 the shrubby exotic kind for the stove. 



It belongs to the class and order Pentandrta 

 Monogi/nia, and ranks in the natural order of 

 Dumosee. 



The characters are : that the calyx is a five- 

 leaved perianthium : leaflets roundish, concave, 

 Eermanent : the corolla is one-petalled : tube 

 ell-shapcd, ventricose, longer than the calyx : 

 border ten-cleft : divisions roundish, of which 

 the five interior ones are shorter: the stamina 

 have five awl-shaped filaments, arising from the 

 receptacle : anthers spear-shaped : the pistillum 

 is an ovate germ : style the length of the sta- 

 mens : stigma headed : the pericarpium is a 

 roundish acuminate berry, one-celled : the seed 

 single, roundish, and cartilaginous. 



The species cultivated are T I. J. armilUiris, 

 Obtuse-leaved Jacquinia; 8. J. ritscifolia, Prick- 

 ly Jacquinia. 



The first is a very elegant upright shrub, sel- 

 dom more than four or five feet liigh: the trunk 

 round, thicker, and knobbed where the brant Irs 

 come out, covered with an 'ash- coloured bark : 

 the branches four or five from each joint to- 

 wards the top, in whorls,' spreading, stiff, r< and, 

 grooved, brittle, hoary, subdivided, and form- 

 ing altogether a neat globular head : the leaves 

 scattered, alternate, petioled, clustered towards 

 the ends of the twigs, wedge-shaped, ovate, 

 obtuselymargined, quite entire, reinless, smooth, 

 pale underneath, with very minute black dots :

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. 



Culture. — These plants arc 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 rcplunged in a hot-bed 

 in the stove, where they must be constantly 

 kept. 



They may likewise be raised by planting cut- 

 tingsorthe young shoots, in pots of the same sort 

 of earth, in the early spring, plunging them in 

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

 this way they are raised with difficulty. 



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.
