BUL 



as well not to remove it, but insert the 

 bud in the stock just as it is cut. The 

 edges of the cut in the stock are lifted 

 and slightly pressed outward by the point 

 of the budding-knife, the bud inserted, 

 and pushed down by the ivory handle. 

 To keep the bud in place it is wrapped 

 neatly round with any soft tying mate- 

 rial, the fiber known as Eaphia being 

 the best In two or three weeks after the 

 bud has been put in it will be safe to re- 

 move the tying. All shoots starting be- 

 Imv the bud must be rubbed off as soon 

 as they start, and when the bud begins to 

 grow, the portion of the stock above the 

 graft must be cut off, so that the inserted 

 bud may get the full benefit of growth. 

 Bulb. An underground bud, consisting of 

 numerous fleshy scales placed one over 

 the other; a modified form of the leaf 

 bud. A bulb is usually placed partly or 

 entirely underground. There are seve- 

 ral kinds of bulbs, the following being the 

 most common: A Naked Bulb is a bulb 

 whose scales are loose and almost sepa- 

 rate, as in the Crown Imperial. A Tuni- 

 cated Bull) is one whose fleshy scales 

 overlap each other, forming concentric 

 layers, the outer ones being thin or mem- 

 branous, such as Hyacinths, Onions, Tu- 

 lips, etc. A Solid Bulb is properly a 

 Corm, which see. 



Bulbiferous. Bearing or producing bulbs. 

 Bulbil or BnWlus.k.n axillary bulb with 

 fleshy scales, falling off its parent spon- 

 taneously, and propagating it. Applied 

 more especially to those buds on the 

 stem, which occasionally assume the char- 

 acter of bulbs, as in Lilium tigrinum. 

 Bulbodium.The solid bulb of old botan- 

 ists; the same as a conn, which see. 

 Bulbosi Pill Hairs that proceed from a 

 swollen base. 



BUS 



Bulbosus. Having the structure of a bulb; 

 having bulbs. 



Bidb-tuber. A corm, which see. 



Bullate. Blistered, puckered; as when the 

 parenchyma (which see) of a leaf is larger 

 than the area within which it is formed. 



Bulrushworts. A name given by Lindley 

 to the Typhacece. 



Burmanniacece. A family of Monocotyle- 

 dons, which are allied to Orchids in 

 their inferior ovary, (which is either three- 

 celled or with three parietal placentas,) 

 in their trimerous flowers, (see Trimer- 

 ous, ) and especially in their minute seeds, 

 with a loosely netted testa (which see) 

 inclosing an apparently homogeneous 

 nucleus or embryo; they differ, however, 

 in their perfectly regular flowers, with 

 from three to six distinct stamens and a 

 central simple or three-cleft style. They 

 are all herbaceous plants, bearing blue or 

 white flowers, and inhabit marshy or 



. shady places. The slender annual stems 

 in some genera have no leaves except 

 small colorless scales, which led former 

 botanists to regard them as parasites; 

 but it has been ascertained that they 

 grow on rotten leaves and other decayed 

 vegetable substances, and not on living 

 plants. There are about thirty species of 

 Burmanniacece, all of which are tropical 

 except one North American Burmannia. 

 There are ten or eleven genera, including 

 Tacca, which some botanists regard as a 

 distinct family under the name Taccacece. 



Burry. Covered with hooked stiff hairs, 

 like the heads of Bur or Burdock. 



Bursicula, (adj. Bursiculate.) A small 

 purse. A pouch-like expansion of the 

 stigma, into which the caudicle (which 

 see) of some Orchids is inserted. 



Bush. A low shrub, densely branched 

 from the very surface of the ground.
