B. I. / ) i.Y / (.ALA CHAM.V.HI 'XL s L. The Dwarf Box Polygala, or Box-leaved 

 Milkmirt. (Jacq. Aust., t. '2'.W. ; Willis, Bot. Mag., t. 310.; and our fig. 77.) 



Dosi-ritx-d as having fruticose, branched, procumbent stems, with oblong, 

 lanceolate mucronated leaves ; the racemes 1 -.'.flowered ; the keel of 

 the flower crested. It forms a little evergreen tuft, the leaves being like 

 those uf the dwarf IH>X ; and the yellowish flowers, which are slightly 

 tipped with purple, resembling at a distance those of the order Legunii. 

 n"-sa\ It ia a native of mountainous woods in many parts of Kuroj>e, 

 jiartieularly in those of (Jermany and Switzerland. In rocky situations, 

 it seldom exceeds ii in. in height; but in heath soil, or in sandy loam 

 enriched with leaf mould, it will grow to the height of a foot and up- 

 wards, flowering freely every year. This plant has been in cultivation 

 in British gardens since 1(158. "Miller says that the seeds, which are with 

 difficulty obtained from abroad, do not vegetate till they have been a 

 whole year in the ground ; unless they are sown soon after they are ripe, 

 which is in August or September, in which case they will come up the 

 following spring. It is readily propagated, however, by division of the 

 plant, as it throws up suckers in abundance. This plant succeeds very 

 well in most gardens, in a shady situation, and in peat soil kept rather 

 moist. Intermixed with (iaulther;Yj procumbens, Mitchi'lla repens, 

 Linnw'rt lx>reulis, and other dwarf.growing shrubs, /'olygala Chamabuxus will form a rich margin 

 to American groups. The price, in the London nurseries, is Ms. a hundred ; it being frequently sold 

 in quantities for forming edgings to beds of peat-earth plants. 



* -. The half hardy Polygalas are evergreen shrubs, natives of the 

 Ca]H" of <-ood Hope ; and in Britain they are generally treated as green- 

 house plants, though some of them have stotxl against a wall, with pro- 

 tection during winter : and so great is their beauty during summer, that, 

 we think, whoever has a conservative wall ought to place some of them 

 against it. Above twenty C'ape species have been introduced ; but the 

 nioNt common are, P. oppositifMia L. J>ot. Reg., t. ftki. \ which is a native 

 of the mountainous part of the Cape, and tolerably hardy ; P. opposl- 

 tif:<liii ni'~;jur Ji. 78.), called by some P. grandiflbfa, which is equally 

 hardy, and is a fine variety; P. Intif'dia Ker, P. mt/rtif!>lia t P. gran- 

 tlijt.<r,i Ix.dd., P. hrncteolata L., P. spccinsa Bot, Mag.', and P. attc- 

 im: la I.ixld., all tine plants, with bright purple flowers mixed with 

 white, and some of them with red, ami all procurable in the principal 

 London nurseries. Like almost all other Cape shrubs, they grow best 

 in heath soil, or in a mixture of sand and leaf mould ; and, when they 

 are cultivated against a wall in the open ground, great care should be 

 taken not to let their stems l>e injured by damp in autumn, more espe- 

 cially at the surface of the ground ; or, "in technical language, at the 

 coll.tr. There are some trees and shrubs belonging to the order 7'oly- 

 galacea- in the Himalaya ; which, when introduced, will be worth trying 

 against a conservative wall with the Cape species.

OF THE HARDY AND HALF-HARDY LIGNEOUS SPECIES OF THE ORDER 

 PITTOSPORA'CgJE. 



Distinctive Characteristics. Thalamiflorous. (77. />'.) Sepals ~>, petals ~> ; both imbricate in aestiva- 

 tion. Stamens .',, distinct, alternate with the petals. Ovarium of several cells, with the placenta- in 

 the axi- ; cells or placenta' '' or ~> in number, and many-ovuled. Style 1. Stigmas as many as the pla- 

 centa-. Fruit capsular, or berried. Seeds often covered with a glutinous or resinous pulp. (Lindl. 

 In. In .V. ,S. The species contained in this order are all ligneous ; and are either trees, or bushy or 

 climbing shrubs, with terminal or axillary flowers, usually of a hell-shape, with a spreading border. 

 They are natives of warm climates; but some species of Pittosporum, Billardiern, and Solljvj, are 

 half-hardy, and suitable fora conservative wall.
