There is a variety which is procumbent, with smaller flowers. 



The third has a shrubby stalk a foot high, sending out several 

 branches: the leaves very narrow, coming out in clusters, but on the 

 flowering branches broader and longer: the flowers at the ends of 

 the branches, erect, on long slender peduncles: the calyxes acute- 

 pointed: the petals large, entire, white, but before the flowers open 

 pale yellow: they appear in July, but the seeds seldom ripen in this 

 climate: the flowering stalks decay in the autumn, but the lower 

 s hrubby part continues with the other branches all the year. It is a 

 native of Spain, &c. 



The fourth species forms, if not a tree, as its name implies, 

 a shrub of the height of several feet: it begins to flower in March, 

 and continues flowering to the close of summer; but has not yet 

 produced seeds in this climate. It is a native of the island of 

 Candia. 



The fifth has a suffruticose stiff stem, a foot high, round, with 

 simple branches: the leaves arc sessile, upright, even, generally 

 shorter than the internodes: the flowers in a terminating umbel, 

 which is four or five cleft, with dichotomous rays: the petals are yel- 

 low with villose claws, and turning tawny: the calyx acuminate and 

 rugged at the edge. It is a native of Africa, flowering in June 

 and July. 



Culture. These plants may be increased by seeds and layers, or 



cuttings. 



The two first sorts are raised by sowing the s^eds in the early 

 spring months, as March or the following month, the former in fields 

 or plantation-grounds, where the soil is fresh, good, and well reduced 

 into order by frequent digging over, or ploughing and harrowing, in 

 narrow drills, or broadcast, and raked or harrowed in with a light 

 harrow ; the plants being afterwards kept perfectly clean from weeds 

 by repeated hoeings. 



Towards the end of August, when the plants have attained their 

 full growth, and begin to turn yellow at bottom, and brown at top, 

 and their seeds to ripen, it is proper time to pull them ; though, if it
