fibrous peat and sand if close, suits admirably.

BUDS. 



Buds may be divided into two sections leaf 

 buds and flower or fruit buds. A leaf bud resembles 

 an embryo plant, and if placed under favourable 

 conditions for rooting would develop into a similar 

 plant to that from which it was taken. The small 

 bulbs, or bulbils, frequently produced in the axils 

 of the leaves of bulbous plants, are true buds, and 

 when they become detached from the parent stem 

 fall to the earth and ultimately root and grow. 

 Underground buds are well illustrated in the case 

 of the Potato, the tubers of which are subterranean 

 stems bearing numerous buds or eyes. 



BUETTNERIA. 



Stove shrubs (ard. Sterculiacea;) of no special 

 horticultural value. They grow well in fibrous 

 loam and coarse sand. Propagation is by cuttings 

 inserted in very sandy soil beneath a bell-glass in 

 bottom heat.

BULBINE. 



Description. Pretty plants of annual or peren- 

 nial habit (ord. Liliacese), having fibrous or bullions 

 roots and effective, rather sweet scented, flowers. 



Propagation. The bulbous species by offsets or 

 seeds ; the shrubby-habited by cuttings struck 

 under glass ; and the herbaceous plants by division 

 or suckers. 



Other Cultural Points. A rich but light sandy 

 loam suits. The Bulbines do best as green- 

 house plants, but the pots in which they are 

 grown may be plunged outside in summer. The 

 annual species, annua, may do well in warm situa- 

 tions if the seeds are sown in gentle heat in early 

 spring and the plants transferred to where they 

 are to bloom when large enough. 



Principal Species : 



alooides, 1', Ap., yel. A useful greenhouse plant 

 with a handsome head of flowers (syn. Anthericum 

 alooides). 



annua, 10", Je., yel. A pretty annual, seldom 

 seen in gardens. 



frutescens, 2', Ap., yel. Of shrubby growtli (syn. 

 caulescens). 



Other Species : 



asphodeloides, 2', Jy., wh. longiscapa, 1', Jo., yd. 



(KHH. Anthericum aspho- (SI/HS. Anthericum 



deloicles). longiscapum and A. al- 



bulbosa, 1', Je., yel. tissimum). 



latit'olia, 2', Jy., wh. (xyn. seniibarbata (srr bulbosa). 

 Authericum latifolium). 



BULBINELLA. 



These yellow-flowered plants (nrd. Liliacens) are 

 often united to Anthericum and Chrysobactron, but 

 Bnlbinella is the correct name. Both species are 

 natives of New Zealand, and need to be grown in a 

 greenhouse. 



Principal Species :

BULBOCODIUM. 



Pretty spring flowering hardy bulbs (nrd. Lili- 

 acese) bearing some resemblance to the Crocus, but 

 distinct botanically. There are few specie in 

 cultivation, and the only one available is known in 

 gardens as vernum, a handsome little plant with 

 broad leaves and purple flowers in February. It 

 likes a sandy soil, and should be protected from 

 slugs before the flowering time. It is propagated 

 by offsets or seeds. There is a pretty, but scarce, 

 variety named versicolor. The flowers are distinct 

 in their colour from Crocuses. 



BULBOPHYLLUM. 



Description. A large genus of Orchids (nrd. 

 Orchidacese), chiefly with small and rather 

 curiously shaped flowers. Very few of them arc 

 of any horticultural value, although they arc of 

 exceptionally easy culture. The flowers are in 

 most cases produced in long, many-flowered spikes 

 or racemes ; in Lobbii, however, they are borne in 

 pairs. Beccari, in addition to being a climber, is 

 noteworthy on account of its foetid odour, as well 

 as being one of the largest known members of the 

 Orchid family.
