1. Ambrosia Trifida; Tri/ul-leaved Ambrosia. Leaves 

 three-lobed, serrate. Grows eight or ten feet high ; it is a 

 common weed in North America, and is only preserved by 

 the curious in botany. The seeds, though sown in spring, 



seldom come up till the second year, when they may be 

 transplanted into a moist rich soil, every way four or five feet 

 apart. If suffeved to scatter their seeds, they will vegetate 

 in the following spring. 



2. Ambrosia Elatior ; Tall Ambrosia. Leaves pinnatifid ; 

 racemes panicled, terminal, smooth. It is an annual herba- 

 ceous plant. Native of Jamaica, where it is found in barren, 

 sandy, and rocky situations, by the sides of rivers, in the 

 southern parts of the island. It flowers there from February 

 till June, but with us from July to the end of August. This 

 plant has the appearance and taste of Wormwood ; and will 

 thrive, but not produce good seed, in our open air. 



3. Ambrosia Artemisifolia ; Mugwort-leaved Ambrosia. 

 Leaves bipinnatifid; the first leaves attheorigin of the smaller 

 branches undivided, and quite entire. The primary stem is 

 scarcely more than a foot high. Native of America. 



4. Ambrosia Maritima ; Sea Ambrosia. Leaves uiultifid ; 

 spikes solitary, hairy, subsessile. Rises about two feet and a 

 half high ; the leaves emit a strong odour upon being han- 

 dled; the spikes of flowers are axillary. It is not remarkable 

 for beauty, and seldom perfects its seeds in England. Found 

 in Cappadocia, Tuscany, &c., on sandy shores. 



5. Ambrosia Arborescens ; Tree Ambrosia. Leaves pin- 

 natifid, hirsute; racemes solitary, terminating ; stem shrubby. 

 This species grows to the height of ten or twelve feet, with 

 a woody stem dividing into several branches. Perennial. 

 Native of Peru. It may be propagated by cuttings or seeds ; 

 the former planted in a shady border during any of the sum- 

 mer months, and well watered. The seeds when sown in 

 the spring seldom appear till the spring following.
