The species cultivated are : 1. J. armUlaris, 

 Obtuse-leaved Jacquinia; 2. J. ruscifoUa, Prick- 

 ly Jacquinia. 



The first is a very elegant upright shrub, sel- 

 dom more than four or five feet high: the trunk 

 round, thicker, and knobbed where ihe branches 

 come out, covered with an ash-coloured bark ; • 

 the branches four or five from each joint to- 

 wards the top, in whorls, spreading, stiff, round, 

 grooved, brittle, hoary, subdivided, and form-

the racemes terminating, commonly shorter 

 than the leaves, about two inches long, solitary, 

 erect, loose, simple, seven-flowered, or there- 

 abouts : the peduncles scattered, spreading, 

 one-flowered : the flowers small, stiffish, white, 

 smelling like Jasmine, and retaining their sweet 

 scent several days. It is a native of South 

 America, flowering in February and March. 



The second species is a shrub three feet in 

 height, having the habits of the first; but it 

 differs in the leaves being lanceolate, acuminate, 

 pungent, extremely stiff", and one-flowered. It 

 is a native of South America, flowering in 

 January and February. 



Ciiliure. — These plants are capable of being 

 increased by sowing the seeds, procured from 

 their native situation, in pots of light earth, in 

 the spring season, plunging them in a bark 

 hot-bed. When they have attained a few- 

 inches in growth, they must be removed into 

 separate pots, and be replunged in a hot-bed 

 in the stove, where they must be constantly 

 kept. 



They may likewise be raised by planting cut- 

 lingsofthe youngshoots, in potsof the same sort 

 of earth, in the early spring, plunging them in 

 the bark hot-bed, as in ihi' other case ; but in 

 this way they are raised with difiicully. 



They afterwards require to be carefully ma- 

 naged, by having little water given in the win- 

 ter time, but a free admission of air during the 

 hot summer season, and occasional refreshings 

 of water. 



They afford variety in stove collections.
