PEROWSKIA PETTERIA 1 29 



Native of the Himalaya and Afghanistan. It covers large areas in the 

 Chitral Valley, to the exclusion of other vegetation. Although woody at 

 the base, the stems made during the summer die back considerably 

 during winter. It should be planted in good loam, in a group of at least 

 half a dozen plants, and then makes a strikingly pretty effect in late 

 summer. A heat-lover, it should have the sunniest position available. 

 The plants should be pruned over in spring, cutting off the dead portion 

 and perhaps a little more. It rarely produces seed with us, but can 

 easily be increased by July cuttings. 



PERTYA SINENSIS, Oliver. COMPOSITE. 



A deciduous bush, 4 to 6 ft. high, with glabrous, slender, ribbed 

 branches. Leaves alternate on the shoots of the year, ovate-lanceolate, 

 long and taper-pointed ; 2 to 3 ins. long, f to i in. wide ; deep green, 

 usually with one to three sharp teeth on each margin, but sometimes not 

 toothed. On the year-old branches they are produced four to six together 

 in rosette-like clusters from each joint, and are only half or less than 

 half the size of the others, and without teeth. The 'leaves are either 

 smooth or have some small bristles on the midrib; stalks \ in. or less 

 long. Flower-heads pinkish purple, |- in. across, surrounded by a series 

 of oval, membranous, overlapping bracts ; they are produced from the 

 centre of each leaf cluster on the year-old shoots, each on a slender, 

 slightly bristly stalk about \ in. or more long. It flowers in June 

 and July. 



Native of Hupeh, China; discovered by Henry in 1889, and intro- 

 duced by Wilson in 1901 for Messrs Veitch. It is a neat shrub, but 

 of more botanical than garden interest. The leaves have an intense, 

 Quassia-like bitterness. The chief interest of this shrub is in its 

 being an addition to the few shrubby composites that are hardy in 

 cultivation. 



PETTERIA RAMENTACEA, PresL DALMATIAN LABURNUM. 



LEGUMINOS.E. 



(Cytisus Weldcnii, Visiani ; Bot. Keg. 39, t 40.) 



A deciduous, tree-like shrub of sturdy habit, 6 or 8 ft. high, closely 

 allied to Laburnum and Cytisus. Leaves trifoliolate, with a slender stalk 

 i to i-|- ins. long; leaflets oval or obovate, very shortly stalked, i to 2 ins. 

 long, half as much wide, rounded at the apex, smooth. Racemes ter- 

 minating short twigs of the year, erect, ij to 3 ins. long; flower-stalks 

 short, hairy. Flowers fragrant, densely arranged, yellow, f in. long, 

 resembling those of a 'broom ; calyx tubular, downy ; standard petal 

 erect. Seed-pod ij to 2 ins. long, pointed at the end, dark brown when 

 ripe, containing five or seven seeds.
