THE GREEN-HOUSE CATALOGUE. 335 



CA^CTEiE. 



Ce^reus flagelliformis, B.M. 17, a creeping succulent 

 from Peru, without leaves, but with fine deep red flowers. 



C. specioshsimus, large and beautiful flowers. 



Epiphy^llum specidsa, pale red showy flowers. 



Ca^ctus opuntia^ Indian Fig, B. M. 1577, a prickly suc- 

 culent from the South of Europe, which has no beauty in 

 its flowers, but produces a fruit sometimes eaten by con- 

 noisseurs. 



These plants are of the easiest culture in dry rich soil. 



SAXIFRA^GEiE. 



Hydra^ngea hortensis, B.M. 438, a frame undershrub. 

 from China which produces very showy flowers from April 

 to October. It requires a light rich soil, large pots^ to be 

 often shifted and parted, and abundance of water when in a 

 growing state. 



H. quercifolia, B. M. 975, a frame-shrub from Florida, 

 of much less beauty than the other, but requiring similar 

 treatment to cause it to flower freely. 



Saxifra'ga sarmentosa, B. M. 92, is a perennial, with 

 succulent leaves and very productive of red stolones, from 

 China : it grows in sandy soil, and its stolones and plantlets 

 hang down from the pot in a singular and pleasing manner. 

 It flowers in June and July, and is very hardy. 



There is a number of frame-plants which belong to this 

 genus, but they are chiefly natives of Britain and Switzer- 

 land, and are, in correct language, frame Alpines. They do 

 not therefore belong to the green-house. 



Tiare'lla biterndta, a frame-perennial from Carolina, 

 which flowers in May and June, and grows readily in loam 

 with a little peat.
