VINES, HARDY AND TENDER 367 



Propagation. It is very readily increased by taking the little 

 tubercles which form on the vine and sowing them in rows in the 

 open, without supports. The tubers, which form underground, may 

 also be taken, cut up into small pieces and treated in the same way. 



BRYONIA (Bryonopsis). B. laciniosa is a slender cut- 

 leaved annual vine, with rather handsome red fruit the size of a 

 cherry, beautifully marked with white. It is grown principally as 

 a warm greenhouse plant. 



Propagation. Raised from seeds, which may be sown out of 

 doors end of April. 



CAMPSIS (Tecoma. Trumpet Vine). C. chinensis {grandi- 

 flora) differs from our native C. radicans in having very much larger 

 flowers. It makes a very showy vine when in bloom late in Summer. 

 A good plan to show ofiE this vine to advantage is to grow it against 

 a stout support, made of iron or wood, several feet high, and when 

 it gets to the top encourage it to become bushy by frequent pinching. 



Propagation. Increase in stock is sometimes attempted from 

 portions of the roots cut into small pieces, but unless certain that 

 the plant is on its own roots this is a dangerous practice and has re- 

 sulted in much disappointment, as the resulting plants may turn out 

 to be nothing but the native C. radicans, on which C. grandiflora is 

 frequently grafted. After these root cuttings make considerable 

 growth it is quite a difficult matter to tell whether they are C. 

 grandiflora or the native species, so closely does the foliage of the 

 two species resemble each other. Those on roots of C. radicans 

 make plants quicker than from root cuttings, or from cuttings of 

 the green or dormant wood. Cuttings of the branches are a trifle 

 difiicult to manage at any time, but the ripened growths of young 

 plants will give the best results, as then the wood is not nearly 

 so thick and pithy as in old specimens. 



CARDIOSPERMUM. This is the Balloon Vine, so caUed 

 from the appearance of the seed vessels, which are very much in- 

 flated. The seeds of C. Halicacabum, the common species, should 

 be sown in semi-wild places. They are sometimes sown so they 

 may climb on wire fences. The plants ripen a very large quantity 

 of seeds, and they may be sown where the plants are to grow. 



CISSUS. No other vine approaches C. discolor inspfar as the 

 beauty of its foliagQ is concerned. The leaves are reddish on the 

 lower surface; on the upper surface the color is bright velvety green 

 mottled with silver; stem red. It is usually grown in a warm
