464 CYTISUS 



but with stalks up to f in. long on the stronger, non-flowering ones. Leaflets 

 very variable in shape, often obovate, but also oval, roundish, or oblate, from 

 j to f in. long, pointed. Flowers four to ten, in short racemes terminating 

 short side twigs of the year, bright yellow, in. long, expanding in June. Pod 

 ij ins. long, | in. wide, smooth. 



Native of S. Europe and N. Africa ; introduced about three hundred years 

 ago, and one of the most attractive of the later-flowering brooms. It is more 

 appreciated on the Continent than with us, and gives some of the brightest 

 effects seen in German gardens in June. 



C. SUPINUS, Linntzus. 

 (C. capitatus, Scopoli.} 



A deciduous shrub, 2 to 4 ft. high, with round, erect, hairy branches. 

 Leaves trifoliolate, with a main-stalk about- \ in. long ; leaflets obovate or 

 elliptical, very hairy beneath, ultimately smooth above, \ to I in. long. 

 Flowers in a terminal cluster or umbel 2 ins. across, each flower nearly I in. 

 long, with bright yellow petals ; calyx tubular, \ in. long, very hairy. Pod 

 \\ ins. long, \ in. wide, covered with shaggy hairs. 



The shrub here described must be taken to represent a considerable group 

 of brooms found in a wild state over an area reaching from Spain in the west 

 through the south of Europe to Turkey in the east, all characterised by a 

 terminal umbel of flowers and hairy stems, leaves, calyx, and pods. It is a 

 group which in its largest sense includes C. Heuffeli and C. leucanthus, but 

 these being distinct enough to be readily recognised are here described 

 separately. In a restricted sense it must include C. AUSTRIACUS, Linnczus, 

 which differs in having the hairs on the shoots, calyx, and pods appressed. All 

 the members of this group flower on the shoots of the year in July and August, 

 and intermittently until the frosts come. Whatever pruning, therefore, is 

 necessary, should be done in spring before growth recommences, when the 

 last made shoots may, if desired, be cut back almost to the old wood. 



C. SUPRANUBIUS, O. Kuntze. TENERIFFE BROOM. 

 (Bot. Mag., t. 8509 ; C. nubigenus, Link ; Spartium nubigenum, Linnceus.') 



A shrub 8 to 10 ft. high, of broom-like habit; twigs stiff, stout, ribbed, 

 clothed with white hairs at first, soon smooth. Leaves of three leaflets, each 

 J to ^ in. long, ^ to ^ in. wide, with a main-stalk of about the same length ; 

 inconspicuous or absent. Flowers borne in May in axillary clusters on the 

 previous season'sjshoots; they are milky 'white with a tinge of rose, ^ in. long; 

 standard petal roundish obovate, ^ in. long; calyx and flower-stalk hairy. 

 Seed-pod brown, i to i J ins. long. 



Native of the Canaries, and very abundant on the Peak of Teneriffe. It 

 was cultivated at Kew seventy years ago, but is too tender to withstand hard 

 winters there. It is, however, so beautiful and so distinct that it is much to 

 be recommended for the milder parts of the kingdom. At Glasnevin, Dublin, 

 it is 8 ft. high in the open, producing the effect of an evergreen through the 

 dark green of its numerous branchlets which resemble those of Spartium 

 junceum. They are, therefore, very much stouter than those of the common 

 white broom C. albus. 



C. VERSICOLOR, Hort. 



A hybrid, of which C. purpureus is'one parent and either ratisbonensis or 

 elongatus the other. It has inherited the characters and general aspect of 

 C. purpureus, having smooth stems and similar foliage,. but is a sturdier, taller,
