earliness and productiveness; the varieties of 

 late introduction are undoubtedly superior to 

 the older sorts, earliness and solidity being 

 the great desiderata. Tomatoes are now ex- 

 tensively grown for canning, and many 

 thousands of acres are used in growing them 

 for that purpose. They are also forced advan- 

 tageously for winter use, bringing good prices 

 till the crop from Florida comes in.

A small genus of very beautiful, ti'ailing 

 annuals and perennials, natives of China and 

 the East Indies. For the green-house or con- 

 servatory these plants, with their numerous, 

 dark-purple flowers, are a great attraction. 

 They also succeed well in a moist, shady bor- 

 der, but "will not endure our hot, sunny 

 weather. They are all readily increased by 

 cuttings or from seed. T. Fournieri, is an up- 

 right-growing plant of branching and grace- 

 ful habit, with a profusion of beautiful violet 

 flowers. T. Bailloni, introduced in 1878, is 

 an entirely distinct species, having deep-yel- 

 low and maroon-colored flowers. All make 

 e.xcellent basket or vase plants. They must 

 be kept at a temperature, in winter, of not 

 less than 60° at night, and they are at all 

 times impatient of being chilled. Propagated 

 by seeds or cuttings.

 arrangement of plants under the title of " In- 

 stiluttones Ret Hebarim," and other botanical 

 works, from 1694 to 1717 ; his first work, the

 ripened wood in sand.

 dendron, a tree ; alluding to the poisonous 

 nature of the fruit. Nat. Ord. Apocynacem.
