seedlings of C. Ardoini. The pollen parent was evidently C. purgans, which 

 it resembles in leaf and stem ; its semi-prostrate habit it inherits from 

 C. Ardoini. It flowers in May, and is then one of the prettiest of dwarf 

 brooms ; it is, however, at its best when two or three years old. 



C. DALLIMOREI, Rolfe. 



(Bot. Mag., t. 8482.) 



A hybrid raised at Kew in 1900 by crossing C. scoparius var. Andreanus 

 (seed-bearer) with C. albus. It is a tall shrub, perhaps 8 or 9 ft. high, of thin, 

 erect habit, suggesting that of C. scoparius. Leaves mostly trifoliolate, downy, 

 young wood ribbed. Flowers about f in. long, the whole of the petals suffused 

 with beautiful shades of rosy pink deepening on the wing-petals to crimson ; 

 the almost orbicular standard petal is f in. long, darker outside than within, 

 keel almost white. Calyx helmet-shaped, shining brown, slightly downy, \ in. 

 long ; flower-stalk \ in. long, downy. At each node the flowers are solitary or 

 in pairs. 



The beautiful broom is quite distinct from any other in cultivation, and is 

 the first hybrid broom raised by artificial cross-fertilisation, all its predecessors 

 having originated as chance crosses made by insects. It is propagated by 

 grafting on Laburnum. As it flowers regularly and in great profusion in May, 

 it ought in time to become a popular garden shrub. 



C. DECUMBENS, Spach. 

 (Bot. Mag., t. 8230.) 



A prostrate shrub, 4 to 6 ins. high, with five-angled, sparsely hairy 

 branches. Leaves simple, stalkless, to in. long, oblong or obovate, \ to \ 

 in. wide ; hairy, especially beneath. Flowers bright yellow, \ to f in. long, 

 produced singly, in pairs, or in threes from the joints of the preceding summer's 

 shoots ; the flower-stalks are J to \ in. long, and the calyx \ in. long, both 

 hairy. Pod to i in. long, hairy, three- or four-seeded. 



Native of S. Europe from France to Albania and Montenegro. This 

 species is, perhaps, the most prostrate of all brooms in cultivation, lying as it 

 does flat on the ground and only increasing in height by additional growths 

 laid on the older ones. In May and June it is very gay with the bright but rich 

 yellow flowers. It may be strongly recommended for the rock garden, 

 especially for positions where it is in full sunlight. Said by Aiton to have been 

 introduced in 1775, but now rare in gardens. 



C. HEUFFELI, Wierzbicki. 



(C. supinus var. Heuffeli, Briquet?) 



A low, deciduous shrub with slender, erect, or arching branches covered 

 with greyish appressed hairs. Leaves trifoliolate, with stalks \ in. long ; 

 leaflets \ to f in. long, \ in. or less wide ; linear oblong or linear obovate, 

 covered with flattened hairs beneath ; ultimately smooth above. Flowers 

 borne on the shoots of the year in a close terminal head, each f in. long, with 

 narrow, yellow petals, and a very hairy calyx which extends two-thirds the 

 length of the flower. Pod I in. long, ^ in. wide, covered with silky greyish 

 hairs, and containing four to eight seeds. 



Native of Hungary and the Transylvanian Alps. Jt belongs to the 

 C. supinus group, characterised by the terminal inflorescence, the long hairy
