Bunchosia 



(148) 



Burtonia 



members of the genus (ord. Sapotacese) were 

 formerly in cultivation, but now only about three 

 are grown.

BUNCHOSIA. 



Stove shrubs (ord. Malpighiacese) of some orna- 

 mental value. Canescens attains to tree form. 

 Cuttings of ripe growths root in very sandy soil in 

 heat. A mixture of fibrous loam and peat with 

 sand is the best.

BUNIAS. 



A few small growing plants constitute this 

 genus (ord. Cruciferse), but they are of no special 

 horticultural merit. Hardy. 



Principal Species : 

 Erucago, Je., Jy., yel. orientalis, My., Je., yel. 



(syn. aspera). 



BUPHANE. 



Bulbous plants (ord. Amaryllides;), well adapted 

 for greenhouse culture, with rather handsome 

 flowers. The cultivation they require is the same 

 as that of the Brunsvigias, to which they are 

 allied, and which should be referred to for cultural 

 directions. The species are ciliaris. 9", purple, 

 and disticha, 1J', October, pink. The former is 

 also known as Amaryllis, Hiemanthus, BruBSvigia, 

 and Coburgia ciliaris ; and the latter as Amaryllis 

 disticha, Haemanthus toxicarius, and Brunsvigia 

 toxicaria: 



BUPHTHALMUM. 



Showy, hardy herbaceous plants (ord. Com- 

 positse)," of much value in the garden. They are 

 propagated by division of the roots in spring or 

 autumn, or by seeds sown in spring in the open or 

 in a cold frame. They like a rich soil, and a fairly 

 sunny position in the border. The following are 

 the best of the genus which are in cultivation :-

BUPLEURUM. (HAKE'S EAH.) 

 A rather large genus (ord. Umbellifera) of annual, 

 herbaceous, or shrubby plants for the border, rock 

 garden, or greenhouse. Few are of horticultural 

 value, and they can hardly be recommended except 

 to those who like to grow plants more noteworthy 

 for their curiosity than beauty. The annuals are 

 propagated by seeds sown in spring; the peren- 

 nials by seeds or division, the latter in autumn or 

 spring; and the greenhouse shrubby species by 

 cuttings or seeds. A dry soil of a rather sandy 

 character is necessary.

BURBIDGEA. 



Of this genus (ord. Scitaminea;) nitida, a 

 beautiful stove herbaceous perennial, is the only 

 species. It grows about 3' in height, and pro- 

 duces orange red flowers in summer. Propagation 

 is readily effected by division. Soil, loam, leaf 

 mould, peat, and sand. 



BURCHELLIA. 



A small genus (ord. Rubiacese) of stove ever- 

 green shrubs that delight in a mixture of fibrous 

 loam, peat, and coarse sand. They must have 

 good drainage, and be watered with care. Cut- 

 tings of half-ripened shoots root well in sandy soil 

 in heat. 



Principal Species :

BURLINGTONIA (ee RODKIGUEZIA). 



BURNET. 



In olden times Burnet (Poterium Sanguisorba 

 and P. officinale) was a much more popular herb 

 than nowadays, and had a place, in one or other of 

 its species, in the herb border of every well- 

 appointed garden. The leafage has a very cooling 

 effect, and a flavour resembling Cucumber ; and 

 for these reasons it was much employed in the 

 production of an old English drink known as "cool 

 tankard." The generic name is a reminder of this 

 usage, as it is from the Latin potermm, a drinking 

 cup. 



BURSARIA. 



Bursaria spinosa is an attractive evergreen shrub 

 (ord. Pittosporese) for the greenhouse ; it flowers 

 profusely if grown in sandy loam and peat 

 in equal parts. Propagation, by cuttings of 

 the young shoots in sand, in heat. 10', October, 

 white. 



BURSERA. 



A small genus (ord. Burseracere) of stove trees 

 that are said to possess some economic value, and 

 are used for hedges in South America. Cuttings 

 root readily under a hand-glass in very sandy soil 

 over bottom heat. Soil, peat and loam in equal 

 proportions. 



Principal Species: 

 australasica, 20', Je., wh. gummifera, 20', Je., wh. 



gm. gn>- 



BURTONIA. 



This small genus of greenhouse evergreen shrubs 

 (ord. LeguminosiB) abhors stagnant moisture, and 

 must be grown in loam, fibrous peat, and coarse 

 sand, over perfect drainage. Propagation, by cut- 

 tings in sand beneath a bell-glass, or by seeds when, 

 procurable.
