292 CARAGANA CARPENTERIA 



the tops of walls to keep off trespassers, just as broken glass is used here. 

 It is sometimes confused with the following species (g.v.\ 



C. TRAGACANTHOIDES, Poiret. 



A low, spreading, much-branched shrub, i to \\ ft. high, described as 

 having in a wild state much the habit of Astragalus Tragacantha. Branches 

 very spiny, downy when young ; spines I to i^ ins. long, slender (modified 

 leaf-stalks) ; stipules narrow, in. long, scarcely spiny, silky. Leaves f to \\ 

 ins. long, composed of three to five pairs of leaflets, which are rather variable 

 in outline, oblanceolate, obovate or oblong, j to ^ in. in length, woolly. 

 Flower \\ in. long, yellow, solitary on a downy stalk \ to in. long. Calyx 

 \ in. long, bell-shaped, downy, and with short, triangular teeth. Pod i 

 to ij ins. long, shaggy with silky hairs, the lower half enclosed by the 

 persisting calyx. 



Native of Thibet, N. China, Siberia; introduced in 1816. It is doubtful 

 if the true plant be now in cultivation, the shrub commonly seen under 

 the name being C. spinosa, which has smaller flowers and a smooth pod 

 and calyx. C. tragacanthoides is rather variable, some forms like var. VILLOSA 

 having the young branches densely covered with shaggy grey hairs. 



CARMICHAELIA FLAGELLIFORMIS, Colenso. LEGUMINOS^:. 



A deciduous or often leafless shrub, 4 or 5 ft. high, with numerous 

 erect-growing, slender, grooved branches, flattened or convex when young, 

 round when old. Leaves very small and inconspicuous, consisting of 

 three or five tiny leaflets, which are somewhat larger in young plants than 

 in old ones. Flowers purplish lilac, pea-shaped, produced in axillary 

 downy racemes ; there are from one to three racemes at each joint of the 

 twigs, and from three to seven flowers in each raceme, the whole forming 

 a short, dense cluster. The flowers, although small (about \ in. long), 

 are borne in extraordinary profusion. Pod \ to | in. long, nearly as wide, 

 ending in a stout-pointed beak, and containing usually two seeds. 



Native of New Zealand, long grown at Kew in a greenhouse, and for 

 the last twenty years unprotected in the open ground, where, although 

 slightly injured at the younger parts in severe winters, it is on the whole 

 quite hardy, and produces both flowers and seeds in abundance. It is 

 not very showy or ornamental, but its flat, erect branches give it a quaint 

 and unusual aspect. These green shoots perform the usual functions 

 of leaves. It is not so attractive a plant as its ally, Notospartium 

 Carmichaelise, but is hardier. The Notospartium differs in its stouter 

 twigs and more pendulous habit, in its larger pink flowers, and in the 

 longer, narrower, jointed pod containing more seeds. 



CARPENTERIA CALIFORNICA, Torrey. SAXIFRAGACE^:. 



(Bot. Mag., t. 6911.) 



An evergreen shrub, 6 to 8 ft. high, of bushy habit and free growth, 

 branchlets very pithy; young bark pale and minutely downy. Leaves 

 opposite, lanceolate, 2 to 4^ ins. long, \ to i in. wide, tapering at both ends,
