HYBRIDIZING. 107 



The species are readily propagated by seeds, which they appear to ripen freely. 

 and we expect they may also be increased by cuttings of the half-ripened wood 

 under a hand glass. 



We have selected dentatus as being, on the whole, the most desirable species ; but 

 it forms but one of a group introduced, we believe nearly about the same time, by 

 the Horticultural Society's collector, Mr. Hartweg, and which are all well deserving 

 attention. The C. papillosus and C. rigidus are scarcely less interesting than that 

 we have figured, and are a shade more hardy ; indeed, we believe they may be said 

 to be perfectly so. The foliage of C. papillosus is much larger than that of dentatus, 

 and has its surface covered with pimple-like elevations, to which it owes its specific 

 name. It is of more vigorous growth than the Toothed Ceanothe, and may be 

 treated in a similar manner. C. rigidus fully equals in interest papillosus, but is 

 less branching in its habit. The only other species deserving general cultivation, 

 are the C. pallidus and C. cuneatus, the first with pale blue flowers, and the second 

 with white blossoms. 



One species, the C. Americanus, is known as the New Jersey Tea, from the 

 circumstance of its having been used in the American war as a substitute for the 

 Chinese plant. As we may not soon have occasion to notice this order again, it 

 may be worth while to remark that to the Buckthorn tribe belongs the Lotus of the 

 ancients, and the Jujube tree, both of them species of Zizyplius ; though the articles 

 sold as Jujubes probably contain as much of the genuine fruit as the Perfumer's 

 Bears' Grease does of the real Bruin. 



As we would not willingly incur the reproach of unfaithfulness, we feel com- 

 pelled to observe that our artist has represented the leaves of the plant as too 

 pointed. They are, however, extremely blunt, and, in addition, deeply emarginate. 



HYBRIDIZING. 



However much the mere Botanist may regret the multiplication of seminal varieties 

 of cultivated plants, it is undeniable, that to the art of the hybridizer our gardens 

 are indebted for some of their most striking features. In support of this opinion, 

 we need only cite the Dahlia, the Pansey, and the Hollyhock, which in their 

 primitive condition would hardly be tolerated by cultivators of the humblest aims, 

 but which, from the immense improvement which has resulted in their form, size, 

 and colouring, are now justly considered necessary in gardens of the smallest extent. 

 And even in the case of those plants which come forth from the hand of Nature 

 arrayed in charms which it were profanity to impeach, much has been done in
