Berchemia 



(119) 



Berteroa 



be specially named on account of its foliage as 

 being one of our best dark-leaved shrubs ; this is 

 vulgaris foliis-pm-pureis. Many of the dwarf er 

 spri-ii's are handsome as permanent bedders of on 

 rock work. 



Principal Species :- 



A(]iiifolium, (>', Ap., yel, (.//. Mahonia Aqui- 

 foliuin). One of the most useful of all the 

 Berberises, growing in any soil, and producing 

 Plum-coloured berries. .It is largely used for game 

 coverts. Several vars.. of which gracilis, Herveyi, 

 and moseriana are good. The var. fascicularis is 

 also known as B. fascicularis and Mahonia 

 I'aM-icularis. 



buxifolia, 8', Mch., yel., ev. A very neat grow- 

 ing shr., of erect habit and with small flowers. 

 The dwarf form called nana makes a good shr. 

 for the rockery (/.. dnlcis, rotundifolia, and 

 microphylla [of some]). 



Danvinii, 'A' to In', My., or., ev. Perhaps the 

 prettiest Barberry we have. Very ornamental, 

 with its glossy, spiny leaves and yel. blooms. 



stenophylla, 3', My., yel., ev. This (see p. 118) is 

 reputed to be a hybrid between Darwinii and 

 empetrifolin, and is a handsome plant, effective 

 because of its foliage, flowers, and dark pur. 

 berries. There are now some pretty seedling forms. 



vulgaris, 7' to 18'. Ap., yel. Its great beauty 

 lies in its or. sc. fruit, which is sometimes used for 

 preserving. There are a good many forms, in- 

 cluding some with fruit of a different colour from 

 the type : blk., wh.. vio., pur., and yel. fruited 

 plants can be had. The pur. leaved form is very 

 effective. Many of the reputed species can only 

 ! considered forms of vulgaris. 



wallichiana, 6', My., yel., ev. This is a hand- 

 some Barberry, with pretty leaves and flowers, and 

 large vio. pur. berries (sijn. Hookeri).

BERCHEMIA. 



With the exception of volubilis, which is a 

 hardy deciduous climber from Carolina, these are 

 evergreen greenhouse twiners (ord. Khamnese), that 

 may be propagated by cuttings or seeds. A com- 

 post of loam, peat, and .-and will be found suitable.

BERGAMOT. 



A delicious perfume extracted from the rind of 

 the fruit of Citrus Aurantium Bergamia, a small 



member of the Orange family. In its best form it 

 is produced by rolling the fruit over a vessel 

 studded with sharp spikes, the oil liberated from 

 the broken glands being collected in the hollow 

 handle. Poorer qualities are obtained by rasping 

 and pressing the rind. Other plants, by reason of 

 their aroma, have received the name of Bergamot; 

 notably the handsome Monarda didyma of gardens, 

 Mentha odorata, and the Wild Bergamot (Monarda 

 fistulosa). 



BERGERA (see MUERYA). 



BERGIA. 



A genus of shrubs or sub-shrubs (ord. Elatinene) 

 principally from India, South Africa, and Australia, 

 and of little value for the garden. They require 

 greenhouse or stove *emperature, and light, rich 

 soil. The genus is propagated by seeds or cuttings 

 in heat. 



BERKHEYA. 



A South African genus (ord. Composite) com- 

 prising greenhouse evergreens and herbaceous 

 biennials. The former are raised from cuttings^ 

 and the latter by division and seeds. A light 

 loam with coarse sand forms an excellent rooting 

 medium.

BERLANDIERA. 



A herbaceous, perennial plant (ord. Composite), 

 needing the shelter of a greenhouse. It is raised 

 from seeds sown in spring. The flower heads 

 are remarkable for their persistence. Lor.m, leaf 

 soil, and sand meet its requirements so far as 

 compost is concerned. 



Principal Species : 



tomentosa, 2', My., Je., dull yel. 



BERRY. 



For descriptive purposes botanists have divided 

 the various fruits or seed vessels into groups, and 

 " berry," or " bacca." is the general title of one 

 group. A berry is a fruit full of pulp, frequently 

 edible, either by man or beast, and containing the 

 seeds in the- pulp. Common examples of the berry 

 are seen in Grapes, Currants, Tomatoes, Goose- 

 berries, and Potato apples. The Raspberry and 

 Strawberry fruits are not true berries, but, in 

 botanical language, the- former is a combination 

 of achenes and drupels and the latter a fleshy 

 receptacle. 



BERRYA (also spelled BERRIA). 



A small Indian tree (ord. TiliaceaV) that maybe 

 accommodated in a stove, and potted in loam and 

 peat. It yields the " Trincomalee Wood " of 

 commerce. 



Only Species : 



Ammonilla, HO'. Aug., wh. 



BERTEROA. 



Hardy or half-hardy flowers (ord. Crucifenc), 

 similar to the Alyssums in appearance, and now- 

 included with them. They are propagated by seeds
