Spec. Char., Sj-c. Stems ascending. Leaves, calyxes, and pods somewhat 

 hairy from spreading down. Leaves trifoliolate and petiolate. Leaflets 

 roundish, obovate. Flowers terminal, from 2 to 8 together. (Dec. Prod., ii. 

 p. 157.) A prostrate shrub, with trailing branches, the ends of which grow 

 upright; found in stony places on Mount Caucasus. Introduced in 1820, 

 and flowering in August. 



sk 26. C. na^nus Willd. The dwarf Cytisus.

Spec. Char., Sfc Stems cylindrical. Leaves tri- 

 foliolate, obovate, clothed with strigose pubes- 

 cence beneath, and smooth above. Raceme 

 terminal, secund, usually 4-flowered. Calyx 

 deeply 3-parted; hairs on the stems and pe- 

 duncles adpressed. {Don's Mill., ii. p. 157.) 

 A procumbent shrub, a native of the Levant ; 

 flowering in June and July. Introduced in 

 1816. This is a beautiful little shrub for rock- 

 work; and if planted in dry sandy soil, covered 

 with broad flat stones to retain the moisture 

 during the hot weather of July, it will continue 

 flowering during the whole of that month, and 

 produce abundance of seeds ; which may be 

 sent to any distance in the pods. 



§ vi. Chrondnthus Dec. 



Derivation. From chronos, a year, and anthos, a flower ; applied to this section because the petals 

 remain attached to the calyxes all the year. 



Sect. Char. Calyx with the upper lip bifid, and the lower one trifid ; lobes 

 acute, of the same length as the tube. Petals permanent. Legume oval, 

 much compressed, 2-seeded. {Dec. Prod.,ii. p. 157).

Spec. Char., 8;c. Stems erect, hairy. Leaves almost sessile, trifoliolate, hairy ; leaflets linear, acute. 



Flowers large and yellow, subterminal, on short pedicels, and few. The flowers and pods are both 



glabrous. Calyx hairy, more 5-cleft than bilabiate. {Dec. Prod., ii. p. 157.) A shrub, from 2 ft. 



to 3 ft. high, a native of the Levant. Introduced in 1818, and producing its large persistent yellow 



flowers in June and July. 



App. i. Hardy Species of Cytisus not yet introduced. 



Though we believe that by far the greater number of the cytisuses de- 

 scribed by botanists are mere varieties, and that some of the sorts are mere 

 names copied by one botanist after another, an unavoidable practice in the 

 progress of science ; yet, we deem it advisable to add the following descrip- 

 tions, that the plants may, if possible, be brought together, and studied in the 

 same garden. 



C. arbbreus Dec. ; Spartium arbbreum Desf. Atl., 2. p. 131. t. 177. ; Genista pendula Poir. Voy., 2. 

 p. 208. Branches striated and glabrous. Leaves petiolated ; leaflets obovate, clothed with fine pu- 

 bescence beneath. Flowers axillary, aggregate, pedicellate, and nodding. Pods clothed with closely 

 pressed silky down. A shrub, 8 ft. to 10ft. high, with a trunk about the thickness of a man's arm. 

 {Dec. Prod., ii. p. 154.) Found in valleys near Algiers, by Desfontaines. 



C. Weldeni Visiani, Pi. Dalm. ex Bot. Zeit., Jan. 1830, p. 52. Upright. Leaves stalked, and dis- 

 posed in threes; leaflets elliptic, entire, wedge-shaped at the base, and obtuse at the apex, smooth. 

 Flowers in terminal racemes, stalked, pyramidal, and straight. Pedicels hairy. Calyxes cam- 

 pan ulate, 3-lobed ; lobes edged with down. Corolla glabrous, but the keel clothed with silky hairs. 

 Pod glabrous and pointed. An upright-growing shrub, from 2 ft. to 4 ft high ; a native of Dalmatia, 

 in woods and on mounts. The flowers are yellow and fragrant. {Don's Mill., ii. p. 155., adapted.)
